Abstract
Lee's Time-to-Contact theory can be exploited to design simple, low-resolution optical sensors for robotics. An optical collision timer yields a direct measure of the safe time margin when approaching an object along the camera axis. This is achieved by timing the rate of image expansion ( looming ). This paper describes the Time-to-Contact paradigm, explores a family of architectures for coping with a variety of imaging conditions and concludes with a graphical simulation.
