本文所要讨论的是数字数字摄影测量在三维地形和公路设计方面的应用,就是如何通过航空摄影资料和摄影测量理论进行三维地形道路设计、管理分析提供科学有效的依据。既利用摄影测量的基本成果地形平面图的数据和数字高程模型(DEM)实现京化高速公路路段三维地形的显示和实时浏览,对于京化公路的选线、绕避不良地质灾害的发生和开凿隧道的位置选择等将会有一定的参考价值。
This article discusses the application of digital photogrammetry in 3D terrain and highway design, which is how to provide scientific and effective basis for 3D terrain road design and management analysis through aerial photographic data and photogrammetry theory. Both the data and digital elevation model (DEM) of the basic achievements terrain plan of photogrammetry are used to realize the display and real-time browsing of the 3D terrain of the section of Beijing-Huaihua Expressway. For the route selection of Beijing-Huaihua Highway, the occurrence of adverse geological disasters and tunneling The location of choice will have some reference value.
