3-D modeling of remote dynamic situations employing mobile stereocameras

摘要

We propose a technique for 3-D modeling of objects in remote dynamic situations employing mobile stereocameras. Since the proposed technique allows independent movement of the cameras employed, 3-D modeling under various environments, such as remote places, can be realized. Our technique has an advantage over others in that camera calibration is not prerequisite to the 3-D modeling before taking images. A 3-D modeling system is described that captures images of remote objects, transfers the images by analog airwaves, and recovers the 3-D shape of the object from the images. It is expected that this technique will improve the efficiency of image information transfer. In the experiment performed, a human walking in a remote place was modeled successfully in 3-D in a laboratory by image transfer.
