Precision analysis of wearable three dimension laser scanning system in typical underground space
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.
