Autonavi Maps Wheelchair Navigation Upgraded to Break Barriers with Digital Power

Recently, the Autonavi map wheelchair navigation function has been upgraded, supporting the inquiry of subway in-app barrier-free bathroom information and subway in-app emergency call for help; in the walking navigation mode, it is possible to inquire about barrier-free bathroom information along the way. At present, nearly 2,200 barrier-free public toilets have been launched.

Users only need to turn on "Accessible Navigation" in the settings options on the Autonavi Map APP (My-Settings-Accessible Navigation-Open), and they can try to avoid steps, steep slopes and other road sections during the navigation process. At present, this function has covered 14 cities including Shanghai, Beijing and Hangzhou.

It is understood that this upgrade has also updated the information of barrier-free elevators such as overpasses. In the case of barrier-free navigation, it can be combined with barrier-free elevators, lifts, and other barrier-free facilities to plan the preferred route for users. Priority is given to planning subway routes during public travel, and users are guided to the entrance with a straight ladder.

In addition, users can freely feedback the information of barrier-free facilities around them, and together help to improve the barrier-free environment of society. In addition to the disabled, the elderly with limited mobility, parents pushing strollers, people who travel in temporary wheelchairs due to accidental injuries and people who travel with heavy objects can refer to the use of "barrier-free navigation" in different scenarios.

Being at home is too boring? Learn to have fun in parent-child interaction games.

  With the outbreak of the COVID-19 epidemic, the people of the whole country are united as one, and Qi Xin is united in fighting the epidemic. In this battle without smoke, in addition to the medical staff and related workers who went to the front line, ordinary people consciously isolated themselves at home, went out less and didn’t get together, trying to control the epidemic in a short time. Of course, in the days of anti-virus at home, from motionless to motionless, from motionless to motionless, people always feel that the outside world is really wonderful. And the children want to go out and have a close contact with nature.

  For this epidemic, I believe everyone has already understood that it is generally susceptible to the crowd, and the elderly and people with basic diseases are seriously ill after infection. For teenagers and children, from their physiological and anatomical characteristics and autoimmune function, respiratory tract infections are more likely to occur, and the younger they are, the less likely they are to be found. Once they get sick, they progress faster. Recently, the number of cases of children infected with novel coronavirus has gradually increased, and the smallest infected person is a baby less than 3 months old. Therefore, daily protection and observation at home are the key points to prevent infection among teenagers and children. However, it is children’s nature to move and play. In the face of this epidemic, exercise is also an effective means to improve immunity. On the contrary, sedentary will lead to decreased immune function and increased risk of infection. Although it is not suitable to go out, parents take their children to do some interesting little exercises at home, which can not only enhance immunity and prevent infection, but also release their children’s nature and get happiness in sports.

  Small body arithmetic, fitness and brain health.

  Use your body to express simple arithmetic with your child.

 

 

  Arithmetic 1: 1+1=2

  Action essentials: raise an arm to represent "1", the big arm is parallel to the ground, and the small arm is perpendicular to the big arm; The horizontal lifting of both hands forms a "+"with the trunk; Raise your hands horizontally in front of you for "="; Raising both hands at the same time means "2".

  Arithmetic 2: 2+2=4

  Action essentials: The number "4" can be represented by bending down, straightening your arms and touching the ground as far as possible. Your hands and feet form a "4", so be careful not to bend your knees during pressing. Parents can also let their children use their brains to find other body language that means "4".

  Arithmetic 3: 4+4=8

  Action essentials: The number "8" is represented by putting your hands on your hips and twisting your waist clockwise or counterclockwise, just like the "8" around a twist. Parents can also find more "8" expressions with children.

  Parents can take their children to continue to explore more physical arithmetic. After studying at their desks and watching TV, let them get up and do a set of such physical arithmetic together to avoid becoming couch potatoes. You can also disrupt the order and test each other with your children to see who can react faster and do more standard, and keep fit and strengthen your brain at the same time.

  Stop at the red light and go at the green light, and don’t forget to learn the rules for fitness.

  Preparation stage: everyone stays still and waits for the password.

