SURFACE SHAPE RECONSTITUTION DEVICE

PROBLEM TO BE SOLVED: To precisely reconstitute the shape and the structure of an object surface even if an object has the shape constituted by a smoothly curved surface by processing an outline part by means of synthesizing feature points obtained from multiple directions and detecting a density difference. SOLUTION: A picture taken by a TV camera 1-1 is stored in a picture memory 1-3. A feature point detection means 1-4 detects the point having the density difference in the picture as the feature point of the picture. A rotation control means 1-6 detects and controls the rotational angle of a rotation stage 1-5 rotating around a subject. A focal position control means 1-2 controls the focal position of the camera and a distance map generation means 1-7 generates a map shown by using information on the position where the focal point matches the feature point of the subject. A feature point synthesis means 1-8 synthesizes the feature points obtained from the picture and stores the reconstituted picture in a three-dimensional memory 1-9. A display means 1-10 displays and outputs the stored picture.
