Duplex camera portable motion capture system for single athlete’s performance analysis

In recent years, introduction of depth camera in motion capture have caught a massive attention by both researchers and biomechanists. Therefore, high-performance sports certainly require motion capture technology to compete with other competitors. Thus, a study involving quantitative analysis...

Thus, a study involving quantitative analysis is important to obtain a more accurate analysis. The purpose of this study is to develop duplex motion capture system for biomechanical analysis of sports. The visual sensor used in this research consists of two Kinect sensors Microsoft.
