Cigar harvesting maturity identification method and system based on ensemble learning

Abstract

The invention discloses a cigar harvesting maturity identification method and system based on integrated learning, and the method comprises the steps: obtaining a to-be-detected cigar image, and carrying out the preprocessing of the to-be-detected cigar image; vectorization dimension reduction is carried out on the preprocessed to-be-detected cigar image, RGB and HSV feature values are extracted, and a feature set is obtained; performing feature dimension reduction on data in the feature set by using a Wrapper packaging algorithm to obtain an initial data set of the to-be-detected cigar image; and inputting the initial data set into the trained random forest model, and outputting a maturity identification result of the cigar image. According to the method, vectorization dimension reduction is carried out on cigar image data, and efficient extraction and utilization of cigar image data information are guaranteed; meanwhile, by means of the advantages of integrated learning, the tobacco leaf texture and color serve as input features of a maturity level identification model, and the problem that data value is damaged is solved; and feature dimension reduction is carried out while feature selection is realized by using a Wrapper packaging algorithm, so that the training cost of the model is reduced.

Description

technical field [0001] The invention relates to the technical field of cigar classification, in particular to a method and system for identifying the maturity of cigar harvesting based on integrated learning. Background technique [0002] The physical and biochemical properties of tobacco leaves grown in the field will change significantly during the development and maturity. The maturity state of cigars at harvest directly determines the quality of tobacco leaves before air-curing, and is closely related to the appearance, internal and sensory quality of tobacco leaves after air-curing. Even for the same variety of tobacco leaves, the difference in maturity will affect the yellowing, color fixing characteristics and water loss characteristics of the cured tobacco leaves, which will affect the quality of tobacco leaves to a certain extent. The premise and foundation of tobacco leaves. [0003] When harvesting cigars, farmers often further subdivide the cigars in different ...

AI Technical Summary

Problems solved by technology

[0004] However, in the production of air-cured tobacco leaves, due to different regions, climate, soil fertility, moisture, cultivation methods, etc. are quite different, and the standards for suitable maturity are different. adversely affect

In addition, most of the agricultural fields still use manual harvesting and naked eye identification of maturity, which is difficult to ensure accuracy and efficiency. The phenomenon of overripe picking in the lower part, raw picking in the middle part, and green picking in the upper part is common, resulting in a decline in the quality of tobacco leaves after air curing and affecting tobacco leaves.
