PROBLEM TO BE SOLVED: To attain highly accurate machining and confirming, for example, in quality control through proper beam control and image recording, on the basis of precise positional control and recognition of irradiation state through image processing by placing a camera coaxially with a beam operation axis.SOLUTION: Plane mirrors are mounted on an arc relative to an arbitrary irradiation range, with beams distributed from the center of the arc, and horizontal divided emission is performed on a workpiece surface at a focal distance less than an irradiation width to the workpiece. The positions of the respective plane mirrors are those of the equal focal distance and at an angle reflecting the beams from the center vertically to the workpiece. The control is performed such that the imaging axis of the camera is placed coaxially with the beams. The beams are emitted by obtaining a position and class information of the target from the image, and manipulation of the position and output of the beams are performed by determination from the image of the situation. |
