摘要
介绍一种凹版印刷机计算机图像检测和位置控制系统,利用彩色边缘检测等方法对在线印刷品的图像进行实时图像处理和分析,可动态或静态显示在线印刷品图像,并得到与产品图像质量相关的参数,以此检测产品的质量;并利用各色之间的对版误差,通过伺服电机进行实时位置校正.
A imagedetecting and positioncontrol system based on computer vision for gravure printing press was introduced.Using methods like color edge detecting to process images of online printed products, the printed press image was monitored either dynamically or still,and some related parameters to evalute the quality of pressed product were obtained.The error disposition was obtained when the images of online printed products were obtained from the production line and rectified by the servomonitor
