Imaging system for vehicle
First Claim
1. An imaging system suitable for use with a vehicle based global positioning system, the vehicle based global positioning system being operable to determine a vehicle position in response to a satellite communication and to provide position data of the vehicle position, said imaging system, comprising:
- an imaging sensor operable to capture images of a scene exteriorly of the vehicle, said imaging sensor being positioned at one of an interior portion of the vehicle and an exterior portion of the vehicle; and
a control operable to process said images and to track vehicle movement via processing of said images, said control being operable to receive the position data from the vehicle based global positioning system, the position data including previous location data indicating a previous location of the vehicle determined by the vehicle based global positioning system before a satellite communication to the vehicle based global positioning system is interrupted, said control being operable to determine movement data of the vehicle via image processing of said images, said control utilizing said movement data and said previous location data determined by the vehicle based global positioning system to determine a current vehicle location record when the satellite communication to the vehicle based global positioning system is interrupted.

Abstract
An imaging system suitable for use with a vehicle based global positioning system includes an imaging sensor and a control. The imaging sensor is positioned at the vehicle and may face generally forwardly with respect to the direction of travel of the vehicle. The control may be operable to provide a record of vehicle movement since the last position data derived from the vehicle based global positioning system. The imaging system may also or otherwise be suitable for use with a vehicle based magnetic compass system. The imaging system may be operable in combination with a magnetic field sensor of the magnetic compass system to provide a substantially continuously calibrated heading indication, which is substantially resistant to local magnetic anomalies and changes in vehicle inclination. The imaging sensor may be associated with one or more other accessories of the vehicle.
