摘要
数字孪生技术是当前数字中国建设的重要支撑之一,其研究与应用成为各领域的热点方向。开源三维地图框架Cesium支持多源多维度的数据集成可视化,面对数字孪生在统一数字空间内的一体化展示需求,文章围绕Cesium支持的数据类型和数字孪生的数据融合需求,通过多源数据处理和融合可视化的关键技术研究,实现了影像、地形、矢量要素和三维模型数据常用格式面向Cesium的数据转换和融合集成管理,并以某水利工程场景为实例验证了方法的适用性。
Digital twin technology is one of the important supports for the construction of digital China,its research and application have become a hot topic in various fields.Cesium is an open source three-dimensional map framework that supports multi-source and multi-dimensional data integration visualization.Faced with the integrated display requirements of digital twin in a unified digital space,this paper focuses on the data types supported by Cesium and the data fusion requirements of digital twin.According to the key technologies research of multi-source data processing and fusion visualization,the Cesium-oriented data conversion and fusion integration management of common data formats such as image,terrain,vector elements and 3D models are realized,and a water conservancy project scene has been selected as the application example to verify the applicability of the method.
