Abstract: A three-dimensional image processing system which reconstructs real-time display images from scene photographs. The system permits real-time projection of multiple, digitized, photographic databases into the eye space of an unconstrained observer. From the photographic databases, the system forms a composite output image as well as line-of-sight range overlay which permits easy expansion into a multi-channel architecture and to provide line-of-sight range envelope around the observer. The system allows for arbitrary insertion of three-dimensional, independently moving, opaque or partially transparent objects.
