Abstract: A lane tracking system for a vehicle employing redundant imaging devices with different fields of view is disclosed. The imaging devices are oriented in generally opposite directions so glare or other harsh lighting hampering one imaging device will not affect the other device. The appropriate image is selected based on image quality and used to detect lane markers and vehicle position. A preferred application for lane departure warning is also disclosed.
