Abstract

The invention discloses a stereo matching method based on a distance difference and a color difference. A step of calculating a matching cost of a current matching pair under a parallax error value comprises the following sub steps of: 1) constructing a supporting window; 2) layering; 3) determining distance weights of k layers of pixel layers in a left graph and distance weights of k layers of pixel layers in a right graph respectively; 4) determining color weights of the k layers of pixel layers in the left graph and color weights of the k layers of pixel layers in the right graph respectively; 5) determining a difference value of (wsize2-1) surrounding pixel matching pairs in a red, green and blue (RGB) space under the current parallax error value; and 6) calculating the matching cost of the current matching pairs p and q according to the distance weights, the color weights and the difference value. By the stereo matching method based on the distance difference and the color difference, values of relevant weights can be calculated by taking a layer as a unit; relative to independent calculation of each pixel, the calculated quantity is reduced; furthermore, influence of the distance weights and the color difference is considered at the same time, so the final parallax error value result is more precise.
