More Information
Summary:The invention discloses a fast stereo matching method based on color partitioning and self-adaptive window, comprising the following steps of: (1) constructing a matching cost based on color partitioning; (2) constructing a matching cost based on self-adaptive window; (3) constructing a combined matching cost based on the color partitioning and the self-adaptive window; and (4) optimizing the combined matching cost by adopting a local optimization method in order to obtain a dense disparity map. The method of the invention not only can improve the matching precision of parallax discontinuous areas and low veins areas, but also obtains the parallax which is comparable with that of current dominant algorithms. In addition, the processing time of the disclosed method is enhanced by about 19 to 35 times compared with the current excellent local methods, and both the matching speed and the matching precision are taken into consideration.
