空天库岸一体化应急勘测系统及其在库岸滑坡调查中的应用

Integrated emergency survey system and its application in landslide investigation

通过将多源勘测系统进行集成构建了空天库岸一体化应急勘测系统,然后基于点云数据融合以及NURBS曲面重建的理论,开发了系统软件部分,最后以呷爬滑坡为例,对滑坡进行三维场景建模,同时展示了无人机水上航拍、多波束水下滑坡以及ROV拍照的效果图。结果表明,本研究提出的空天库岸一体化应急勘测系统可用于现场滑坡体应急抢险的前期勘察、水库边坡的长期监控以及水利水电工程中的常规测绘及地质调查,具有快速、高效、高精度、低成本等特点,在水利水电工程中具有广泛的应用前景。

The multi-source survey system is integrated to construct an integrated emergency survey sys?tem.Then based on the theory of point cloud data fusion and NURBS surface reconstruction,the system software is developed.Finally,taking the Xiapa landslide as an example,the renderings of drone aerial photography,multi-beam water gliding and ROV photography are also showed.The experimental results show that the integrated emergency survey system proposed in this study can be used for the early inves?tigation for on-site landslide emergency rescue,the long-term monitoring of reservoir slopes,and the conventional surveying and geological survey in water conservancy and hydropower projects.It is of high efficiency,high precision,low cost and has broad application prospects in water conservancy and hydro?power projects.
