Development of a motion analysis system using acceleration sensors for tennis and its evaluations

摘要

The term biological motion is often used by researchers studying the patterns of movement generated by living forms and in sports. We studied a pattern recogni tion system of motion in sport using biological motion data. Biological motion data are acquired using a 3D motion capture system. However, 3D motion capture systems are very expensive. In this article, a biological motion capture system was built using acceleration sensors. Our proposed system uses the technique of Gaussian fitting and regression analysis. We tested our proposed system in pattern recogni tion of outdoor tennis and its evaluations.
