Abstract

A two-dimensional image obtained by capturing a scene including an object is obtained. Parameters indicating capturing position and capturing orientation of the two-dimensional image are obtained. A three-dimensional shape model representing a three-dimensional shape of the object is obtained. Two-dimensional geometrical features of the object are extracted from the two-dimensional image. Three-dimensional information with respect to a surface of the object close to each of the two-dimensional geometrical features is calculated from the three-dimensional shape model. Three-dimensional geometrical features in the three-dimensional shape model, corresponding to the two-dimensional geometrical features are calculated based on the two-dimensional geometrical features, the parameters, and the calculated three-dimensional information.
