实景三维技术在水库消落区建模分析中的应用探究

Application of Real Scene 3D Technology in Modeling of Reservoir Drawdown Area

论文运用无人机实景三维测绘技术,通过在不同时间节点建立水库库岸实景三维模型,针对水库库水面、库岸边坡、库周泥沙淤积等变化状态进行对比分析,以达到对水库消落区动态监测的目的。从而为防范水库水面持续减少、加强库周边坡稳定、泥沙淤积预警等工作提供基础数据,为消落区库岸治理提供可靠的依据。

In this paper,the UAV real 3D mapping technology is used to establish a 3D model of the reservoir bank at different time.The changes of the reservoir water surface,the reservoir bank slope and the siltation around the reservoir are compared and analyzed to achieve the purpose of dynamic monitoring of the reservoir.It provides basic data for preventing the continuous decrease of reservoir water surface,strengthening the stability of the slope around the reservoir and the early warning of sediment deposition,and provides reliable basis for the management of the reservoir bank in the drawdown area.
