Abstract:
A region projected with pattern light in an image sensed by an image sensing unit which senses an image of a target object projected with pattern light is specified. Geometric features of the target object are searched for from a region other than the region projected with the pattern light in the sensed image based on the specified region. A position and orientation of the target object are derived based on the searched geometric features of the target object and geometric features of a model of the target object.
