PROBLEM TO BE SOLVED: To sufficiently establish practical usability by allowing a high-speed processing. SOLUTION: From the center of each plane of a polygon for enclosing a three-dimensional object, the image when photographing the object is acquired (S101), and the distance histogram and distance profile from the acquired outline image to an edge are formed (S103). The image of the three-dimensional object is taken by a camera (S201), and its distance histogram and distance profile are formed (S205). The matching of the distance histogram calculated for the profile of the three-dimensional object with the distance histogram of the model data is performed (S207), and the matching of an actual image with a model data image is performed by use of the distance profiles (S209). Further, candidates are narrowed by outline matching (S211), and the position and direction of the camera are precisely determined (S213).
