Laser calibration method and device for spray gun

The invention discloses a laser calibration method and device for a spray gun. The method comprises the steps: acquiring the projection position of a laser beam of a laser emitter on a target; judgingwhether the projection position is in a target area or not; and if the projection position is in the target area, enabling the spray gun to executesspraying operation. Before spraying operation of the spray gun is started, whether the spray gun executes the spraying operation or not is controlled by judging whether the projection position of the laser beam of the laser emitter on the target is inthe target area or not, the initial position of the spraying operation of the spray gun is calibrated, and the situation that the spraying effect is poor and the spraying raw materials are wasted dueto the fact that the initial position of the spraying operation of the spray gun is wrong is avoided; and the yield of the to-be-sprayed component is increased. 本发明公开了一种用于喷枪的激光校准方法及装置，其中该方法包括获取激光发射器的激光束在目标靶上的投影位置；判断所述投影位置是否在目标
