Design and implementation of a new kind of printing image detection system

                                  NIU Yi-fan

      (Jining College of Technician, Jining 272000, China)

      Abstract: In order to meet the needs of high-speed and high-precision registration and detection of large-area printing image in actual printing production, a new kind of printing image detection system is designed. In this system, many CCDs are used to acquire image information simultaneously锛宎nd the acquisition and transmission of image data are controlled by CPLD and PCI bus, and a new image registration algorithm is adopted in image preprocessing. The related programs and algorithms of this system are implemented by DDK and VC programming language. The experimental results show that this system meets real-time need basically, its image registration is faster, more accurate and its adaptability is stronger, so it has a certain practical value.

      Key words: printing image detection; image acquisition; image preprocessing; registration and positioning; matching and detection
