The present disclosure discloses a method for using a laser level to track a detector and a laser tracking system. The method is applied to the laser level, which needs to use a fan-sweep mode or a dot-sweep mode. The method includes emitting a laser beam by the laser level to perform circular scanning, during the circular scanning, when the detector detects the laser beam, sending a detection signal to the laser level by the detector, when the laser level receives the detection signal, using the laser beam emitted by the laser level to perform circular scanning in an opposite direction, and when a frequency of the detection signal received by the laser level is greater than a first threshold, determining that the laser level tracks the detector.

Method and laser tracking system for using laser level to track detector

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.

Method and system for calibrating laser level

The present invention relates to a method of positioning a target object in a target space by means of a ranging apparatus, the method comprises: acquiring a first size parameter of the target space on a first dimension; acquiring a second size parameter of the target object on the first dimension; and determining a first layout indication according to the first size parameter, the second size parameter and a first predetermined rule, the first layout indication containing information regarding a first target position of the target object on the first dimension of the target space. By means of the method in accordance with the invention, a desired positioning of the target object in the target space by means of a ranging apparatus may be implemented, such as being placed at the center or being placed at a one-third aliquot point, thus implementing the object placement and layout in the object space.
