采用边缘匹配和区域相关相结合的办法,用Gauss-Laplace算子首先对图像进行运算,提取图像的边缘像素,并根据一定约束条件匹配边缘像素,再将图像对视作对称,以相关值互为最大来确定其余点的匹配关系。用该方法处理经过良好校正的图像对,在VC++环境下可实现浓密视差图的快速提取。
In this paper, we integrate feature-based image matching method with feature-based one. Zero-crossing edge points are first extracted from image pairs with the Gauss-Laplace operator caculating. They are matched according some constraint conditions. Then, being looked as symmetries, image pairs’ other point to point correspondences are searched from two directions by pixel neighbor area correlation values. Applying this approach, we have designed Visual C++ programs for rectified image pairs and extracted their condense disparity map not only fast but also efficiently.
