Time-to-collision from first-order models of the motion field

Time-to-collision provides vital information for obstacle avoidance and for the visual navigation of a robot. The original contribution of this paper is to demonstrate with sequences of real images that time-to-collision can be robustly and accurately recovered with a single calibrated camera, using first order models of the motion field. >
