PROBLEM TO BE SOLVED: To provide a corresponding point search device, a camera posture estimation device and programs for these capable of achieving high accuracy of subject recognition and camera posture estimation by reducing false correspondence of feature points.SOLUTION: A corresponding point search device 10 includes: feature point extraction means 12 for detecting feature points from a plurality of images by utilizing local feature quantity calculation method, and calculating feature vectors; corresponding point search means 13 for searching by using a combination of feature points in which the feature vectors are similar between the plurality of images as corresponding points; Delaunay triangle division means 14 for performing Delaunay triangle division with each feature point searched as the corresponding point as an apex; topology evaluation means 15 for evaluating whether a phase of each triangle is the same type or not by comparing triangles with each other in which the corresponding points are made to be apexes in the plurality of images and determining whether a connection relation of apexes of each of the triangles is the same type or not; and false correspondence exclusion means 16 for excluding the apexes of the triangle whose phase is evaluated not to be the same from the corresponding point. |
