| 摘 要： | 通过引入Tchebichef离散正交矩提出了一种新的基于双目立体匹配的方法，该方法利用了Tchebichef离散正交矩在图像空间中的正交性来描述图像的灰度分布特征，然后根据该分布特征对图像对进逐行逐像素匹配，视差计算通过逆变换或者通过比较重建图像的灰度值进行估计，从而得到视差图。给出了利用正交矩处理图像对的重建结果和立体匹配结果。试验结果表明，该方法是可行和有效的。

| Abstract: | A new stereo matching approach based on Tchebichef discrete orthogonal moments is proposed. This method described the image intensity distribution character using the orthogonal property of Tchebichef discrete orthogonal moments in image coordinate space, after that, mathed the pixel in stereo image pair according the distribution characters; at last, computed the disparity by the inverse transformation or comparing the intensity of the reconstructed image. The result was given using Tchebichef discrete orthogonal moments to process image stereo matching. The result indicates that our algorithm using Tchebichef discrete orthogonal moments to process stereo matching is possible and valid. |
