摘要
在线路三维建模技术和方法中,路基三维建模方法及与地形三维模型的交接、融合是技术关键和难点。在分析当前路基三维建模方法的基础上,对地理信息系统(GIS)环境下路基模型与地形模型的叠加进行了研究,提出利用GIS控件实现路基的三维建模和可视化的方法,并对实现的关键技术进行了论述。
From the view of track 3D modeling technology and method, the key point and difficulty of the technology is the connection and integration of the roadbed 3D model with terrain 3D model. Under the basis of analyzing the current roadbed 3D modeling method, the paper studies the overlay of roadbed model and terrain model under the condition of GIS, puts forward the method of realizing roadbed 3D modeling and visualization by using the GIS control, and expounds the methods of realizing the key technologies.
