Abstract:

To solve the problem existing in the application of binocular stereo vision imagepair, a threestages matching preprocessing method was proposed. This method combines the wavelet denosing algorithm and histogram equalization method effectively. The random noise and Gauss noise of image are filtered and luminance difference between stereo imagepairs is balanced at the same time. Finally the contrast of imagepairs was improved by Laplace sharpen processing. The effectiveness of threestages matching preprocessing algorithm was proved by experiment. The application of the algorithm could improve the matching accuracy of stereo imagepairs effectively.
