Abstract:
An image collation device includes: a tentative matching point extraction unit configured to extract a plurality of tentative matching points that are pairs of corresponding feature points between a pair of input images; and a spatial verification unit configured to evaluate a degree of similarity between the pair of input images on the basis of all of a limiting conditions regarding consistency of a scale factor, a limiting conditions regarding consistency of a rotational angle, and a limiting conditions regarding consistency of a relative positional relationship according to a comparison of or a difference between geometric transformation parameters of the tentative matching points for each of the pairs of tentative matching points that is a combination of the tentative matching points extracted by the tentative matching point extraction unit.

Claim (Index 6):
The image collation device according to  claim 1 , wherein the spatial verification unit evaluates the degree of similarity between the pair of input images on the basis of the pair of tentative matching points satisfying all of the limiting condition regarding the consistency of the scale factor, the limiting condition regarding the consistency of the rotational angle, and the limiting condition regarding the consistency of the relative positional relationship.
