Abstract

This study investigates the geometric accuracy and coloring of LiDAR and camera sensors within the confined and complex environments of narrow underground structures, such as Erdstall facilities. Accurate spatial data acquisition in these settings is crucial for mobile navigation, structural monitoring, and geological surveying applications. We collected and analyzed data from LiDAR and camera systems through controlled experiments, comparing their outputs against high-precision ground truth measurements. Key performance metrics such as geometry, spatial resolution, 3D wall and color structure, error rates, and data completeness were assessed.
