Abstract: 3D human pose estimation and tracking is a popular problem of machine vision. In order to improve the stability of human pose tracking, the human body motion posture is represented by the human joint DOF (Degree of Freedom) vector, the human pose is tracked by the unscented Kalman filter method, and a human pose tracking system based on double Kinect sensors is built. Compared with the traditional human motion capture system, the system can accurately and stably track 3D human pose under simple movements, reflect the special nature of the motion process under complex movements, and can be used in the performance evaluation of sports biomechanics.

Key words: 3D human pose tracking, Kinect sensor, human joint DOF, unscented Kalman filter, sports biomechanics
