Abstract

Abstract: Underground space utilization has attracted more and more people’s attention. Underground space measurement is affected by many factors, such as the lack of GPS signals in the underground space, more obstructions, and low efficiency of traditional methods. To solve this problem, this paper proposes a data acquisition scheme combining on-board laser scanning system and ground 3D laser scanning. This scheme can effectively utilize the advantages of ground 3D laser scanning and vehicle mobile laser scanning, and adopt a multi-source point cloud data. Fusion technology to efficiently acquire complete point cloud data in underground space. Finally, through the underground garage data collection experiment, the effectiveness and reliability of the scheme are verified, and provide technical support for the future extensive development of underground space mapping.

Key words: ground laser scanning, mobile laser scanning, indoor three-dimensional, indoor mapping, data fusion
