摘　　要：INS/SAR组合导航系统对合成孔径雷达(SAR)图像的角点提取精度、实时性、可靠性要求较高,为此,提出一种结合曲率尺度空间与Harris算子的角点提取算法,用局部Harris算子定位用曲率尺度空间法提取出的角点。实验结果表明,该算法实时性好、精度高、冗余度低。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.
