An information processing device includes: a posture change determining unit that determines, based on an output value of an inertial sensor, whether a posture state of a moving object has changed; a reference orientation generating unit that, when it is determined that the posture state of the moving object has changed from a first posture state into a second posture state, generates a reference orientation corresponding to an orientation of the moving object at that time calculated from the output value of the inertial sensor; and an orientation error calculating unit that, when it is determined that the posture state of the moving object has changed from the second posture state into the first posture state, calculates an error of an orientation of the moving object according to the reference orientation, and an orientation at that time calculated from the output value of the inertial sensor.
