　　Xinhua News Agency, Tokyo, November 23rd (Reporter Ma Caoran, Qian Zheng) Japanese nonferrous metal giant Mitsubishi Materials Co., Ltd. announced on the 23rd that its subsidiaries Mitsubishi Electric Wire Industry and Mitsubishi Shentong had falsified product data, and the number of affected enterprises reached 258.

　　The announcement pointed out that the number of rubber sealing rings produced by Mitsubishi Electric Wire Co., Ltd. from April 2015 to September 2017 was found to have tampered with the data, reaching about 270 million, involving 229 customers. Among them, there are 70 aerospace customers. This product is widely used in automobiles, ships, aircraft engines and other equipment. Unqualified products involve ships and aircraft engines of the Japanese Self-Defense Force.

　　The copper products produced by Mitsubishi Shentong Ruosong Manufacturing Co., Ltd. from October 18, 2016 to October 17, 2017 had data tampering, and the problem copper products reached 879 tons, involving 29 customers. This material is mainly used in automobile industry, and Mitsubishi Shentong tampered with the most important strength data.

　　Mitsubishi Electric Wire and Mitsubishi Shentong discovered the problem as early as October this year, but they did not announce it to the public, which was strongly criticized by the outside world.

　　In addition, Mitsubishi Aluminum, a subsidiary of Mitsubishi Materials, was also exposed to data fraud. However, the company said that it has confirmed the product quality and safety to all customers and did not disclose more information.

　　This is the second time that Japanese manufacturing companies have exposed data fraud scandals. Previously, Kobe Steel Works was also exposed to product data fraud, while Nissan and Subaru were exposed to "quality inspection doors". The product quality control that Japanese companies were proud of was repeatedly questioned by the outside world. Some analysts pointed out that data fraud has the risk of expansion within the Japanese non-ferrous metal industry.

　　Mitsubishi Materials is a Japanese nonferrous metal giant, which was reorganized by Mitsubishi Metals and Mitsubishi Mining in 1990. In fiscal year 2016, the operating income reached 1.3040 trillion yen, the net profit was 28.3 billion yen, and the number of employees reached 25,000.

Absrtact: Layout is the "face" of a newspaper, which plays an irreplaceable role in content dissemination. Focusing on giving full play to the special functions of military newspaper layout in the all-media era, this paper, based on the practice of news arrangement and the dissemination of selected works of China News Prize in recent years, explores the methods and paths of military newspaper layout innovation from three aspects: creating "visual storm", expanding multi-form information and highlighting media personality characteristics.

Keywords: China Prize for Journalism; News arrangement; Layout innovation; Military newspaper

The layout is the "face" of the newspaper, the visual presentation of the content, with special functions such as reading guidance, guidance, signs, etc. It is the exhibition place of newspaper ideas and plays an irreplaceable role in content dissemination. For military newspapers, it is their duty and mission to innovate the way of expression and communication based on content construction, carefully prepare the layout and hold the position of public opinion. Innovation is the first driving force to lead development, and innovation is the spiritual characteristic of the supreme leader’s cultural thought. When inspecting the People’s Liberation Army newspaper, President Xi clearly pointed out that content innovation, form innovation and means innovation are all important for news media, but content innovation is fundamental.

In the all-media era, content innovation needs the service guarantee of formal innovation. Focusing on giving full play to the special functions of military newspaper layout in the all-media era, this paper, based on the practice of news arrangement and the dissemination of selected works of China News Prize in recent years, explores the methods and paths of military newspaper layout innovation from three aspects: creating "visual storm", expanding multi-form information and highlighting media personality characteristics.

First, powerful: create a "visual storm" to attract more attention.

A good news layout is the unity of politics, news, ideology and artistry.

(A) highlight the weight, highlighting the political nature

?Turn it into a sharp ideological weapon and exert great power.

(B) outstanding attitude, reflecting the orientation

On February 2, 2016, the first edition of the People’s Liberation Army Daily won the second prize of the 27th China News Award. This edition focuses on the establishment of a war zone, an important event of national defense and military reform, and records this important historical moment with strong layout language and pictures. The layout highlights the key points, strengthens the transmission of important information and the visual impact of the layout, and highlights the style of big newspapers. Coincidentally, the August 5, 2022 edition of the People’s Liberation Army Daily, because of its clear stand, highlighted the weight and strength of the news and caused strong repercussions inside and outside the military. At that time, Pelosi, then Speaker of the United States Congress, insisted on visiting Taiwan, China despite China’s obstruction, and our army successfully held a joint combat training in the sea and airspace around Taiwan Island. The People’s Liberation Army Daily reported on the training in a run-through layout. The layout of the layout is concise, and the core facts are highlighted, which fully shows that our army is fully determined and capable of maintaining the motherland’s reunification and defending national sovereignty and territorial integrity. Practice shows that layout language is the natural expression of media’s position, viewpoint, emotion and aesthetic vision. As the mouthpiece of the Party, in the face of hot topics and sensitive issues, the mainstream media of the army should focus on making the layout an effective increment of content combat effectiveness, dare to speak out, speak out in time and be good at speaking out; It is necessary to make the news that should be done bigger and bigger, promote the supply of high-quality content, and ensure that the layout is coordinated in one go; Let the layout language have enough impact, clarify the facts and guide public opinion.

(3) Highlight emotions and increase appeal.

On July 31st, 2017, Edition A6 of Jinan Daily won the third prize of the 28th China News Award for newspaper layout. It stands out from its unique perspective in the competition of the same topic layout reflecting the 90th anniversary military parade. This page makes a fuss about the change of the detail that "the angle of military parade salute is raised from the original 15 degrees to 30 degrees", and the headline "It’s not just pride to hold your head up 30 degrees" has a strong emotional color; Carefully selected banner photos showing the heroic spirit of the two soldiers make the finishing point, which echoes and sets off the title. This layout not only brings visual shock to the audience, but also fully shows the heroic feelings of the Chinese nation standing tall among the nations of the world, which arouses empathy among the audience. It can be seen that the layout has language, attitude and emotion. Newspaper layout is a highly political business and political work. On the one hand, the mainstream media of the army should keep up with the changes of the world, the times and the history, establish a global vision, lead public opinion and guide the work; On the other hand, it is necessary to adapt to the new aesthetic changes of the audience in the all-media era, and make good use of layout language such as words, lines and colors to convey layout information and emotions more accurately and effectively, so as to enhance the reading experience of the audience.

Second, useful: multi-form information expansion, so that content presentation rushed out of the "first scene."

In the era of all-media, for newspapers, we should not only insist on the content as king, but also expand the form and service to make the layout "informative", "useful" and "powerful".

(A diagram, visual expression to achieve easy-to-read and interesting reading.

In the era of all-media, readers’ reading methods tend to be fast, fragmented and visual. Pictures and illustrations have become the most important and dynamic elements in newspaper layout because they are more intuitive and impactful than words in information transmission. In recent years, many of the winning pages of the China Prize for Journalism have enhanced their expressive power by adding data, charts and other elements. For example, the award-winning page of the 33rd China Prize for Journalism and the 5-8 edition of Jiangxi Daily on October 27th, 2022 are special commemorative pages to commemorate the 95th anniversary of the founding of Jinggangshan Revolutionary Base. With the help of the large-scale sculpture of "Jinggang Red Flag", the layout highlights the visual effect, and skillfully strings together important nodes such as "Wenjia City’s decision-making", "Sanwan adaptation" and "getting rid of poverty" in the form of a timeline, so that readers can visually feel the past struggle, current self-confidence and future expectations. Practice has proved that in the all-media era, a picture is worth a thousand words, and the mainstream media of the military should be good at using pictures to speak on the layout, so as to meet the aesthetic requirements of the audience in the era of reading pictures and make the news more readable and enjoyable; We should be good at arranging the relevant data in the news visually by means of charts, so that the boring and difficult data can be seen at a glance and arouse readers’ interest in reading; It is necessary to make it clear that the chart not only has the function of beautifying and activating the layout, but also is an independent and effective form of news reporting, strengthen the awareness of secondary processing, and help the transmission of its deep value through integrated refining and innovative presentation.

