无人机低空摄影测量技术在水利工程测量中的应用探究

Application of UAV Low-Altitude Photogrammetry Technology in Hydraulic Engineering Survey

无人机低空摄影测量技术主要是指无人机设备在航高低于1000m的作业条件下进行航空摄影及测量活动,可被应用到文物保护与考古、三维城市建模、地形图更新、灾害应急测绘等多个领域中,在水利工程领域也有良好的使用效果。本文首先分析了无人机低空摄影测量技术的构成与特点,然后分析了将其运用到水利工程测量项目中的关键要点,以期为水利工程测量提供参考思路。

UAV low-altitude photogrammetry technology mainly refers to aerial photography and surveying activities carried out by UAV equipment under operating conditions at an altitude of less than 1000 m.It can be applied to cultural relics protection and archaeology,three-dimensional urban modeling,topographic map updating,disaster emergency surveying and mapping,and other fields,and also has good application effects in the field of hydraulic engineering.This paper first analyzes the composition and characteristics of UAV low-altitude photogrammetry technology,and then analyzes the key points of its application to hydraulic engineering survey projects,so as to provide reference ideas for hydraulic engineering survey.
