摘　　要：针对高速印刷图像处理中的高实时性要求,分析了高速印品图像的图像特征,提出了一种利用灰度形态学提取轮廓进行快速图像配准的方法。对配准后的图像,采用改进的图像差分算法进行图像比较和形态学滤波,能够快速准确地将印刷缺陷提取出来。实际应用表明,该算法能满足最高300 m/m in彩色印品质量检测的需要。To meet the needs of high real-time of the high-speed image processing, a fast image registration algorithm was proposed through the contours extracted by mathematic morphology of gray image based on the analysis of the printing image characteristics. With the help of such an improved algorithm, printing defects could be detected rapidly and accurately by the image subtract and morphology filter. It is shown by practice that the algorithm can meet the requirement of high printing speed up to 300 m/min.