(2) Continuous version, carrying more content to create more space.

Of the six pages won in the 33rd China Prize for Journalism, five are consecutive pages. According to the data, in the past five years, 32 pages of the China Prize for Journalism have won awards, of which the single edition accounts for less than 25%. Continuous edition (all-page edition and cross-page edition) has become an important choice for newspapers to improve their communication power and influence. Take the award-winning page of the 32nd China Prize for Journalism and the 10-11 edition of the People’s Liberation Army Daily on July 1, 2021 as an example. This edition presents several classic moments of the People’s Army in the century since the founding of the Party in hand-painted form, with a clear theme and lofty ideas, which extends the sense of historical depth and makes readers feel refreshed. It can be seen that compared with ordinary single edition, continuous edition breaks the convention, makes the vision more impactful, can carry more content, and can better reflect the editing concept, thus producing a strong effect, so it has become the best choice for many newspapers. Some experts believe that this is also a useful exploration for newspapers to take the high-quality route and improve the quality and efficiency of communication in the all-media era. This enlightens us that in the all-media era, military newspapers should not only face the "fast" challenge brought by new media, but also give full play to their own strengths and work hard on the word "deep". We should focus on major themes, in-depth reports, elaborate designs around grand narratives; Change from "information paper" to "attitude paper"; Change from "design paper" to "collection paper".

(C) media integration, so that the layout "move up" and "live up"

In the all-media era, the layout language is more diverse. It is also an effective way to attract and retain the audience’s attention by making the layout "move" and "live" through the linkage of newspapers and networks. For example, in the winning pages of the 30th China Prize for Journalism and the 6-7 edition of Science and Technology Daily on October 1, 2019, when reporting the scientific and technological achievements made in the 70 years since the founding of New China, a QR code was added to the pages, and after scanning, the video of "70 years condensed into 24 hours" distributed synchronously by the newspaper can be watched. This innovation enriches the connotation of the layout and embodies the idea of media integration. For another example, the Liberation Army Daily, published on August 5, 2022, embeds the two-dimensional code of the video of the training site in the layout, which makes the news information richer and more comprehensive and meets the needs of the audience. It can be seen that in the all-media era, it is far from enough for newspapers to hold their ground in the flood of information. It is also necessary to expand information through media integration, broaden their horizons to below the appearance of news facts and outside the scene, and explore and explore more vital and inspiring three-dimensional pages.

Third, interesting: highlight the characteristics of media personality and enhance user stickiness.

Layout is an important part of the newspaper’s personality and style, which always plays the role of influencing readers and guiding public opinion.

(A) minor issues, tell a living story with details.

The second prize of the news layout of the 31st China News Award and the T7 edition of Xinhua Daily on April 14th, 2020, Thanks to You, the mountains and rivers are safe-paying tribute to the "epidemic" hero of Jiangsu’s aid to Hubei War, still seem to be a layout with special communication value. At that time, in order to welcome the triumph of the last batch of medical workers from Jiangsu who assisted Hubei, Xinhua Daily specially planned to launch a special tribute issue. As the cover of the special issue, this edition is carefully designed to outline the image of a well-armed medical worker with the names of 2,813 medical workers from Jiangsu who aid Hubei. Each name is regarded as a "point" in the picture, and they are connected in series by a "curve", and finally they converge into a meaningful "face" image. This treatment is meaningful: the success of the "epidemic" depends on specific people, and each person has a different story, thus achieving good communication results. Storytelling is the most effective communication. On the one hand, the mainstream media of the military should insist that content is king and continuously enhance their ability to provide content; On the other hand, we should pursue the harmony between content and form, strive to achieve the unity of form and spirit, and tell vivid stories with details; In particular, we should pay attention to digging points, cutting hot spots, falling points skillfully and tearing points, so that positive energy can generate large flow and good sound can become the strongest sound.

(2) Make the past serve the present, and the national wind ignites the new wind.

The prize-winning page of the 31st China Prize for Journalism and the 6-7 edition of Zhejiang Daily on November 23rd, 2020 were published at the opening of the "Light of the Internet" Expo in 2020. This edition takes the traditional "window" in China as the theme, and combines the unique "window lattice" element of Wuzhen water town with the new mission and new requirements of "important window" in Zhejiang. Through the image of "window" on the page, we can see the street view of Wuzhen and the Light Expo of the Internet, which makes the page have a sense of historical depth of blending ancient and modern, attracting people’s attention. After two years, on November 1st, 2022, the 6-7 edition of the newspaper won the 33rd China Prize for Journalism again with its strong national style and ingenious ideas. On this page, which shows the arduous course and great pioneering work of China’s space dream, the editor skillfully connects Su Shi’s words and images of "Palace Que in the Sky" with China Space Station across time and space, combining ancient and modern, and combining dreams with reality. Especially in the lower left corner of the layout, Su Shi is wearing VR glasses, looking up at the starry sky and singing "When did the bright moon ask the sky about the wine? I wonder what year it is in the palace palace tonight". The unique layout narrative method has injected poetic romance with Chinese style into serious scientific and technological topics, which is unique in many layouts with the same theme and has gained excellent communication effect. This enlightens us that in the all-media era, news content transmission is no longer the only pursuit of newspapers. It is necessary to comprehensively use richer editing methods in reporting, integrating national culture, aesthetic concepts and the value of the times, so that the audience’s reading can be changed from simple information acceptance to reading enjoyment based on understanding.

(C) associated with their own, related to the crowd.

In the all-media era, information is overloaded and attention becomes a scarce resource. Faced with a large amount of information, people will subconsciously pay attention to what is related to them, which is more familiar or interesting. Newspaper layout not only needs to carry forward the main theme and spread positive energy in a way that the audience likes and hears, but also faces the problem of connecting the content and expression form with the antenna and connecting them with the audience’s interests. The exploration of the winning pages of the 32nd China Prize for Journalism and the 2nd edition of People’s Daily on July 19th, 2021 is quite instructive. This edition focuses on the major theme of "achieving the goal of the first century-building a well-off society in an all-round way in China". In the way of presentation, it vividly shows the changes with 16 groups of data that best reflect the people’s sense of gain, happiness and security, and has both visual impact and ideological persuasion, making the boring and difficult data clear at a glance, narrowing the distance with the audience and achieving good communication effects. It can be seen that in the all-media era, the mainstream media of the military should work hard to show their own characteristics and improve the recognition and dissemination of newspaper pages. It is necessary to bring about a new release of narrative energy through the new development of layout means; It is necessary to enrich the new expressive force of two-dimensional space style and enhance the user’s stickiness; It is necessary to build news pages into witnesses of history and make newspapers readable, hidden and enjoyable.

　　Cctv news(Reporter Wei Junhao) As one of the oldest characters in the world, how did Chinese characters come into being? On February 19th, "Freehand brushwork in China — — Exploring the Origin of Chinese Characters "The online theme propaganda interview group went into Nanle County, Puyang City, Henan Province, to explore the origin of Chinese characters and feel the profound Chinese culture.