  Red light: when you hear the red light command, stop moving immediately, keep your posture immediately, and wait for the next command.

  Green light: start jumping, jump with your hands and feet open, keep your arms straight, and clap your hands above your head; Jump again, feet together, arms straight down from both sides, hands touching both sides of thighs, and so on.

  Play traffic light games with children at home, and the rules are issued by giving a password that makes people shout red or green lights. When the red light is red, everyone stays still, and when the green light is green, everyone immediately starts jumping together. Participants in the game should give the fastest response according to the password, and the slowest response or the opposite response to the password is a challenge failure.

  People can increase the difficulty and interest of the game by repeating instructions and adjusting the interval between instructions. The jumping time of the green light should not exceed one minute, and it can be marked by the child’s accelerated breathing and slight sweating. The traffic light game can help children learn rules in the game and improve their reaction ability. At the same time, the opening and closing jump in the green light can also improve their cardiopulmonary endurance.

  Bear crawling, crab crawling, imitating animals is more fun.

  Although it is impossible to go out at home, parents can take their children at home to imitate the small animals in nature and crawl freely at home.

  Bear crawling: imitate the bear crawling forward, backward, left and right with his hands and feet. During crawling, try not to touch the ground with his knees and keep his trunk parallel to the ground as much as possible. Parents can also deliberately raise the trunk to let the children get out from below to improve the fun.

  Crab crawling: imitating crab crawling, parents lead children to support their trunk with their hands and feet in a supine posture, lift their hips off the ground, crawl left and right with their hands and feet, and touch the ground with their hips is a challenge failure. In the process of crawling, children’s coordination can be improved and their core control ability can be exercised.

  The above small sports and games are suitable for home, and at the same time, children’s immunity, sensitivity, coordination, cardiopulmonary endurance and other physical qualities and functions can be improved through exercise. The recommended amount of physical activity for teenagers and children is not less than 60 minutes of moderate and high-intensity physical activity every day. Parents can take their children to practice for many times, and each time they do a small exercise of 20-30 minutes. The intensity of exercise is appropriate for children to sweat slightly, breathe faster but still have a short conversation. Although children are longing for the outside world, playing some small fitness games with parent-child interaction at home in special periods can also exercise, enlighten wisdom, enhance parent-child feelings and have a pleasant and unforgettable holiday.

  Haikou, August 16 (Reporter Hong Jianpeng) China Telecom, China Mobile and China Unicom launched the sale of 5G mobile phones and 5G network experience activities in Hainan on the 16th. According to incomplete statistics, the three telecom operators have built nearly 200 5G base stations in 19 cities and counties in Hainan, and are still pushing forward the related construction work.

  On the morning of the same day, in a China telecom business hall in Haikou, Wang Jianhai, a citizen who bought a 5G mobile phone, became the first telecom 5G experience user in Hainan. He said that he has been waiting for a 5G mobile phone for at least half a year. Compared with 4G, 5G has greatly improved on the Internet and will have a good experience in watching movies and playing games. "Whenever something new comes out, I want to be the first to try and experience."

  According to the information recently disclosed by the Hainan Provincial Development and Reform Commission, Hainan Telecom’s 5G demonstration network project has been steadily advanced. By the end of June this year, 24 5G base stations have been opened. On July 24th this year, China Telecom opened 5G base stations in Yongshu Reef and Yongxing Island.

More than 800 5G base stations will be built in Hainan Island this year; Hainan Unicom has completed the opening of 48 5G mobile network sites in 19 cities and counties in the province.

  Hainan Telecom and Hainan Mobile also provided 5G cloud VR, 5G cloud games, 5G HD video and other application experiences at the experience site, so that users can feel the wonders of 5G networks in the first time.

  Chen Jianyang, general manager of China Telecom Haikou Branch, said that in the near future, Telecom will speed up the construction of 5G experience zones in business halls of cities and counties in the province, and gradually open core business halls around the province to give customers a taste of 5G mobile phones and 5G networks.

