无棱镜测量技术在城市规划测图中的应用

Application of prismless surveying technology in uban planning mapping

文中以城市规划中的地图测绘为例,探讨了无棱镜测量技术在大比例尺地图测绘中的应用。实验分析表明,无棱镜测量技术与有棱镜测量精度相当,满足城市规划制图精度要求。且以唐山市某小区作为项目区进行了实施,结果表明,无棱镜测量技术在城市密集建筑区具有较强的适用性,特别是在小范围城市规划用图测绘、三维建模数据获取等方面具有速度快、精度高、成本低等优点,是解决城市规划建设与设计施工快速用图的重要测量方法。

Taking the mapping in urban planning as an example,in this paper,the application of the prismless surveying technology was discussed in the large-scale mapping.Experimental analysis showed that the accuracy of the prismless surveying was equivalent to that of the prism surveying,which could meet the accuracy requirements of the urban planning mapping.And then,it was implemented by taking a community in Tangshan as the project area,the results showed that the prismless surveying technology had the strong applicability in the urban dense building areas,in particular,it had the advantages of fast speed,high precision and low cost in the aspects of the small scale urban planning and mapping,3D modeling data acquisition,etc.,which was an important surveying method to solve the rapid use of drawings in urban planning and construction and design and construction.