　　Cang Xie Cultural Museum in Nanle County, located in Shiguan Village, Liangcun Township, 20 kilometers northwest of Nanle County, has Cangjie Ling and Cangjie Temple, which was specially built to commemorate Cang Xie.

　　According to relevant records, Cang Xie was the official historian of Xuanyuan Huangdi. "Before there were no words, the tribes at that time mainly made notes by knotting knots, memorabilia and small things. With the expansion of the Yellow Emperor tribe, Cang Xie couldn’t remember what happened in big things and what happened in small things, and needed a new method of keeping notes urgently. Since then, Cang Xie has watched the changes of the sun, the moon and the stars, and watched the changes of the forms of all things, invented our oldest pictograph, and opened a new chapter in Chinese culture. " Pang Xingang, a lecturer at the Cang Xie Cultural Museum, explained.

　　"Cang Xie created many words in his life, but now there are only 28 words left." Pang Xingang said that these 28 words are pronounced as: "Wu Si A and B, who are friends in the first place, stop in the world, and have a glorious reputation. They are home to each other, respected by Chishui and attacked by Ge Mao." Under the leadership of Emperor Xuanyuan, he defeated Chiyou, United all tribes, lived and worked in peace and contentment in the Yellow River valley, and agricultural civilization began.

　　With the general form of Chinese characters, the characters made in Cang Xie gradually made them easier to remember and write, and gradually evolved from simple symbolic forms into modern Chinese characters that we are familiar with. The creation of characters by Cangjie is of great significance to the evolution of China characters and the development of China culture. He is also known as "the ancestor of Chinese characters", "the father of the three religions" and "the Sect of All Saints".

　　In 2010, the United Nations designated "Grain Rain" in the 24th solar terms of the lunar calendar as Chinese Day to commemorate the contribution of Cangjie, the ancestor of Chinese characters.

　　Although Cang Xie has been buried under the loess of Nanle, the Chinese characters he created are timeless and have become the most meaningful and profound human language.

According to the report of "Governor of Chang ‘an Street" in WeChat WeChat official account on June 3, Li Jianmin, deputy mayor of Ankang City, Shaanxi Province and deputy bureau-level cadre, died of sudden illness in Xi ‘an on the night of May 28, when Li Jianmin, deputy mayor of Ankang City was on a business trip, at the age of 54.

The bad news reached Bin County that night. Then, thousands of people rushed to Kaiyuan Square in the county from all directions and gathered under the Binta to mourn Li Jianmin. People hung up the tent of "Secretary Jianmin walked all the way" on the tower, and lit candles on the ground to mourn.

Li Jianmin

On May 28th, Li Jianmin, vice mayor of Ankang, died of sudden illness while on a business trip, which aroused social concern. Many people care about his funeral, but they accidentally found this mansion in his hometown of Zhidan County. Today, an article entitled "We Met the" Mansion "in Li Jianmin" exploded the Internet.

How luxurious is the mansion in Li Jianmin?

There are four caves in the yard, one for him and two for his brother. Six houses with ceramic tiles were built two years ago when immigrants moved, and the state subsidized half of them and paid half of them themselves.

The room is still a blank cement wall.

The only electrical appliance is the washing machine.

You still use such a big closet.

Jiao Xiaofeng, the boss of brilliant real estate, Shi Aiqun, the former national first-class announcer of Binxian TV Station, and others burst into tears after seeing the house.

Jiao Xiaofeng cried and said, "People say that Secretary Li is not greedy because he is not poor in money. What is this? Is this called having money? "

Lu Xiaoping, a national moral model, said: "We help the poor all day. Look at the secretary’s family. How many years have we worked with the secretary? I don’t know if the secretary lives in such a house. I don’t know if the secretary’s family has not been lifted out of poverty."

People in Liu Zhidan Memorial Hall said that Li Jianmin was having a NPC session when her mother died, and she went home directly after the meeting. A boss of Binxian Winery brought a load of wine, and Li Jianmin asked her to pull it back, saying that if you dare to pull it back, I will spare you.

"Secretary Jianmin, go all the way"

Chang’ an Street Governor APP found that after the death of the deputy mayor, it was not only Ankang, but also in Zhidan, Yanchuan, Wuqi, Binxian and other places where he had been in power, countless people spontaneously went to mourn him, and the scene turned into a sea of tears, which was moving.

According to the China Business Daily, after the news of Li Jianmin’s death reached Bin County, the mobile phone circle of friends of local people was quickly screened by Li Jianmin, and the screen was full of words such as sadness, regret, nostalgia and gratitude. Thousands of people rushed to Kaiyuan Square in the county seat from all directions and gathered under Binta to mourn Li Jianmin. The masses hung up the bill of "Secretary Jianmin walked all the way" on the tower and lit candles on the ground to mourn.

There are at least hundreds of wreaths at the scene, all bought by the masses themselves. There are sanitation workers, female middle school students and veteran cadres in their 80 s who come to see me off. A boss selling rabbit meat came with his daughter. He still remembers the scene when Li Jianmin forced him to give him money after eating in his small restaurant.

In July 2006, Li Jianmin was transferred from Wuqi County to Binxian County and worked there for 10 years until he left in February 2015. The local people said: "Li Jianmin is good, just look at what he has done. Kaiyuan Square and Jinghe River embankment are real examples." The urban environment in these two places has been greatly improved, which is Li Jianmin’s real achievements after working in Binxian County.

National poverty-stricken counties have become the top ten counties in Shaanxi

Before 2006, Bin County was still labeled as a "national poverty-stricken county". Here, Li Jianmin showed clear thinking and foresight, and led Bin County to become one of the top ten counties in Shaanxi in just four years.

At that time, the office building of the county party committee and county government in Bin County was nearly 30 years old, with broken doors and windows, old tables and chairs, peeling walls and leaking toilets. "The office conditions are poor, and there is no face at all!" Many civil servants complained about the office building at that time, hoping that Li Jianmin could make a decision and take money to renovate it.

"Money should be spent on education first!" Li Jianmin set the tone when he first arrived. He believes that for a poor county, developing education and cultural construction is the most basic work.

Under this development idea, Binxian education has sprung up, taking the lead in solving the "Nine-Year Plan" debt in Shaanxi Province and implementing the 15-year free education policy from kindergarten to high school.

The poverty in Bin County is also related to the flood of Jinghe River. Jinghe River passes through Binxian County. There are no riverbanks on both sides of the river all the year round, and floods occur every year. Li Jianmin personally led a team to investigate and decided to spend 320 million yuan to start the flood control project.

Poor counties spend so much money to build dikes, which immediately leads to overwhelming doubts. Before the controversy stopped, a heavy rain gave Binxian people the answer.

On July 23, 2010, the rainstorm raided Bin County, and the water level has exceeded 1 meter, and the county seat is about to be destroyed. At 10 o’clock in the evening, Li Jianmin stood in the chest-deep flood to dispatch excavators and forklifts, and quickly dredged three tributaries leading to the Jinghe River. After an hour, all the floods in the city were drained away, and the newly built riverbank stood still in the test.

Since then, the voice against the dike repair has vanished.

