Paper Abstract

This paper present a stereo matching approach based on topological and geometrical cooperation. Our approach has double-aim in first to reduce the complexity of the matching and in second to obtain structured matching in order to allow the CAD modeling of the 3D scene. The propose of our work suggests to represent each view by famous tool used in geometric modeling and CAD domain called em combinatorial maps witch is one of(B-Rep) representation. According this principle, topological information structured by combinatorial maps are associated with the views. In addition, each map contain geometrical informations about the primitives to be matched. Matching consist then to use together a topological process that uses topological structure to propose matching and geometrical process to validate these matching or adjust the maps. At the end, the obtained matchings are directly structured by combinatorial map, which represent the model of the matched scene. By closing faces in this model, we find new matches. structure the scene at the beginning of the feature-matching process and the enables to improve the matching performance in order to make easy the modeling of the final 3D-scene
