摘要
为对水库开展库容曲线复核工作,本文以山东省内某中型水库为例,采用四等水准将水库周边高程联测到国家高等级水准点上,再采用无人机低空航摄与无人船水下测量获取水库地形三维空间坐标数据,并生成库区三维模型;借助三维模型绘制库区地形图及等高线,将直接从库区三维模型提取等高线计算的库容,与由库区周边地形点和特征点生成的DEM方格网法计算的库容作对比。结果表明,通过两种方法计算得到的面积和库容基本一致,验证了从模型提取等高线法计算结果的准确性,为水库库容曲线复核提供了技术参考。
In order to carry out the recheck of reservoir capacity curve,this article takes a medium-sized reservoir in Shandong Province as an example.Fourth-grade-leveling survey is used to measure the elevation around the reservoir to the national high-level benchmark.Then,unmanned aerial vehicle low altitude aerial photography and unmanned ship underwater measurement are used to obtain the three-dimensional spatial coordinate data of the reservoir terrain,and a three-dimensional model of the reservoir area is generated.With the help of the 3D model,a topographic map and contour lines of the reservoir area are drawn.The calculated storage capacity directly extracted from the 3D model of the reservoir area is compared with the storage capacity calculated by the DEM grid method generated by the terrain points and feature points around the reservoir area.The results show that the area and storage capacity calculated by the two methods are basically consistent,which verifies the accuracy of the contour line method calculation results extracted from the model and provides technical reference for the review of the reservoir capacity curve.