My son has a bad temper, which hurts everyone’s forgiveness

Not only in Bin County, but also in Zhangqu Township, Zhidan County, Li Jianmin’s hometown, the people have been thinking about his goodness so far, and the most evaluation is "Good man!" Praise him for being an official without forgetting his roots. Under the planning of Li Jianmin, this once-closed village was wired and connected with tap water. The local people said, "We have an unexpected misfortune. Just let him know and there is no reason to fall into the ground."

In another place where I worked, Yanchuan, my old colleague commented that Li Jianmin was "extremely smart and had many ideas".

"Smart thinking" comes from solid grassroots research. Everywhere he went, Li Jianmin rolled up his trouser legs, and went from town to town to visit villages. Of the 705 natural villages in Yanchuan County, Li Jianmin visited 703. After on-the-spot investigation, Li Jianmin keenly discovered the great potential of jujube industry. He immediately mobilized Comrade Inoguchi to organize farmers and formed a model of "company+base+farmers". Statistics of Yanchuan County show that during Li Jianmin’s tenure, the planting area of red dates increased from 78,000 mu to 210,000 mu, which became an important pillar of the local economy.

To ordinary people, Li Jianmin always smiles at each other, but for those cadres who don’t do a good job, he only recognizes work and denies people. A Binxian cadre who worked with him said that Li Jianmin had never been vain in his work and did not talk about "routines". When checking the work, I always go to the fields to see for myself first, and then listen to the report. At the memorial service, his old father choked in public and said, "My son has a bad temper, which hurts everyone’s forgiveness."

　　Bath center, 24-hour ATM bank, underground parking, Internet cafe, KTV… … In recent years, some tourists choose these cheap and convenient places to spend the night in order to save money when traveling abroad. Recently, however, Red Star journalists found that some netizens shared their "coup" of saving money by staying overnight on a social platform, and even chose the overnight place in the emergency department of the hospital. They also said that big hospitals such as the top three hospitals are five-star hotels with intimate service and comfortable recliners.

　　In this regard, some medical staff working in the emergency department told the Red Star journalist that in the past work, people who did come to see a doctor by pretending to be sick generally did not deliberately expose them, and they would be treated according to normal diagnosis and treatment. The inspection should be advised to go back to rest and persuade them to leave. It is considered to be very unqualified for this kind of behavior that takes up the queue for medical treatment and medical resources. "If there are many such behaviors, the hospital will issue relevant regulations in the future, which will add trouble to those who really come to see a doctor."

　　Bloggers send "coup" to save money by traveling;

　　"You can pretend to be sick and go to the hospital for emergency treatment for the night."

　　Netizens criticized "guiding others to occupy medical resources"

　　Recently, a blogger posted on a social platform that if you can’t book a room for travel, you can register to stay in the emergency room of the hospital. According to the screenshot of the net transmission, the blogger created his own "small coup" to save money for overnight travel, and emphasized that big hospitals such as the top three hospitals are five-star hotels with intimate service and comfortable recliners.

　　The blogger also described in detail a series of procedures for registering and seeing a doctor in his post: registering at the emergency window of the hospital after 10 pm, taking blood pressure and temperature at the triage desk, washing after "confirming that he is not sick", lying that he coughed and was out of breath when seeing a doctor, and asking the doctor to prescribe oxygen instead of medicine, and staying in the hospital for the night at the price of 3 yuan per hour. The time of oxygen inhalation can be determined according to his sleep habits. "A total of 30 yuan can spend the night on the hospital lounge chair, and the nurse will help look after the luggage."

　　On October 9, when Red Star journalists searched the above-mentioned bloggers’ accounts on the platform, they found that they could not find the relevant accounts. However, by searching keywords on the platform, the reporter found that other bloggers still posted similar posts. According to a blogger, his company organized a very remote (local) physical examination, and decided to stay in the hospital because he couldn’t go back that day. At that time, the doctor immediately opened a hospital for him, or a single room.

　　▲ Another netizen shared the post "Where can I spend the night without staying in a hotel?"

　　The blogger also said in his post that the hospital fee is basically about one day in 60 yuan, but only when the beds are free, and a sick note can be issued. Later, when the blogger went to Hangzhou to play, he had a physical examination in a local hospital because he couldn’t find accommodation. "I was given an accommodation. I was called up at 6: 30 the next day and took a color ultrasound. I let me go. I spent 220 yuan before and after. The accommodation price in Hangzhou was not lower than that in 600 yuan that day."

　　Since the post of "saving money by spending the night in the hospital emergency room" was exposed, it immediately triggered a hot discussion among netizens. Many netizens left a message in the comment area, "This is guiding others to occupy medical resources, which will seriously interfere with the normal order of hospitals and the work of medical staff"; "Emergency overnight not only wastes medical resources, but also affects patients who really need emergency services. Can you sit still in the rest area here? " Some people also said, "Not to mention the need for doctors to judge the condition, all kinds of patients will be received all night, as well as the sounds of various instruments, all kinds of painful screams, and the lights will shine like daylight, so you won’t go even if you are asked to go" … …

　　▲ Reply from the platform involved

　　On October 10th, the Red Star journalist contacted the customer service (professional assistant) of the platform involved. The other party said that in this case, you can click the reporting option on the platform, and provide the relevant materials of the whistleblower according to the corresponding prompts on the page, and the corresponding Commissioner will follow up the verification. "The platform will take one or more of the following measures based on the facts independently identified by it, such as: limiting the scope of display, banning accounts, banning accounts, and pursuing legal responsibilities according to law."

　　Emergency medical staff:

　　Encountered pretending to be sick to see a doctor.

　　But it is almost impossible to achieve the goal of staying overnight at a low price.

　　"Emergency departments at home and abroad are roughly divided into five major areas, including pre-hospital emergency triage area, hospitalization observation area, rescue area, emergency inpatient ward (including general ward and emergency intensive care unit) and infusion area." Xiao Wei, a medical staff member in the emergency department of a third-class first-class hospital in Guangzhou, told Red Star that the day shift and night shift in the domestic emergency department are similar. The day shift is the normal administrative time, around 8: 00 -18: 00, and the rest of the time is night shift. "After the outpatient clinic is closed, the emergency department becomes busy, usually at noon and evening, as well as on the eve of holidays and during holidays."

　　Regarding the bed problem in the emergency department, Xiao Wei said that there will be beds in the rescue area and the observation area, but the number is not very crowded, and they all need to go through the formalities. "The emergency inpatient ward, like the inpatient department, needs hospitalization procedures to live. There are 5 beds in our infusion area, which are used by patients who need infusion. After transfusion, they must get up and lie down for patients who need it later. People who don’t need infusion are not allowed to lie down. " In addition, Wei also said that the general process of treating patients in the emergency department is: when patients arrive in the emergency department, there is a triage desk, and the nurses at the triage desk will evaluate the patient’s condition, roughly grade the condition by asking questions, measuring heart rate and blood pressure, and queue up for treatment according to the grading system.

