将图像从笛卡尔坐标系上转换到对数极坐标上，这样做便于将笛卡尔坐标系上存在缩放和旋转关系的图像转换成对数极坐标下的具有平移关系的图像，然后就可以用相位相关检测算法进行相关检测，得到两幅图像的相关性(Convert an image Cartesian to polar coordinates on a logarithmic, this facilitates the translation relations image with the next image conversion to a logarithmic scale and rotate relationship exists between the Cartesian coordinates polar coordinates, then you can use phase correlation detection algorithm for correlation detection, the correlation between two images obtained)
