面向虚幻引擎的水利工程多源数据转化融合技术初探

Exploration of multi-source data transformation and fusion technology for hydraulic engineering in Unreal Engine

摘要:

随着数字孪生流域和工程在水利行业的提出，对模拟仿真引擎的多源数据承载、兼容、渲染、模拟仿真等能力的要求逐渐提升。为解决数据底板中多源数据融合和高保真场景构建的难题，创新性地在水利行业提出一种基于虚幻引擎（UE）的多源数据底板建设方案，可将体形复杂、体量较大的水利行业主流 BIM 设计平台（尤其是 3DE平台）的设计模型，转换为轻量化、美观的展示模型，并导入 UE 平台中形成高保真工程数字孪生场景，最终研发九峰山抽水蓄能电站可研数字汇报系统，并用于项目可研汇报；系统运行顺畅，展示效果好，表明技术路线可靠、可行，可为数字孪生工程的实现提供参考。

Abstract:

With the advent of digital twin basins and projects in the water conservancy industry，the requirements of multisourcedata handling，compatibility，rendering，and simulation capabilities of simulation engines are gradually increasing.An innovative multi-source data baseplate construction scheme based on Unreal Engine（ UE） is proposed in order toaddress the challenges of multi-source data fusion and high-fidelity scenario construction，in which complex and largescaleBIM models from mainstream hydraulic engineering design platforms（ particular the 3DExperience platform） can betransformed perfectly into lightweight and visually appealing display model. The model is imported into the UE platformto create high fidelity digital twin scenarios，and finally the Jiufengshan pumped storage power station research digitalreporting system is developed，which is applied in the project research report and demonstrates good system performanceand reliable technique routine，thereby providing a valuable reference for the implementation of digital twin projects.
