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

A method of matching a feature point, the method comprising:

• generating a first position feature quantity for at least one first feature point based on a position of the at least one first feature point included in a first image, generating a first pixel value feature quantity for the at least one first feature point based on a pixel value of the at least one first feature point, generating a second position feature quantity for at least one second feature point based on a position of the at least one second feature point included in a second image, and generating a second pixel value feature quantity for the at least one second feature point based on a pixel value of the at least one second feature point;
• and
• matching the at least one first feature point and the at least one second feature point by evaluating whether or not the first position feature quantity matches the second position feature quantity and whether or not the first pixel value feature quantity matches the second pixel value feature quantity,
• wherein the first pixel value feature quantity includes the pixel value of the at least one first feature point, and
• wherein the second pixel value feature quantity includes the pixel value of the at least one second feature point.

A non-transitory computer readable medium storing a feature point matching program for causing computer to execute:

• generating a first position feature quantity for at least one first feature point based on a position of the at least one first feature point included in a first image, generating a first pixel value feature quantity for the at least one first feature point based on a pixel value of the at least one first feature point, generating a second position feature quantity for at least one second feature point based on a position of the at least one second feature point included in a second image, and generating a second pixel value feature quantity for the at least one second feature point based on a pixel value of the at least one second feature point;
• and
• matching the at least one first feature point and the at least one second feature point by evaluating whether or not the first position feature quantity matches the second position feature quantity and whether or not the first pixel value feature quantity matches the second pixel value feature quantity,
• wherein the first pixel value feature quantity includes the pixel value of the at least one first feature point, and
• wherein the second pixel value feature quantity includes the pixel value of the at least one second feature point.
