Cigar fresh leaf automatic grading method based on image recognition

Abstract

The invention relates to an automatic grading method for fresh cigar tobacco leaves based on image recognition, and belongs to the technical field of cigar tobacco leaf production. Fresh cigar leaves to be detected are placed at the feeding port and conveyed to the image recognition system through the tobacco leaf feeding conveyor, the image recognition system starts the camera to collect images of the fresh cigar leaves to be detected, the images are processed, then the images are automatically graded through the tobacco leaf grading model, and the grading result is obtained; and the tobacco leaf feeding conveyor forwards conveys the compared fresh cigar leaves to the balance wheel sorting machine for sorting, and the different grades of fresh cigar leaves are conveyed into different recovery channels. According to the method, the grade of the cigar fresh leaves is judged by using an image recognition technology, automatic sorting is realized, and the grading efficiency and accuracy of the fresh tobacco leaves are effectively improved.

Description

technical field [0001] The invention relates to an image recognition-based automatic grading method for fresh cigar leaves, and relates to the technical field of cigar leaf production. Background technique [0002] The production, planting, modulation, fermentation, grading and rolling of cigar tobacco leaves is an industrial chain with many production links and a long cycle, and it is the inheritance of production experience and technology. The production of cigar leaves in foreign countries such as Cuba, Indonesia and Dominica has a long history. Most of the foreign cigar leaves are planted and operated by farmers, and the production links such as harvesting, drying, grading and fermentation are all in accordance with the unified and mature production technology. The production is carried out according to the regulations, and the technicians are also very professional. Secondly, in the entire cigar production process, large growers or tobacco farmers strictly follow the G...

Problems solved by technology

[0005] The grading of fresh cigar tobacco leaves is closely related to the quality of air-cured and fermented tobacco leaves. The grading of fresh leaves is particularly important. At present, the grading methods of fresh cigar tobacco leaves mainly include basket grading and rod grading. , grading by film, etc., but there are common problems such as large grading errors, low pass rate of grades, and great influence of subjective factors.

Furthermore, fresh cigar leaves should not be left overnight after being harvested. It is required that the tobacco leaves harvested on the same day must be weaved and entered into the drying room for conditioning. Fresh tobacco leaves must be graded and purchased within a short period of time. By employing a large number of grading personnel to sort and grade cigar fresh leaves, it results in high labor costs, inconsistent grading quality, and mixed parts. The grading results are questioned by the main body of the plant, and in serious cases, disputes and contradictions will arise.
