Abstract

Based on SLAM (Simultaneous localization and mapping) technology, the indoor 3D space is scanned, and detailed indoor 3D geographic information data is collected and constructed to give accurate 3D position information. By scanning the QR code posted in indoor space through a single data link for real-time spatial location analysis, the current location of people could be located, and the optimal path and navigation could be calculated according to the background data analysis. At the same time, the system can be quickly located and retrieved indoor personnel in reverse.
