Abstract
A device for calibrating a laser level includes a base platform, a target, and an image recognition device. The base platform is configured to support the laser level that is to be mounted on the base platform at a first position. The target is arranged at a second position of the base platform and configured to receive a laser. The image recognition device is configured to obtain images of lasers projected on the target before and after the laser level rotates a first angle, determine, based on an image recognition result of the images, positions of the lasers emitted by the laser level to determine a deviation distance, and determine whether the laser level needs to be calibrated based on the deviation distance. The deviation distance is determined by position data of the first position and the second position, and the first angle.
