Abstract
A calibration method and apparatus acquires a correction value to correct position and orientation measured by using a position and orientation sensor provided on a physical object by measuring position and orientation of the physical object when a calibration is started, generating an image of the virtual object existing on a plane on which the physical object can be moved, and displaying a composite image formed by superimposing the image of the virtual object on the captured image of the physical object. Additional features include detecting an instruction indicating that a predetermined positional relationship between the physical object and the virtual object is satisfied, providing a second measuring position and orientation of the physical object when the instruction is detected, and acquiring the correction value expressed by parallel movement of the physical object on the plane and rotation of the physical object about an axis set in the direction perpendicular to the plane on the basis of the first position and orientation measured and the second position and orientation measured.
