摘　　要：无人机倾斜测量技术应用于大比例尺地形图绘制中不仅可以提高工作效率、节约人力物力成本,更能克服人工测量受地形限制的不足。为了探究无人机倾斜摄影测量多个维度精度,在无人机航测系统基本原理分析基础上,研究了航测系统误差来源和误差评定标准,通过以某村庄航空摄影测量进行试验,对无人机倾斜测量的点位精度、高程精度、长度精度和面积精度进行了系统分析。结果表明:无人机倾斜测量的多个维度精度均满足要求,该技术方法适用于大比例尺地形图绘制。The application of UAV tilt photogrammetry technology in large-scale topographic map drawing can not only improve work efficiency,save manpower and material costs,but also overcome the shortcomings of manual measurement limited by terrain.In order to plumb the multi-dimensional accuracy of UAV tilt photogrammetry,based on the analysis of the basic principle of UAV aerial survey system,the error source and error evaluation standard of aerial survey system are studied.Through the experiment of aerial photogrammetry in a village,the point accuracy,elevation accuracy,length accuracy and area accuracy of UAV tilt photogrammetry are systematically analyzed.The results show that the multi-dimensional accuracy of UAV tilt photogrammetry meets the requirements,and the technical method is suitable for large-scale topographic map drawing.
