Abstract
A fundamental matrix generation apparatus performs: detecting three or more feature point pairs from a first image and a second image; detecting, for each of the feature point pairs, a derived point pair that is a pair of a derived point separated by a first distance in a first direction from a point on the first image included in the feature point pair and a derived point separated by a second distance in a second direction from a point on the second image included in the feature point pair; generating a fundamental matrix or the fundamental matrix representing an epipolar constraint on a point on the first image and a point on the second image by using the detected feature point pairs and derived point pairs.
