影像匹配是指从数字影像上识别相关影像。它是计算机视觉和数字摄影测量中的一个基本问题。本文介绍了结构影像匹配法，它不仅要利用影像灰度值和影像特征，而且要利用它们之间的相互关系。这种方法的目的是在不需要知道数字影像的任何先验信息的情况下，对相关特征进行全自动匹配。这种方法的适用性已在非测量影像上得到验证。 Image matching refers to identifying the relevant image from the digital image. It is a fundamental issue in computer vision and digital photogrammetry. This paper introduces the structural image matching method, which not only uses the gray value of image and the image features, but also makes use of the interrelationship between them. The purpose of this method is to automatically match related features without having to know any prior information of the digital image. The applicability of this method has been validated on non-measurement images.
