  • Patent number: 10873739
    Abstract: A calibrating method includes controlling a laser radiator to radiate calibration laser light to an object such that a pattern is projected in a laser coordinate system with respect to the laser radiator; controlling a camera to obtain a first image of first light points of the calibration laser light projected on a surface of the object when the object is in a first position; and controlling the camera to obtain a second image of second light points of the calibration laser light projected on the surface of the object when the object is in the second position. A positional relationship between the laser coordinate system and the camera coordinate system is calculated based on the three-dimensional positions of the first light points and the three-dimensional positions of the second light points.
