Abstract

A method for reducing matching errors in disparity images by information in zoom images is revealed. Images with different local length captured by two zoom cameras are given. Perform image and zoom rectification of the images to get a new image center. Then cross checking is used to check whether the corresponding points of each pixel in the image are matched for marking the pixel as a reliable point or an unreliable point. Computation of stereo matching cost is carried out when a reliable point is marked. Otherwise stereo matching and zoom image matching are performed. The matching cost is aggregated by weighting so as to select the matching cost that mostly represents the similarity. Use WTA to get final matching results and disparities thereof for disparity selection. Lastly use a median filter to remove noise from the image for disparity refinement and get a final disparity image.
