摘　　要：针对传统的城市地下空间测量方法存在的困难和问题,试验了一种基于3DSLAM(Simultaneous Localization And Mapping—实时定位与制图)移动扫描技术的地下空间测量新方法。采用i MS3D三维移动测量扫描仪对南京市新街口地区的地下空间进行了扫描测量,分别对地下停车场、地下通道、地下商场等不同类型的地下空间进行了快速高效的三维激光点云数据采集和实景影像采集,通过后处理软件,实现了对不同地下空间结构的测量,测量结果满足相关规范要求,同时还实现了对地下空间主要建(构)筑物的三维建模及实景影像管理。试验结果表明:该技术不仅可以快速有效地对地下空间进行快速有效的数据采集和测量,还可以同步构建三维模型及实景影像,为城市地下空间测量提供了一种新的技术手段。Aiming at the difficulties and problems of city underground space of the traditional measurement methods,a test based on 3D SLAM(Simultaneous Localization And Mapping) a new method of underground space measuring mobile scanning technology.Using i MS3 D three-dimensional scannerin Xinjiekou District of Nanjing city underground space of scanning,respectively on different types of underground space such as the underground parking lot,underground tunnels,underground shopping malls for the rapid and efficient three dimensional laser point cloud data acquisition and digital measurable image acquisition,through postprocessing software and realizes the measurement of different underground space structure,the results meet the requirements of the relevant regulations,but also the realization of the underground space in the main building(structure) 3D modeling and digitalmeasurable image management structures. The test results show that: Based on the technology not only can be fast and efficient data collection and measurement quickly and effectively to the underground space,can also be synchronized to build 3D model and digitalmeasurable image,provides a new technical means for city underground space measurement.
