Claim:
An image processing apparatus comprising: an acquisition unit adapted to acquire a captured image from an image capturing device that captures a plurality of images of a physical space on which a plurality of indices are allocated; a registration unit adapted to acquire, for each index included in the captured image acquired by said acquisition unit, a set of index identification information unique to an interest index, image coordinates of the interest index in the captured image, and image identification information unique to the captured image, which are obtained by applying identification processing to the interest index included in the captured image acquired by said acquisition unit, and to register the acquired set in a memory; a management unit adapted to manage the numbers of times of previous identification for respective pieces of index identification information of indices that undergo the identification processing by said registration unit; a display unit adapted to display the number of times managed by said management unit in association with index identification information in the set to be registered, every time said registration unit registers the set; and a calculation unit adapted to calculate, using a set group registered in the memory, positions and orientations of indices corresponding to the set groups.