　　"Patients who pretend to be sick have also encountered some. The triage nurse generally does not refuse to consult, and the registration will be hanged. However, if it is recognized that he is pretending, he will be told that he must queue up according to the order of diagnosis and treatment and cannot jump the queue. After it’s his turn to see a doctor, the doctor will judge his condition. It’s really fake, and he won’t open an oxygen inhalation or a bed for you to lie down for one night. " Wei said, because doctors also know that he is responsible for the patients in every bed he arranges, he also needs to make records and shift the next doctor, and so does the nurse. "It is easier for people who pretend to be sick to see it. Ask more questions, do some relevant physical examinations, open tests for him, and he will refuse to check. However, (medical staff) generally will not deliberately expose the illness, so they will still be treated according to normal diagnosis and treatment. The inspection should be advised to go back to rest and persuade them to leave. Even if there is a free bed, it is impossible to give him a night. "

　　In addition, regarding the aforementioned problems of being drunk and being hospitalized for physical examination, Xiao Wei admits that the control of being hospitalized in the emergency department is stricter than that in the general outpatient department, so the situation of being hospitalized in the emergency department through being drunk or being hospitalized for physical examination hardly exists in the emergency department. "Unless the condition of drunkenness is very critical, it will definitely be hospitalized for treatment. “

　　"This online ‘ Planting grass ’ I was a little shocked by the situation. It is not excluded that some people have done this and succeeded, but this situation generally does not appear in busy public hospitals. However, many hospitals are expanding now, and the new campus of some hospitals is indeed well decorated and equipped, and it is not excluded to open beds to live in order to generate income; Moreover, some young doctors are inexperienced. If people who come to see a doctor strongly demand to stay overnight even if they have not detected any problems, there are also empty beds. For safety reasons, doctors may think that he may have mental illness and let him stay for one night. " Wei told reporters that they had had patients with mental and sleep problems before, and only asked for oxygen and overnight stay, but the patient did have mental problems. "In short, the hospital emergency department generally does not refuse to consult, but it must abide by the order of diagnosis and treatment, because emergency patients will definitely give him priority in cutting in line. Moreover, sometimes in an emergency, such as a new patient who needs to be rescued, if there is a lack of beds, the emergency department does not rule out letting patients with mild illness give up their beds, take wheelchairs or seats first, and wait until the beds are turned around before returning them to patients with mild illness. "

　　"Patients with colds and fever usually need to leave after the fluid is lost, and they are not allowed to stay in the emergency room. If medical staff find that someone is pretending to see a doctor, they will continue to urge them to leave. " The medical staff in the emergency department of a second-class hospital in China also told reporters that in the past, there were cases in which patients broke into the emergency room for the night by themselves in the middle of the night, and the medical staff would drive away the people who occupied the beds during the morning rounds. "Under normal circumstances, all patients who saw a doctor in the emergency department, as long as they did not apply for hospitalization, would ask the patients to leave after the treatment, and would not be allowed to stay overnight. It is almost impossible for people without symptoms to want a bed in the emergency department through the normal medical treatment process to achieve the purpose of staying overnight at a low price in the hospital. "

　　The medical staff also said that doctors will diagnose the specific symptoms of patients and will not blindly meet the requirements of patients. I just want to take oxygen when I cough, so don’t prescribe medicine ’ In fact, not everyone is suitable for oxygen inhalation when coughing. Even if oxygen inhalation is allowed, it is only allowed for twenty or thirty minutes. After simple treatment, the patient needs to leave, and it is impossible to stay overnight. "

Introduction:

On August 24th, the latest issue of Horizon’s "Hello, Developer" Autopilot Technology Special Session was successfully broadcast in the Zhidong Open Class.

The special session was given by Dr. algorithm engineer Zhu Hongmei, Horizon Perception, with the theme of BEV Perception Scheme and Deployment Practice Based on Journey 5. This article is a record of the lecture session of this special session. If you need live playback and Q&A, you can click

Good evening, friends of the open class of Zhidong. I’m Perception algorithm engineer Zhu Hongmei from the horizon, and I’m honored to share with you today "Ji"BEV awareness scheme and deployment practice in Journey 5》。 I will introduce it from five aspects.

01

General introduction of BEV perception framework

With the release of Journey 5 in 2021, we designed the sensing prototype scheme of BEV based on Journey 5. The input is vehicle-mounted multi-angle image sequence or multi-mode signal, and the fusion of time and space dimensions is carried out within the network, so that the neural network can output the dynamic and static sensing and prediction results from a bird’s-eye view.

Below is a frame diagram.

The green background part represents the signal processing of pure vision, and the input is the images of each camera. After the first stage of model extraction, the image features are transformed into multi-view spatial fusion from BEV perspective. Then, the features of BEV are fused in time sequence, and then sent to the second stage for feature extraction on BEV; Finally, input it to the head part for the output of perceptual elements. If there is a Lidar in the system, it will also be connected to the Lidar point cloud. In the early stage, we will do rasterization coding processing, and we will also do time sequence fusion. Finally, we will do intermediate fusion with visual BEV features, and also send them to the second stage to output the perceptual elements on BEV.

The blue part is the closed-loop iteration that has participated in many rounds. Students who pay attention to the horizon should know that at the Shanghai Auto Show in April this year, this part of the content has supported the closed-loop demo display of real cars. In recent six months, we have expanded the function of "dynamic obstacle detection" in sensing elements. Based on it, we connected the head of Transformer to do the Track id, speed estimation and trajectory prediction of dynamic obstacles. The dotted line part is currently under development, and we also want to make full use of the dynamic and static sensing results on BEV to output the interactive elements of dynamic and static sensing, such as behavior prediction.

There are two main modes of pure vision scheme here. One is the 11v integration scheme for double Journey 5; The other is a single journey chip-oriented scheme, in which 7v for driving and 5v for parking are integrated. Today’s sharing mainly focuses on the integration of time and space in the visual scheme, the analysis of perceptual elements, and the introduction of dynamic, especially dynamic perceptual prediction end-to-end scheme and deployment.

02

Spatio-temporal fusion module and chip deployment

Firstly, it is introduced that the four-plane space fusion method is adopted at the end of the plate at present. It takes the xy plane of the self-propelled coordinate system as the basic plane, and adds three height planes on this basis, hoping to obtain more scene image information with different heights. Time series fusion is relatively simple. We will cache the features after time series fusion at the last moment, align the historical frames to the current frame by using the self-driving motion between frames, and fuse them with the spatial fusion features of the current frame, and then deconvolution them and send them to the following network structure for perceptual output.

So why do we use this scheme?

In the early stage of research and development, we also compared different spatial fusion methods. In the early stage, in order to quickly get through the process, we adopted the simplest method based on single plane IPM to get through the perception of the whole framework. After that, I went to find out the depth-based fusion and transformer-based fusion scheme on Journey 5. The assessment dimension is the delay in Journey 5, assuming that the prerequisite is to be able to independently run this model above 30fps on the single core of Journey 5 to design the corresponding network parameters.

There are two key parameters that affect the perceptual performance of BEV, one is the resolution of image feature in one stage, and the other is the fusion resolution on BEV. The fusion resolution on BEV is relatively direct, and the higher the resolution, the better the perception of some small targets and point elements. Image resolution determines the amount of information input in two stages.

Here is a lane line simulation diagram, and the physical dimensions of each lane line are the same. Because it is perspective projection, the farther the lane line is in the image, the fewer pixels it will have. BEV indexing image features is generally a process of reverse realization, while BEV is generally designed with equal resolution, such as 0.6 and 0.4 m Grid resolution. When the distant objects in the scene are indexed by the coordinates of BEV, the physical resolution of the pixels in the image is already lower than that on BEV, and at this time, feature duplication will appear on BEV, which is a common stretching phenomenon. Reflected in the perception, for example, the detection box may have the phenomenon that the target splits into a string, so the feature resolution in one stage is also very important.

We grab the middle column of pixels to simulate the contrast of Z-value changes between two adjacent rows of pixels in 2M image and 8M image at 50m. It can be seen that the physical range of the low-resolution image corresponding to two adjacent rows of pixels has changed by more than 2 meters. For a high-resolution image, its adjacent two pixels are only about 0.6 meters. Therefore, when looking at the fusion scheme, we should not only consider whether a single task meets certain accuracy requirements, but also consider the final deployment, because it is multi-task and different perceptual elements output, so we hope that the resolution of one-stage feature and BEV fusion can be higher.

