5) The text and graphics on the cigarette package are superimposed, and the text and graphics are superimposed together, which is not easy to identify
Because among the 32 laser code characters, the 4-bit characters customized by each region can be letters, numbers, and most of them are letters (custom codes), the letters here can be either uppercase letters or lowercase letters, and the uppercase letters There are 26 letters, 26 lowercase letters, and the shapes of various letters are quite different in practice, which makes the image recognition process very complicated, the amount of calculation is huge, and it is very error-prone. The error probability of these 4 characters is very high. Every new wrong recognition will lead to the accumulation of recognition errors, which in turn will increase the difficulty in the subsequent image recognition and comparison. Time Efficiency Requirements

Embodiment approach 1

[0033] See figure 1 , 2(a) And 2(b), the tobacco laser code assisted identification method provided by the present invention, the tobacco laser code includes digital serial numbers and custom characters, and the first described tobacco laser code assisted identification method includes the following steps:

[0034] S10. Add a segmentation mark between the custom characters of the tobacco laser code of the cigarette and the digits of the digital serial number after the custom characters;

[0035] S20. Obtain an image including the tobacco laser code of the cigarette and the segmentation mark;

[0036] S30. Identify the digital serial number in the image according to a preset sequence, and when the position of the custom character is recognized, use the segmentation mark as the starting position to identify the digital serial number located in the self-defined character position. The number after the defined character.

[0037] In the tobacco laser code-assisted recognition m...

Embodiment approach 2

[0058] Please refer to Fig. 3(a), the present invention also provides a tobacco laser code auxiliary identification device, including:

[0059] Segmentation mark adding module 1, for adding a segmentation mark between the custom characters of the tobacco laser code of the cigarette and the number after the digital serial number after the custom characters;

Abstract

The invention discloses a tobacco laser code auxiliary identification method, device and tobacco laser code identification equipment. The tobacco laser code assisted identification method includes the following steps: S10, adding a segmentation mark between the custom characters of the tobacco laser code of the cigarette and the number after the digital serial number after the custom characters; S20, obtaining all the The tobacco laser code of the cigarette and the image of the segmentation mark; S30, identify the digital serial number in the image in a preset order, and when the position of the custom character is recognized, use the segmentation mark as The starting position, identifying the number after the user-defined character in the digital serial number. The tobacco laser code assisted recognition method, device and tobacco laser code recognition equipment of the present invention are simple and accurate for tobacco laser code recognition, simplifies the amount of data processing, and can meet the requirements for recognition efficiency and accuracy when a large number of tobacco laser codes need to be recognized .

Description

technical field [0001] The invention relates to the technical field of visual recognition of tobacco rods, in particular to a tobacco laser code-assisted recognition method, device and tobacco laser code recognition equipment. Background technique [0002] According to the national tobacco monopoly system, cigarettes circulating in the cigarette retail market should be purchased from local tobacco companies that have obtained a tobacco wholesale license according to law, and the local Tobacco Monopoly Bureau is responsible for market supervision according to law. In order to safeguard national interests, maintain the normal order of cigarette business, and facilitate the management of the local Tobacco Monopoly Bureau according to law, the State Tobacco Monopoly Administration requires tobacco companies in all regions to laser print a "32-digit code segment" on each cigarette sold. Composed of letters and letters, with a special source of information, it can help monopoly la...
