<P>PROBLEM TO BE SOLVED: To provide a technique that improves accuracy of alignment for an object having a repetition pattern and a similar line segment. <P>SOLUTION: An image input unit 110 acquires an image of a real space arranged with a real object having an appearance represented by a plurality of segments. A model data storage 120 manages prescription data prescribing each segment belonging to a group within a virtual space for every group, when a segment group for constituting a three-dimensional virtual object simulating the appearance of the real object is divided into a plurality of groups. A position attitude computation unit 130 selects a group from a plurality of groups one by one so as not to be overlapped. Whenever selecting one group, the position attitude information indicating a general position attitude of an image viewpoint is updated by using the prescription data prescribing the segment belonging to the selected group and the image of the real space. Then, the position attitude information updated multiple times is output as the position attitude information indicating the position attitude of the last viewpoint. <P>COPYRIGHT: (C)2010,JPO&INPIT |
