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 1):
A position measurement apparatus comprising:\n a position estimation unit configured to estimate a position of a device of interest based on a sensor value acquired from a sensor; an absolute coordinate measurement unit configured to measure absolute coordinates of the device of interest; and a correction processing unit configured to correct the position of the device of interest estimated by the position estimation unit based on the absolute coordinates of the device of interest measured by the absolute coordinate measurement unit, the position estimation unit including\n an attitude information generation unit configured to generate attitude information associated with the device of interest based on the sensor value, \n a movement information generation unit configured to generate, based on the attitude information, movement information including a movement distance of the device of interest and a movement direction of the device of interest, and \n a reliability generation unit configured to generate, based on the sensor value, reliability information indicating a reliability value of the movement information, the correction processing unit being configured to \n determine 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 correct 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.
