Abstract
An optical tracking vehicle control system includes a controller adapted for computing vehicle guidance signals and a guidance subsystem adapted for receiving the guidance signals from the controller and for guiding the vehicle. An optical movement sensor is mounted on the vehicle in optical contact with a travel surface being traversed by the vehicle. The optical movement sensor is connected to the controller and provides vehicle movement signals thereto for use by the controller in computing vehicle position. The optical movement sensor can be either mounted on a gimbal for movement independent of the vehicle, or, alternatively, multiple optical movement sensors can be provided for detecting yaw movements. GNSS and inertial vehicle position tracking subsystems are also provided. Still further, a method of tracking a vehicle with an optical movement sensor is provided.
