Claim 13:
14. A three-dimensional model generation device comprising:
a processor; and
memory, wherein
using the memory, the processor:
obtains a sparse three-dimensional point cloud representing a three-dimensional shape of a subject in a three-dimensional space;
obtains a first image of the subject shot from a first viewpoint and a second image of the subject shot from a second viewpoint;
determines 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;
searches 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
generates a three-dimensional model including a three-dimensional point cloud that is denser than the sparse three-dimensional point cloud using a result of the search.
