Some range sensing methods using a single camera have been proposed. Most of them utilize eccentric apertures. In these techniques, the higher the resolution of the picture, the more accurate range sensing can be achieved. In order to obtain the high spatial resolution, a HDTV camera is employed in the present system. And three eccentric apertures, which form a right-angle triangle, is placed in front of the camera lens. As the results of the calibrating experiment, the system has shown a fairly good measuring precision of about 0.2% of the picturing distance. Adding to the precision, it is found the eccentric aperture realizes the faster analysis by offering easier pattern recognition.
