Abstract
A working prototype three-dimensional television display has been constructed and initial feasibility studies have been carried out. The system employs the time division technique which takes advantage of the interlace facility on the standard television display and incorporates electro-optic viewing spectacles for the observer. Improvements to the basic system have been carried out which include remotely triggered viewing spectacles, thus giving greater freedom of movement to the observer and also an increased switching rate to reduce the effects of flicker. It soon became apparent that a system containing an integral real time depth measurement facility would be attractive to potential users. The method used is the application of a photogrammetic technique to the display in order to provide a real time three dimensional viewing and depth measurement facility. Present available techniques involve processing a stereoscopic pair of photographs which introduces an obvious inherent time delay. For many applications a real time technique has advantages even though the depth resolution is unlikely to be as good as the standard photographic system.
