摘要：A method, positioning accurately the corner and cross points on digital images. is presented in this paper. Base.d on thefeature extraction by interest operator. the lines. forming the corner and cross point, are located firstly. Then theirintersection can be detennined. Various simulated images have been used in the test of position accuracy, which is muchbetter than other method's one. The algorithm has been applicated in the relative orientation of real digital image pairs andthe results are quite satisfactory
