摘要:
铁路与公路工程为带状线性工程,线路长度通常达数百甚至上千公里,涉及区域多、范围广。基础地理信息数据通常采用1∶10 000及1∶2 000地形图,基于此进行二维选线设计。随着航空摄影技术的出现,可对地形进行全方位的拍摄,获得实景三维地图,在此基础上开展铁路及公路选线设计工作,比二维地形图具有更好的直观性、信息量和精确性。本文将实景三维地形和三维建模技术相结合,实现了设计成果的真实展现,为未来工程建设规划设计的实体再现提供技术支撑。
Abstract:
Railway and highway projects are strip-shaped linear projects, and the length of the line usually reaches hundreds or even thousands of kilometers, involving many areas and a wide range. The basic geographic information data is usually based on 1∶10 000 and 1∶2 000 topographic maps, on which the two-dimensional route selection design is carried out. With the emergence of aerial photography technology, the topography can be photographed in an all-around way to obtain live 3D maps, on which basis the design of railway and highway route selection can be carried out, and it has better intuition, information, and accuracy than 2D topographic maps. In this paper, the combination of live 3D topography and 3D modeling technology realizes the real presentation of design results and provides technical support for the physical representation of future engineering construction planning and design.
