Title:
PROGRAM, DEVICE, AND METHOD FOR CALCULATING SIMILARITY BETWEEN IMAGES REPRESENTED BY FEATURE POINT SET
Document Type and Number:
Japanese Patent JP2014225168
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a program, device, and method for calculating, when markers based on a reference image are arranged on a plane, and the reference image is present in a query image, the similarity between the query image and reference image as precisely as possible.SOLUTION: A device of the present invention includes similarity calculation means for receiving the input of the feature point p' of a query image, the feature point p of a reference image, and a Homography matrix H projected from the reference image to the query image, calculating a rotation translation matrix T from the reference image to a plane image corresponding to the query image, and calculating the similarity between the feature point of the query image and a point obtained by projecting and converting a plurality of other feature points of the reference image by using the Homography matrix H and rotation translation matrix T.
