Experts develop intelligent ice sports training analysis system intelligent coach empowerment training

Zhongxin Online Hai, January 19 (Chen Jing, Hu Huizhong) reporters learned from Fudan University on the 19th that the intelligent ice sports training analysis system developed by Zhang Lihua, professor of the School of Engineering and Applied Technology and executive vice president of the Intelligent Robot Research Institute, allows "intelligent" coaches to empower the sports training of Winter Olympic athletes.

According to reports, the system uses artificial intelligence-based computer vision algorithms to intelligently analyze and compare skaters' movements, postures, speeds and other information, from qualitative, quantitative to customized analysis of the characteristics of each athlete, improve the level and efficiency of scientific training, effectively reduce the workload of coaches, and achieve scientific training, effectively improve the training effect of athletes and competition results.

The lack of professional coaching talents in winter sports has limited the enthusiasm and level of people's participation in sports to a certain extent. It is reported that previously, in order to better prepare for the 2022 Beijing Winter Olympics, the Ministry of Industry and Information Technology and the State General Administration of Sport began to plan and formulate an action plan for the development of the ice and snow equipment industry in 2019.

Professor Zhang Lihua has long been engaged in research related to artificial intelligence, computer vision and intelligent perception. On the crystal ice rink, figure skating athletes danced with beautiful melodies, and their posture was like a dragon, and in the athletes' dancing and rotating figures, he was keenly aware of the possibility of AI technology applications such as motion recognition and detection, motion analysis and tracking. Zhang Lihua proposed the use of artificial intelligence technology to improve the level of ice sports training. In February 2019, he led the team to cooperate with the Jilin Provincial Sports Bureau to start building a demonstration system for intelligent training in ice sports.

"We use artificial intelligence technology to analyze the skeleton of ice athletes, the movements of each joint, and the posture, which is called the identification and visualization of the skeleton nodes of the sports target." Zhang Lihua introduced. After nearly two years of efforts, Zhang Lihua's team has created an intelligent ice sports training analysis system, which can allow high-definition cameras to dynamically supervise athletes in real time on the sidelines, identify the key points of bones and sports trajectories on each athlete on the monitoring screen through sports target tracking and trajectory visualization, and display the statistical information of various sports indicators. "The trajectory and posture of short-track speed skating/speed skating are clear at a glance, from qualitative coach analysis to quantitative scientific analysis." Zhang Lihua said.

During the interview, the reporter learned that for figure skating, there are more evaluation standards, and the intelligent ice sports training analysis system can help athletes improve the specification and aesthetics of posture through three-dimensional skeleton node detection and posture estimation; the visualization of the 3D model of the sports target provides a convenient way for the technical analysis of the rotation count of figure skaters. It is reported that Professor Zhang Lihua has built a demonstration system at the Changchun Ice Training Base of the Jilin Provincial Sports Bureau.

In addition to ice sports, can this intelligent training analysis system also help other sports projects? During the interview, the reporter learned that the computer vision algorithm based on artificial intelligence can also monitor and analyze football players in real time, so that the "AI version of football" is no longer a dream. Zhang Lihua told reporters that in the future, his team will carry out competition training analysis algorithm and application system research for professional and mass sports projects, and according to the existing infrastructure construction of competitive sports competition training intelligent analysis platform, realize intelligent applications such as training auxiliary analysis and competition auxiliary refereeing, and build demonstration intelligent sports venues and intelligent demonstration facilities for mass sports, so that the general public can feel the new experience brought by "intelligent" services in daily sports.