  He introduced that in the later stage, the 5G package settings will be optimized according to the characteristics of 5G, and the package traffic will be more. In terms of enhancing users’ perception, China Telecom will make innovations in the combination of communication services and applications in the next step, which is more in line with users’ usage habits, taking into account users’ diverse needs and providing diverse and differentiated services.

  Zhang Hehai, deputy general manager of Hainan Mobile, said that 5G is not a simple "4G plus 1G", it will provide infrastructure for cross-domain, all-round and multi-level industrial deep integration, and fully release the amplification, superposition and multiplication of digital applications for economic and social development. Hainan Mobile will accelerate the development of 5G, help industrial upgrading and high-quality economic development, and provide people with more exciting and better information services.

  It is understood that at present, all three operators provide 100GB of 5G experience traffic packages for 5G experience users every month, which can be used until the end of September this year. After the 5G network is officially commercialized, the 5G service plan and package will be announced separately.

Today’s New Year’s Eve, why not "30"? It changed to "29 years old" after a difference of one or two seconds, and it came back three years later.

The Spring Festival is approaching Shencheng with a strong flavor.
Today’s New Year’s Eve, I believe everyone is looking forward to a big dinner tonight. We have habitually called New Year’s Eve "New Year’s Eve". However, have you noticed that there is no "New Year’s Eve" this year, only "Year 29"?
In fact, this is all because our lunar calendar is "too reasonable".
Where is the New Year’s Eve?
Shi Kun, director of the Network Science Department of the Exhibition and Education Center of the Shanghai Planetarium, said that the solar calendar is the most commonly used in our life. In fact, it is more precisely the Gregorian calendar, or Gregory calendar. For example, January 1st of New Year’s Day, May 1st of Labor Day, October 1st of National Day, etc., all these festivals use the Gregorian calendar. The Gregorian calendar refers to the period of revolution-Tropic Year of the Earth, with an average of 365.2422 days a year.
The lunar calendar, on the other hand, is a combined calendar of yin and yang, and its month length is determined with reference to the apparent movement of the moon-the cycle of phase change. The moon’s cycle of "rain or shine" is called the new moon, the new moon is the new moon and the full moon is the hope, hence the name. The average length of a first lunar month is 29.5306 days (29 days, 12 hours and 44 minutes). Therefore, the number of days in the lunar month is either 30 days or 29 days, so there is a folk saying that "the big month is 30 days and the small month is 29 days". However, the arrangement of the big moon and the small moon is not arranged at regular intervals, but is completely decided by the moon phase.
We often say that "the lunar calendar is a traditional calendar in China with a history of thousands of years", but this statement is not accurate. Chinese culture has a long history, and there have been more than 100 calendars in thousands of years. The lunar calendar is only the calendar currently used, but it inherits the ancient calendars such as the summer calendar in terms of big principles and algorithms. The compilation of the lunar calendar stipulates that the first day of each month, that is, the "first day", is determined by the time when the "new moon" appears. This principle is called "the method of determining the new moon".
Accord to that compilation and promulgation of the lunar calendar drafted by Purple Mountain observatory of Chinese academy of science, "Shuori is the first lunar day of the lunar month", that is to say, the first day of each lunar month is Shuori. From "New Moon" to "Hope" and then to the next "New Moon", the period is about 29.53 days, so the calculated number of lunar months is either 29 days for a small moon or 30 days for a big moon.
Round counting, the lunar month is divided into 30 days and 29 days according to the size. If the twelfth lunar month happens to meet the lunar abortion, there will be no "New Year’s Eve".
Specifically, because it coincides with the 29-day abortion, the "New Year’s Eve" on the day before the Spring Festival of the Year of the Tiger in the upcoming lunar calendar has been "omitted".
There will be no "New Year’s Eve" in the next five years.
In fact, there are many times when the twelfth lunar month meets the abortion, and it is not uncommon for the twelfth lunar month to meet the abortion. There is no "New Year’s Eve" in the past 2013, 2016, and the next five years from 2025 to 2029.
Are there any rules?
"It is generally regular, but it seems that the regularity is not very strong locally." Shi Kun explained that it was because the moon, a satellite, was not small compared with the earth around which it revolved, so the orbit of the moon was not simple. It kept swinging, as if it were dancing a very complicated "waltz" between the earth and the moon. A lunar cycle averages 29.5306 days, but it is only average, which does not mean that every month is 29.5306 days. Similarly, the length of a lunar year may be 354 days or 355 days, which is not fixed (the probability of 354 days is higher).
If you don’t understand, imagine the extreme situation: if the new moon occurs at 23: 59, the number of days in the lunar month will be one day less; If the new moon happens at 0: 01, there will be an extra day. It is no exaggeration to say that a difference of one or two minutes can determine whether New Year’s Eve is "30" or "29".
The lunar calendar is so "reasonable", let nature decide everything!

