The quadrennial Winter Olympics, because of the attention of people around the world, is also an arena for cutting-edge technology. From the efficient training of athletes, to the layout of the venue, the broadcast of the event, to the light display, the referee's fine motion score of the players, everywhere is the shadow of high technology.
The 2022 Beijing Winter Olympics has attracted high attention around the world with the help of these black technologies and mature short video self-media platforms. It is understood that even if due to time differences, in most European countries can not watch the Beijing Winter Olympics in real time, an average of half or 3/4 of the population watched the Beijing Winter Olympics through various forms, which shows its unprecedented influence.
However, under such a high degree of attention, how to perfectly present every detail of the athletes' actions in the event is not only a challenge to the event organizers, but also an opportunity to show the mainland's advanced technology at the national level. Among them, Baidu intelligent cloud is a very powerful technical support behind it. Moreover, Baidu's intelligent cloud's 3D+ AI technology also plays an extremely important role in key links such as the content presentation of spectators and the quantitative scoring of athletes' actions, so that technology can help ice and snow sports to be seen and touched.
Empowered by 3D+AI technology, the viewing is more intelligent
Regarding the application of 3D+ AI technology in the Winter Olympics, CCTV's "Infinite Mysteries" and "Hall of Honor" programs have introduced that during the Winter Olympics, Baidu Intelligent Cloud respectively in the "time and space freeze-frame", "quantitative analysis", "same field competition", "virtual reality" and other aspects, to empower the audience to watch the game, so that the presentation of the game content is more colorful.
It is so-called: a quarter of an hour on stage, ten years offstage. As we all know, the athletes at the Winter Olympics, all kinds of competition actions seem to be in one go, in fact, behind it is the sweat of athletes who study hard. Therefore, how to ensure the fairness, impartiality and openness of the rules of the game, as well as allowing the audience to understand the whole process of the game more intuitively and graphically, while allowing the referee to score the athletes easily and objectively, is the key to ensuring the success of the event.
The wisdom of Baidu Intelligent Cloud lies in the fact that it lowers the threshold for watching the game and transforms professional terminology into a visible picture. For example, its space-time freeze-motion technology freezes the continuous motion of the time series into 3D space, achieving a 360-degree view. It is understood that this technology is quite a 3D version of the "stroboscopic camera", which is characterized by capturing high-speed motion and presenting it to the audience in a 360-degree manner.
For example, as the responsibility of ice and snow traffic, Gu Ailing's every refined action is breathtaking. The time-space freeze-motion technology technology of Baidu Intelligent Cloud can truly restore every detail, so it can be used for the daily training of professional athletes and ice and snow enthusiasts, and can also allow ordinary audiences to more intuitively appreciate the charm of ice and snow projects. It is not difficult to see that the reason why the popularity of this Winter Olympics is not reduced is also related to these wonderful presentations.
It is understood that the advantage of this technology is that the duel between the masters can be distinguished between millimeters. The principle is that through the quantitative analysis of "3D + AI" technology, a series of motion data such as accurate gliding speed, lifting height, landing distance, rotation angle and so on can be superimposed with the original picture.
It is worth mentioning that this is not just a static picture superposition, but implemented on high-speed continuous action video, which was originally a very difficult industry problem to overcome, but was perfectly cracked by Baidu Intelligent Cloud.
In addition, Baidu Intelligent Cloud uses virtual reality technology to reconstruct and virtually restore the big jump platform in three dimensions, creating a 1-to-1 stadium 3D model of the Shougang big jump platform, and the audience can freely watch the big jump platform from multiple angles such as long-range, panoramic view, and close-up view through the form of 3D scene roaming, and can switch between different landscapes and visual effects.
This "virtual reality" technology makes watching the game more interesting and attractive. In addition, it can also achieve smooth and accurate quantitative analysis, so that the audience can watch the game more immersively, and it is easier to appreciate and understand the professional game.
You know, in the Winter Olympics, the most tangled and difficult to distinguish between victory and defeat is how to weigh between the champions and runners-up. For example, in a single-player scoring event such as the big jumping platform, it is difficult for ordinary viewers to see the difference between the top players, and even professional referees can hardly determine the winner or loser. The "3D+AI" technology of Baidu Intelligent Cloud solves the problem of high-speed and difficult action restoration, and realizes the three-dimensional recovery and virtual superposition of the first and second runner-up competition screens.
The audience can also more intuitively understand the technical decomposition of professional commentary, and easily understand the technical differences between players in terms of fluency, completion, difficulty, diversity and aesthetics. With the blessing of high technology, the champions and runners-up on the field are also immediately known.
