Providing key parameters of athletes in real time, the CCTV live broadcast of the Thomas and Uber Cup uses Shanghai's large model technology for the first time

Release time:May 06, 2024 17:26 PM

During the May Day holiday, many people watched the CCTV live broadcast of the Thomas Cup and Uber Cup badminton matches. Have you noticed any difference between this live broadcast and the past? According to reports, the "Pudong" large-scale real-time analysis model of sports techniques and tactics developed by the Shanghai Artificial Intelligence Laboratory made its debut. Researchers combined the core capabilities of "Pudong" with the "CCTV Audio Media Large Model" to calculate badminton matches in real time. A series of key parameters allow viewers to have a deeper understanding of the athletes' technical and tactical levels during the live broadcast.

Shanghai Artificial Intelligence Laboratory is a new scientific research institution in the field of artificial intelligence in my country. It carries out strategic and original scientific research and research, aiming to break through important basic theories and key core technologies of artificial intelligence. Through strategic cooperation, this scientific research institution and China Central Radio and Television jointly developed the "CCTV Listening Media Large Model", allowing some media practitioners to complete their work while "chatting" with the large model. For example, if you input a video, the big model can create commentary and press releases, with a variety of styles to choose from; if you input a text, the big model can directly generate related videos, the quality of which can reach high-definition video standards and have storylines. and shot continuity.

"Pudong", which is connected to the "CCTV Listening Media Model", is the first large AI sports technical and tactical model in China. It can obtain and analyze key parameter information in real time based only on sports video images without the need for wearable devices. With this technological function, replays of key parameters of badminton players appeared in CCTV live broadcasts.

Several key parameters of Chen Yufei and Jacksfield

For example, in the quarter-finals of the Uber Cup on May 2, the live broadcast of the match between China's Chen Yufei and Denmark's Jacksfeld showed the key parameters of the two players, including the distance of movement and the maximum smash ball over the net. Data such as speed, maximum net crossing angle, number of player's take-off attacks, player's maximum take-off height, etc. The live broadcast also showed the offensive and defensive paths and badminton movement trajectories of the two players in multiple rounds.

The real-time analysis data provided by the "Pudong" large model shows that Jacksfield's moving distance, maximum speed of smashing the ball through the net, and number of offensive jumps are all ahead of Chen Yufei. Fortunately, Chen Yufei relied on her strong comprehensive ability to finally defeat her opponent 2:0 and win the first victory for the Chinese team in the quarter-finals.

By integrating the core technology of "Pudong" into the "CCTV Listening Media Large Model", scientific researchers will transmit the analysis results to the central broadcasting control system in real time, providing professional AI technical and tactical analysis for live broadcast viewers. In order to make the analysis results more authoritative and credible, the pre-training process of "Pudong" integrates a rich knowledge base of badminton experts and corpus resources of professional commentators from the main station, so as to achieve real-time and scientific analysis and interpretation of technical and tactical skills.

The Shanghai Artificial Intelligence Laboratory research team and the CCTV technical team jointly provided live broadcast support at the Thomas and Uber Cup.

According to the Shanghai Artificial Intelligence Laboratory, traditional competitive sports data collection often requires athletes to wear hardware equipment, which will affect their performance, so it is difficult to collect data in official competitions. To this end, the "Pudong" scientific research team has developed a large model technology based entirely on computer vision, data and computing power. Wearable hardware devices are no longer needed and the data collection process will not have a negative impact on the athletes' competitive level.

In order to meet the strong timeliness requirements of live broadcast, the scientific research team uses real-time three-dimensional reconstruction and virtual measurement methods to ensure the speed of picture reproduction; at the same time, it uses multi-person 3D motion capture algorithm and video frame interpolation and motion deblurring technology to ensure that athletes and accurate tracking of badminton.

"Pudong" can not only meet the time-sensitive needs of live sports competitions, but can also be used in sports training to help coaches and athletes formulate targeted ability plans and improve competitive levels. With the help of the technical and tactical analysis capabilities of this large model, coaches and athletes can "find out the cause and effect" after the game and carry out targeted reviews. They can also "target" during training and digitize the performance of themselves and their opponents. , Intelligent analysis provides scientific basis for technical and tactical research on physical distribution, offensive lines, etc. in subsequent training and competitions.