From this point of view, the current structure based on Transformer can meet the requirements of Journey 5, single core and 30+FPS, and the first-stage resolution and the second-stage fusion resolution are relatively low, and the delay is too high under this condition. However, the depth-based fusion method is lower than single plane in one stage. In addition, one reason for not adopting it is that the depth-based deployment has made some specific improvements for Journey 5, reaching a two-phase delay of 9.6 ms. In the stage of prototype verification, the flexibility of carrying different numbers of cameras on the car is not enough, so we adopt the plane mapping fusion method at this stage. In the early stage, we used a single plane, but when we actually did the closed-loop verification, we found that the generality and robustness of camera parameters were not enough, and it was sensitive. Therefore, we improved it in the further research and development process. Through various tests and verifications, we finally adopted the four-plane fusion method, which can achieve a good balance between performance and delay.

For time series fusion, different time series fusion methods will also be compared in the early stage of research and development. The basic method is to align the historical BEV features to the current frame and use different fusion methods to do time series fusion. Here is also a comparison of the fusion of different frames, with the experimental data accumulated at that time to do 10 frames of verification. In the case of 10 frames, there is an improvement of 3.5 points compared with only space. For latency, it is only increased by 1ms because it is deployed in recurrent mode.

Similarly, we also compare the two methods of obtaining historical frames. One is to intercept historical information at equal time intervals, and the other is at equal space intervals. Equal time interval is to use the system timestamp to index and read the corresponding frame. Equal space interval is to calculate the translation distance with the movement of the vehicle, and then get the frame. Finally, we found that the performance of equal space interval of 6 frames is similar to that of equal time interval of 10 frames, and they can also be combined, but the improvement of more fused frames is not great. Therefore, in order to simplify the deployment, we currently adopt the time series fusion method with equal time intervals.

There may be some differences in the training and deployment of time series fusion. One is the Odometry used when aligning two adjacent frames. In order to make the training model performance consistent with the real vehicle deployment, one principle to be observed is that the model input should be consistent with the board signal as much as possible. We use Odometry of wheel speedometer to do model training, and do tests on Odometry obtained by different methods. It is found that if it is consistent with the inter-frame interval during training, then this factor has little influence. In addition, for example, historical frames are obtained at 100ms intervals, and the model trained with 10fps training data is tested at 10fps, 15fps and 30fps. The conclusion is that if there is a big difference between deployment and training, the index gap will be even bigger. The actual system frame rate is affected by the real-time load of the system, and it may not be completely aligned no matter how to set the inter-frame interval during training. Generally, the perimeter perception can be around 15fps, which can basically meet the functional requirements, and the range of 1.5 points is also acceptable. This part can also make the distribution of time series training data more abundant through some data enhancement methods, and alleviate such problems.

The other is that when the time series is being trained, if there is no specific optimization, with the increase of the number of frames, some OOM(Out of Memorry) problems may occur in the time series data, which leads to the slow training speed. The training method is to adopt the feature cache strategy to alleviate or avoid such problems. However, when deploying on the board side, considering the memory limitation of the board side and the bandwidth loaded back, the most streamlined strategy recurrent mode is finally adopted on the board.

Analysis of static and Occupancy perception elements

An important component of static perception is truth value. How did the truth value on BEV come from?

From the very beginning of research and development to the present, three static truth values have been used. At first, high-precision maps were used, and now the truth production link based on multi-mode is used on a large scale. At present, the local mapping results of pure vision are also involved in the training. The quality of the drawings is developed by our company’s special 4D-Label team. At the special session of horizon "Hello, developer" autopilot technology, Dr. Sui Wei, the head of horizon 4D labeling technology, also shared the "4D labeling scheme for BEV perception". If you are interested, you can review it.

For the algorithm, the algorithm students should be more involved in the formulation of labeling rules. Even if the truth value is brushed by the big model, the big model needs the truth value, so the labeling rules need the deep participation of the students of the perceptual algorithm, especially the actual test scenario is very complicated. A reference condition of labeling rules is the Lidar point cloud base map obtained by mapping, which is an intensity map on BEV, and then it can be labeled by referring to images or videos. For example, lane lines should be marked with colors, some functional attributes and some downstream functions that are necessary and cannot be obtained from the Lidar bottom map, all of which need to be combined with images. For pavement signs, they are usually unmarked rotating frames, and for those that need a clear direction, they need to be marked in an orderly sequence. The elements of parking are basically to mark parking spaces, wheel gears, speed bumps and so on by marking key points.

The output of the model corresponds to the annotation. The marked information will be preprocessed to generate the true value of the model. Only when the truth value is supervised output can the downstream functional requirements be met. The lane line output is the position and attribute of the example point column; The intersection point is the position and type of the point; Curbside is also the instance position and type; Pavement discrete signs are detection frames and types. These static perception elements are very rich. For the model scheme, there is a classification learning of foreground extraction, a regression learning of accurate position, and a learning of example features of lane lines. On the whole, the static perception scheme is relatively conventional. When analyzing, line elements such as lane lines will extract the foreground through the score of Class Map, then cluster the points through the Embedding similarity, and reverse the attribute features to index the corresponding features of these points.

For lane lines, in the actual software analysis, we should consider the delay on the software, roughly estimate the direction of lane lines through vertical points according to the preset, and do one-dimensional search along this direction to shorten the post-processing time of lane lines. Now our scheme is newly optimized, and it takes less than 3ms to deal with this part. The analysis of pavement signs, detection points or boxes at intersections is a set of CenterNet: card score→maxpolling→TopK→ attribute extraction → output.

For parking elements, parking spaces will output orderly corner position, occupancy and parking space type direction; The wheel stopper is an orderly end position and type; The underground locks and columns under the parking lot are all output by detection frames, which are the same as the analytical ideas of the previous points and line frames. The parking space here has two small head, one of which is to obtain the overall attributes of the parking space, such as its occupancy, and whether the parking space type is parallel or vertical. There is also a Local head to accurately estimate the corner of the location, because the accuracy of this corner of the location is very high. After getting a more accurate one, calculate the point matching with the rough corner position obtained under global. Because this point is orderly, you can just card a distance threshold. After matching, you can get an accurate corner coordinate by replacing the corner coordinate.

This is our performance. The 2D perception scheme of horizon has been polished for a long time before, which is equivalent to having a good reference baseline for BEV perception.

Compared with the 2D scheme, lane lines and road signs have a great improvement in ranging, such as lane lines in different distance sections, arrows and stop lines of road signs. For parking spaces, Horizon also has a pre-fusion scheme. Before being sent to the network, four fish-eye images are fused by IPM to get an IPM image covering 360 degrees around the car, and then integrated into the network to output parking spaces. Now BEV is introduced in the previous framework, and feature are fused inside the model. At present, there are also great improvements in these three class libraries.

Take a look at this video, which is a visual display of a high-speed lane line, with a wide dotted line, and then get off the ramp. Here is a diversion point, a change point between reality and reality, and the arrow represents the direction.

For the perception of parking space, a parking scene is chosen here, where the red line represents the entrance line, the yellow X represents the occupation, the yellow box is the pillar of the parking lot, and the grass green is the wheel stopper.

