The existing problem that single CCD can not meet the requirement of print image acquisition was analyzed. The method of using multiple CCD cameras in parallel to divide field of view was put forward. Series of images having overlap of two images region were acquired. The way of improved template matching and optimal fusion algorithm was selected to stitch CCD images and a complete print image was finally gotten.
