Abstract :
This paper presents an opto-mechanical apparatus for binocular stereopsis based on the Helmholtz reciprocity principle. The proposed system makes it possible to obtain three-dimensional models of static and dynamic scenes with arbitrary reflectance properties including highly specular surfaces and holograms. We also propose an empirical methodology for the treatment of occlusions that improves the description of half-occluded areas. Experimental results with real images validate the proposed system.
