Application of remote sensing by unmanned aerial vehicle in the small-field engineering surveying

介绍低空无人机遥感的特点及其应用现状,分析在小范围工程测绘的应用优势。根据实践:论述无人机遥感数据处理的基本流程以及一些关键技术,并对其精度进行分析;论证了其在工程测绘中的可行性。最后,对低空无人机遥感在测绘中的应用趋势及有待进一步解决的问题进行了探讨。

This paper introduces features and the application of UAV photogrammetry,which is competitive in the small- field engineering surveying. Based on practical experiments,the paper,furthermore,explains the basic data process of UAV remote sensing and some relative technologies. And the data accuracy is also testified,which proves that it is feasible to be applied in engineering surveying. Finally the paper makes a further discussion on its application trends and possible problems.
