Abstract
According to one embodiment, a position estimation device includes an acquirer that acquires wheel rotation information as information on rotation of wheels of a mobile structure and object information on an object, and an estimator that estimates a position of the mobile structure by calculating a directional deviation of a mobile structure as change in a direction of the mobile structure from the wheel rotation information and a predetermined direction parameter and calculating the direction of the mobile structure from the directional deviation of the mobile structure, and corrects the direction parameter on the basis of the directional deviation of the mobile structure and an object directional deviation as variation in a direction of the object relative to the mobile structure by calculating the object directional deviation from the object information.
