The need for capturing human body motions has been increasing recently for making movies, sports instruction systems and robots that can simulate human motions. The paper proposes a method to facilitate motion capturing using inexpensive video cameras. In our system, a few cameras are used to obtain multiple views of a human body and a three dimensional (3D) volume consistent with the views is created. A model of the human body is then fitted to the volume to obtain the configuration of the human body. We also propose a method to analyze the stability of human postures. We have analyzed a technique of the traditional Chinese martial art, Shorinji Kempo, based on stability to show the effectiveness of our method.
