Abstract
A stereo matching system and a stereo matching method using the same. Here, a Sum of Edge Differences (SED) method as a disparity estimation method utilizing edge information is added to a disparity estimation method utilizing a local method to perform stereo matching. As such, it is possible to correct false matching in a non-texture region generated when stereo matching is performed using only a local method, thereby enabling good stereo matching.
Claims20
A stereo matching system comprising:
- a stereo image obtaining part adapted to obtain a left image and a right image;
- a first disparity estimation part adapted to estimate disparity of the left image and the right image utilizing a local method;
- an edge information obtaining part adapted to obtain edge information from the left image and the right image;
- a second disparity estimation part adapted to estimate disparity through Sum of Edge Differences (SED) utilizing the edge information;
- and
- a disparity synthesizing part adapted to synthesize disparities of the first disparity estimation part and the second disparity estimation part to produce a disparity map.
