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