Claim 0:
1. A three-dimensional model generation method executed by an information processing device, the three-dimensional model generation method comprising:
obtaining a sparse three-dimensional point cloud representing a three-dimensional shape of a subject in a three-dimensional space;
obtaining a first image of the subject shot from a first viewpoint and a second image of the subject shot from a second viewpoint;
determining a search range in the three-dimensional space, based on the sparse three-dimensional point cloud, the search range including a first three-dimensional point on the subject, the search range being a range in a shooting direction of a first camera from the first viewpoint and in which the first three-dimensional point is more likely to be present than in another range, the first three-dimensional point corresponding to a first point in the first image;
searching for a similar point that is similar to the first point, in a range in the second image which corresponds to the search range; and
generating a three-dimensional model including a three-dimensional point cloud that is denser than the sparse three-dimensional point cloud using a search result in the searching.
