| Abstract: | Corner Matching Method（CMM） of Synthetic Aperture Radar（SAR） images in INS/SAR integrated navigation system require the corner extraction to be fast,precise and dependable.Aiming at the problem,this paper puts forward a new corner detecting method combining curvature scale space and Harris operator,in which the partial Harris operator is used to locate the corner detected by curvature scale space method.Being proved via the experiment,the method has high precision,low redundancy and good real time ability to meet the requirement of the corner detecting in INS/SAR integrated navigation system. |
