Patent ID: 8169478

Claim:
A method for calibrating a mark quality verifier assembly wherein the assembly includes a camera including a camera field of view (FOV) and a processor for running software programs that are stored in a memory that is accessible to the processor, the method comprising the steps of: providing a calibration program in the memory that is accessible by the processor; providing a calibration code on a surface of a calibration tool wherein the calibration code includes calibration information target parameters; positioning the calibration tool adjacent the camera so that the calibration code is within the FOV; obtaining at least one image of the calibration code via the camera; decoding the calibration code to generate a decoded code; examining the decoded code to identify the calibration target parameters; using information in the decoded code to determine that a verifier calibration process should be performed; commencing the calibration program when the calibration code indicates that a calibration process should be performed; and using the calibration target parameters to set at least a subset of verifier parameters for use during subsequent calibration program steps.
