力学モデルを用いた3次元モデルマッチング手法による宙返り運動の復元

抄録

This study presents details of the project that would estimate joint angles of human from captured images by using model matching method. While human subjects perform on a trampoline, the researcher converts the movement into information with a human inertia model. Performance is photographed by four high speed cameras. The posture of human subjects was determined by using model matching method. However, three dimensional model matching method has some weak points such that search range becomes huge. Accordingly, by solving an equation of free-flying system, the joint value of the following body movement is presumed using that of the present body movement. Finally, one forward somersault with half twist at layout position was reconstructed.
