mdInfinity offers high value software to improve geospatial data workflows and the quality of deliverables. In this web paper, LIBAC: LiDAR-IMU Boresight Automatic Calibration, mdInfinity reviews and explains the methodology of the Microdrones LIBAC tool, and how the misalignment is computed automatically and boresight angles can be applied to georeference the data set without any boresight bias.
Without careful calibration of the boresight angles from LiDAR systems, data collected could impact your results in different ways that could prevent the point cloud matching. Hence the alignment between IMU and camera or LiDAR sensors needs to be determined frequently, including after payload integration, project calibration, or scheduled calibration. LIBAC (LiDAR -IMU Boresight Automatic Calibration) is an automatic tool for boresight calibration developed by mdInfinity from recent state of the art research.
With the Microdrones LIBAC tool, the misalignment is computed automatically and boresight angles can be applied to georeference the data set without any boresight bias. LIBAC is not dedicated to a specific LIDAR. It can be used for the calibration of any LiDAR system and it adapts to its uncertainty level. LIBAC has already been used to calibrate SICK, Velodyne VLP16, Riegl miniVUX-1UAV, Riegl miniVUX-DL, Riegl VUX-LR LiDAR and various INS.
In this web paper mdInfinity will present the findings and results for:
- Data selection
- Extraction of planar surface elements
- Boresight sensitivity criterion
- Estimation of boresight angles
- LIBAC practical use
- LIBAC Results
Learn how LIBAC, from mdInfinity, is automatic, rigorous, and provides accurate results, powered by the most advanced data selection tool. Even a non-expert is able to use LIBAC and enable any user to easily and automatically calibrate any type of mobile mapping systems for any brand of LiDAR.
