Measurement and Analysis of Golf Swing Based on Video Motion Capture

Abstract

We report the system for the measurement and analysis of the motion using video motion capture for the golf swing. In the proposed system, multiple RGB cameras are used to acquire shutter-synchronized images using trigger signals, and three-dimensional reconstruction of the body motion done by solving inverse kinematics using machine learning based pose estimation method. After the estimation of the muscle tension by inverse dynamics and measurement of the kinematic sequence of the swing, the developed system provides feedback to the subject of analysis results. The calculation results are well displayed in an intuitively comprehensible format.
