Automatic Multiple LiDAR Calibration Based on the Plane Features of Structured Environments

Abstract: The multiple light detection and ranging (LiDAR) system has been attached to numerous autonomous vehicles to reduce blind spot risks and increase measurement resolution. It is also important to accurately aligning multi-LiDAR data because misaligned sensor data can affect the localization and perception algorithms of LiDAR sensors. However, precise extrinsic parameter estimation is a challenging research area because the feature points in LiDAR data cannot be precisely aligned owing to the LiDAR resolution. In… Show more

“…Physical models model the errors of LiDAR based on physical parameters, such as ranging, angle measurement, and quadrature errors, while empirical models are based on empirical parameters [ 14 , 15 , 16 , 17 ]. To reduce the correlation among model parameters, these parameters can be treated as observations with prior information [ 18 , 19 , 20 ], or the strongly correlated parameters are grouped and calibrated step by step [ 21 , 22 ].…”
