Calibration of a Multi-Beam LIDAR by Using Linear Instrumental Error Model

Abstract:

This paper presents a method for intrinsic calibration of a multi-beam LIDAR system. Existing approach to solve the problem by taking the distance instrumental error model of the LIDAR as a constant, however, further research demonstrates the linear model is more accurate to describe the distance error of a laser measurement system. We use linear instrumental error model to calibrate the multi-beam LIDAR system. The optimization process is based on comparison the scan data with the ground truth environment. Experimental results show the efficacy of the calibration.
