Position Estimating Device

The present invention provides a position estimating device for accurately estimating the position of a moving body. This position estimating device is provided with an image acquiring unit which acquires images around the moving body, a moving body movement amount estimating unit which estimates an amount of movement of the moving body on the basis of the images acquired by the image acquiring unit, and a moving body position estimating unit which estimates the position of the moving body on the basis of the amount of movement estimated by the moving body movement amount estimating unit, wherein the moving body movement amount estimating unit comprises: a tracking unit which tracks a first feature point to a second feature point; a distance calculating unit which calculates the distance from the moving body to the second feature point that has been tracked by the tracking unit; an azimuth estimating unit which estimates the azimuth of the moving body on the basis of the distance from the moving body to the second feature point, calculated by the distance calculating unit; and a movement amount estimating unit which estimates the amount of movement of the moving body on the basis of the azimuth of the moving body, estimated by the azimuth estimating unit.
