SYSTEM FOR MEASURING THE DISTANCE OF AN OBSTACLE BY OPTICAL FLOW

The invention relates to a system for measuring the distance of an obstacle (14), wherein 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 rad...

More Information
Summary:The invention relates to a system for measuring the distance of an obstacle (14), wherein 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. 本发明涉及一种用于测量障碍物(14)的距离的系统，其中在沿着与障碍物相交的平面中的圆周(12)旋转的同时径向测量光流；并且根据光流的幅度、圆周的半径和旋转速度确定障碍物的距离。
