Embodiment 1

[0027] figure 1 Demonstrated method flow process of the present invention; Carry out image processing (as figure 2 shown), according to image 3 The standard sample size and shape shown in , make a large number of samples, and the standard cigarette sample size and shape description theoretical parameters are shown in Table 1:

[0028]

[0029] Table 1 Theoretical parameter table of standard cigarette sample size and shape description

[0030] The shape description parameters of the standard sample are detected in the CA813 cigarette size and distribution measurement system, and a three-dimensional discrete distribution map is established in the three-dimensional space (in the constructed three-dimensional space, it can be described by three shapes: compactness, slenderness, and rectangularity) One of the parameters is used as the x-axis, and the remaining shape description parameters are used as the y-axis and z-axis respectively, such as the slenderness as the x-axis, ...

Abstract

The invention discloses a method for describing tobacco and square tobacco based on the morphological characteristics of tobacco. The shape description parameters of the tobacco sheets were used to construct a three-dimensional space, and the K-Means algorithm was used to cluster the circular standard tobacco sheets, square standard tobacco sheets, and strip-shaped standard tobacco sheets; the shape description parameters of any irregular tobacco sheets were used Three-dimensional space position P to describe; calculate the Euclidean distance between the three-dimensional space position of the standard cigarette clustering center point to the irregular cigarette shape description parameter, and combine the area parameter to describe the morphological characteristics of the irregular tobacco sheet; according to Description of the morphological characteristics of irregular laminar tobacco, and classification of irregular laminar tobacco. The invention fills up the gap in the current description of the shape of the tobacco laminae, facilitates the provision of a basis for the research on the shape of the tobacco lamination in the process of processing blades such as tobacco shredded structure, and realizes the classification of the shape of the irregular tobacco laminae.

Description

technical field [0001] The invention belongs to the field of tobacco structure, and in particular relates to a method for describing and classifying laminae based on the morphological characteristics of laminar tobacco. Background technique [0002] In recent years, tobacco processing technology has developed rapidly, and the level of processing technology has been continuously improved, but basic research is still relatively weak. In the stages of threshing and redrying (tobacco leaves→leaves) and shredding (leaves→shredded tobacco), the shape of tobacco leaves has attracted more and more attention. [0003] Lamina is a mixture of leaves of different sizes and irregular shapes. The morphological characteristics of lamina have obvious influence on the structure of shredded tobacco, among which the area of ​​lamella has a great influence. There have been many research results in this field, but in actual production and application, it is found that the proportioning schemes ...
