With a perfect arc ,31 Year old Xu Mengtao , wait for 12 year , Finally take down Winter Olympic gold medal ！

This arc can be described as the current women's air skills project High difficulty action , Coefficient up to 4.293.

Xumengtao also relies on skating AIDS 、 Take off 、 Turning in the air and landing at one go , Capture 108.61 The high score .

stirring , It's really exciting .

And just now , CCTV revealed that xumengtao had completed this “ Dream arc ” One of the killer maces behind ：

The world's first Participate in the whole training 、 The virtual coach who helped win the gold medal —— Guanjun .

CCTV also commented on this ：

It is a piece of The gold medal of science and technology .

thus , Many friends will certainly raise such questions ：

Guanjun , How to be competent as a virtual coach ？

For aerial athletes , Because the project has certain risks , So their daily training amount is limited .

therefore , In order to improve the efficiency of training , We need to strengthen our athletes Memory of high score actions .

What Guan Jun has to do , It is such a thing .

It was developed by Xiaobing company AI Referee and coach system , Internal code is Guanjun Xiaobing system  （Xiaoice-International Athletic Scoring System, X-IASS）.

What's more surprising is , From the disclosure ,“ Guanjun ” As non-human , I have been on the Freestyle Skiing Aerials team “ To see service ” 了 Three years .

Guan Jun will make professional judgment for each jump of the athlete , Strictly judge the action of score deduction .

And it is the kind that is highly consistent with the scoring standards of international referees .

More specifically , Guan Jun will be among the athletes Take off 、 In the air and to ground Three stages , Make one Quantification of whole process actions The job of .

For example, in the following training process , You can provide the speed and angle of movement in real time 、 How many meters has the highest point reached , There are landing points and other information .

And Guanjun can “ see ” It's not just these “ Some information ”, He can also analyze the whole set of movements of athletes in the air .

Does the athlete appear such as “ Bend your knees ”、“ Lean over ”、“ Split legs ” In this way Point deduction action , as well as Result score How much will it be , You will give them one by one .

With such data , Coaches can give athletes more accurate basis for guidance .

More Than This , Guanjun's system is not that kind of “ Disposable ” Of .

He will also create an exclusive sports file for each athlete , Used to trace the action details of each jump , Aggregate for long-term training , Assist in formulating scientific training plan .

As for why the national team dare to use such new technology , Because Guan Jun is a Tested AI——

As early as last year （2021 year ）2 In the Beijing Winter Olympics test competition held in September , Guan Jun is the director of the air technology project The only competition referee .

At that time, Guan Jun had already completed the individual pre-finals 、 Super finals 、 There are... In the team finals 44 The person in charge .

It also won the International Snow Federation 、 Winter Olympics Organizing Committee 、 Unanimously recognized by the winter sports center of the State General Administration of sports .

according to the understanding of , This is also AI It is the first time in the world to complete the task of judging the competition independently .

（ It has a unique flavor .）

Then the next question is , What does Guanjun rely on to achieve such accuracy ？

According to the introduction of Xiaobing company , Guan Jun relies on Xiaobing's computer vision and complete framework technology , Pioneered “ Small sample 、 Big task ” Snow and ice movement analysis model （Xiaoice CV Analysis Model for Winter Sports）, Provide real-time services for coaches and athletes 、 Professional judgment and guidance .

besides , Xiaobing also passed Small ice depth neural network rendering technology  （XNR）, Give Guan Jun the characteristics of virtual human , Including appearance 、 Voice and unique character .

So since , Guanjun has biological characteristics that are highly similar to human beings , More in line with and close to “ Virtual coach ” This role .

AI Enter competitive sports , Is it necessary ？

Last , When the virtual coach behind xumengtao's title was exposed , Another issue that needs to be discussed is ：

AI What can technology bring to competitive sports ？ Is it necessary ？

Answer that question , We might as well start with the pain points of traditional human coaches in the training process .

Or take the air skills project as an example , These problems often exist in real scenes ：

• High light and complex background

• Athletes have a very short stay in the air

• Competition site restrictions, etc
  

These problems can make the judgment of human coaches very difficult .

But Guan Jun is not affected by time 、 Site restrictions , Real time prediction based on Athletes' movement sequence , Make target detection 、 Target tracking and target recognition , And it's real-time .

In other words , Guan Jun is such a AI Referee and coach system , Compared with the traditional way , The biggest difference is Fully automated .

It doesn't depend on humans to operate these systems , Through the automatic process to achieve action collection , And carry out scoring and other work .

In this way , It can help more athletes and human coaches to improve their performance .

But in fact , such “AI+ sports ” The way , It has been going on for some time .

According to CCTV , since 2018 year Winter Olympics of science and technology Since the implementation of key projects , The winter sports center of the General Administration of sport of China has started a new practice of intelligent technology and sports , Make the training more scientific .

And from this winter Olympics , It's not hard to see. ,AI Technology is not just used in aerial skills projects , In many other ways .

Even A weather anchor who broadcasts the weather , All are AI Virtual human ：

you 're right , The weather is being broadcast with both voice and emotion , He is not really a person , But a very pure AI Virtual human —— Feng Xiaoshu .

And long before the Winter Olympics 10 God , He has been on various platforms “ Work with certificate ” 了 .

……

CCTV commented that the gold medal of xumengtao is “ Quite scientific and technological ”, But on a larger scale , This winter Olympics is still releasing a new signal ——

Competitive sports have entered AI Time , Moreover, it is still the stage of practical achievements .

Just like Xiaobing CEO Described by Li di ：

I'm glad that Guan Jun has the honor to contribute to winning the gold medal in the Winter Olympics , This is a new step for the sports industry to enter the era of artificial intelligence .

In sports , We plan to cover the majors from the arena AI The coach , To sports news anchor 、 The virtual staff of the venue 、 Campus sports assistant 、 Mass fitness coaches , Even sports brands AI The complete scene of the designer .

Maybe next , Athletes are no longer just competing for their own skills , Maybe we should also try our best to help AI Technology .

At the opening ceremony of the Beijing Winter Olympics ,Faster,Higher,Stronger,Together The new Olympic motto of has attracted much attention .

In terms of the appearance and assistance of Guanjun , This Together, It also points to man-machine symbiosis , Point to AI With the help of human beings, they are faster to limit and potential 、 Higher 、 Stronger exploration .
