Abstract:
1. An information processing apparatus comprising: an orientation measurement value acquisition unit adapted to acquire (a) an orientation measurement value measured by an orientation sensor for an image capturing apparatus mounted on the image capturing apparatus, and (b) an orientation measurement value measured by an orientation sensor for a physical object mounted on the physical object to be captured by the image capturing apparatus; an image acquisition unit adapted to acquire an image of the physical object captured by the image capturing apparatus; an image coordinate acquisition unit adapted to acquire image coordinates on the image of indices allocated on the physical object; a setting unit adapted to set a given value as an initial value of a relative value between (a) an azimuth error included in the orientation measurement value of the orientation sensor for the image capturing apparatus and (b) an azimuth error included in the orientation measurement value of the orientation sensor for the physical object; and a calculation unit adapted to calculate both of (a) allocation information of the orientation sensor for the image capturing apparatus with respect to the image capturing apparatus, and (b) allocation information of the orientation sensor for the physical object with respect to the physical object, using the orientation measurement value measured by the orientation sensor for the image capturing apparatus, the orientation measurement value measured by the orientation sensor for the physical object, the image coordinates, and the given value being updated repeatedly during calculating both of the allocation information.
