基于多源数据的小型水库库容计算分析

Calculation and Analysis of Small Reservoir Capacity Based on Multi-source Data

采用无人机倾斜摄影测量、机载激光雷达测量、无人船水下测量获取水上水下数据,将多源数据融合,保证了点的精度和密度,得到高精度DEM和等高线地形图。采用DEM方格网法和等高线容积法两种方法对算库容曲线,经检验准确可靠,具有较大的推广应用价值。

UAV oblique photogrammetry,airborne lidar measurement,and unmanned ship underwater measurement are used to obtain above and below water data,and multi-source data are integrated to ensure the accuracy and density of points.Contour lines and high-precision DEM were obtained.The contour volume method and the DEM grid method were used to calculate the storage capacity curve.It has been verified to be accurate and reliable,and has great promotion and application value.
