Abstract
The distance estimation device acquires distances from a movable body at a first time and a second time to two ground objects, respectively, and acquires a distance between the two ground objects. Then, the distance estimation device calculates a moving distance of the movable body from the first time to the second time based on the acquired results. Thus, the distance estimation device calculates the moving distance of the movable body using arbitrary ground objects measurable from the movable body.
