Patent ID: 6937235

Claim:
A three-dimensional object surface shape modeling apparatus for generating curved surface model data of a three-dimensional object in a virtual space treated by a computer, the apparatus comprising: an initial model data generator for generating initial model data for generating the curved surface model data in the virtual space; an input device for inputting a measuring point group as a collective of three-dimensional coordinate data obtained by measuring the three-dimensional object existing in an actual space; a silhouette data generator for generating silhouette data from two-dimensional image data obtained by photographing the three-dimensional object existing in the actual space; a first calculator for calculating a first fidelity representing approximation between the initial model data and the measuring point group; a second calculator for calculating a second fidelity representing approximation between the initial model data and the silhouette data; and a curved surface model data generator for generating curved surface model data of the three-dimensional object by deforming the initial model data based on the first fidelity and the second fidelity.
