Abstract

The invention relates to a tipping paper air permeability detection method based on least squares and belongs to the technical field of automation of production and manufacturing of tobaccos. The tipping paper air permeability detection method comprises the following steps: firstly, extracting a hole area of tipping paper through image processing and finding out a relation model of the hole area and the tipping paper air permeability; and determining a relative model of the tipping paper air permeability and the hole area of the tipping paper by using soft measurement of the least squares. With the adoption of the tipping paper air permeability detection method, a detection process of the tipping paper air permeability is clearly and accurately expressed; the goodness of fit and a parameter standard difference reach expected values as much as possible; the least squares is designed to fit the model; a threshold value partitioning algorithm based on an iteration method is used for extracting the hole area of a collected picture; and a calculation result has relatively good balance on precision and complexity.

Description

technical field [0001] The invention relates to a method for detecting air permeability of tipping paper based on least squares, and belongs to the technical field of tobacco production automation. Background technique [0002] At present, the harm of tobacco to human health has become a global problem, and the tobacco industry adopts various methods to detect the amount of tar in cigarettes. Among them, the amount of tar inhaled by smokers is reduced by using tipping paper, and the health hazards of smoking groups are reduced. The air permeability detection of tipping paper is a key technology applied in this industry. [0003] The so-called air permeability (P) refers to the volume of air permeated per unit time, unit area, and unit pressure difference. The international unit is CU. It is the most important index to measure the punching quality of punched tipping paper. [0004] Through the analysis and investigation of the two traditional methods, the Bendtsen method ...
