Embodiment

[0033] A kind of laminar cigarette rating method of the present embodiment, its flow process comprises:

[0034] S1. Take a tobacco leaf sample and spread the tobacco leaf sample flat. Tobacco leaf samples are generally fragmented lamellar tobacco, and the purpose of tiling is to make the calculation of the area ratio of various colors accurate, and to avoid the calculation error of the area ratio caused by partial fragments being covered.

[0035] S2. Acquiring image data of the tobacco leaf sample after being tiled. Specifically, the image data of the tobacco leaf sample can be captured from the top of the laid tobacco leaf sample using an image acquisition device.

[0036] S3. Obtain the area ratios of various basic colors and non-basic colors of the tobacco leaf sample in the image data. In the case of tiling, the area ratios of the various colors of the tobacco leaves can represent the weight ratios of the various colors of the tobacco leaves, so that there is no need t...

Abstract

The invention relates to a tobacco lamina rating method which comprises the following steps: S1, taking a tobacco leaf sample, and flatly paving the tobacco leaf sample; s2, collecting image data of the tiled tobacco leaf sample; s3, collecting area proportions of various basic colors and non-basic colors of the tobacco leaf sample in the image data; and S4, rating the tobacco leaf sample according to the area proportion. According to the tobacco lamina rating method, calculation of the weight proportion of the tobacco leaf fragments of all the colors is replaced with the area proportion of the tobacco leaf fragments of all the basic colors and the non-basic colors, implementation on an automatic system is easier, manpower is saved, and the method is more accurate.

Description

technical field [0001] The invention belongs to the technical field of tobacco leaf rating, and in particular relates to a tobacco rating method and system. Background technique [0002] There are many processes in the production of cigarette products, and various factors (such as labor, machine errors, materials, methods) will fluctuate during the production process, and it is impossible to guarantee that each process is always in a stable technical state, so there must be certain quality fluctuations . Therefore, when tobacco leaf products are stored and purchased, they must pass strict quality inspections, reject unqualified materials and isolate them, and unqualified materials and intermediate products will not be transferred or released to prevent unqualified materials from being put into production. [0003] Laminar tobacco is the fragmented leaves after removing stems from tobacco leaves. It is the main raw material required for the production of cigarette products. ...
