Abstract

The invention provides an online numerical identification method for tobacco leaf color, comprising: collecting original tobacco leaf images of tobacco leaf samples produced online; processing the original tobacco leaf images correspondingly to extract Munsell signals of the tobacco leaf samples produced online; The Munsell signal of the tobacco leaf samples is continuously projected; the tobacco leaf color projection eigenvalues ​​of the tobacco leaf samples produced online are calculated; the second classification is performed on the online tobacco leaf samples according to the tobacco leaf color projection eigenvalues; the first classification and the second classification are judged. Whether the secondary classification is consistent; if it is, it means that the classification is successful, and the process ends; if not, it means that the classification fails, and the collection step is returned. The invention quickly extracts the real information of tobacco leaves, and has strong consistency with manual scoring; realizes fast and accurate detection of industrial cameras; reduces the sample workload of tobacco leaves; It has strong reference significance for qualitative theory and quantification.

Description

technical field [0001] The invention belongs to the field of tobacco product production, and relates to an identification method, in particular to an online numerical identification method of tobacco leaf color. Background technique [0002] The quality of tobacco leaves mainly includes the appearance quality of tobacco leaves, the sensory evaluation quality of tobacco leaves, the physical quality of tobacco leaves, the coordination of chemical components of tobacco leaves, the availability of tobacco leaves and the compatibility of tobacco leaves; the color of flue-cured tobacco leaves and the chemical composition of tobacco leaves There is a significant correlation between nicotine and total sugar, and also a very significant correlation with the aroma quality and aroma quality of sensory evaluation; the color of tobacco leaves can basically reflect the quality of tobacco leaves; the color of flue-cured tobacco is an important part of the appearance quality of tobacco leave...
