A first calculator calculates a relative position and a relative attitude of a vehicle based on images captured by an image capturing apparatus mounted on the vehicle. A second calculator extracts one marker from an image captured by the image capturing apparatus, and calculates an absolute position and an absolute attitude of the vehicle based on the position and the attitude of the one extracted marker. A corrector corrects the relative position and the relative attitude based on the absolute position and the absolute attitude to generate a corrected position and a corrected attitude of the vehicle. When an angular difference between a traveling direction of the vehicle having the corrected position and the corrected attitude, and the direction of the passageway is smaller than a predetermined threshold, the corrector corrects the relative attitude based on the direction of the passageway, instead of the absolute attitude.
