摘要:本文以崇文至紫荆500kV线路工程为例，探讨超高压输电线路工程三维全景可视化技术路径，包括：采用卫星影像数据和高精度数字高程数据合成输电线路工程地形地貌模型；运用无人机倾斜摄影技术进行敏感区域重要建筑地物实景建模；基于BIM技术对铁塔、输电线等进行建模；最后采用SuperMap 3D Designer三维地理设计引擎进行倾斜摄影、激光点云图以及BIM模型等数据融合处理，实现省市远景视角、镇村中景视角及铁塔近景视角的三维全景展示。研究结果表明基于GIS、倾斜摄影、BIM建模以及三维引擎技术融合的三维建模技术能够全方位展示超高压输电线路地形地貌，真实反映交叉和跨越情况，为超高压输电线路工程的精细化管理提供了支撑。
Abstract: Based on the 500kV Chongwen-Zijing transmission line project, this paper discusses the technical approaches of 3D panoramic visualization of Extrahigh-Voltage (EHV) transmission line project. These approaches include the following: Firstly, the geomorphologic model of transmission line project is generated by using satellite image data and high-precision digital elevation data (DEM). Secondly, the slope photography technology is used to model the real scene of important buildings and ground objects in sensitive areas. Thirdly, BIM Technology is used to model transmission tower and transmission line. Finally, the SuperMap 3D Designer engine is used to fuse the geomorphologic model, the slop photography model and BIM model. In this way, three-dimensional panoramic display from different angles can be realized, such as provincial and municipal perspective, village and town perspective, tower perspective, etc. The research results show that the three-dimensional modeling technology based on the integration of GIS, slope photography, BIM model and three-dimensional engine technology can comprehensively display the landform of EHV transmission line project, truly reflect the crossing situation, and provide support for the fine management of EHV transmission line project.
