大疆精灵系列无人机在大比例尺地形图快速成图中的应用

Application of DJI Elf Series UAVs in Rapid Mapping of Large-scale Topographic Maps

无人机测绘主要是通过无人机对目标区域进行航空摄影,然后利用配套航测数据处理系统,对航拍影像数据进行有效处理,制作出特定区域的数字正射影像图、数字地形图等。而大疆精灵系列无人机具有小巧轻便、性能稳定、易上手的特点,可以进行高精度航拍。本文将大疆精灵4 Pro无人机应用于某地形图成图项目中,有效缩短了项目作业时间,充分减轻测量外业工作强度,有效提高了作业效率,在项目实践中得到了较好的应用。

UAV surveying and mapping mainly uses aerial photography of target areas through UAV,and then uses the supporting aerial survey data processing system to effectively process aerial image data to produce digital orthophoto maps and digital topographic maps of specific areas.The DJI Elf series UAV has the characteristics of small and light,stable performance,easy to use,and can perform high-precision aerial photography.This article applies the DJI 4 Pro UAV to a topographic map mapping project,which effectively shortens the project operation time,fully reduces the measurement field work intensity,effectively improves the operation efficiency,and has been better applied in project practice.
