The own position estimation part includes: a first error calculator calculating a first error of the own position from an error related to a map point calculated when the environmental map data is created; a second error calculator calculating a second error of the own position from the image captured while the mobile object is moving from positions and postures of the imaging part; and a third error calculator calculating a third error of the own position including the first and second errors.",
