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.

Laser marking through the lens of an image scanning system

A laser marking system includes a laser, an image capture device, a marking head including electromagnetic energy deflectors and a lens, beam paths of the laser of the image capture device both passing through the lens, and a computer system. The computer system is programmed to perform a method including generating an image calibration model at each of multiple areas across a marking field of the laser marking system, adjusting the electromagnetic energy deflectors to direct the beam path of the image capture device to multiple different locations within the marking field of the laser marking system, and capturing image tiles at each of the multiple different locations with the image capture device, wherein at each of the multiple different locations, if a location corresponds to an area at which an image calibration model was generated, correcting the image tile according to the image calibration model generated at the location.
