【摘要】 传统印刷图像质量检测方法采用测控条检测,其结果的可重复性和稳定性都不能得到保证。本文应用机器视觉技术,结合印刷质量检测原理与数字图像处理技术,建立了全画面印刷图像质量检测系统,提出了系统的理论设计与模型。系统使用彩色面阵CCD,采集印刷品图像,视频信号经图像采集卡,通过计算机PCI总线传输到内存中,在系统的软件中对图像进行处理和分析。实验主要完成了数字图像的数据转换和印刷品的墨量显示。更多还原

【Abstract】 The traditional printing checking method always uses printing control strips,but the results are not very well in repeatability and stability. In this paper,the checking methods for printing quality basing on image are taken as research objects. On the base of the traditional checking methods of printing quality,combining the method and theory of digital image processing with printing theory in the new domain of image quality checking,it constitute the the checking of printing quality system basing on image processing,and expound the theory design and the model of this system.. This is an application of machine vision. It uses the high resolution industrial CCD(Charge Coupled Device) colorful camera. It can display the real-time photographs on the monitor,and input the video signal to the image gathering card,then the image data transmits through the computer PCI bus to the memory. At the same time,the system carries on processing and data analysis. This method is proved by experiments. The experiments is mainly about the data conversion of image and ink limit show of printing.更多还原
