Abstract

A position estimating device is provided with an image acquiring unit that acquires images around a moving body, a moving body movement amount estimating unit that estimates an amount of movement of the moving body based on the images, and a moving body position estimating unit that estimates the position of the moving body based on the estimated amount of movement. The moving body movement amount estimating unit includes a tracking unit that tracks a first feature point to a second feature point, a distance calculating unit that calculates the distance from the moving body to the second feature point, an azimuth estimating unit that estimates the azimuth of the moving body based on the distance from the moving body to the second feature point, and a movement amount estimating unit which estimates the amount of movement of the moving body based on the azimuth of the moving body.
