Analysis and Comparison of Motion Capture Systems for Human Walking

This paper compares two novel motion capture systems using several biomechanical measurements during walking operations under various conditions. The first one is CATRASYS (“Cassino tracking system”) that was initially used as motion capture system applied to Robotics since 1994 at the Cassino University. The second one is the commercial Kinect™ system, which consists of a depth sensor and specific software, and can detect and track human forms. This paper studies problems and experiences in using both measuring systems through a comparison of results obtained from their use. It also enables characterization of walking operations by means of a model based on the paths of the ankle and knee points.
