Abstract
A tobacco leaf grading method includes the following steps: (1) creation of a tobacco leaf grading standard database; (2) grading of tobacco leaves. The grading method adopted by the invention can quickly and effectively grade tobacco leaves, decrease labor intensity, reduce labor cost and increase grading precision and grading quality. Because the standard tobacco leaf feature database is created in grading, the feature data of tobacco leaves can be conveniently compared, so that the grades of tobacco leaves can be determined. Because the Visual C++6.0 technique is used, a programming software program can be effectively utilized to analyze and identify the individual features of tobacco leaves, so that tobacco leaves can be graded. Because the OPENCV function library is called in Visual C++6.0 programming, the complexity of the program is decreased, the running speed of the program is increased, and thereby the tobacco leaf grading speed is increased. In addition, the adoption of the sequential comparison method decreases the probability of errors in grading and increases the precision and accuracy of grading.
Description
Technical field
The present invention relates to a kind of stage division, especially relate to a kind of tobacco leaf grading method.
Background technology
Tobacco is a kind of important industrial crops, very extensive in the cultivated area of China, and closely related with people's life.Wherein tobacco leaf is the important raw and processed materials of China's Cigarette Manufacturing Industry, occupies very large proportion in the national economy of China, and therefore we must improve constantly the economic worth of tobacco leaf.
Owing to being subject to different geographical weather, environment, soil and kind, inserted part, the impact of plant measure and baking process, the mass discrepancy of tobacco leaf is very large, therefore we must carry out necessary classification to tobacco leaf, determine the different quality grade of tobacco leaf, divide with class, determine the price with matter, make rational use of resources, to adapt to the demand of agricultural and economic development.In China, the tobacco leaf of same producing region and kind is mainly judged and classification by aspects such as its maturity, identity, oil content, blade construction, colourity, length and residual wounds.For a long time, quality testing and the classification of China's tobacco business to cured tobacco leaf all judged with people's organoleptic detection result and expertise.Along with to the improving constantly of tobacco product quality requirement, China starts to promote 42 grades of new standards, but the manual grading skill mode efficiency of this organoleptic detection and subjective assessment is low, labour intensity is large, and labor intensive is many, and is easily subject to the impact of artificial subjective factor, effectiveness of classification is low, and classification is of poor quality.
Summary of the invention
The object of the invention is for solving manual grading skill tobacco leaf labour intensity large, the low problem of effectiveness of classification simultaneously, a kind of tobacco leaf grading method is provided, the stage division that the present invention adopts can carry out classification to tobacco leaf quickly and efficiently, reduce artificial intensity, reduce labour cost, improved effectiveness of classification and classification quality.In classification, Criterion tobacco leaf property data base, has facilitated tobacco leaf has been carried out to characteristic contrast, thereby determines its grade.Use Visual C++6.0 technology, effectively utilize programming software program indivedual features of tobacco leaf are analyzed and distinguished, thereby tobacco leaf is carried out to classification.In Visual C++6.0 programming, call OPENCV function library, reduced the complexity of program, improved the speed of service of program, thereby improved the hierarchical speed of tobacco leaf.Adopt in addition this method of contrast successively, reduced the wrong possibility occurring in classification, improved accuracy and the accuracy of classification.
The present invention is the deficiency solving the problems of the technologies described above, and the technical scheme adopting is:
A kind of tobacco leaf grading method, comprises the following steps:
One, create tobacco leaf grading standard database;
1., collect the tobacco leaf of various criterion grade, then the tobacco leaf of each standard class is taken pictures and digital picture is input in computer;
2., by computer, the tobacco leaf image of each standard class is processed and is analyzed, and extract the characteristic parameter of tobacco leaf;
3., the characteristic parameter of each standard class tobacco leaf extracting is stored in the tobacco leaf grading standard database of foundation in corresponding tables of data, form a complete tobacco leaf grading standard database;
Two, tobacco leaf grading processing;
1., gather the pictorial information of tobacco leaf to be detected and be input in computer;
2., by computer, tobacco leaf picture is carried out to pretreatment, and further extract tobacco leaf characteristic parameter;
3., computer visual image processed to hierarchy system be connected to tobacco leaf grading standard database, and according to this with database in the tobacco leaf main characteristic parameters of each various criterion grade contrast, determine whether tobacco leaf belongs to this grade;
4., determine after tobacco leaf grade to be detected, send graded signal in PLC control system, by PLC control system, tobacco leaf to be detected is delivered in the collection basket of corresponding grade.
PLC control system described in step 2 is the PLC control system of corresponding tobacco leaf sorter.
The invention has the beneficial effects as follows: the stage division that the present invention adopts can carry out classification to tobacco leaf quickly and efficiently, reduces artificial intensity, reduce labour cost, improved effectiveness of classification and classification quality.In classification, Criterion tobacco leaf property data base, has facilitated tobacco leaf has been carried out to characteristic contrast, thereby determines its grade.Use Visual C++6.0 technology, effectively utilize programming software program indivedual features of tobacco leaf are analyzed and distinguished, thereby tobacco leaf is carried out to classification.In Visual C++6.0 programming, call OPENCV function library, reduced the complexity of program, improved the speed of service of program, thereby improved the hierarchical speed of tobacco leaf.Adopt in addition this method of contrast successively, reduced the wrong possibility occurring in classification, improved accuracy and the accuracy of classification.
