Abstract
This paper describes a 3D motion capture system to generate a skeleton model representing the human body. The system consists of a number of digital cameras placed at arbitrary position around the subject. The subject's joints to be measured are attached with illuminated landmarks. The 3D dynamic information of these landmarks is then detected using the Direct Linear Transform (DLT) technique. In order to establish corresponding point of the landmarks across individual camera as required in the DLT procedure, the quad-tree searching scheme has been adopted which can speed up the dynamic 3D modelling process of up to 70 percent. The 3D motion capture system has been performed to visualize the motion of various subjects. The result is very promising © 2006 IEEE.
