I have been developing a augmented reality 3D Racing Game. I'm planning on doing an AR application that will use GPS and Augmented Reality technologies to get a location, and then use compass/gyroscope for tracking 6DOF viewfinder movements. By merging the real world and the game world, augmented reality helps you discover a new way to play........Your racing track is populated with 3D interactive characters and scenarios.
But my question is how to use any vision processing(relying on GPS), and to display 3d models on the screen at roughly correct distances (up to a point) from where the car is positioning.

GPS is not nearly precise on it's own. You need to place visual markers (like the ones on test dummies) along the track for fine tuning. My 3D reconstruction project in image analysis showed that the points need to be using around 45 degree field of view before you can get a good enough estimation of the camera's location. You will also need to smooth the camera position to avoid shaking. Anything large on the CPU will make it too slow for realtime use.
