Abstract
The invention discloses a measuring method for shredding width. According to the method, digital processing is carried out on a pre-processing image by using a matlab image processing method, a binaryzation image is extracted and then the shredding width is calculated; specifically, the measuring method comprises the following steps of: a, firstly, sampling three samples and pasting the three samples on a background template; b, acquiring the pre-processing image for an analysis by using a digital camera; c, finally, carrying out digital processing to the pre-processing image by using the matlab image processing method, extracting the binaryzation image and calculating an average width, wherein a specific calculation formula for the shredding width is shown in the specification. The measuring method for the shredding width disclosed by the invention solves the problem that accurate measurement of the shredding width is difficult to realize in present cigarette enterprises, a simple and feasible measuring method is provided for an accurate, objective, simple and efficient evaluation of the shredding width, reliable technical parameters and evaluation data are provided, and a significance is provided for controlling stability of a production process, uniformity of the shredding width and quality indexes of cigarettes.
Description
Technical field
The present invention relates to cigarette product quality monitoring field, especially in the production of cigarettes process, the method for supervising of product quality management, specifically a kind of tobacco cut width assay method based on the matlab image processing method.
Background technology
In the production of cigarettes process, can be in time, the homogeneity and the stability of monitoring product exactly, to improving the cigarette product quality significance is arranged.At present, domestic most of cigarette enterprise can only detect the end product of cigarette, lacks monitoring and measuring means accurately for the process control precision.The organoleptic quality of the uniform and stable and cigarette product of tobacco cut width and the stability of fume indication have higher relevance; Tobacco cut width is one of key factor that influences cigarette product inherent quality stability; The instability of tobacco cut width; Can cause the variation of cigarette smoke components in combustion process, influence the odor characteristic and the mouthfeel characteristic of cigarette, even cause the drift of cigarette style and features.
At present; The pipe tobacco projector (JTY250-1 or EP-1 profile projectors) that adopt are measured the pipe tobacco width more in the industry, this method at first when sampling, the pipe tobacco of surveying under-represented; What select all is the pipe tobacco of both sides chopping comparison rule; What read only is the data of opposing parallel position, a certain section both sides of pipe tobacco, and for curling, jagged pipe tobacco is powerless; When using this method to measure the pipe tobacco width in addition, take time and effort, different detection personnel have the different operation custom, cause personal error bigger.Therefore, the assay method of setting up tobacco cut width has very important meaning.
Summary of the invention
The purpose of this invention is to provide a kind of assay method that can reflect the chopping actual width succinctly, efficiently.
For solving the problems of the technologies described above, the invention provides a kind of tobacco cut width assay method, use the matlab image processing method that the pre-service picture is carried out digitized processing, extract binary image, calculate tobacco cut width, specifically comprise the steps:
A, at first uses sampling bag to get the 50g pipe tobacco after the chopping operation, and picking out does not have adhesion and length to reach 30 in the above pipe tobacco of 2cm, and 30 pipe tobaccos and contrast template are accordinged to nonoverlapping principle, uses respectively that solid gum is open and flat to be pasted on the background template;
B, the background template that will paste pipe tobacco and contrast template are placed horizontally on the shooting operation platform; In the uniform environment of illumination condition, open four corner lamp sources; Use digital camera adjustment focal length; Close flashlamp, directly over said shooting operation platform, vertically take pictures, obtain to analyze and use the pre-service picture;
C, use the matlab image processing method that the pre-service picture is carried out digitized processing at last, extract binary image, and extract s

As optimal technical scheme of the present invention, in step a, said background template is a smooth abrasion-proof opaque and white plastic plate, and said contrast template is the green plastic thin plates of length and width at 3-5cm; In step b, use digital camera directly over said shooting operation platform, vertically to take pictures at the 40cm place.
Beneficial effect of the present invention:
The invention solves present cigarette enterprise and accurately measure the difficult problem of tobacco cut width; For accurate, objective, succinct, efficient evaluations tobacco cut width provide a kind of simple and feasible assay method; And reliable technique parameter and evaluating data are provided, all significant for control stable production process property, tobacco cut width homogeneity and cigarette quality index.

Embodiment
Specify optimal technical scheme of the present invention below in conjunction with accompanying drawing.
Tobacco cut width assay method of the present invention uses the matlab image processing method that the pre-service picture is carried out digitized processing, extracts binary image, calculates tobacco cut width, specifically comprises the steps:
A, at first; After the chopping operation, use sampling bag to get the 50g pipe tobacco; Picking out does not have adhesion and length to reach 30 in the above pipe tobacco of 2cm, and 30 pipe tobaccos and contrast template are accordinged to nonoverlapping principle, uses respectively that solid gum is open and flat to be pasted on the background template; Said background template is a smooth abrasion-proof opaque and white plastic plate, and said contrast template is the green plastic thin plates of length and width at 3-5cm;
B, the background template that will paste pipe tobacco and contrast template are placed horizontally on the shooting operation platform; In the uniform environment of illumination condition, open four corner lamp sources; Use digital camera adjustment focal length; Close flashlamp, vertically take pictures in the 40cm place directly over said shooting operation platform, obtains to analyze to use the pre-service picture;
C, use the matlab image processing method that the pre-service picture is carried out digitized processing at last, extract binary image, and extract s
iAnd l
iData, according to contrast template known dimensions P
0And S
0Calculate the mean breadth of 30 pipe tobaccos, wherein the concrete computing formula of tobacco cut width is:
Because the width of a pipe tobacco is irregular, unfixed; But the length of a pipe tobacco is relatively-stationary; So the present invention uses the matlab image processing method; Extract the area of pipe tobacco, use second order center long axis of ellipse length to represent the length of pipe tobacco, converting through contrast template at last draws the pipe tobacco width.
