According to the rising problems in the process of data processing such as data registration,texture mapping and target identification,it presents an algorithm of corner detecting,aiming at easily founding the corresponding points between adjacent stations.First,make each station's three-dimensional distance image into two-dimensional gray image,using the relative position between the instrument center and scanned target;second,use SUSAN operator to detect the corner points in the two dimensional gray image;last,match the corner points that have been detected,using the stitching precision to prove the effectiveness of this algorithm.
