中文说明：基于SIFT的图像配准程序 SIFT特征匹配算法是目前国内外特征点匹配研究领域的热点与难点,其匹配能力较强,可以处理两幅图像之间发生平移、旋转、仿射变换情况下的匹配问题,甚至在某种程度上对任意角度拍摄的图像也具备较为稳定的特征匹配能力
English Description：
SIFT feature matching algorithm, an image registration program based on SIFT, is a hotspot and difficulty in the field of feature point matching research at home and abroad. It has strong matching ability, and can deal with the matching problems in the case of translation, rotation and affine transformation between two images, and even has relatively stable feature matching ability for images taken from any angle to some extent
