Motion curved surface analysis and composite for skill succession using RGBD camera

The skill succession method is almost oral. It is not quantitative but qualitative. Quantitative succession is difficult. In this research, after tracking of a subject's motion using RGBD camera, a subject's motion is visualized as the motion curved surface. Expert and beginner perform the sports and entertainment motion, and the character of the surface is analyzed. The character is the maximum curvature and surface area. In addition, we suggest the composite surface, because one RGBD camera is not all tracking motion by occluding the obstacle or subject' body parts. Finally, we confirm the validity of skill succession by watching skeleton motion movie and curved surface.
