In recent years, with the continuous improvement required print quality, in order to control the generation of bad printing in minimum
Limit forbids defective products to circulate outward, it is desirable that printing scene must be set up stringent production system and management system.Some prints
It is very high to brush enterprise's especially requirement of the tobacco company to quality, once there are quality problems, will result in a large amount of return of goods.In order to drop
Low-risk, most of printing houses all take the method that artificial full inspection is implemented to printed matter.But artificial full inspection is there are its limitation, and
It does not say that people can have visual fatigue, only to detect the various problems that may occur in printing within the extremely short time, this
It has been the work of a great difficulty.Therefore want real guaranteed quality, accomplish zero-fault, checked automatically using print quality be must
Indispensable.
At the same time, the detection means of printed matter also has occurred change and considers production efficiency or economy.By video camera
With the printing quality detecting device of signal processing circuit composition, start to be widely adopted instead of vision-based detection, such as after processing
Printed matter detected with checking machine, it may be found that bad part removing be allowed to become excellent product etc..
With network, the fast development of video communication technology and the extensive use of video monitoring system, the matter of monitoring image
Amount evaluation just becomes new research hotspot.Since video monitoring system is usually deployed to ensure effective monitoring and control of illegal activities, range is larger, and product quality test point is more, because
This front end image capture device long continuous operation and by various exogenous influences, monitoring video is easily by various aspects interference and under quality
Drop, and it is difficult cumbersome to operate.
According to the analysis to print quality influence factor, it is known that its defect is generally shape defect.It is primarily upon shape
Shape feature, such as stripe shape defect.In most available picture quality detections, there are some to be suitable for evaluation image quality
