Abstract
A laser marking system comprises a laser, an image capture device, a marking head including electromagnetic energy deflectors and at least one lens, a beam path of the laser and a beam path of the image capture device both passing through the at least one lens, and a computer system operable to perform a method comprising capturing image tiles at each of multiple different locations with the image capture device, stitching the image tiles to produce a composite image of the marking field, identifying a location and orientation of an image of a workpiece within the composite image of the marking field, determining a location and orientation of a mark to be applied to the workpiece based on the location and orientation of the image of the workpiece within the composite image of the marking field, and applying the mark to the workpiece with the laser.
