倾斜摄影测量辅助城市地铁前期规划研究
|
摘要
为了解决地铁线路建设前期涉及的地铁保护区设置、征地拆迁、管线迁改及交通疏解等规划管理问题,采用了以倾斜摄影测量技术为辅助的三维数字化规划管理方法。首先利用无人机搭载倾斜摄影相机获取沿地铁规划路线的倾斜影像,并通过空三解算、影像密集匹配、不规则三角网构建及纹理映射等进行三维实景重建。然后结合数字正射影像、数字高程模型及建筑信息模型等数据,构建多图层的地铁沿线三维地理信息系统。在此基础上,运用空间信息量算、缓冲区分析、叠加分析以及网络分析等空间分析技术完成上述前期规划管理工作。以某市地铁线路的前期规划管理为例,验证了该方法的有效性和科学性,克服了传统方法数据采集效率低、分析结果不直观以及无法与地理坐标相对应的不足,实现了地铁建设前期的数字化规划管理。
In order to solve the planning and management problems of subway protection zone setting,land acquisition and demolition, pipeline relocation and traffic organization in the early stage of subway construction,a three-dimensional digital planning management method based on tilt photogrammetry is adopted. First,tilted images along the subway route are obtained using UAV with tilt cameras. And the threedimensional real scene reconstruction is carried out by aerial triangulation solution,image intensive matching,TIN construction and texture mapping. Then,combined with DOM,DEM and BIM,a multi-layer threedimensional geographic information system along the subway is constructed. On this basis,spatial analysis techniques such as spatial information calculation,buffer analysis,overlay analysis and network analysis are used to complete the preliminary planning management. Taking the pre-planning management of a subway line in a city as an example,the effectiveness and scientificity of the method are verified,which overcomes the shortcomings of traditional methods such as low data collection efficiency,unintuitive analysis results and the inability to correspond to geographic coordinates and realizes the digital planning and management in the early stage of subway construction.
