POSITION CALCULATION DEVICE, POSITION CALCULATION METHOD, AND PROGRAM STORAGE MEDIUM

WIPO Patent Application WO/2023/181349

A1

A position calculation device according to the present invention is provided with an acquisition unit and a confirmation unit in order to improve the calculation precision of a position of an autonomous vehicle calculated using position information transmitted by the autonomous vehicle. The acquisition unit acquires identification information transmitted at a predetermined transmission timing by the autonomous vehicle. The identification information includes unique vehicle body information given to the autonomous vehicle, position information representing the position of the autonomous vehicle, and time information. The confirmation unit uses a predetermined standard movement pattern to select the most likely measured position as the position of the autonomous vehicle from among measured positions, which are the positions of the autonomous vehicle represented by the position information included in each of the plurality of pieces of identification information that have been acquired. The confirmation unit confirms the selected measured position as the position of the autonomous vehicle.
