In this paper, we propose a method for image overlay on the front glass of a vehicle to navigate a driver to a desired destination. By overlaying the navigation imformation on the front glass, the driver need not gaze at the console panel. Therefore, accidents caused by gazing at console panel could be reduced. To overlay the image accurately on the target object through the front glass, both the vehicle’s position/orientation and the driver’s position/orientation are estimated by vision-based tracking and measuring angular velocities of the vehicle’s wheels. Experimental results show the validity of the proposed method.
