Abstract
A method of calibrating a light-curtain system of an autonomous mobile robot (AMR) is provided. The method includes providing a scanner set at a height above a ground surface and outputting a laser scanning beam downwardly reflect from at least one mirror; providing and/or determining initial mirror angles, mirror positions, and lidar height; calculating a lidar height from scanner data; determining a gradient vector as a byproduct of the lidar height calculating; adjusting mirror angles, mirror positions, and lidar height in a direction opposite of the gradient vector; assessing of the adjusted mirror angles, mirror positions, and lidar height are equal to or less than thresholds; and if so, storing the mirror angles, mirror positions, and lidar height and/or values representing a ground plane.
