Use high-precision (5 million) camera for automatic positioning and automatic calibration. The resolution is 3.2 um.
Using galvanometer scanning laser processing can achieve high speed, but there is distortion. So we need automatic correction, especially when stitching is needed. In picosecond cutting, due to the automatic measurement and correction of the camera, although it is a straight line or arc segmented and divided into blocks, there is no trace of splicing under the magnifying glass.
Therefore, it can be applied to various galvanometers that need to be spliced, such as picosecond laser cutting, internal carving, and large-format splicing marking.
For 3D printing, although splicing is not required, processing accuracy is required, so it is also very such an application.
