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 8):
The position measurement apparatus according to  claim 1 , wherein\n the sensor includes an acceleration sensor, a geomagnetic sensor, and a gyro sensor, the attitude information generation unit generates attitude information by using a combination of the acceleration sensor and the geomagnetic sensor, and the gyro sensor, and the reliability generation unit generates a reliability value of an angle from a difference in azimuth angle between the attitude information obtained by the gyro sensor and the attitude information obtained by the combination of the acceleration sensor and the geomagnetic sensor.
