Abstract:
A system for measuring the distance of an obstacle, in which an optical flow is measured radially while rotating along a circle in a plane intersecting the obstacle; and the distance of the obstacle is determined according to the amplitude of the optical flow, the radius of the circle, and the speed of rotation.
