The invention relates to the technical field of laser point cloud acquisition, and provides an unmanned aerial vehicle point cloud data scanning implementation method and system in a raining environment. The first unmanned aerial vehicle and the second unmanned aerial vehicle obtain positioning information and space size information of a to-be-scanned target object; the current falling angle of the rain is obtained, and the falling angle of the rain is obtained through calculation according to the collected wind direction, wind power and rainfall; according to the falling angle and the height of the to-be-scanned target object, setting one-stage or multi-stage scanning layers in the first group; and generating point cloud data of the target object according to the scanning data of the first unmanned aerial vehicle and the second unmanned aerial vehicle. According to the invention, it is fully excavated that rain seems irregular, the rain in a small-range area actually comes from clouds in the same area with a large probability, and the falling time of the rain from the air has regularity with a certain probability, that is, a layering area with certain raindrop interference exists; the scanning method corresponding to the first unmanned aerial vehicle is set according to the technical characteristic.

    本发明涉及激光点云采集技术领域,提供了一种下雨环境下无人机点云数据扫描实现方法和系统。第一无人机和第二无人机获取待扫描目标对象的定位信息和空间大小信息;获取当前的雨的飘落角度,其中,雨的飘落角度是根据采集到的风向、风力和雨量计算得到;根据飘落角度和待扫描目标对象的高度,设定出第一组内的一级或者多级扫描层;依据第一无人机和第二无人机的扫描数据生成目标对象的点云数据。本发明充分挖掘了下雨看似无规律,实则在小范围片区内的雨实则较大概率是来自同一片区的云,而他们从空中下落时机存在一定概率的规律性,即存在一定雨滴干扰的分层区,而本发明则是抓住了这一技术特性设定了相应第一无人机的扫描方法。
