Laser printing quality checking system and method based on CCD image-forming

Abstract

The invention provides a detection system of laser printing quality and a method thereof, which are based on CCD imaging and which are used for detecting the printing quality of the detected product in the target detection position. The system comprises an optical imaging system and an image processing system. The optical imaging system comprises a linear array CCD camera, an optical lighting component and an installation regulating component; the optical lighting component is superposed on the normal line of the target detection position; the included angle of the linear array CCD camera and the target detection position is more than 0 degree and less than 90 degrees; the installation regulating component is respectively connected with the linear array CCD camera and the optical lighting component. The detection system adopts the CCD imaging method to collect high-quality images of laser printed matters, which are processed by the image processing system, and realizes the automatic detection of the quality of the printed matter in the special technologies of gold tooling, silver tooling, laser, and so on in the current printing industry.

Description

technical field [0001] The invention relates to an automatic detection of the production quality of a special printing process, in particular to a laser printing quality detection system and method based on CCD imaging. Background technique [0002] With the continuous growth of the customer market in the printing industry and the increase in product value, people are paying more and more attention to the printing quality of products with special printing processes such as laser. Because this special printing product has the characteristics of high light reflection and different imaging at different angles, it can only rely on manual inspection at present. Due to individual differences and easy fatigue, manual inspection cannot guarantee the consistency of product features and product quality. Stability, the use of machine vision image technology to automatically detect printed matter has become an inevitable development of the printing industry. [0003] For the detection ...
