摘要:
针对灌区三维虚拟场景构建的多源异构数据,提出了支持灌区水工建筑物三维模型(BIM)与三维虚拟地理场景模型(3D GIS)构建数据采集总体技术路线与技术方法; 从宏观尺度灌区地理场景与微观尺度水利设施内部场景可视化2个方面研究了三维虚拟地理场景构建方法; 对涉及的基于Cesium的地理场景高效渲染、三维地形模型与水利工程模型无缝融合、水系线性要素空间建模、闸口等点状物建模、水文要素的动态渲染、多尺度模型加载关键技术问题提出了解决方案。根据淮阴竹络坝灌区的特点,采用了“GIS+BIM”融合模式构建了灌区三维虚拟地理场景,为数字灌区建设奠定了基础。
Abstract:
Aiming at the multi-source heterogeneous data of three-dimensional virtual scene construction in irrigation area,the overall technical route and method of data acquisition supporting three-dimensional model of hydraulic structures( BIM )and three-dimensional virtual geographic scene model( 3D GIS )in irrigation area were proposed. The construction method of 3D virtual geographic scene was studied from two aspects of the macro scale geographica scene of irrigation area and the micro scale internal scene visualization of water conservancy facilities. The solutions to the key technical problems involved in efficient rendering of geographic scene based on Cesium,3d terrain model and hydraulic engineering model,spatial modeling of linear elements of river system,modeling of point objects such as sluicing gates,dynamic rendering of hydrological elements,and loading of multi-scale model were proposed. According to the characteristics of Zhuluoba Irrigation Area in Huaiyin Distric,the "GIS+BIM" fusion mode was used to construct the 3D virtual geographic scene of irrigation area,which laid a foundation for the construction of digital irrigation area.