Let’s talk about the perception of Occupancy. First of all, Occupancy is a 2D occupancy graph based on Journey 5, which is a binary graph, where 0 means unoccupied and 1 means occupied. We call it Freespace internally. The traditional Freespace is image segmentation and post-processing to calculate the drivable area under BEV. It is more natural to do it on BEV, and output such a binary image directly on BEV. Its true value depends on Lidar segmentation model+detection model+threshold of cloud card height of multi-frame aggregation point to obtain some obstacles on the ground. Lidarseg mainly obtains the basic surface first, and takes the road plane as the drivable area; Lidar3D detection is to supplement the true value of dynamic obstacles in the white list.

The other output is Vismask. It mainly describes the area that the vehicle can see in the image at the current moment, and also uses Lidarseg model and 3D detection model. Image segmentation combined with back projection of point cloud can get the points that can be seen under BEV, calculate the ray according to the semantics and camera parameters, and then calculate the surface paved by the points that can be seen in the image in the self-propelled coordinate system, and then flatten them in the height direction of point cloud to get the visible Grid points on BEV. Why do you need 3D detection? Because when the ray hits the point cloud, it is a surface. We want the whole object of the surface boundary to be visible, so we need a 3D detection frame to supplement the object of the boundary, thus obtaining the true values of these two tasks. Perception model is a relatively simple binary classification model. Vismask’s 0 means invisible and 1 means visible.

Because these two tasks are dense outputs, when actually doing this on the board, its bandwidth occupation is relatively large. Usually, we will use a Run Length Encoding (RLE) to compress the result. For example, Freespace, as shown in the following figure, has the same values in a connected region. Run-length coding is used to reduce the bandwidth of the perceptual results transmitted from BPU of Journey 5 to CPU, and a final output binary image can be obtained by doing a back analysis in CPU.

Here is a visual video, and the bar on the left is a response to the fence. This is a specially built evaluation set, including strollers, fallen cones and so on. Here, Freespace is mainly to supplement the perception of non-standard obstacles. In addition, it is also useful to feed back the representation of roadside by Freespace when the downstream closed loop is used.

04

Dynamic Perception Predicting End-to-End and Chip Deployment

Let’s introduce the end-to-end scheme of dynamic sensing prediction and chip deployment.

The end-to-end model, as shown in the previous frame, is followed BEV3D several layers of Transformer decoder to output dynamic end-to-end elements. The multi-scale features extracted by BEV in two stages are reused, and there is a detection head of BEV3D, which regresses to the heatmap and the offset to the precise position to get the possible target position.

For Transformer head, it depends on how the Q/K/V of its input comes from the first layer. There is a construction part of the input. First of all, "q" is divided into detection query and Track query. Detect the position embedding； of query, which is the position parsed from BEV3D head and obtained by MLP; Context embedding is learnable and can be initialized randomly.

For the position embedding of Track query, the position of the previous frame will be used, and the self-vehicle motion between frames will be aligned to the current frame to eliminate the self-vehicle motion. Then, the position of the current frame is estimated by combining the speed estimation result of the previous frame itself, and the position embedding of Track query is obtained by MLP. Its context embedding was also randomly initialized and learnable at the beginning, which resulted in "Q".

"K" and "V" For BEV, there is a fixed mapping relationship between the pixel coordinates on BEV and the coordinate positions under VCS. Therefore, according to the position of the reference point, its pixel coordinates on multiple dimensions of BEV can be calculated reversely. Query also sorts from 0 to N-1, and it has an index, so that the difference between the two coordinates can be calculated into the mapping relationship between them. Then the warping operator, that is, the grid_sample operator, is used to reversely index the BEV region features, and then "K" and "V" are generated through MLP, so that the end-to-end head input is constructed.

One of the differences in Transformer here is that it improves the quantization and efficiency on Journey 5, and removes the MatMul matrix multiplication operator. Here, the commonly used Deformable attention is replaced by warping.

The output layer of end-to-end head is actually several MLPs. Among them, the output of trajectory and speed will pass through Memory bank in order to obtain historical information. The point of the trajectory output here is also the displacement between frames, and the velocity describes the position change of unit time between frames in the future. We think that these changes are not abrupt, but smooth, so we use historical information.

The embedding of history is composed of two parts. The first part is the Oddity of N historical frames and the embedding of query output by Transformer decoder of N historical frames will be stored in Memory bank. Query of the current frame, and pay attention to the time sequence of the current frame and the historical frame for each target. After that, self-attention will also be done among the targets, and finally we define it as Temporal embedding. In addition, speed embedding is added. How did it come from? That is, the position of historical frame N is transferred to the current frame through the odometry of the vehicle motion, and the position of the historical frame under the current frame is obtained, so as to eliminate the vehicle motion and obtain the inter-frame offset. Combining with the frame rate of the system, a time difference can be derived, and the historical inter-frame speed can be estimated. Similarly, after passing an MLP, the embedding of the speed can be obtained. By making a simple concat, the final historical embedding can be obtained and input to the trajectory.

After the model is output, some of it will be analyzed in CPU. For Track query and Detect query, the model output itself will analyze the position, length, width, height, orientation angle, Score confidence and so on. The function of track management is to screen out the Track query of the next frame. Two thresholds are set here. A higher threshold is to filter out the tracked query with higher confidence from all the queries, that is, the tracked query, and identify the newly generated target in the current frame. For the newly generated target, a current maximum id value of +1 is given, and its disappearance time is initialized to 0. For setting a low threshold, I want to recall those targets that have been tracked before, but have low confidence in the current frame due to occlusion and other reasons. If it can be greater than this threshold, and the disappearance time is not greater than the set time, it will continue to be preserved. If the time of disappearance (disp_times) has been greater than the threshold of the number of frames that can be dropped, we will definitely drop this target in this frame.

For the analysis of velocity, the model itself can be directly output, and kinematics post-processing will be added after it comes out. The "z" here is the length, width, height and speed (attribute) of the previous output, which we call observation. The model will also learn from the gain matrix of Kalman, avoiding calculating "k" on CPU, and finally giving the filtered state quantity to the downstream. Compared with the unfiltered operation, this operation has a 19% improvement in speed accuracy. From the visual performance, the speed does appear smoother after this. When updating the embedding of Track query in the next frame, the historical embedding generated in Memory bank will be used. The details of QIM will not be expanded, so you can refer to the implementation of MOTR.

Take a closer look at the performance of the end-to-end model. End-to-end comparison is only detection, tracking and speed estimation through post-processing. The baseline detection compared here is already 3D detection on BEV. Compared with the original 2D detection, it has obvious advantages in ranging. Blue and green are the vertical error percentages of 2D detection in different distance segments, and red and purple are BEV3D. It can be seen that the end-to-end model is more advantageous than BEV3D on the basis of this better baseline.

First of all, take a look at ranging and speed measurement. From end to end, ranging and velocity measurement have obvious advantages on three kinds of dynamic obstacles. The lower the error here, the better, and here is the percentage of error reduction, especially the speed advantage is particularly obvious. Trajectory comparison is a cascade model, its input is the dynamic post-processing of 3D detection on BEV, and some vector information of lane line static post-processing after environmental reconstruction, which is a separate trajectory prediction model. The end-to-end input is the image, and the direct output is the trajectory. Compared with the two, end-to-end has obvious advantages in the position error of this point series.

