摘要: 利用数字图像处理技术对目标对象的自动识别原理,通过模糊识别邮政编码,实现信件分拣自动化.实 验结果表明,该系统分拣效率达5件/s以上,误拣率约5%,可提高邮政信件分拣效率,加快邮件传递速度.Abstract: An automatic Chinese postal code recognition system is introduced, which is an important part of postal mail sorting systems. The images of Chinese postal codes, handwritten or printed, on envelopes are captured with a CCD sensor. Then computer image processing technique and fuzzy recognition theory are used to process and recognize the codes. Experiment shows that the sorting speed of the system is over 5 letters per second, with an error being about 5%.
