METHOD OF SAMPLING FEATURE POINTS, IMAGE MATCHING METHOD USING THE SAME, AND IMAGE MATCHING APPARATUS |
摘要 |
A method of sampling feature points, an image matching method using the same, and an image matching processor are disclosed. 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. |

1. A method of sampling feature points for image matching, the method comprising:
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. |
