Support image training for sports

Abstract

We developed a low-effort and -time body motion analysis system utilizing home-use digital video camera. Inputting the movie of sports motion and performance data into the system, image processing and statistical processing were automatically carried out and the postures that improve performance were instantly displayed. We believe that this system is useful for players to improve motion with image training because posture information that affects the performance is displayed instantly and visually. We present a newly developed system of motion analysis using tennis serve of a University tennis player as an example. As a result, the subject continued his serve practice with image training using this system and improved his performance of serve control.