With the help of 3D+AI technology, the training is more scientific
In fact, Baidu's intelligent cloud's 3D+ AI technology can not only make the audience's viewing experience better, but also make the athletes' training more scientific and efficient. As mentioned above, the "time-space freeze-motion" technology can be used for the daily training of professional athletes and ice and snow enthusiasts.
Through the standard capture of motion, capturing high-speed continuous motion and freezing into 3D space, not only can you see every action, coaches and athletes can also rotate 360 degrees to watch, front, side, back, top and other perspectives are fully covered. Its quantitative analysis technology can be used for professional athletes to review the competition and scientifically correct training.
Moreover, by watching back the video, the players can more intuitively understand the accuracy and completion of the action, find problems in time, correct and improve the details of the action in a more scientific way, and improve the training effect.
For example, in April 2021, Baidu Intelligent Cloud reached a cooperation with the Chinese diving team to create the first "3D +AI" diving auxiliary training system in China. Thanks to the fact that Baidu Intelligent Cloud captures thousands of frames of images per second through the integration technology of cloud, edge and terminal, and quickly processes various fine movements of athletes, it only takes 3 seconds at the fastest, and Baidu Intelligent Cloud also fundamentally solves the problem of diving data collection and analysis.
It is understood that this "AI coach" has been integrated into the daily training of the Chinese diving team, improving the training efficiency of athletes by 20%, and continuing to help the "Dream Team" win gold in international competitions.
In addition, Baidu Smart Cloud also provides a series of solutions for daily training in ice and snow sports. Improve your skills and achievements through quantitative analysis of movements and comprehensive scoring.
For example, Baidu Intelligent Cloud captures athlete training screens through Baidu Brain's 3D vision technology: through high-speed video intelligent collection equipment, each frame of training screens can be clear and without smearing, and can also be quickly sorted out and safely encrypted, so that training videos can be transmitted to the tablet in real time, which is convenient for coaches to guide athletes' postures and movements in the first time.
It is worth noting that Baidu Intelligent Cloud has also built an "encyclopedia dictionary" of ice and snow sports. The action code and difficulty coefficient in the system as a comparison reference, after each action completed by the athlete, a comprehensive intelligent score can be performed to help the athlete better quantify the horizontal and vertical comparison, the whole training cycle has become very efficient, and the level improvement of the athlete can also be directly quantified and perceived.
Increase the size of smart sports, Baidu intelligent cloud first
In fact, the technical application inside and outside the Winter Olympic games is only the tip of the iceberg of Baidu's intelligent cloud, and Baidu has long begun to lay out on smart sports solutions. Moreover, empowering sports tracks with the help of AI+3D technology is only one aspect. At present, the empowerment of its related technologies is to penetrate into the entire smart sports track, and there is a great momentum of forming an intelligent ecology in the industry.
It is understood that in addition to helping athletes train and empowering spectators to watch the game, Baidu Intelligent Cloud is also constantly innovating in content production. At present, its intelligent video production platform can realize the whole process of AI assistance such as disassembly, combination, cutting, editing, etc., intelligent collection analysis and abstract extraction of the whole process of movement, dynamically generate short video collection content, reduce labor costs, and improve overall creative efficiency.
It is worth mentioning that Baidu Intelligent Cloud is also actively exploring the field of sports + health management, through the "smart wearable + AI + big data" scientific and technological means, with real-time monitoring of sports load, exercise density and other data as the core, combining smart wearable devices with exercise teaching practices, and daily digital monitoring and management of health indicators.
It can be seen that on the track of smart sports, Baidu's intelligent cloud technology is everywhere, even omnipotent. It is foreseeable that with the help of Baidu Intelligent Cloud's AI+3D and other technical capabilities, the smart sports industry will also have great potential. The application of science and technology in the sports industry will gradually cover all aspects, from daily training to large and small competitions, will see the figure of "black technology".
epilogue
A flawless Winter Olympics has come to an end, but the hardcore of China's science and technology that has been demonstrated has long been deeply rooted in the hearts of the world. We have reason to believe that the science and technology represented by Baidu Intelligent Cloud will further accelerate the pace of development of global sports, so that science and technology is no longer a high-cold posture, but a human firework within people's reach.
Therefore, the empowerment of Baidu intelligent cloud 3D+AI in the Winter Olympic Games is not the starting point, let alone the end, but the future worth looking forward to in the smart sports track. Moreover, in the context of the era when cutting-edge technologies such as artificial intelligence are gradually applied to all walks of life, its penetration in sports tracks has also entered the deep water area. There is no doubt that Baidu is a pathfinder on this track, and it is also a leader.
