Machine vision has become in our country started as early as a typical case for using batch and success.

First of all, the tobacco industry is relatively high national profit rate for control of production industry, so there are sufficient funds to support the application of new technologies to control the quality of products, improve the image of. The second is now the cigarette production line production speed faster and faster, from the early 300 packs per hour, up to now has reached 800 per minute, depending on the online detection of production personnel and manual with almost no possibility of defect cigarette packets.

In 2002 Chinese cigarette manufacturing also began using the machine vision technology, compared with other industries, China cigarette manufacturing machine vision applications become a common practice. The application and development of 8 years, the cigarette production line appearance and the appearance of small packet detection has become the necessary equipment, the installation rate of more than 90%, and got very high appraisal and recognition, so the tobacco industry has gradually put the machine vision detection technology and product extension to silk, smoke, tobacco processing, tobacco smoke covers: foreign body, only to drop defect, box number, material quality defects detection, anomaly detection of packaging equipment. The cigarette box production as an example, the process of cigarette, the box in the packet process because of quality defects or transparent paper packing machine itself will cause the appearance quality defects, a box of varying degrees of mainly has: a box of anti package, transparent paper, cellophane, broken lack of transparent paper serious wrinkles, transparent paper fouling, sealing, foreign body, deletion, inclined pull pull, pull the wrong tooth breakage; in addition to a box of some serious defect pattern will leak into the packet process.
