PROBLEM TO BE SOLVED: To realize a processing for three-dimensionally extracting data on an object by irradiating a part of the object for obtaining grid projection, recording the picture of the part of the object through the use of a recording device forming an angle with a light beam main direction and extracting the outline of grid projection in the part of the object with a recording curve showing passage in the difference of luminance to the grid projection of the picture. SOLUTION: This processing is supplied to especially extract data on a face. For recording data on the face, the face 20 is illuminated through a grid 30 for obtaining the projection of the grid on the face by using a light source 10. A recording device 40 is arranged at an angle A equal to about 60 degrees. The decided part of a head corresponding to about half of the face, which is data between a nose and ears, is recorded in the picture. The recorded picture is formed of the bands of different illuminations, which correspond to grid projection 30. A file containing the digital picture is transmitted to a central processor 50 and data is restored by it. |
