| Abstract: | This paper presents a three dimensional kinematic measurement method of human gait and introduces a measurement system which is based on image processing and machine vision techniques. The process of kinematic measurement of human gait includes five steps: image acquisition, camera calibration, joint marker detection, 3D coordinate reconstruction of the marker centers in space, and computation and output of kinematic parameters and graphs. The experimental system shows that this method is cheap in its implementation cost and has better measurement accuracy. |
