Outline of Final Research Achievements

A research was conducted to apply the markerless motion capture device Kinect to the filed of rehabilitation evaluation. Four Kinect devices were placed along the walkway. The skeleton positions detected by these Kinect devices were integrated and the human motion during 10 m walking was obtained. From the motion data, the step length and the walking speed were calculated. The depth images obtained with the Kinect infrared camera were processed to analyze the walking motion on a treadmill. The results were compared with those produced with the Kinect skeleton. Furthermore, a system for measuring the head motion during the Timed Up & Go Test was developed. The accuracy of the measured head positions was evaluated by comparing them with those obtained with a conventional 3 dimensional motion capture system.
