| 摘 要： | 针对机场净空管理中存在的可视化差、精细管理不足等问题,基于三维Cesium引擎研究机场净空保护区三维信息显示与管理等关键技术。首先,依据规范要求计算障碍物限制面的三维关键点,运用Cesium构建障碍物限制面及预警阈值面的三维模型;然后,通过分层分块组织、线性四叉树索引构建,基于优先等级的数据加载优化实现海量三维数据的调度;最后,以天津机场为例建立管理系统。运行效果表明:该系统可有效提升净空安全管理的数字化水平,为机场高效运行提供了有力保障。

| Abstract: | Aiming at the problems of poor visualization and insufficient fine management in airport clearance management,the three-dimensional Cesium engine is used for the study of 3D information display and management of airport clearance protection areas.First,the three-dimensional key points of the obstacle limit surface are calculated according to the specification requirements,and Cesium is used to construct the three-dimensional model of the obstacle limit surface and the warning threshold surface.Second,hierarchical and block organization,linear quadtree index construction,priority-based data loading optimization to realize massive 3D data scheduling are used to realize the dispatch of massive 3D data.Finally,the management system is established by taking Tianjin Airport as an example.The operating results show that the system can effectively improve the digital level of clearance safety management and provide a strong guarantee for the efficient operation of the airport. |
