【Abstract】 Image matching based on feature point is the key technology in automatic relative orientation.Nowadays,feature detectors such as Frstner、Moravec、Harris、SIFT are being applied widely in photogrammetry.What are the respective characteristics of them? And how about the influence of those method on precision in relative orientation? The paper introduced the Basic principle of those methods and presented a new matching method based on combining feature detectors and descriptors.The experimental results indicate that it has the advantages of high precision,high reliability.The technique has already been used in practical application and has achieved a satisfactory result,and has a significant reference for research and application in the future.更多还原