Canal meijinghua shiplock

  Whenever people mention the Beijing-Hangzhou Grand Canal, they can’t help but call it "beautiful". In fact, the beautiful Beijing-Hangzhou Grand Canal, apart from its antiquity and civilization, has a unique flavor for its shiplocks. Especially in the northern Jiangsu Canal, it can be said that there are ten locks and ten landscapes. They are like ten bright pearls embedded in the 404-kilometer Grand Canal, and the ancient Grand Canal is decorated with beautiful scenery, which is particularly enchanting. In the 1980s, as a member of maintaining social order in the northern Jiangsu section of the Beijing-Hangzhou Grand Canal, I fought, patrolled, lived on the Grand Canal, and had zero contact with ten shiplocks along the way, and fully felt their unique scenery, mood and taste.

  In the spring of 1980, after I retired from the army, I was assigned to the Shao Bo Police Station of Jiangsu Canal Public Security Bureau (No.8 Gangkou Road, Huaiyin City). The police station is located on the bank of Shao Bo Lake in the lower reaches of Hongze Lake with beautiful scenery. Together with Shaobo Ship Lock, it hides in a thick cedar and tall unlined upper garment forest. If it weren’t for the loud "cry" of ships coming and going, it would be a paradise. The police station and the lock management office are located in a small courtyard next to the lock, surrounded by a circle of antique glazed tile walls, fan-shaped wall holes and a small round door, which wraps three rows of bungalows (two rows are the rooms for the lock management office and one row is the place for the police station). Since then, I have camped in the police station and stayed with Shaobo Ship Lock day and night.

  Shaobo Ship Lock was first built in 1934. Although the old lock has been scrapped, there is still an old lock wall standing along the river on the east bank of the canal. On this site, there is the autograph of "Jiang Zhongzheng", with three Chinese characters one meter square, embedded in the canal bank with cast iron, which fully shows how much attention the Kuomintang government paid to the development of canal transportation and water conservancy. Later, the ship lock was built in 1962. The lock chamber made of reinforced concrete and four watchtowers, like "Four donkey kong", stood on the Grand Canal. Because I was single, I had to take Zhajia as my home and guard the Subei Canal with the "Four donkey kong".

  The scenery of the ship lock in those days was unique and charming. In the early morning, I can stroll by the Shao Bo Lake near the gate and feel the beautiful scenery of the lake overlooking the lake, with vast smoke waves and little fish sails; Walking up and down the lock, smelling the passing ships burning small stoves and making breakfast, the smoke and rice fragrance floating out are refreshing and appetizing. In addition to its architectural beauty, scenic beauty and greening beauty, the ship lock also has the unique beauty in the lock room, which is constantly presented to me.

  The first is the beauty of "fishing for money".

  Unlike now, toll collectors on the gates are all in remote dispatching stations or central command rooms, using computers to complete the tasks of registering and charging passing ships. At that time, the toll collectors on the gates were all beautiful women with special skills. Each of them carried a ballot box, held a wallet and put a long rope (cotton) on their wrists. After calculating the cost of crossing the gates according to the number and tonnage of ships crossing the gates, they tore off the quota invoice and clamped it with iron clips. With the waving of their arms, the long rope flew out of a dazzling arc and landed on the docked bow accurately. The boatmen are always happy to accept invoices, change into banknotes, and then throw them at the toll collectors with iron clips. The beauty toll collectors pulled hard by inertia, and the long rope crossed a beautiful arc in the air and fell into their arms.

