植保无人机避障技术研究

植保无人机避障技术研究摘要由于我们国家的耕地面积过大，单纯的利用人力对农药等进行喷酒的难度过大，所以需要利用无人机进行此项工作。但是，国内适用的大部分无人机存在避障能力弱的问题，该问题的存在导致无人机容易出现碰撞、炸机等问题。因此，本文对植保无人机的避障技术进行深入研究。关键词：植保无人机：避障技术：优化设计ABSTRACTDue to the large area of cultivated land in our country,it is too difficult to spraypesticides simply by manpower,so UAVs need to be used for this work.However,most UAVs applicable in China have the problem of weak obstacle avoidance ability,which leads to the problems of collision and aircraft explosion.Therefore,theobstacle avoidance technology of plant protection UAV is deeply studied in this paper.Key words:plant protection UAV;Obstacle avoidance technology;optimaldesign目录摘要.ABSTRACT...........2第一章绪论.…4第二章障碍物检测方法..·42.1毫米波雷达原理....2.2障碍物检测......2.2.1前方测距...52.2.2侧方测距....2.2.3宽度检测....第三章植保无人机避障系统设计.63.1系统框架..…63.2主要元器件设计.....73.2.1毫米波雷达..73.2.2嵌入式处理器..73.2.3传感器安装.73.2.4运算处理模块设计..83.2.5避障绕飞....9第四章结论..10参考文献..12
