摘要
无人机倾斜摄影实景三维建模技术为大比例尺地形图更新测绘提供了新的技术方案。以淳安县1:500大比例尺地形图更新项目为实例,首先介绍了无人机实景三维建模技术以及基于该技术进行地形图更新测绘的作业流程,然后对作业中的关键技术进行阐述,最后采用野外实地采集的检查点对技术方案生产的数字地形图精度进行检测。检测结果表明该方案能够满足1:500地形图更新的精度要求,可以为同类项目生产提供参考。
The rapid development of unmanned aerial vehicle(UAV)oblique photography real-time 3D modeling technology provides a new technical solution for updating and surveying large-scale topographic maps.This article takes the 1∶500 large-scale topographic map updating project in Chun’an County as an example.Firstly,it introduces the UAV real-time 3D modeling technology and the operation process of topographic map updating and surveying based on this technology.Then,the key technologies in the operation are explained.Finally,the accuracy of the digital topographic map produced in this article is tested using inspection points collected in the field.The detection results indicate that the scheme can meet the accuracy requirements of 1∶500 topographic map update and can provide reference for similar project production.
