PROBLEM TO BE SOLVED: To provide an apparatus that can generate an image displaying a contour image of a back surface and is more convenient than a moire camera.SOLUTION: A 3D measurement device 10 photographs a back surface of an evaluation object person to generate a texture image and 3D shape data. A contour image generation unit 14 generates a contour image of the back surface from the 3D shape data. An image compositing unit 16 composites the contour image with the texture image to generate a composite image similar to a moire image formed by a moire camera. The contour image generation unit 14 may generate the contour image in an observation direction different from a photographing direction of the 3D measurement device 10 from the 3D shape data and may generate the composite image with the texture image.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2020,JPO&INPIT
