水陆空三位一体测绘技术在山塘水库库容测绘中的应用

Application of the Trinity Surveying and Mapping Technology of Water,Land and Air in the Capacity of Pool and Reservoir

针对传统水库库容测绘中存在的工作强度大、作业效率低、人员安全风险较高等问题,本文提出了水陆空三位一体测绘新技术。该技术采用智能无人测量船获取水下地形数据,通过无人机倾斜摄影获取陆域地形数据,并结合传统的陆域测绘手段进行补充测量,为倾斜摄影技术提供高精度的像片控制网。三位一体测绘技术结合了无人船测深系统与无人机倾斜摄影技术,实现了山塘水库库容测绘中水域水下地形测绘与陆域地形测绘的无缝接边。本文提出的三位一体测绘技术在山塘水库库容测绘中得到了很好的应用。

In view of the problems existing in traditional reservoir capacity mapping,such as high work intensity,low work efficiency and high risk of personnel safety,this paper puts forward a new technology of water,land and air Trinity mapping.The technology uses intelligent unmanned surveying vessel to obtain underwater topographic data,oblique photography of unmanned aerial vehicle to obtain land topographic data,and supplementary surveying combined with traditional land mapping means to provide high-precision photo control network for oblique photography technology.Trinity mapping technology combines unmanned ship sounding system and UAV tilt photography technology,realizes seamless joint of underwater topographic mapping and land topographic mapping in pool and reservoir reservoir capacity mapping.The Trinity surveying and mapping technology proposed in this paper has been well applied in the reservoir capacity surveying and mapping of pool and reservoir.
