A mobile object position estimation apparatus mounted in a mobile object includes a first estimation mechanism for estimating the mobile object position based on the outputs from an inertial navigation sensor device (acceleration sensor, and yaw rate sensor, or the like) mounted on the mobile object, a storage for storing map information including at least node information, a second estimation mechanism for estimating the mobile object position based on a predicted path of traveling of the mobile object predicted from the node information, and a synthesis mechanism for determining the final estimated mobile object position by synthesizing the mobile object position estimated by the first estimation mechanism and the mobile object position estimated by the second estimation mechanism.

An image processing system is provided, which includes: a front monitoring device that obtains an image of a view ahead of a vehicle; a vehicle position detecting device that detects the position and orientation of the vehicle; a map database that stores road maps; a traffic indicator position estimating portion that estimates the position of a traffic indicator () based on the shape of a road ahead of the vehicle that has been extracted from the map database, according to the position of the vehicle that has been detected by the vehicle position detecting device; an image processing region setting portion that sets an image processing region within the image obtained by the front monitoring device based on the position of the traffic indicator that has been estimated by the traffic indicator position estimating portion; and a traffic indicator detecting portion that detects the traffic indicator from the image processing region.

Image processing system and method

A carrier phase GPS positioning device is disclosed, which acquires a carrier phase accumulation value of satellite signals at one time on the mobile station side, associates plural carrier phase accumulation values on the reference station side at plural times prior to the one time with the carrier phase accumulation value on the mobile station side, and estimates an integer ambiguity included in the carrier phase accumulation value of signals transmitted from the satellite received by the mobile station.