Here is also a visual video. The box in the picture is the target, the yellow line represents the horizontal and vertical speed, and the pink line is the trajectory. It can be seen that the target coming from the right can appear stably when it passes in front, although it is blocked by the target here. For the speed advantage mentioned just now, especially for the target parked next to it, if it is a detection frame, once the jitter is beyond the range of post-processing energy cover, there will be a relatively large speed, which will trigger a trajectory and cause some brakes of the car. Like here, parked next to it is very stable, and the speed is basically consistent with reality.

Real vehicle deployment and closed-loop verification

The last part introduces several key problems related to the model when the real vehicle is closed-loop.

First of all, the model must be quantified and compiled before deployment. Professional quantitative processes and methods, we also arranged an open class to share later. I mainly look at this matter from the perspective of a user.

For the general model, such as CNN-based, we directly single-task float and directly train qat after training, which basically does not lose points. A freezebn will be added in the middle of multiple tasks, so that the counted bn can be applied to each task.

For complex models, a step calibration will be added. The key point here is calibration. Take our end-to-end model deployment as an example. As far as the single-task model is concerned, there are many drop points in the early end-to-end direct float training qat. After consulting my colleagues in the tool chain, I suggest that we do calibration. However, after calibration, it is found that although qat has been greatly improved, it still has a big gap with float. Colleagues in the tool chain suggest fixing the scale of weight or feature. Actually, it is more effective to fix the scale of the feature, but it does not completely solve the problem of qat output of the above tasks from end to end.

So what’s the problem? I also went to some pits. In fact, it is very simple to think about it now. We need to calculate the appropriate feature scale and select the appropriate data when doing calibration. For example, in the early stage, we used the data of urban scenes to estimate the feature scale of speed, and found that the qat index of the trained qat model in high-speed scenes was worse than that of the float. Later, through the tools of the tool chain, the model was analyzed layer by layer and it was found that the problems on the model could not be found. If there is nothing wrong with the model, it is a problem with the data. Finally, we use a high-speed data set. Because calibration itself has few training steps, it is necessary to select the quantity that can cover the perception and reach the upper and lower limits of the maximum and minimum values, so as to estimate a more suitable quantitative scale.

Despite this step, the problem of quantification has been greatly solved. However, the standard of tool chain is generally that the gap between qat and float cannot be greater than 1%. After these two steps, it still can’t reach this level. So what else went wrong? Later, it was also a groping, and it was found that many quantities of 3D perception on BEV were physically meaningful. The final conclusion is to fix the scale for some physical computing layers. Where does the fixed scale come from? For example, as mentioned earlier, the feature on the query index BEV has warping operation, and it has clear physical significance to calculate the two inputs of offset. When the model structure is determined, the maximum and minimum values of the meshgrid on BEV, as well as the maximum and minimum values of the query index, have been determined, so that the maximum and minimum values of the matrix can be calculated, and then the fixed scale can be calculated.

For example, taking odometry as the model input, the data of calibration may be collected at a medium speed, but the speed of the self-propelled vehicle may also change during the actual large-scale data training. Therefore, the maximum and minimum values can also be obtained for this physical quantity with clear rules. With a similar idea, check some numerical calculation layers with physical significance in the network and calculate the fixed scale. Through these operations, the qat problem of the end-to-end model is solved, and it is also a lot of experience. Let’s share it with you.

Quantization is compilation. Compilation means that the compiler directly converts the intermediate format hbir from qat, and finally gets the hbm format deployed on the real board. The specific details are also shared and introduced later. Here is mainly about the performance of BEV perception in actual deployment.

The large-scale BEV is the perception range of 100 forward, 30 backward and 50 left and right respectively, and the small-scale BEV is the perception range of 20 forward and 10 meters in the other three directions, so as to do the element perception on BEV. On the single core of Journey 5, such as a small parking area, the multi-task model of single core and single frame can reach more than 70fps; The wide range of driving can also reach more than 30fps. Even with end-to-end, the model directly output to trajectory prediction can reach more than 20fps, which is in the case of single core. There are two cores on Journey 5, and the frame rate can be further improved in model scheduling.

At the time of deployment, the generalization of the model is tested. Because the model of the customer’s car is different, the corresponding camera installation position and orientation may be different. Our BEV model, especially in the prototype development stage, has many customers who have been verified in the early stage, so a model can support the deployment of multiple models as much as possible, which requires a high generalization of the model. We have also explored a lot, and finally found that the four-plane spatial fusion method introduced earlier has laid a good foundation at the beginning. The example given here is that the training data are all collected by SUV, and the data of cars are used for evaluation. If it is a single plane, it has more than seven drop points compared with four planes.

On the basis of better generalization of the four planes, we will develop some enhancement strategies for training. There are two effective methods here: one is that the BEV model disturbs the image by the camera rpy in one stage, simulates the bumps in the process of vehicle driving, and enhances the image; In addition, it is assumed that the plane is in the place where the angle of view is converted, and then the plane enhancement is made on the plane where the camera leaves VCS, which is also assumed to be the disturbance of rpy.

With these two disturbance strategies, this performance (AP 72.60) can be achieved in the training and training of SUV models and measured in the car data set, which is similar to the performance of an adaptive car model that we have trained with nearly 1 million data collected in about 20 days. Therefore, these strategic feature ensure the generalization of our current BEV perception model in actual deployment.

After deployment, the speed of closed-loop iteration of the model is tested. Especially in the verification stage of the previous prototype scheme, the demo closed-loop verification of different real vehicle installation and deployment is supported through a total version. For the BEV training framework, any camera configuration can be supported. For example, 11v/9v/7v, 7v may replace the 4v panoramic view with 4v fisheye, or any other multiple perspectives, all of which can participate in the model training. When deploying, compile according to the corresponding camera configuration, and then you can do the corresponding test.

The other is the training speed of the model, especially after the time series fusion. Without optimization, if a single frame is trained for 5 days and 10 frames are linear, it will bring 10 times the training time, which is definitely unacceptable. We definitely need to do optimization, and some students who have developed the framework specially guide us to do optimization. At present, the training speed has increased by 56% after optimization.

Specifically, at present, the multi-task release, multi-task with more than a dozen task heads, and the end-to-end training of time sequence can be completed within one week. The later evaluation or the case CICD of some historical data are all automated, thus ensuring the efficiency of the training and distribution step.

Another important factor, especially in the early stage of real vehicle testing, will feed back some non-working case-bad case data. How to use these data in training? There are generally two kinds of optimization for Badcase: one is to mine from the collected data, which is more conventional; The other is to be able to use the returned Badcase data directly.

For things like 2D perception, the link we did in mass production before was relatively mature. For BEV perception, the difference is to see how the model of the brush library comes from or how the data sent to the target comes from. For dynamics, a pure visual large model is used, which is not limited by on-board op and computational power. We have a big model team, and the pure visual BEV big model specially developed has also been used in the dynamic Badcase processing link to generate a pseudo GT to participate in the training. Static, a purely visual mapping scheme, can also send the base map to the standard, and has been deployed to the static perception Badcase link on BEV. In fact, after the deployment of the model, many of them are infrastructure problems. At present, the infrastructure of horizon’s perception of BEV is basically mature.

That’s all I shared today, mainly to convey a few meanings. First of all, based on the fact that Journey 5 can do many things, we have also done many things on it. For the BEV sensing scheme, we can see that we have a better baseline for reference and iteration, so the conclusion is relatively solid.

In addition, if some online students are developing based on Journey 5, or are about to develop based on Journey 5, when you encounter quantitative problems, don’t give up too early. Besides considering the model structure, analyze the data from the perspective of physical meaning and give it a suitable scale.

Finally, I wish everyone a smooth development, and my sharing today is over. Thank you!
