摘要： In order to provide a curved surface model generating technique which makes use of both advantages of a modeling method by using distance image data and a modeling method by using silhouette data while photographic and measurement data from less angles are utilized, firstly a curved surface model generating section inputs 2D color image data and distance image data. When silhouette image data are extracted from the 2D color image data, initial model data are generated by the Volume Intersection method or the like. The distance image data are converted into world coordinate values by using photographing position/posture data. In a fitting processing section, a fidelity where the distance with the distance image data is used as a measure and a fidelity where the distance with the silhouette image data is used as a measure are added to be evaluated, and a curved surface is fitted to initial model data so that curve surface model data are generated.
