A mobile motion capture system employing image transfer

This paper proposes a technique for recovering 3-D shape of remote non-rigid objects employing mobile cameras. Since the proposed technique allows independent move of the employed cameras, 3-D recovery under various environments such as remote places can be realized. Our. technique has an advantage over others in that camera calibration before taking images is not prerequisite to the recovery. A system is described that captures images of remote objects by the proposed motion capture technique, transfers the images by analog airwaves, and recovers 3-D shape of the objects from the images. It is expected that this technique will improve the efficiency of image information transfer. In the performed experiment, a human walking motion captured at a remote place recovered its 3-D motion successfully at a laboratory by image transfer.
