Abstract
A method for calibrating a laser level. includes arranging the laser level and a detector on a same horizontal plane to cause the laser level to be at a detected position, setting the laser level to be in a dot-sweep mode or a fan-sweep mode, when the detector detects the first laser beam for calibration emitted by the laser level, generating first position information by the detector, when the laser level rotates to a first rotation angle, rotating a laser projection direction of the laser level relative to the laser level along the opposite direction by a first rotation angle to cause the detector to detect the second laser beam for calibration emitted by the laser level to generate second position information, and determining whether the laser level needs to be calibrated based on the first position information and the second position information.
