ABSTRACT:
The first values of position and orientation of an image sensing device are obtained by using positions of all indices in a frame image. Indices having the same inherent information between a first index group (FIG) in the frame image and a second index group (SIG) in a preceding frame image are detected as a common index. If the information of the SIG contains information different from that of the FIG, second values of the position and orientation are obtained by using the positions of the common indices in the preceding frame image. If the information of the FIG contains information different from that of the SIG, third values of the position and orientation are obtained by using the positions of the common indices in the frame image. The first values are corrected by using correction values based on the obtained first to third values.
