无人机摄影测量及数据处理技术在地质灾害应急调查中的应用——以娄底市娄星区杉山镇同安村滑坡为例

Application of UAV Photogrammetry and Data Processing Technology in Geological Disaster Emergency Investigation——Taking the landslide of Tong’an village, Shanshan Town, Louxing District, Loudi City as an example

本文利用大疆精灵4RTK无人机,对娄底市娄星区杉山镇同安村一处滑坡地质灾害进行摄影测量,拍摄的照片并采用Pix4dmapper软件进行影像数据处理,生成滑坡区域正射影像图和三维模型,在此成果数据基础上进行测量、分析、研判,查明了滑坡的基本特征,划定了滑坡地质灾害危险区,为政府防灾减灾、保障人民群众生命财产安全提供科学依据,用以保障人民群众生命财产安全。

In this paper,DJ phantom 4 RTK UAV was used to photograph and measure the landslide happening in the Tongan village,Loudi City,Hunan Province.The photographs were processed by Pix4dapper software to generate DOM and 3D models of the landslide area.The basic characteristics of the landslide are found out through measurement,analysis and study with result data.And also the geological hazard area is determined,which provides scientific basis for the government to prevent and reduce disasters and ensure people's lives and property safety.
