Problems solved by technology
In related technologies, a laser is used to emit laser light or pointing light, and the laser line is scanned on the workpiece through a three-dimensional galvanometer, so that the three-dimensional shape of the workpiece is generated online by using the principle of three-dimensional structured light, and the laser in-situ three-dimensional processing is performed after the in-situ processing path is generated. However, this implementation method has strict requirements on the installation accuracy of the galvanometer, but its installation process relies on manual implementation, resulting in inaccurate calibration results
