Aiming at the attributes of the high speed of cigarette package moving and strong noise in the field environment, the thesis carries out a dynamic imaging mode of random outer trigger and obtains the cigarette package images with high quality and high precision. The median filtering, image segmentation and other techniques of image pre-processing are applied to the character images, and the techniques of pattern recognition are employed to recognize the characters. The thesis optimizes and improves the recognition algorithm to satisfy the requirements of high speed real-time processing system. The whole system can online inspect and take statistics the print quality of the forgery-proof symbols on the outer packing of cigarette, achieving good results.
