Abstract

In response to the difficulties of processing massive laser point cloud off-site real-time scanning and on-site absolute coordinate system registration, a low-cost ground-based lidar measurement system is developed by combining Beidou/GNSS positioning system and 5G communication technology. The measurement system consists of LIDAR, a high-precision motor, BeiDou/GNSS receiver module and 5G module integration. Technology for real-time transmission. The terminal carries out multi-frame point cloud time registration by linear interpolation algorithm through self-developed data pre-processing software, coarse registration of multi-station laser point cloud according to BeiDou/GNSS coordinates, and then fine registration using Rodriguez matrix to complete the overall registration and visualization on the self-developed real-time point cloud management and visualization system. The experiments show that the measurement system can realize off-site scanning and transmission and provide data infrastructure for real-time application fields such as digital twins, monitoring of physical and cultural heritage, and analysis of construction and operation and maintenance of mega-shaped buildings.
