Understanding three-view drawings based on heuristics

A system that reconstructs 3D models from hand-drawn three-view drawings represented by binary images is described. The authors lay main stress on the description of a heuristics directed reconstruction algorithm. The proposed algorithm performs a combinatorial search based on the face decision strategy along with two heuristics aiming at simulating the human's understanding way of interpretation. One is for finding a good sequence of search nodes, and the other for finding more natural scenes earlier than unusual ones.<>
