广州新白云国际机场航站楼规划验收测量

摘要

Planning topographic control traverses on base of the E-class GPS control network,the final planning sur-veying of Guangzhou new Baiyun international airport terminal with 3D laser scanning technology is completed. Analyzing result of the total station and 3D laser scanner,it shows that the 3D laser scanning technology has a good application pros-pect in completion surveying of building with complex structures or large scales. In addition,this paper achieves dynamic update data through the transformation between vector data and GIS data.%基于E级GPS控制网布设图根导线进行细部观测，结合三维激光扫描技术完成广州新白云国际机场航站楼规划验收测量，并将成果进行数据整理，实现地形图动态更新。通过全站仪观测数据与三维扫描结果的对比分析，表明三维激光扫描技术在结构复杂、超大规模建筑物测量中具有较好的应用前景。
