Feature point matching device, feature point matching method, and non-transitory computer readable medium storing feature matching program

摘要

A feature point matching device includes a position feature generation unit for generating a position feature quantity for a feature point based on a position of the feature point included in an image, a pixel value feature generation unit for generating a pixel value feature quantity for the feature point based on a pixel value of the feature point included in the image, and a feature matching unit for matching a first feature point and a second feature point based on a degree of matching between a first position feature quantity generated from a first image and a second position feature quantity generated from a second image and a degree of matching between a first pixel value feature quantity generated from the first image and a second pixel value feature quantity generated from the second image.

主权项

1. A feature point matching device, comprising:
a position feature generation unit that generates a position feature quantity for at least one feature point based on a position of the at least one feature point included in an image; a pixel value feature generation unit that generates a pixel value feature quantity for the at least one feature point based on a pixel value of the at least one feature point included in the image; and a feature matching unit that matches at least one first feature point and at least one second feature point by evaluating whether or not a first position feature quantity matches a second position feature quantity and whether or not a first pixel value feature quantity matches a second pixel value feature quantity, the first position feature quantity being generated by the position feature generation unit from the at least one first feature point included in a first image, the second position feature quantity being generated by the position feature generation unit from the at least one second feature point included in a second image, the first pixel value feature quantity being generated by the pixel value feature generation unit from the at least one first feature point, and the second pixel value feature quantity being generated by the pixel value feature generation unit from the at least one second feature point, wherein the pixel value feature quantity includes the pixel value of the at least one feature point.
