Abstract

This paper discusses the problem of radar to optical scene matching. Because of the different imaging principles, there exists poor similarity between radar images and optical images, and for region features, only exist the relative stable common characteristics: large scale regions. This paper presents a fast and effective matching method to reach the demand of the fast orientation, which makes use of region segmentation technique to extract large scale regions in a radar image, and recognizes the large scale object in it according to the knowledge of the object region in the corresponding optical image to perform coarse location, finally using an additional template matching processing to perform fine location.
