摘要
Abstract
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.关键词
