Application of Low-altitude Unmanned Aerial Vehicle Three-dimensional Oblique Photography Technology in Surveying and Mapping Large-Scale Topographic Maps
Large-scale topographic maps have the characteristics of high accuracy requirements and precise data,and the use of conventional surveying and mapping technology may cause real-time data deviation and data distortion problems.In order to solve this problem of large-scale topographic map surveying and mapping,this paper takes a 1:1000 surveying and mapping project as an example,and uses low-altitude unmanned aerial vehicle three-dimensional oblique photography technology for large-scale topographic map.The analysis results show that,by standardizing the operation process of low-altitude unmanned aerial vehicle three-dimensional oblique photography technology,it is concluded that this technology has practical application effects in surveying and mapping large-scale topographic maps,which can provide theoretical and practical support for promoting the development and progress of surveying and mapping technology.
