无人机三维建模在地质调查中的应用研究

Application of UAV 3D modeling in geological survey

地质调查能够提供地形地貌、岩性、构造以及危险地质点源等诸多信息,对经济社会的发展与安全稳定起到基础性又关键性的支持保障作用,是一项周期性且任务量浩繁的工作。本文针对地质调查的特点及需求,充分运用当前已日益成熟的无人机倾斜摄影和三维建模技术,提出一种基于无人机三维建模的地质调查手段,对研究区域的地质点、线、面、体等信息进行采集及分析,并开展综合地质研究,力求在地质调查工作量越来越大的当前,构建一种高效率、低成本、易普及的调查方式,提高地质调查的速度和精度。

Geological survey can provide a lot of information such as landform,lithology,structure and dangerous geological point sources,and plays a basic but key supporting and ensuring role for economic and social development,security and stability.It is a periodic and heavy task.According to the characteristics and requirements of geological survey,this paper makes full use of the increasingly mature UAV tilt photography and three-dimensional modeling technology,puts forward a geological survey method based on UAV three-dimensional modeling,collects and analyzes the geological point,line,surface,body and other information in the study area,and strives to overcome the increasing workload of geological survey,to build a survey method with high efficiency,low cost and easy popularization,so as to improve the speed and accuracy of geological survey.
