In the ever-evolving field of geospatial mapping, the quest for accuracy and efficiency remains paramount. A recent independent study conducted by the Department of Special Geodesy at the Czech Technical University in Prague has shed light on the capabilities of modern mobile LiDAR systems, particularly in challenging environments like underground tunnels.
The Study at a Glance
Researchers undertook a comprehensive evaluation in a 120-meter-long mining tunnel, comparing the performance of traditional terrestrial laser scanners (TLS) with that of modern Simultaneous Localisation and Mapping (SLAM) based mobile scanners. The devices tested included two static scanners- Trimble Inc.X7 and FARO Technologies Focus and four SLAM-based systems from NavVis, geoSlam, Faro, and Emesent .
The primary focus was on assessing the overall accuracy of the point clouds generated by these devices, a critical factor in real-world applications.
Key Findings
- Accuracy: Emesent’s Hovermap ST-X outperformed all other devices in terms of overall point cloud accuracy.
- Data Completeness: SLAM-based scanners, including the Hovermap ST-X, provided more comprehensive point clouds with fewer gaps, owing to their mobility and reduced susceptibility to shadowing effects common in static scanning.
- Efficiency: The mobility of SLAM systems allowed for faster data collection, a significant advantage in environments where time and accessibility are constraints.
Implications for the Industry
This study underscores the advancements in mobile LiDAR technology, highlighting the potential for SLAM-based systems to not only match but exceed the performance of traditional TLS in specific scenarios. For industries reliant on precise and efficient spatial data—such as mining, construction, and infrastructure maintenance—the adoption of advanced mobile scanning solutions like the Hovermap ST-X could lead to significant improvements in operational workflows.
