This paper describes a system that reconstructs 3-D models of polyhedrons from three orthographic views represented by binary images. Our main stress is on the description of a new reconstruction algorithm. The pro-posed algorithm performs a combinatorial search based on the face decision strategy along with two heuristics. The constraint rules are developed on the basis of the properties of orthogonal projection geometry, which are dynamically applied to the combinatorial search process. Further, two heuristics are adopted in the combinatorial search process so that its way of interpretation follows that of human understanding. One is for ordering the search nodes to reduce the search space, and the other is for reconstructing the scenes as naturally as possible. The effectiveness of introducing heuristics is also proved and analyzed experimentally. It is shown that 3-D scenes can successfully be reconstructed by the proposed algorithms, and that the efficiency of the understanding system is improved considerably by the introduction of the heuristics.
