摘　　要：随着数字媒体技术的发展以及个性化印刷需求的增加,在印刷过程中,对可变信息进行实时监控是满足可变信息印刷需求的必要条件。本研究采用基于机器视觉的条码信息在线检测系统,利用CCD采集条码数字图像,采用图像定位、滤波去噪、二值化、定位分割等图像处理技术进行条码处理后,用相似边距离测量法进行条码识读,实现了在线检测系统对可变信息条码的快速、精确识读与检测。With the development of digital media technology and personality printing demand, real-time controlling variable information is necessary during the printing process. In this study, the online detection system for variable information barcode based on machine vision was introduced. CCD was used to collect barcode image and the barcode was read with the similar borders distance identify method after image processing including geometric correction, filtering, thresholding, location and segmetation. The variable information barcode could be recognized fast and accurately with this system based on machine vision.
