数字孪生流域可视化技术研究与实践

Discussion and practice on visualization technology ofdigital twin watershed

当前数字孪生流域作为智慧水利体系建设的核心,正在水利行业大力推进。数字孪生旨在高保真、高质量还原流域复杂的现实场景,实现多源、多维度、多粒度水利数据的空间表达与计算分析,动态实时感知现实世界。为了探讨可视化与数字孪生流域内在联系及其视觉效果,从数据可视化、三维仿真模拟及知识图谱3个方面对数字孪生流域可视化关键技术进行研究,并验证其应用的可行性,结果表明:可视化能够为数字孪生提供直观的数据或场景,降低对孪生实体管理的复杂度。

At present,the construction of digital twin watershed,as the core of the construction of intelligent water conservancy system,is being vigorously promoted in the water conservancy industry.The aim of digital twin is to restore complex real-world scenarios of watersheds with high fidelity and high quality,realize spatial expression and computational analysis of multi-source,multi-dimensional and multi-granularity water conservancy data,and dynamically perceive the real world in real time.In order to explore the internal relationship between visualization and digital twin watershed and its visual effect,this paper studied the key technologies of digital twin watershed visualization from three aspects:data visualization,3D simulation and knowledge map,and verified the feasibility of its application.The results show that visualization can provide data or scenes for digital twinning and reduce the complexity of managing twin entities.
