无人机倾斜摄影在地质灾害三维可视化中的应用

摘要

Oblique photogrammetry of UAV is a new technology in photogrammetry.It is a hot spot of research at home and abroad.Combined with practical work,this paper makes a feasibility study on the application of obliquePhotogrammetry in the construction of 3D model of geological hazard.In order to realize the 3D visualization analysis,including safety assessment,disaster development and impact simulation,we try to provide technical and decision support for disaster prevention and mitigation.%无人机倾斜摄影测量是摄影测量学科中的新兴技术,是目前国内外研究的热点.结合实际工作,对无人机倾斜摄影测量在地质灾害三维可视化模型构建中的应用进行可行性研究,为快速实现地质灾害三维可视化分析、安全性评估以及灾害发展与影响模拟,建立地质灾害模拟预警系统等防灾减灾工作提供技术和决策支持.
