| Abstract: | INS/SAR integrated navigation system required the matching method of SAR images and optical images to be fast and precise. In this paper, the corner features was extracted using a method combining curvature scale space and Harris operator firstly, and then the corner feature was matched using restriction of distance, coner value and edges. Being proved via the experiment, the main-line-pairs matching method in the article acted well and met the requirement of the navigation system |
