Abstract

First, a displacement field (first displacement field) for deforming a first image so as to associate the first image with a second image is calculated based on information on an input corresponding point group. Then, upon a corresponding point candidate pair being input, a displacement field (second displacement field) for deforming the first image so as to associate the first image with the second image is calculated with the corresponding point candidate pair taken into consideration as well. Thereafter, a matching degree is calculated based on a difference between the two displacement fields, and a determination result indicating a match or a mismatch is displayed on a display unit.

Claims

1. An image processing apparatus, comprising:

a correspondence information acquisition unit configured to acquire correspondence information between a first image and a second image;

a corresponding point candidate acquisition unit configured to acquire a corresponding point candidate pair including a coordinate of a first point on the first image and a coordinate of a second point on the second image;

a matching degree calculation unit configured to calculate a matching degree of the corresponding point candidate pair acquired by the corresponding point candidate acquisition unit, with respect to the correspondence information acquired by the correspondence information acquisition unit; and

a display control unit configured to display a calculation result of the matching degree calculation unit on a display unit.
