Abstract
Enabled is to estimate a self-position even when no landmark is seen or when an article confusing the landmark is brought in. An omnidirectional camera recognizes a vertical land-mark near a wall to determine a candidate for the self-position. On the basis of the candidate determined, a break in a map between a floor and a wall is projected on the camera image thereby to perform the matching.
