摘要
本文阐述了青岛市地下空间普查背景,针对传统的地下空间测量方法存在的困难和问题,试验了基于移动背包三维扫描技术的地下空间测量新方法,介绍了移动背包扫描系统的测量原理、工作模式以及精度分析,采用徕卡移动背包扫描系统对青岛市中央商务区地下空间进行了扫描测量,结合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地下空间结构的测量。试验结果表明:移动背包三维系统可以快速有效地对地下空间进行数据采集和测量,还可以同步获取空间实景影像,为城市地下空间测量提供了一种新的技术手段。
This paper expounds the background of underground space survey in Qingdao City, and in view of the diffculties and problems existing in traditional underground space survey methods, a new underground space survey method based on mobile knapsack three-dimensional scanning technology is tested. The measuring principle, working mode and precision analysis of mobile knapsack scanning system are introduced, and Leica mobile knapsack is adopted. Packet scanning system scans and surveys the underground space of Central Business District in Qingdao, combines effcient 3D laser-point cloud-data acquisition and real-time image acquisition, and realizes the measurement of underground space structure by post-processing software. The experimental results show that the mobile knapsack 3D system can quickly and effectively carry out underground space measurement. Effective data acquisition and measurement can also synchronize the acquisition of real-time images of space, which provides a new technical means for urban underground space measurement.
