Application of Low-altitude Unmanned Aerial Vehicle Three-dimensional Oblique Photography Technology in Surveying and Mapping Large-Scale Topographic Maps

大比例尺地形图具备精度要求高、数据精密等特点,如果采取常规的测绘技术容易出现实时数据偏差与数据失真等问题。为解决大比例尺地形图测绘存在的这种问题,本文以某1∶1000测绘工程项目为例,采用低空无人机三维倾斜摄影技术进行大比例尺地形图工作。分析结果表明,通过规范执行低空无人机三维倾斜摄影技术操作流程,得出在测绘大比例尺地形图方面具有实际应用效果,可为推动测绘技术的发展和进步提供理论和实践支持。

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.
