一种基于激光雷达技术的水库库容计算方法
|
摘要
快速准确计算水库库容,对水库水情管理和防洪监测具有重要意义。利用遥感和GIS技术,基于Skyline平台,以新立城水库为例,提出了一种基于像元的三维水面库容计算方法。该方法利用激光雷达技术获取水下地形,利用空间技术获得三维水面,并通过库容计算模型得到水库库容。结果表明,该方法大大提高了工作效率和数据精度,为大范围应用提供了支持。
Based on Skyline platform, taking the Xinlicheng reservoir for example, we used remote sensing and GIS technology to set up a 3D surface capacity calculation method based on pixel. The method used the Li DAR technology to get the underwater terrain, and used spatial technology to get 3D surface. And then, the method got the result by capacity calculation model. The result shows that this method can greatly improve the work efficiency and data accuracy, and provide a support for the wide range application.
