摘要
城市轨道交通线路三维规划设计需要更加真实、准确和完整的城市三维实景环境,而现有的建模方法在精度、速度和真实度上已无法满足这种要求。采用倾斜摄影技术,实现了城市三维实景环境快速建立和模型单体化的建模方法,建立具有全要素并带有高精度地理信息的城市三维实景环境,满足线路三维规划设计要求。基于3DGIS(三维地理信息系统)和二次开发技术,实现了三维场景融合和三维实景环境下的线路规划设计及方案的三维漫游展示,为城市轨道交通三维规划设计提供了新的解决方案。
The 3 D planning and design of urban rail transit requires more real,accurate and complete 3 D real scene urban environment.However,the existing modeling methods cannot meet these requirements in terms of accuracy,speed and realism.In this paper,the tilt photography technique is adopted to realize the rapid modeling and the model singularity of 3 D urban real-scene environment,and establish the 3 D urban real-scene environment with full element and high-precision geographic information,which could meet the requirements of route planning and design.Based on 3 DGIS(geographic information system)and secondary development technology,the 3 D scene fusion,the route planning in 3 D real-scene environment and the 3 D roaming display of schemes are realized,providing a new solution for 3 D planning and design of urban rail transit.
