    This paper designed a step-shaped calibrator,which is easier to obtain the coordinates of the calibra? tion points and only requires the line laser to align the marked points on the calibrator once,and easier to operate than the spherical calibration method;At the same time,based on the step-shaped calibrators,this paper proposes a hand-eye calibration algorithm for line laser sensors. The algorithm uses the RANSAC(Random Sampling Consensus)algorithm to fit the calibration points,and uses the least square method to solve the hand-eye calibration ma? trix. This calibration algorithm does not need to modify the coordinates of the calibration point. The experimental re? sults show that the accuracy and stability of the step-shaped calibration method are better than those of the spherical calibration method,and the method is simple to operate and can meet most applications in the field of automatic pro? cessing.
