The method of sampling feature points for image matching includes: dividing a first image into a plurality of regions corresponding to a number of feature points to be sampled; extracting a sampled feature point from each of the regions such that a distance between a sampled feature point of one region and a sampled feature point of another region satisfies a predetermined condition; and estimating a homography on the basis of the extracted sampled feature points and corresponding sampled feature points of a second image to be matched with the first image."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of sampling feature points, image matching method using the same, and image matching apparatus","description":"A method of sampling feature points, an image matching method using the same, and an image matching processor are disclosed.
