Embodiment Construction

[0020] Such as figure 1 and figure 2 As shown, the 32-bit barcode collection system for cigarettes according to an embodiment of the present invention includes a workbench 1 on which a conveying track 2 for conveying inspected cigarettes is installed. A camera 3 and a position sensor 5 are fixed, and the camera is electrically connected to the image acquisition card; the image acquisition card is electrically connected to the vision server; the camera is electrically connected to the position sensor; a light source is also fixed on the conveyor track 4. The light source 4 is electrically connected to the image acquisition card.

[0021] In the system of the present invention, obtaining a high-quality processable image is the key to correctly identify the 32-bit barcode. For the system to be successful, it must first ensure that the image quality is good and the features are distinct. Often the failure of a machine vision project is mostly due to poor image quality and unob...

Abstract

The invention discloses a cigarette case 32-bit bar code acquisition system and a 32-bit bar code identification method. The 32-bit bar code identification method comprises the following steps that: a bar code image is acquired by the cigarette case 32-bit bar code acquisition system; the bar code image is subjected to image pre-processing, a character feature extraction and comparative identification; and the bar code image is subjected to manual correction, such that wrongly-identified characters are corrected, and a result is outputted. The cigarette case 32-bit bar code acquisition system of the invention is of structural simplicity, and can automatically and quickly acquire bar code images of cigarette cases in a batched manner under complex environments. With the 32-bit bar code identification method of the invention adopted, code copying speed and code copying accuracy of the tobacco industry can be improved, and cigarette case record filing management can be facilitated.

Description

technical field [0001] The invention relates to a 32-bit barcode collection system and a 32-bit barcode identification method for cigarette sticks. Background technique [0002] Monopoly personnel are the center of the tobacco company's external supervision services, and each monopoly personnel is the image representative of the company's external supervision. Currently, for the confiscated cigarettes in the market, the monopoly personnel use paper records to transcribe the barcode, causing the monopoly personnel to work. The volume is large, the work efficiency is low, and there is a considerable error rate, and the final paper document is not conducive to the summary statistics of the time period. How to effectively help monopoly personnel to carry out better and faster barcode recording and management of confiscated cigarettes, so that monopoly personnel can have more energy in the promotion of tobacco laws and regulations and market management, is also an urgent need for...
