Motion Analysis of Striking Sports by Synchronizing High Speed Camera and Video Camera

Abstract

A lot of research has been done on striking sports, many of which are burdensome to players because players have to be put markers on such as optical markers and accelerometers. Therefore, it is necessary to obtain useful data for feedback to players only using multi cameras. In this paper, we propose a method for motion capture and calculating the impact force using synchronized high-speed cameras and video cameras in golf. We performed the experiment with one subject, and it was found that it was possible to calculate the joint torque from the impact force to the wrists and evaluate the posture at the impact.
