摘要
激光雷达是地球大气探测的有利工具,但其向空中发射的强激光束会对空域飞行物存在潜在威胁。为保障激光雷达上空飞行物的飞行安全, 提出了一种基于CCD成像探测的激光智能主动规避飞行物的方法, 并搭建了一套实验装置。该装置通过触发同步控制CCD实时采集激光雷达激光束方向一定范围的空域图像, 再对图像进行降噪、差值和二值化等处理, 并判断是否有飞行物在空域范围内, 根据处理结果控制激光发射光路中的机械开关打开或者关闭, 有效保证了激光雷达的安全运行以及飞行物的安全。
Abstract
Lidars emit high intensity of laser beam to the sky, which has a potential threat to the flyers. For the flight safety and the safe operation of lidar, a method was proposed for laser actively evading flying objects and an experimental setup was built up. The system utilized a CCD to achieve image acquisition of the airspace around the lidar emitting beam in real time. The images were transmitted to the PC and processed by the control software. Finally the shutter in the lidar emitting path was controlled to turn on or turn off according to the results of the imaging process. When flyers fly into the field of view of the CCD, the shutter can be turned off automatically to cut off the laser emission path so that to ensure the flight safety and the safe operation of lidar.
