Experiments with the intensity ratio depth sensor

Abstract This paper discusses a modification of the “plane-of-light” approach to range data acquisition which utilizes the ratio of two intensity images. The modification allows depth determination at each image pixel, avoiding the need to scan the plane of light, requiring only the acquisition and processing of two or three intensity images. The depth equation together with three experimental methods for its calculation are presented. Results of the three sensor implementations are given for test scenes.
