3D measurement using stereo scene coding

This paper outlines the hardware and software developments that have resulted from the active stereo probe (ASP) project´s investigation into 3D surface recovery using structured pattern projection. Scene objects are illuminated by patterns projected by the ASP active illumination projection system (AIPS). Images of the patterns, disrupted by the scene, are then captured using the ASP stereo camera head and analysed using a technique called Stereo Scene Coding (SSC) to recover 3D information. Recent, post ASP work has concentrated on viewpoint integration to facilitate complete object modeling
