摘要

Three-dimensional geometric model generation method, apparatus and record medium for generating a three-dimensional geometric model indicating visual information of a three-dimensional body, comprising: simultaneously radiating light against a predetermined plane of the three-dimensional body from a frontal direction, a left and lower direction, and a right and lower direction of the above predetermined plane to uniformly illuminate the predetermined plane; photographing a predetermined plane of the three-dimensional body, to which the light was radiated, at least from one direction to acquire an image of the predetermined plane of the three-dimensional body having neither a shadow nor shading; and based on three-dimensional shape data indicating a three-dimensional shape of a predetermined plane of the three-dimensional body, and the image that was photographed, by acquiring a brightness value at each point of the three-dimensional shape of the three-dimensional body as the visual information, generating the three-dimensional geometric model of the three-dimensional body.
