摘要
针对地下空间三维信息获取困难的问题,研发了地下空间移动激光测量系统。该系统分为动态测量部分和静态纠正部分,动态测量部分由线阵激光扫描仪、高精度IMU和里程计等传感器高度集成,安装在轻便的移动平台上,在移动过程中快速获取地下空间三维点云信息;静态纠正部分由一系列三维空间合作标靶组成,根据一定原则分布在地下空间中,其作用相当于控制点组合,对移动测量系统获取数据进行位置和姿态纠正。论文在阐述地下移动激光测量系统工作原理的基础上,重点阐述了系统集成中的几个关键技术问题,包括硬件系统集成、三维合作标靶研发、位置姿态纠正等,最后以实例应用说明了该系统的高效性和精确性。
In order to solve the problem that 3-D information of underground space was collected difficulty, underground space trans-portable laser surveying system was developed.The system included dynamic surveying part and static correction part, dynamic survey-ing part was integrated highly with many sensors, which included linear laser scanner, high precision IMU and odometer, it was in-stalled on portable movement platform, and 3-D point cloud information of underground space were collected quickly during movement process, static correction part was composed by series 3-D space collaboration targets, which distributed in underground space accord-ing some specificity principle, its action was controlling points combination , and position and attitude of data that collected by move-ment measurement system were corrected.Some key technological problems of system integrated were illustrated specially, which in-clude hardware system integrate, 3-D collaboration targets development, position attitude correction and so on, high efficiency and precision of system was illustrated by its application.
