TWO-DIMENSIONAL CODE SPRAY PRINTING INFORMATION ASSOCIATION DETECTION DEVICE BASED ON CIGARETTE PACKET RECOGNITION

摘要

Two-dimensional code plays an important role in the tobacco industry. In this study, the recognition and correlation detection of two-dimensional code spray printing information were studied, and a two-dimensional code association detection device was designed, which could realize the recognition of two-dimensional code on the cigarette packet and the detection of packet-bar association. The device was tested. After two tests, it was found that the recognition rate of cigarette packet reached 99.46% and 99.97%, respectively; most of the unrecognized cases were caused by operation errors; the correct rate of packet-bar association reached 100%; the correct packet-bar association could also be realized under three artificial abnormal conditions. The test results show that the device has excellent accuracy and stability and can be further applied in practice.