  The second is the beauty of releasing water.

  The water level difference between the upstream and downstream of a ship lock is usually several meters or more than ten meters. When the ship enters and exits, it must pass through the gate entry, gate closing and water release from downstream to upstream, and then open the gate and leave the gate after the water level is equal to that of the upstream. The release of water from the lock chamber is a scene of the lock. When the lock workers turn on the hoist (the button was manually operated in those days, but now it is controlled by the computer), the river in the upper reaches is like a runaway wild horse, rushing out from the lock wall, and the big waves, the noise and the water mist constitute a symphony of the lock. Under the refraction of sunlight, water mist can sometimes form a seven-color rainbow over the ship lock, which is beautiful and dreamlike. And I often worry about the safety of the ship in the lock room under this beautiful scenery. In fact, there is no need to worry. Before the fleet entered the lock, the broadcast on the watchtower reminded: "Attention, comrades of the crew, the lock is about to release water. Please put on your life jacket, fasten the cable and take the bamboo pick. Pay attention to safety. " The beauty announcer of the ship lock, the gentle and drizzling reminder, made the passing crew full of enjoyment in their vigilance.

  The third is the beauty of rock climbing.

  In those days, you had to climb the approach pier of the ship lock and hand in the navigation book to the gate workers before registering for crossing the gate. After entering the lock, you have to climb the lock surface along the lock wall and take away the navigation book. When the ship lock is in low water, it is thirty or fifty meters away from the lock surface. When the crew members walk on the Grand Canal all the year round, they will inevitably climb up and down at the lock. In the long run, they will all practice a unique skill of "rock climbing". Whenever the lock releases water, you can always see many crew members climbing. The simple costume, the vigorous figure, the bronze skin and the protruding muscles, like geckos, walk up and down the lock, vividly showing a "rock climbing map" of the lock.

  The fourth is the beauty of lookout.

  There are four watchtowers at the four corners of the lock. The one in the southeast is the command tower, also called the dispatching tower. Climbing to the top of the tower, the surrounding scenery is unobstructed. Looking to the west is the rippling Shaobo Lake, and the derricks of Subei Oilfield are dotted in the distance. Looking eastward, the ancient town of Shao Bo is near by the river, and the big docks, Dawang Temple and Shiban Street where Emperor Yangdi and Qianlong set foot in ancient times can be vividly seen. Looking to the south, the Grand Canal suddenly widened, connecting with Shaobo Lake, and flowing to the ancient city of Yangzhou against the backdrop of the slate of the east bank canal levee. Looking to the north, the Grand Canal floats from the north like a silver ribbon, and flows to the ancient town of Shao Bo in the guise of green trees on the west bank canal levee.

  The above four beauties can be said to be the common beauty of Subei Canal and ten shiplocks. Of course, apart from the similarities, there are also many characteristics that show the beauty of individuality. As for the difference of beautiful scenery, it should be that ten shiplocks are different. For example, Shiqiao Ship Lock in Yangzhou is famous for its royal garden style. Its rockery pavilion, small bridges and flowing water echo the ship lock architecture, and its pines, cypresses and winding paths add color to Shiqiao Ship Lock. In the last century, she was included in Yangzhou, an important place to receive foreign guests. I also served as the security guard for delegations from Romania, Albania and North Korea under the arrangement of the police station.

  Our Huai ‘an Ship Lock is famous for its water conservancy hub, and the water interchange upstream of the ship lock is the only one in China. Huai ‘an Fanshui Station is an important project of North-to-South Water Transfer Project, which has made great contributions to continuously transporting Yangtze River water to Beijing, Tianjin, Hebei and Shandong. The Siyang Shiplock in Suqian is famous for being located in an orchard. The fragrance of fruits, cherries in spring, peaches in summer and apples in autumn make the past crew linger. The Zaohe Shiplock in Suqian is surrounded by luoma lake on the left and Zaohe Ancient Town on the right. The history that Qianlong stayed in Zaohe Palace for many times added a heavy stroke to the classical beauty of Zaohe Shiplock. The Jietai Shiplock in Xuzhou is full of flowers and trees. Entering a ship lock is like stepping into a world of flowers, a green ocean.

