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 2):
The image collation device according to  claim 1 , further comprising:\n a K-neighbor search unit configured to extract the pairs of tentative matching points that are neighbors from all pairs of the tentative matching points on the basis of a set of feature points of k neighbors of each feature point in the pair of tentative matching points, wherein the spatial verification unit evaluates the degree of similarity between the pair of input images on the basis of all of the limiting conditions for each pair of tentative matching points that are neighbors extracted by the K-neighbor search unit.
