In this paper, a target-free automatic self-calibration approach for multibeam laser scanners is proposed. The proposed approach uses the isomorphism constraint among the laser scanner data to optimize the calibration parameters, uses the ambiguity judgment algorithm to solve the mismatch problem, and finally achieves the purpose of automatic calibration. The experimental results show that the accuracy of our algorithm is higher than that of the target-based calibration approach. The calibration process is automatic and fast.
