图像匹配是三维重建中的一个关键部分。在立体视觉中，为了得到空间一点的三维几何信息，需要从不同的视点方向获取的两幅(或者多幅)图像中正确找到这一个点在不同的图像中的投影点，这一个过程就叫做图像匹配(mIageMatchnig).所以图像匹配是立体视觉系统的核心，也是实现图像理解的基础。

-Three-dimensional reconstruction of the image matching is a key part of. In stereo vision, in order to obtain three-dimensional geometry of space that needs to get directions from a different point of view of two (or multiple) images correctly find this a point in a different image of the projection point, which is called a process Image Matching (mIageMatchnig). Therefore, the image matching is the core of three-dimensional vision system, but also to understand the basis for realization of the image. .
