A three-dimensional range camera, which produces a range map of the distances from a reference to each of M.times.N points in a scene, is modified to generate registered luminance and range images. The same sensor detects range and luminance variations. A planar pattern projector generates sequential...http://www.google.de/patents/US4687326?utm_source=gb-gplus-sharePatent US4687326 - Integrated range and luminance camera
