机场净空区与障碍物精细化三维建模与表达

Refined Three-Dimensional Modeling and Expression of Airfield Clearance Zone and Obstacles

针对机场净空区与障碍物三维可视化中出现的问题,本文依据民用机场飞行区的相关技术要求与标准,对机场净空区进行精确计算,并基于三维建模软件Sketch Up对机场净空区与机场周边障碍物进行精细化建模研究。针对障碍物模型构建分类体系,建立障碍物模型库,使用开源三维框架Cesium进行综合展示。研究结果表明,通过Sketch Up进行精准三维建模,进行净空区与障碍物三维场景的展示,为后期进行超高分析、数据管理等提供技术支持。

In view of the problems in the three-dimensional visualizatioh of sirfield clearance zone and obstacles,this paper accurately calculates the Airfield Clearance Zone based on the relevant technical requirements and standards of the civil airport flight zone.And based on THE 3D modeling software Sketch Up,refined modeling research was conducted on the airport clearance area and obstacles around the airport.The classification system is built for obstade models,the obstacle model library is established,and the open source 3D framework Cesium is used for comprehensive display.The research results show that the accurate three-dimensional modeling is performed by Sketch Up,and the three-dimensional scenes of the airfield clearance zone and the obstacle are displayed,which provides technical support for the ultra-high analysis and data management in the later stage.
