Abstract:
In a position measurement apparatus, to maintain accuracy of a trajectory even when the frequency of acquisition of absolute position information is reduced, a movement information generation unit generates movement information including a movement distance and a movement direction of a device of interest based on a sensor value, and a reliability generation unit generates reliability information indicating a reliability value of the movement information. An amount of distance correction and an amount of angle correction to be made every predetermined number of steps are determined based on the reliability information and the movement information, and the distance and the angle are corrected every predetermined number of steps starting from the latest already-corrected position information.

Claim (Index 16):
A position correction method comprising:\n estimating a position of a device of interest based on a sensor value acquired by a sensor; measuring absolute coordinates of the device of interest; and correcting the estimated position of the device of interest based on the absolute coordinates of the device of interest, the estimating of the position including\n generating attitude information associated with the device of interest based on the sensor value, \n generating movement information including a movement distance of the device of interest and a movement direction of the device of interest based on the attitude information, and \n generating reliability information indicating a reliability value of the movement information based on the sensor value, \n the correcting including\n determining an amount of distance correction to be made every predetermined number of steps and an amount of angle correction to be made every predetermined number of steps based on the reliability information and the movement information, and \n correcting the movement distance and the movement direction every predetermine number of steps starting from latest already-corrected position information associated with the device of interest.
