CALCULATION METHOD, CALCULATION PROGRAM, AND INFORMATION PROCESSING DEVICE

An information processing apparatus acquires a first vector (16A-1), a second vector (16A-2), and a first translation point (17A) from first measurement information measured by a first sensor. The information processing apparatus acquires a third vector (16B-3), a fourth vector (16B-4), and a second translation point (17B) from second measurement information measured by a second sensor. The first vector (16A-1) and the third vector and (16B-3) are parallel and in the same direction in a real space. The second vector (16A-2) and the fourth vector (16B-4) are parallel and in the same direction in the real space. The first translation point (17A) and the first translation point (17B) are located at the same position in the real space. The information processing apparatus calculates a rotation angle and a translation distance on the basis of the first to fourth vectors and the first and second translation points, and stores the rotation angle and the translation distance in a storage device.
