无人机倾斜摄影技术在大比例尺地形图测绘中的应用

The Application of Unmanned Aerial Vehicle Oblique Photography Technique in Large Scale Topographic Mapping

利用低空无人机倾斜摄影技术快速获取多角度影像数据,通过自动实景三维建模和三维模型立体量测技术,从而实现免外业调绘的高精度大比例尺地形图测绘。本文通过具体生产实验,详细介绍基于无人机倾斜摄影测量技术的大比例尺地形图作业流程,并通过精度分析,验证了此方法的可行性。

Using the low-altitude UAV oblique photography technology to quickly obtain multi-angle image data,through the automatic three-dimensional modeling and three-dimensional model of three-dimensional measurement technology,in order to achieve the large-scale topographic mapping of high-precision without surveying.The paper introduces in detail the workflow of large-scale topographic mapping based on UAV oblique photography technique through special production experiments,and verifies the feasibility of the method with precision analysis.
