摘　　要：针对三维激光扫描系统在地下空间测量不同场景的测量精度及其适宜性分析不够系统和全面的问题,提出一种典型地下空间穿戴式三维激光扫描系统:使用穿戴式三维激光扫描系统采集3种典型地下空间的三维点云数据,并制作典型地下空间平面图;然后通过实测数据验证穿戴式三维激光扫描系统在典型地下空间的测量精度,并分析其适用性。结果表明,穿戴式三维激光扫描系统获取的地下空间点云数据平面及高程精度均优于3 cm,可满足3种典型地下空间场景测量精度要求,能够提高生产效率,获得较好的应用效果。Aiming at the problem of insufficient systematic and comprehensive analysis on the measurement accuracy and suitability of three dimensional(3D)laser scanning systems in different scenarios of underground space measurement,the paper proposed a wearable three dimension laser scanning system in typical underground space:a wearable 3D laser scanning system was used to collect 3D point cloud data of three typical underground spaces,and a typical underground space plan was produced;then,the measurement accuracy of the wearable 3D laser scanning system in typical underground spaces was verified through actual measurement data,and its applicability was analyzed.Results showed that the accuracy of the underground space point cloud data plane and elevation obtained by the wearable 3D laser scanning system would be better than 3 cm,fully meeting the accuracy requirements for measuring three typical underground space scenes,indicating that the proposd method could improve production efficiency and achieve good application results.
