摘要：
A method is disclosed for calibrating a camera used in a scanner for scanning images onto a printed circuit board. The calibration method determines a transformation between the camera and the scanner by writing a pattern on a photosensitized substrate using the scanner, where the pattern is visible without development, and using the camera to image the pattern, from which a transformation between the imager and scanner coordinate systems is determined.
