摘要
针对航电枢纽施工动态管理的特点,基于数字地形构建原理,运用CityEngine技术,构建航电枢纽研究区段的数字地形和三维水工建筑物,提出三维场景融合方法。基于ArcSDE+SQL Server空间数据库技术,以内部代码和用户标识码为公共数据项,将属性数据与空间数据进行连接,建立三维场景动态展示方法,完成航电枢纽施工过程三维动态可视化仿真,设计工程施工三维动态展示与施工过程信息同步更新机制,实现航电枢纽施工动态可视化管理。基于建立的系统功能框架,以依兰航电枢纽施工管理为例,开发施工动态三维可视化管理系统,为航电枢纽工程施工可视化、精细化管理提供技术支持。
In view of the characteristics of the dynamic management for the navigation-power junction construction, we build the DEM and 3D hydraulic structures of the navigation-power junction and propose a fusion method of 3D scene based on the construction principle of digital topographic map （DEM） and applying ＂CityEngine＂ technology. Then, on the basis of the spatial database technology of ArcSDE and SQL Server, we realize the connection of the attribute data and spatial data by taking the advantage of the internal code and the user identification code as the common data item, establish the 3D scene dynamic display method to accomplish 3D dynamic visual simulation for the construction process of navigation-power junction, and design the 3D dynamic display of engineering construction and information synchronization update mechanism for the construction process to achieve dynamic visual management of the navigation-power junction construction. Finally, based on the established systemic functional framework and taking the construction management of Yilan navigation-power junction for example, we develop a 3D visual management system of the dynamic construction, expecting to provide a technical support for the visualization and delicacy management of the navigation-power junction construction.
