摘　　要：灰度匹配新算法是在传统算法基础上改进而来。它先根据信息量的大小选取部分影像进行粗匹配,粗匹配通过后再用相关系数法进行精匹配。实验表明,本文所提出的方法较现存的方法精度高、速度快。A new algorithm of gray - scale matching is presented in this paper. It is improved on the base of the normalized pattern algorithm. According to the quantity of the information,a part of the image is chosen to execute the gerenal matching,then an accurate matching is executed using the correlation coefficient. The experiment indicates that the precision of the method improved in the paper is higher than any others,and the velocity is fast too.
