<P>PROBLEM TO BE SOLVED: To provide a technology for determining an attitude to an imaging device, of an attitude sensor mounted on the imaging device, in consideration of frequency taken by the attitude. <P>SOLUTION: A coordinate value in a picked-up image of an index in the picked-up image by the imaging device 1020 on which the attitude sensor 1010 is mounted is detected by an index detection part 1040. A contribution degree calculation part 1070 acquires a contribution degree corresponding to a frequency in which the imaging device 1020 is positioned with an attitude shown by attitude information included in position attitude information of the imaging device 1020 at an imaging time. A data management part 1060 creates a set of the coordinate value and the attitude information measured by the attitude sensor 1010 at the imaging time of the picked-up image relative to each index. A calibration information calculation part 1090 determines the attitude of the attitude sensor 1010 to the imaging device 1020 by using the position attitude information, a parameter value, and the set created relative to each index. <P>COPYRIGHT: (C)2009,JPO&INPIT |
