Abstract

We propose a new calibration method for a laser galvanometric scanning (LGS) system by adapting the camera model to model the LGS system. The similarity between the camera system and the LGS system has been investigated and exploited. The distortion parameters are acquired by solving a nonlinear least squares problem of 12 coefficients using the Levenberg–Marquardt algorithm. The efficiency of the calibration is improved. Experiments are conducted to verify the proposed model.
