Abstract
A system and method for video navigation are disclosed. Motion analysis can be performed upon camera images to determine movement of a vehicle, and consequently present position of the vehicle. Feature points can be identified upon a video image. Movement of the feature points between video frames is indicative of movement of the vehicle. Video navigation can be used, for example, in those instances wherein GPS navigation is unavailable.
