Abstract: A three-dimensional model generation method includes: obtaining subject information including a plurality of positions on a subject in a three-dimensional space; obtaining a first camera image of the subject from a first viewpoint and a second camera image of the subject from a second viewpoint; determining a search range in the three-dimensional space, including a first three-dimensional point on the subject corresponding to a first point in the first camera image, based on the subject information and without using map information that is generated by camera calibration executed by shooting the subject from a plurality of viewpoints and includes three-dimensional points each indicating a position on the subject in the three-dimensional space; searching for a similar point that is similar to the first point, in a range in the second camera image corresponding to the search range; and a generating three-dimensional model using the search result.