  This is the canal lock that I remembered more than 30 years ago. Nowadays, many of the ten shiplocks have built three-line shiplocks and double-line shiplocks. Our two shiplocks in Huai ‘an are all three-line shiplocks, and they are the first shiplocks to realize modern management, ranking first in scientific management in China, especially in remote control, which has reached the world-class level. As the heart of ship lock command — — The Subei Navigation Management Office of Jiangsu Provincial Communications Department of Beijing-Hangzhou Canal is located on Yan ‘an East Road in the urban area, which plays an important role in the urban and economic development of Huai ‘an. Although Shidao Shiplock is not what it used to be, its aura is still there, and its scenery is more beautiful.

The sprint bike in the "hardest hit area", the top ten stimulant in sports, is the most typical.

  Tencent Sports News Recently, Wang Hongni, a famous triathlete in China, was found to have used illegal drugs and was banned for two years. The triathlete, which is considered as a "pile of medicine cans", was once again pushed to the forefront of public opinion. Looking at all kinds of sports in sports, ten sports are the "hardest hit areas" for doping. Although the anti-doping organizations keep conducting targeted inspections, they are still banned repeatedly!


  short-distance run


  Doping is the best way to improve the athletes’ instantaneous physiological function, so in the sprint events that need explosive power most, doping incidents are repeatedly banned, and many of those big stars who are suddenly in the clouds are later laid on the altar. The most typical example is that at the Seoul Olympic Games in 1988, Ben Johnson won the men’s 100m gold medal in 9.79 seconds and broke the world record. However, in the subsequent urine test, Ben Johnson was found to have taken synthetic steroids. In addition, gatling and Montgomery, two men who had challenged the world record, were also banned for two years. Jones, a famous American sprinter after Cojna, was also banned for taking steroids and returned to the Olympic gold medal. Ironically, Cojna, the greatest athlete in the history of women’s sprint, was also suspected of using stimulants and leading to her early death, so she still could not bury her body after her death, but had to undergo an autopsy to get her innocence back!


  Tour de France:


  Whether the Tour de France will survive or not is a hot topic in the sports field some time ago, because this dirty sport is challenging the purity of sports. International Olympic Committee President Rogge said that bicycles will not be excluded from the Olympic Games for the time being, which is already lenient. Armstrong, an American legendary hero known as "Forrest Gump" in reality and winner of the seven-time Tour de France, has created countless glories in his sports career, and his story of overcoming cancer and reaching the peak has inspired countless people today. But less than a year after his retirement, it broke the news that he had taken stimulants many times in the competition. For a time, the controversy about whether Armstrong was a lonely hero or a drug champion spread all over the world. Landis and ulrich were even worse than Armstrong. They were banned and deprived of the greatest honor they had ever won. In particular, Landis, an American, keeps going to court to prove his innocence, but it is useless for him to keep his mouth shut in the face of scientific evidence.


  strong and handsome


  Although this event is not an Olympic event, it has become a frequent doping event because of its good promotion in various countries, great visual impact and more commercial intervention. Bodybuilders need to stimulate their muscles, so some athletes should often take some so-called tonics to make their muscles develop. According to the statistics of the Anti-Doping Committee of the Chinese Olympic Committee for many years, the number of times bodybuilders tested positive for drugs is among the top three every year. Just this year, the decision on punishing bodybuilder Jiang Xi for violating the prohibition of doping was issued, and Jiang Xi was suspended from participating in national bodybuilding activities for two years from July 21, 2006 to July 20, 2008.


