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.
