PROBLEM TO BE SOLVED: To measure with precision with a simple configuration, the solid shape of an object to be measured and the behavior of an image pickup means. SOLUTION: A correspondence relationship extracting part 2 extracts a feature point from the image of first view point image-picked up with a single- eye image pickup part 1, and a corresponding point from the image of second view point. An attitude calculation part 5 calculates attitude of the single-eye image picking-up part 1 of each view point based on the inclination in the gravity direction and the angle around gravity detected with a gravity direction detecting part 3 and an gravity-around angle detecting part 4, respectively. A line of sight vector calculating part 6 calculates the line of sight vector of each view point from such data as attitude, feature point, and corresponding point, and a translation calculating part 7 calculates the translation direction vector from the first view point to the second view point based on such data as line of sight vector, feature point, and corresponding point. A 3-dimention shape calculating part 3 calculates the 3-dimention coordinate value on a target corresponding to each feature point based on a principle of trigonometrical survey using the translation direction vector and each line of sight vectore. |
