无人机技术在大比例尺地形图测量中的应用研究

Research on the Application of Drone Technology in Large Scale Topographic Map Measurement

基于大疆精灵4 RTK多旋翼无人机、GPS-RTK(GPS-Realtime kinematic)实时动态载波相位差分技术等软硬件设备,对选矿厂区地形图、地图空间元素作出测量绘制,按照1∶500比例采集区域范围内的建筑、基础设施、绿化景观排布信息,从而解决无人机航空摄影的成像曝光延迟、定位精度不高等问题。

Based on software and hardware equipment such as DJI Elf 4 RTK multi rotor unmanned aerial vehicle and GPS-RTK(GPS-Realtime Kinematic)real-time dynamic carrier phase difference technology,the topographic map and spatial elements of the ore dressing plant area were measured and drawn.The building,infrastructure,and green landscape layout information within the area was collected at a ratio of 1∶500,thus solving the problems of imaging exposure delay and low positioning accuracy in drone aerial photography.
