Industrial vehicle positioning system and method

A positioning system for an industrial vehicle 105 includes first and second imaging subsystems (e.g. cameras) 110A,B for acquiring first and second indicia images. An image analysis subsystem then analyzes the first and second indicia images to acquire first and second location designations. A proc...

Zusammenfassung:	A positioning system for an industrial vehicle 105 includes first and second imaging subsystems (e.g. cameras) 110A,B for acquiring first and second indicia images. An image analysis subsystem then analyzes the first and second indicia images to acquire first and second location designations. A processor then determines the location of the industrial vehicle based upon the first and second location designations. The indicia images could be of barcodes 111 or of alpha-numeric text to which optical character recognition is applied. The cameras could be video or still cameras. An independent claim is included for a vehicle having such as positioning system. The invention could find application to vehicles such as forklifts, pallet trucks or order pickers in a warehouse environment.
