A technique of motion capturing using digital video (DV) cameras was proposed to measure the time dependent changes of human posture. This system was consisted of several couples of the DV networking unit which transfer the image frames, the shape extractors and the reconstruction server. The result of applicated test in the manufacturing cell, included material handlings, machining center and some instruments, the targets which put on the working uniform were able to captured. The result of calibration measurement indicated the system has good ability of spatial recognition when a couple of unit has 20 degree and 400mm distance from target.
