Claim One:
1. An information processing apparatus comprising: an acquisition unit configured to acquire a captured image of a measurement target object on which a projection pattern is projected, the projection pattern being formed by arranging a plurality of geometric figure sets each having geometric figures arranged at intervals shorter than a predetermined value, at intervals longer than the predetermined value; a detection unit configured to detect the geometric figures in the projection pattern from the image; a determination unit configured to determine the geometric figure sets from the geometric figures detected by the detection unit; an identification unit configured to identify to which one of the geometric figures in the projection pattern a geometric figure detected by the detection unit corresponds, based on a result of the determination unit; a distance calculation unit configured to calculate a distance from a predetermined reference coordinate to a position on a plane of the measurement target object on which a geometric figure detected by the detection unit is projected, based on a position in the image of the geometric figure detected by the detection unit and a position in the projection pattern of a geometric figure identified by the identification unit; and a plane direction calculation unit configured to calculate a plane direction of a plane of the measurement target object on which a geometric figure set determined by the determination unit is projected, based on the distance calculated by the distance calculation unit.
