Camera positioning measurement
High-precision (5 million) camera for automatic positioning and automatic calibration. The resolution is 3.2 um.
With galvanometer scanning laser processing, high speed can be achieved, but there is distortion. So we need automatic correction, especially when it needs to be spliced. In the picosecond cutting, because the camera automatically measures the correction, although it is a straight line or an arc divided into blocks, no stitching is seen under the magnifying glass.
Therefore, it can be applied to various galvanometers where splicing is required, such as picosecond laser cutting, inner carving, and large-format stitching.
For 3D printing, although it does not require splicing, it requires machining accuracy, so it is also very suitable for this application.
There are several methods for correction, manual measurement, tester measurement, and direct local automatic measurement.
