摘要
为了更加系统、全面地从无人机航拍资料中提取相关地质信息,让无人机更好地服务于地质调查工作。本文研究了利用无人机航拍影像资料进行地质宏观分析的思路以及基于三维彩色数字地面模型进行地质点、线、面、体等信息获取的工作流程,同时形成了一套利用无人机进行辅助地质调查工作的技术方法。通过在滑坡灾害地质调查实际工作中的具体应用验证了基于无人机辅助开展地质调查工作的可行性和高效性。该方法对如何基于无人机航空地质测绘进行全面系统地质资料的有效获取和地质综合调查具有一定指导意义。
This paper aims to systematically and comprehensively extract relevant geological information from UAV aerial photography data and ensure that it can better assist in geological survey work.It introduces the method of geologic overall analysis and information acquisition of geological points,boundary,plane,objects based on photos and DEM made by UAV.At the same time,it forms a set of technical methods for assisting geological survey with UAV.It verifies the feasibility and efficiency of UAV in geological survey work through practical application in geological survey of landslide disaster.The study has certain guiding significance for effective acquisition of comprehensive and systematic geological data based on UAV aerial geological mapping and geological comprehensive survey.