  There are many incidents of taking medicine in swimming, and many famous big-name stars are not immune from negative rumors. The most typical example is the Australian flying fish "Thorpe storm", which was first stirred up by the French newspaper L ‘Equipe. The newspaper L ‘Equipe reported that a doping test in May last year showed that Thorpe’s testosterone and luteinizing hormone obviously exceeded the standard, and these hormones acted like steroids, which could obviously improve athletes’ performance. Thorpe denied this, and was obviously greatly stimulated, so that at the press conference, what people saw was not the torpedoes in the past, but more like a sad and helpless child. It was not until this year that the Australian Olympic Committee cleared Thorpe. China women’s swimming team was also troubled by doping. In 1994, the glory of the World Swimming Championships was attacked by some foreign media for taking banned drugs. In 2000, Wu Yanyan, a famous Chinese athlete, tested positive for drugs and was banned for four years, missing the Olympic Games.


  weightlifting


  There are countless doping incidents in weightlifting, and a large number of lesser-known athletes are banned every year. Of course, well-known athletes often try their own laws. Mutlu of Turkey was once called a "weightlifting prodigy". At the Atlanta Olympic Games in 1996, Mutlu, 23, set a new world snatch record and easily won his first Olympic gold medal with an advantage of 7.5 kilograms ahead of the second place. At the Sydney Olympic Games in 2000, Mutlu, a "pocket strongman", was in full swing, not only easily defending his title, but also breaking three world records in snatch, clean and jerk and total score. At the 2004 Athens Olympic Games, Mutlu, 31, became a weightlifter who won three consecutive Olympic titles. However, in the 2005 European Championship, Mutlu was found to have used Nuolong and was banned, which also cast a shadow over the veteran’s declining state to participate in the Beijing Olympic Games.


  wrestling


  Wrestling emphasizes the use of strength and physical contact, so doping incidents are also common in this project. Domestically, Gao Yanzhi, a wrestler from Shandong Province, was suspended for two years for taking a diuretic, a prohibited drug, after testing in Athens Olympic Games. The foreign example is even more shocking. American male wrestler Benoit killed his wife and son because he took too many steroids! This steroid can strengthen muscles after taking it, but it can also cause emotional outbursts such as paranoia, depression and steroid rage. Therefore, the police said that they thought that Benoit was taking stimulants, which led to the whole person’s emotional loss of control and eventually violence.


  triathlon


  From the name "triathlon", it is not difficult to see the fierce competition. Only "iron man" can laugh at the end, and doping is undoubtedly the best tool to turn "man" into "iron man". On July 1st, 2005, the Swiss Olympic Committee announced that McMahon, a Swiss female triathlete and winner of the 2000 Sydney Olympic Games, had been found to have used the illegal drug EPO. McMahon admitted that she had taken stimulants, but she argued that it was because she needed stimulants to treat her illness, not to improve her athletic performance. Wang Hongni, the champion of the Asian Games in China, was declared unqualified by the triathlon official website on October 9th, which made the list of doping in this event filled with the names of China people.


  shot


  As a strength-oriented throwing event, many athletes in the shot put competition use illegal drugs at risk. During the Athens Olympic Games, Yong Quest, chairman of the International Olympic Committee Medical Committee, revealed in Athens that Russian player Korzalenko, who won the women’s shot put championship in this Olympic Games, failed the doping test! Korzalenko was deprived of his gold medal in the indoor track and field championships in 1999 because of doping. This is the second time he has committed a crime against the wind. Hunter, the husband of American female sprinter Jones, was found to have taken banned drugs such as steroids after the 1999 World Championships, and then he was banned from the IAAF for two years, so he missed the Sydney Olympic Games in 2000.


  Rugby


  Known as the most antagonistic sports football doping scandal in the world, Ha Silei, a retired American professional football player, revealed that according to his estimation, at least half of the players in the league were taking steroids before drug testing began in the late 1980s. He said, "If you don’t eat, you can’t be as strong as others and can’t keep up with their speed. This is the only reason why we take medicine, because the competition is too fierce. I was still taking steroids six weeks before I decided to end my career. " Keith Jones, an NBA Rockets trainer, said in a recent interview that during his years as a trainer, he saw too many football players taking steroid stimulants.


  Tennis:


  It is reasonable to say that the effect of doping in tennis, which emphasizes the change of skills and lines, will not be too great. However, with the prevalence of strength-playing, there are also many drug users in tennis. Poorta and canas have unfortunately become "leaders" in their respective fields. In addition, this list also includes Bulgarian beautiful girl Karatancheva. Nowadays, the names of Poorta and Karatancheva are rarely mentioned again, but canas has made a high-profile comeback after the suspension period, becoming one of the few players who have defeated Swiss ball king Federer in a row in recent years.

