1. A three-dimensional CG model generator for generating a three-dimensional CG model of a three-dimensional object represented in a two-dimensional image, based on information from the two-dimensional image representing the three-dimensional object supplied thereto, comprising:

  • an image inputting part for receiving image data of the object taken from a certain viewpoint;

    a basic pose information storing part of storing pose information on all patterns of a basic geometric model as basic pose information, the pose information indicating a pose with relationships of vertexes and edges of the image projected two-dimensionally;

    a pose information designating part for acquiring the pose information be designating a vertex and an edge of the object represented in the supplied image projected two-dimensionally;

    a pose matching part for performing pose matching be comparing the pose information acquired by the pose information designating part and the basic pose information stored in the basic pose information storing part, and specifying a basic geometric model having corresponding pose information and a corresponding pose; and

    an automatic fitting part for deforming and adjusting the pose of the basic geometric model specified by the pose matching part so as to conform to the pose of the supplied image;

    wherein the three-dimensional CG model of the object is generated based on the pose information of the supplied image.
