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 10):
The image collation method according to  claim 7 ,\n wherein the limiting condition regarding the consistency of the rotational angle is, regarding the feature points at first and second tentative matching points forming the pair of tentative matching points and first and second input images forming the pair of input images, that an absolute value of a difference between a first rotational angle and a second rotational angle is smaller than a first previously predetermined threshold value, the first rotational angle being a difference between a characteristic angle of the first tentative matching point in the first input image and a characteristic angle of the first tentative matching point in the second input image, the second rotational angle being a difference between a characteristic angle of the second tentative matching point in the first input image and a characteristic angle of the second tentative matching point in the second input image.