China smart car research selected for CVPR2023! A new method for 3D lane line detection, produced by Mimo Zhixing.

CVPR 2023, one of the top three computer vision conferences, was exposed in the paper of China Smart Car Company.

Domestic autonomous driving companyHao mo zhi hangThe paper Bev-Lane Det: A Simple and Effective 3D Lane Detection Baseline submitted by the technical team of its Artificial Intelligence Center was successfully selected into CVPR2023.

What problems should the new research solve?

3D lane detectionAs a hot topic in the field of automatic driving, it plays a vital role in vehicle routing. In the past, related technologies were often difficult to be applied because of its complex spatial transformation and inflexible representation of 3D lanes.

Faced with these problems, Millie independently developed an efficient and robust monocular 3D lane detection, referred to as:BEV-LaneDet.

In BEV-LaneDet, Millimeter team first converted all the internal and external parameters of the input image into unified internal and external parameters through the virtual camera, which ensured the consistency of the spatial relationship of the front cameras in different vehicles and effectively promoted the learning process.

Moreover, Millimeter Team uses feature extractor to extract the features of the front view image, and proposes a simple but effective 3D lane representation, which is called "Key-Points Representation". This module is more suitable for representing complex and diverse 3D lane structures.

On this basis, inspired by FPN, Millicent team also designed a lightweight and chip-friendly spatial transformation module called "Spatial Transformation Pyramid", which is a fast multi-scale spatial transformation module based on VPN, mainly responsible for the transformation from front view features to BEV features.

Finally, the team predicted the lane on the plane tangent to the local road surface, divided the local road surface into s1×s2 grids, predicted confidence, embedding for clustering, lateral error offset and the height of each grid, and used fast clustering method to fuse the results of each branch in reasoning to obtain 3D lanes.

How did BEV-LaneDet perform?

Through the above methods, the F1-S?core of BEV-LaneDet can reach 185FPS on the OpenLane dataset, which is 10.6% higher than the current SOTA.

BEV-LaneDet can also lead the current SOTA method by 4.0% in the performance of Apollo 3D Lane Synthetic.

At present, Mimo Zhixing is the first echelon player in domestic self-driving mass production, and the paper written by its technical team BEV-LaneDet was selected for CVPR, which is actually the embodiment of the technical strength behind the commercial progress.

At present, HPilot has iterated three generations of products, and has achieved mass production on nearly 20 models of Wei brand, tank, Haval, Euler, Great Wall Gun and other brands. In the future, passenger cars equipped with Millimeter-assisted driving products will reach millions of orders of magnitude. As of February 2023, the mileage of user-assisted driving has exceeded 35 million kilometers. NOH, the first city in China that can land on a large scale, has also reached the delivery status with its software sealed.

In addition, the terminal logistics automatic delivery vehicle has initially completed the commercial closed loop, delivering more than 1,000 units, and the delivery order volume of the terminal logistics automatic delivery vehicle Little Magic Camel series has also exceeded 160,000, and the commercialization process is accelerating in an all-round way.

Introduction to CVPR

IEEE (Institute of Electrical and Electronics Engineers) CVPR (Conference on Computer Vision and Pattern Recognition) is one of the three top conferences in the field of computer vision and pattern recognition.

The main content of the conference is computer vision and pattern recognition technology. CVPR is the world’s top computer vision conference (one of the three top conferences, the other two are ICCV and ECCV). In recent years, there are about 1,500 participants every year, and the number of papers collected is generally about 300.

CVPR has strict employment standards. According to CVPR officials, CVPR2023 received a total of 9,155 papers, a record high, and the organizing committee finally hired 2,360 papers, with an acceptance rate of 25.78%.

CVPR is also the witness of major changes in the field of AI vision. The current wave of AI driven by deep learning originated from Hinton’s blockbuster in CVPR Challenge.
