As a natural development of work concerning the measurement of depth or range in three-dimensional television displays a prototype robot vision system has been investigated. The system uses a structured lighting technique and newly developed photogrammetric algorithms. The system gives a realistic cycle time for the acquisition of a complete coordinated matrix of image points. The pitch of the matrix could be varied for coarse or fine resolution and a measurement window could be defined anywhere in the field of view of the stereoscopic camera.
