The invention relates to the technical field of topographic surveying and mapping, and discloses an unmanned aerial vehicle-based three-dimensional topographic surveying and mapping device, which comprises an unmanned aerial vehicle aircraft, a topographic surveying and mapping mechanism is arranged at the bottom of the unmanned aerial vehicle aircraft, and the topographic surveying and mapping mechanism comprises a mounting box, a surveying and mapping assembly and an auxiliary assembly, a mirror surface of the laser range finder and a mirror surface of the camera are embedded in the front end of the equipment shell, the terrain surveying and mapping mechanism is driven by the unmanned aerial vehicle to fly in the sky, a motor is started to drive a first rotating rod to rotate, and then a piston rod is driven to do linear reciprocating motion on the inner side of an air conveying pipe; and then a piston rod continuously extrudes the dehumidified cold air in the air conveying pipe in a reciprocating manner, and then a spraying plate continuously sprays the dehumidified cold air, so that continuous heat dissipation treatment on electronic elements in a laser range finder and a camera working in the equipment shell is realized, and the accuracy of surveying and mapping data and stable operation of the equipment are ensured.

    本发明涉及地形测绘技术领域,并公开了一种基于无人机的三维地形测绘装置,包括无人机飞行器,无人机飞行器的底部设置有地形测绘机构,地形测绘机构包括安装箱、测绘组件、辅助组件,激光测距仪的镜面和相机的镜面均嵌入安装在设备壳体的前端,通过无人机飞行器带动地形测绘机构在天空中飞行,启动电机带动转杆一进行转动,进而带动活塞杆在输气管的内侧做直线往复运动,进而使活塞杆不断往复挤压输气管内的除湿后的冷空气,进而使喷洒板不断喷出除湿后的冷空气,实现了持续对设备壳体内工作的激光测距仪、相机中的电子元件进行散热处理,保证了测绘数据的准确性和设备的稳定运行。
