Abstract: A laser machining method includes obtaining attribute information indicating a distribution of an attribute of a workpiece in a machined area of the workpiece, dividing a shape of a radiation locus into divided areas, and adjusting, based on the attribute information and in each of the divided areas, at least one of a locus velocity of a laser from a head configured to variably make the radiation locus on the workpiece using the laser, and an output of the laser from the head. The head is moved by a robot configured to move the head.

Abstract: A laser machining method includes obtaining a movement direction in which a head that variably makes a shape of a radiation locus using a laser is being moved by a robot that causes the head to move along a machining line, and adjusting the radiation locus made by the head to keep a constant relative angle between the movement direction obtained by the obtaining and a representative angle of the shape of the radiation locus.

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.
