When a feature point extractor sets feature points on one of the images acquired by a first and second image acquirer, a template setting unit sets a base template containing a feature point onto an edge-extracted image of the acquired image. If the image within the base template is segmented by an edge, the template setting unit sets a transformed template, wherein a segmented sub-region that does not contain the feature point is deleted from the base template, and a region equal in area to the deleted region is added to the sub-region that does contain the feature point. A distance computing unit conducts template matching with respect to the one or more other images using either the base template or the transformed template, and computes the shooting distance to the matching feature point. |
