无人机遥感数据支持下滑坡VR场景探索分析方法
|
摘要
滑坡灾害是最常见的地质灾害之一,无人机遥感和虚拟现实(virtual reality,VR)技术的快速发展为滑坡灾害沉浸式模拟与可视化分析提供了重要的数据资源和技术支持。拟重点开展滑坡灾害VR场景动态构建与探索分析研究,探讨了滑坡灾害数据多样化组织、VR场景动态融合表达等关键技术,提出了基于手柄射线的VR场景交互方法,在此基础上进行了原型系统研发与案例试验分析。试验结果表明,所提方法在无人机遥感数据支持下能够动态构建滑坡灾害VR场景,并且能够支持用户沉浸式交互与滑坡灾情信息分析。
The landslide is one of the most common geological hazards in nature, the rapid development of unmanned aerial vehicle(UAV) technology and virtual reality(VR) technology provides important data resources and technical support for immersive simulation and visual analysis of the landslide. Firstly, this paper focuses on the dynamic construction and exploratory analysis of VR scene in landslide hazard, then some key technologies such as diversified organization of landslide data, dynamic fusion visualization of VR scene are addressed in detail, thus a VR scene interaction method based on handle ray is proposed. Finally, a prototype system is implemented and a case study region is selected for experimental analysis. The experimental results show that the proposed method can dynamically construct landslide VR scene based on UAV remote sensing data, and can support the user to carry out immersive interaction and disaster information analysis.
