Working with technology used in the 2005 DARPA Grand Challenge, Subaru is trying to give its cars sight. A display at Subaru's 2007 Geneva auto show booth shows how two cameras can produce stereo-optic vision, which can be processed to show how far objects are away from the car. In the demonstration, the single image processed from the two cameras identifies people and other cars and uses a color coding system to show how far they away they are. If this system were deployed in a car, the car could let the driver know if he or she is about to hit a pedestrian or a less movable object. Or the car could just hit the brakes for the driver, all depending on how intrusively the system is designed. Subaru has no plans to deploy the system any time soon--the display just lets the world know the company has the technology.
