无人机倾斜摄影及三维建模技术在地质灾害应急测绘中的应用

Application of UAV tilt photography and 3D modeling technology in geological disaster emergency mapping

无人机倾斜摄影测量具有成本低廉、灵活高效的优点,基于无人机倾斜摄影技术构建的三维模型已得到广泛应用。本文通过无人机搭载的倾斜相机采集数据,用三维建模软件处理数据,得到地质灾害发生区域的三维信息,可为应急救灾提供定量和定性数据分析服务。

UAV tilt photogrammetry has the advantages of low cost,flexibility and high efficiency,and the 3D model based on UAV tilt photogrammetry technology has been widely used.In this paper,the tilt camera carried by UAV is used to collect data,and the 3D modeling software is used to process the data to obtain the 3D information of the geological disaster area,which can provide quantitative and qualitative data analysis services for emergency relief.
