摘要
针对珠江流域关键控制性工程——大藤峡水利枢纽在数字孪生建设中对高精度三维模型的迫切需求,该研究提出一套融合无人机倾斜摄影测量、人工重建单体化及多源空间数据集成的技术体系。通过五镜头无人机航摄构建实景模型,基于多视影像几何约束结合DP-Modeler工具实现水工建筑物轮廓精准提取,经人工编辑构建单体模型,并挂接属性实现“一物一码”管理;进而通过坐标精准转换、地形数据清洗及三维场景融合技术,构建与物理实体动态映射的可更新数据底板。该文以大藤峡水利枢纽为例,系统阐述多源空间数据集成的技术流程与方法,可为数字孪生流域空间数据底板建设提供范式参考。
In response to the urgent need for high-precision three-dimensional models in the construction of digital twins,the Datengxia Water Conservancy Project,a key control project in the Pearl River Basin,this study proposes a set of integrated UAV oblique photogrammetry,manual reconstruction monomerization and multi-source spatial data.Technical system.A real-life model is constructed through five-lens UAV aerial photography,based on multi-view image geometric constraints combined with DP-Modeler tools,the single model is constructed through manual editing,and attributes are connected to achieve"one object,one code"management;and then an updatable data backplane that dynamically maps with physical entities is built through precise coordinate conversion,terrain data cleaning and three-dimensional scene fusion technologies.Taking the Datengxia Water Conservancy Project as an example,this paper systematically expounds the technical process and methods of multi-source spatial data integration,which can provide a paradigm reference for the construction of digital twin river basins spatial data backplane.
