OPTICAL NAVIGATION SYSTEM FOR VEHICLES

WIPO Patent Application WO2006049750

A3

An optical vehicle motion detection system and a method for detecting motion of a vehicle (402, 600). The optical vehicle motion detection system has at least one optical detector (102, 300, 404, 406, 500, 602, 604, 606, 608) on a vehicle (402, 600) for detecting an image (204, 214) of a road surface (104, 306, 410, 510) and for generating image data corresponding to the detected image (204, 214). An image processor (118) processes image data of successive images (204, 214) of the road surface (104, 306, 410, 510) detected by the at least one optical detector (102, 300, 404, 406, 500, 602, 604, 606, 608) as the vehicle (402, 600) travels along the road for determining positional change of the vehicle (402, 600) relative to the road surface (104, 306, 410, 510) and for generating vehicle motion data. The optical vehicle motion detection system can be incorporated in a vehicle navigation system (700) to permit monitoring of the movement of the vehicle (402, 600) for accident prevention, traffic control and for other purposes.
