In summary, in the actual calibration process, the inclination direction of the optical mirror 32 can be adjusted by the first adjusting plate 42 to adjust the emission directions of the visible light and the laser; the second adjusting plate 45 can also translate the position on the optical mirror 32 in a certain direction to adjust the relative positions of the visible light and the laser; the two modes are combined for use, so that the light-emitting light path of visible light can be overlapped with the light-emitting light path of the laser relatively quickly; and the emergent direction and position of the laser can be rapidly determined.
