Abstract

It is an important problem for computer vision to match the stereo image pair. Only the problems of stereo matching are solved, the accurate location or measurement of object can be realized. In this paper, an integrated stereo matching approach is presented. Unlike most stereo matching approach, it integrates area-based and feature-based primitives. This allows it to take advantages of the unique attributes of each of these techniques. The feature-based process is used to match the image feature. It can provide a more precise sparse disparity map and accurate location of discontinuities. The area-based process is used to match the continuous surfaces.It can provide a dense disparity map. The techniques of stereo matching with adaptive window are adopted in the area-based process. It can make the results of area-based process get high precise. An integrated process is also used in this approach. It can integrate the results of feature-based process and area-based process, so that the approach can provide not only a dense disparity map but also an accurate location of discontinuities. The approach has been tested by some synthetic and nature images. From the results of matched wedding cake and matched aircraft model, we can see that the surfaces and configuration are well reconstructed. The integrated stereo matching approach can be used in 3D part recognition in intelligent assembly system and computer vision.
