The Influence And Analysis Of The Accuracy Of Large-scale Topographic Map Of UAV(ZC-1)

Since 1930s,the UAV has experienced 90 years of development history.The rapid development of space science and technology,the application of UAV has been extended and developed in surveying and mapping industry.In recent years,the UAV aerial photogrammetry system has become a new development direction in the field of aerial photogrammetry.With the development and improvement of the UAV photogrammetry technology,there are more and more applications in surveying and mapping.However,there are still a lot of problems to be solved when the UAV is mapping large scale topographic map.Due to the lack of relevant standards about UAS,there are some problems in the operations,such as the scheme is not clear,the accuracy is not stable and so on.This paper takes the existing UAV aerial camera system as the research object,it firstly introduces the development of UAS.research status,related basic theory,working methods and so on.In this study,the 1:1000 Sha Yuan area and the 1:2000 Yuan Zi gou area are selected as the experimental area,and the method of improving the accuracy of the large scale topographic map of the UAV is studied.In this study,the 1:1000 Sha Yuan area and the 1:2000 Yuan Zi gou area are selected as the experimental areas to study the method of improving the accuracy of the large scale topographic map.This paper studies the influence factors of the accuracy of aerial mapping topographic map by ZC-1 uav,aerial photography,from outside the industry,like the empty three encryption and stereo mapping to analyze factors affecting the accuracy of each stage.Secondly,select 1:1000 Sha Yuan area and the 1:2000 Yuan Zi gou area as the experimental area,and study how the layout scheme of control Points effect on the accuracy from the empty three encryption,And then carry on the proof to the experimental results by the Yin chuan project and Feng jia ta coal mine project.both meet the requirements of specification.Finally,a new method is provided for improving the accuracy of aerial aerial surve...
