Patent ID: 7272255

Claim:
A three-dimensional geometric model generation apparatus for generating a three-dimensional geometric model indicating visual information of a thee-dimensional body, said thee-dimensional geometric model generation apparatus comprising: light radiation means for simultaneously radiating light against a predetermined plane of said three-dimensional body from a frontal direction, a left and lower direction, and a right and lower direction of the predetermined plane to uniformly illuminate said predetermined plane; photography means for photographing said predetermined plane of said thee-dimensional body, to which said light is radiated, from at least one direction to acquire an image of said predetermined plane of said thee-dimensional body having neither a shadow nor shading; based on three-dimensional shape data indicating a thee-dimensional shape of said predetermined plane of said thee-dimensional body, and said image, by acquiring a brightness value at each point of said thee-dimensional shape of said three-dimensional body as said visual information, means for generating said three-dimensional geometric model of said three-dimensional body; a main body section having a central part thereof sunken in a concave shape; and a frontal-direction light radiation means provided in said center part of said main body section, a left and a right light radiation means provided in arms provided in a left and a right of said main body section respectively, and said photography means provided in fronts of the right and the left of said main body section respectively.
