Generally, a dynamic analysis of human motion has been performed under a condition that camera position and rotation are fixed and some markers are fitted on the body. Therefore, it is possible to calibrate the camera parameters in advance. Also, automated recognition of some human feature points such as the head, elbow or knees is possible. In order to understand a dynamic analysis of the most natural human motion, limitation of the camera and any marker on the body should be removed. For this ideal dynamic analysis, however, camera orientation parameters should be acquired in real time while recording a moving object. Furthermore, automated recognition of some human feature points should be performed.
The effectiveness of the video theodolite system for dynamic analysis of human motion has been indicated by the authors. This paper describes the dynamic analysis of human motion using sequential images which are taken by video theodolite. Also, image processing techniques are described.
