1. A three-dimensional modeling apparatus comprising:

  • an image obtaining section that obtains image sets picked up by a stereoscopic camera;

    a generating section that generates three-dimensional models of an object based on each of the obtained image sets;

    a three-dimensional model selecting section that selects a first three-dimensional model and a second three-dimensional model to be superimposed on the first three-dimensional model among the generated three-dimensional models;

    an extracting section which extracts first feature points from the selected first three-dimensional model and second feature points from the selected second three-dimensional model;

    a feature-point selecting section that selects feature points having a closer distance to the stereoscopic camera from the extracted first feature points and the extracted second feature points, respectively;

    a parameter obtaining section that obtains a transformation parameter for transforming a coordinate of the second three-dimensional model into a coordinate in a coordinate system of the first three-dimensional model based on the selected first and second feature points;

    a transforming section that transforms the coordinate of the second three-dimensional model into the coordinate in the coordinate system of the first three-dimensional model using the transformation parameter; and

    a superimposing section that superimposes the second three-dimensional model having a transformed coordinate on the first three-dimensional model.
