Visual perception matching cost on binocular stereo images

摘要

In a method, a first image of a subject is taken from a first viewpoint (602). The first image of the subject is composed of a first plurality of pixels. A second image of the subject is taken from a second viewpoint (604). The second image of the subject is composed of a second plurality of pixels. Pixels in the first plurality of pixels in the first image correspond to pixels in the second plurality of pixels in the second image. Corresponding pixels lie on first epipolar lines in the first image and on second epipolar lines in the second image. The first and second images are rectified (606) to make the first and second epipolar lines parallel to one another and to place corresponding pixels in the first and second images on one of a plurality of pairs of common scanlines. For at least one pair of common scanlines, a corresponding pixel is found in the second image for each pixel in the first image such that a visual perception matching cost (VPMC) is minimized (608).
