The traditional gray correlation matching algorithm can not detect the angle and scale information.So,this paper presents a method to detect the angle and scale of the target by multiple templates with angle and scale information created by existing template.It analyses the size of the template extension and gives a method for peak value segmentation according to the distribution of the four-dimensional correlation coefficient.Because of the large amount of data calculation,it introduces some features about correlation coefficient and a fast search method.The Matlab simulation shows that the method can overcome error matching point when using four-dimension correlation coefficient as coefficient and correctly match the target in a small change range of angles and scale.
