Embodiment Construction
[0020] The present invention will further illustrate the calculation method and process of the shredded tobacco curl index in conjunction with the accompanying drawings:
[0021] (1) Take a small amount of shredded tobacco to be tested and place it on the material imaging platform, spread each shredded tobacco horizontally one by one and ensure that there is no overlap between each shredded tobacco;
[0022] (2) The image acquisition system performs image acquisition on the shredded tobacco on the material imaging platform, and transmits and saves the acquired image to the computer;
[0023] (3) The image processing system in the computer uses the image segmentation algorithm to process the acquired image, extracts the shredded tobacco skeleton after imaging, and can obtain the following figure 1 The tobacco skeleton image shown.
[0024] (4) Advance from one end of the shredded tobacco to the other end in units of pixels, sequentially connect the corresponding pixels in the ...

A cigarette cut tobacco crimpness quantification characterization method is featured in that the method carries out quantification analysis for pixels in an acquired cut tobacco image, makes statistics for color component gray scale distribution differences between a target and the background, and uses a threshold segmentation method based on the RGB component difference to segment the image colorspace, thus extracting the cut tobacco contour in the image, using an iteration algorithm to determine a cut tobacco geometry skeleton in a figure, calculating a cut tobacco skeleton length, i.e., the cut tobacco length, and further quantitatively characterizing the cut tobacco crimpness. The advantages are that 1, the method uses an imagery method to determine the cut tobacco crimpness index, and the determination process is simple and efficient; 2, the crimpness index defined by the method can well characterize the cut tobacco curling degree; 3, the method can quantitatively analyze the cuttobacco curling degree, and can provide guidance basis for improving and optimizing parameter conditions of different cut tobacco making processes.
Description
technical field [0001] The invention relates to the technical field of tobacco processing, in particular to a method for quantitatively characterizing the curl degree of shredded tobacco of cigarettes. Background technique [0002] In cigarette production, the morphology and structure of shredded tobacco is one of the main factors affecting the filling capacity of shredded tobacco and the quality of cigarette crimping. Under the condition of the same specification and hardness of cigarettes, the filling capacity of shredded tobacco is closely related to the weight of cigarettes. , and is closely related to the amount of tar released from cigarette smoke and the sensory quality. The degree of curling of shredded tobacco is an important parameter reflecting the morphological structure of shredded tobacco, and is also an important physical index affecting the filling capacity of shredded tobacco. The greater the degree of curling of shredded tobacco, the greater the filling cap...
