Title (EN) SYSTEM FOR MEASURING THE DISTANCE OF AN OBSTACLE BY OPTICAL FLOW
(FR) SYSTÈME DE MESURE DE LA DISTANCE D'UN OBSTACLE PAR FLUX OPTIQUE
Abstract: front page image
(EN) The invention relates to a system for measuring the distance of an obstacle (14), in which an optical flow is radially measured in rotation around a circle (12) 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.
(FR) L'invention est relative à un système de mesure de distance d'un obstacle (14), dans lequel un flux optique est mesuré radialement en rotation sur un cercle (12) dans un plan coupant l'obstacle; et la distance de l'obstacle est déterminée en fonction de l'amplitude du flux optique, du rayon du cercle, et de la vitesse de rotation.
