Description

A kind of leaf of beating based on double spectral techniques goes stalk quality detection device and detection method
Technical field
Material detection technique field in being processed the present invention relates to tobacco, more particularly to a kind of beating based on double spectral techniques Leaf goes stalk quality comprehensive detection device and detection method.
Background technology
Tobacco leaf is made of offal and blade two parts, and the thick and stiff vein of tobacco leaf is known as offal, and weight accounting is about tobacco leaf 25%~30%.Leaf of beating in tobacco threshing redrying technique goes the top priority of stalk process exactly to be allowed by special equipment per a piece of Blade and the offal separation of tobacco leaf, its blade portions are separated into the piece cigarette that size does not wait, and offal is partially separated into length Different offal section, to meet follow-up classification processing request.
According to tobacco business standard YC/T146-2010《Tobacco threshing and redrying technological specification》, weigh and beat leaf and go to obstruct quality Refer mainly to indicate rate containing leaf in rate containing stalk in blade construction, leaf, long stalk rate, stalk.The four indices are sampling detection, and physics is anticipated Justice is weight accounting, as blade construction refers to large stretch of, middle, the weight accounting of small pieces, fragment, powder each in the sample.Its Blade of the testing requirements of two indexs of rate containing stalk after beating leaf and removing stalk collects in middle blade construction and leaf samples on conveyer belt (3000 ± 300) g, by different special mechanical equipments and by manually calculating result;And rate containing leaf in long stalk rate and stalk The detection of two indexs then requires the offal after beating leaf and removing stalk to collect sampling (1000~1500) g on conveyer belt, then passes through four Sample is reduced to (80~120) g by point-score, then by manual measurement and calculates result.The detection process of each single item index is all It is time-consuming and laborious, and index is more single, only one i.e. weight accounting.In its middle period the detection of the rate containing stalk in order to make blade and Offal therein is completely separated, and blade is all smashed, belongs to destructive detection, causes substantial amounts of tobacco leaf to be lost.
In recent years, with the rapid development of machine vision technique, in tobacco business, lossless detection method is begun one's study to take Traditional destructive detection method is formed, the situation of wastage of material in detection process is reduced, so as to reduce cost.Then it is various to be based on The detection means of image method continuously emerges, but the equipment developed at present has two deficiencies, first, the blade construction detected, Ye Zhong The four indices of rate containing leaf in rate containing stalk, long stalk rate, stalk, are respectively necessary for corresponding four kinds of equipment to complete, do not possess one-machine-multi-function The advantages of, detection device is invested into higher;Second, rate containing stalk and the existing image of the two indices of rate containing leaf in stalk are known in current leaf Not lossless inspection technology for detection resultant error is larger, it is impossible to adapts to production requirement very well.
Detection for blade construction and long stalk rate is since detection object is single, because the method is relatively easy:Such as use face Product ratio.Because for single detection object, no matter using weight ratio, area ratio or volume ratio, the ratio of three is equal , therefore no matter any statistical method is used, all it is equivalent in theory, because the weight per unit area or list of detection object Position volume weight is unrelated with its size, this point is approved and uniformly at present in tobacco business.
Situation is just different for the index of rate containing leaf in Ye Zhonghan stalks rate and stalk, and computational methods are relative complex, here It is related to two kinds of different materials of density:Blade and offal, it is therefore necessary to the shape facility ruler such as area for collecting image method Reliability that is very little to be converted into weight, then asking weight ratio to improve detection data, preferably meets current tobacco business requirement.
The Chinese invention patent of Application No. 201110213062.7 discloses a kind of Ye Zhonghan based on combination x ray fluoroscopy x Stalk and the visual recognition detection method of rate containing stalk, the saturating of tobacco leaf is obtained by the combined light source and CCD camera for the tobacco leaf both sides that are placed in Visible image, then identifies the shape ruler of offal and blade, extraction blade and offal according to characteristics of image designed image Processing Algorithm Very little feature simultaneously calculates rate containing stalk in leaf.The Chinese invention patent of Application No. 201210475963.8 discloses a kind of based on actively The infrared imaging detection method containing stalk in the leaf of heating;Its step is similar with 201110213062.7, and difference lies in obtain image Method and image processing algorithm are different, it utilizes the thermal radiation phenomena of tobacco leaf, by the way that to tobacco leaf, actively heating makes blade and offal The temperature difference is produced, then image is gathered with infrared thermography and identifies blade and offal with image processing algorithm, Calculate the rate containing stalk of tobacco leaf.
The Chinese invention patent of Application No. 201310069611.7 is disclosed in a kind of leaf discrete based on high-speed flow Containing stalk and beat leaf parameter detecting elimination method, discrete mainly by high-speed flow, and the mode of its acquisition fluoroscopy images of tobacco leaf It is consistent with 201110213062.7, by analyzing the tobacco leaf fluoroscopy images obtained, textural characteristics are extracted, using binary tree Blade and offal are accurately distinguished, the tobacco leaf containing offal is rejected, while calculates tobacco leaf area, and then acquisition Percentage of large and middle size strips, Rate containing stalk etc. beats leaf parameter in small pieces rate and leaf.These three methods are required to distinguish blade and offal in same piece image, by mistake Difference is larger.In addition during rate containing stalk in calculating leaf, it is also necessary to knowing the density of offal and blade could solve, and due to Different cultivars, grade, the place of production, the density of its blade of the tobacco leaf of moisture content and offal are different, therefore there is no this in industry at present Class data, are used to lack operability when calculating rate containing stalk in leaf in these processes.
The Chinese invention patent of Application No. 201410302230.3 discloses a kind of leaf based on EO-1 hyperion and is detected containing stalk Device, emphasis are described the structure and composition of device, but EO-1 hyperion are not further described, do not refer to as What distinguishes the computational methods of the rate containing stalk in blade and offal and leaf.
The Chinese invention patent of Application No. 201410061575.4 discloses a kind of tobacco leaf rate containing stalk assay method, application Number a kind of tobacco leaf rate containing stalk measurement device is disclosed for 201420078131.7 Chinese utility model patent, filled by X-ray Put the fluoroscopy images for obtaining offal and then obtain the area or volume of offal, the acquisition of its tobacco stalk quality there are three kinds of methods:When The offal area density obtained with prior survey calculation is multiplied by be obtained by the offal area of image acquisition;Second, measured with prior The offal bulk density being calculated is multiplied by be obtained by the offal volume of image acquisition;Third, penetrated according to the thickness of offal with X There are correlation between line penetrability:I, I in formula0For X-ray intensity before and after decay, A is rubbing for atom Your quality, σ accumulate for atomic cross section, and N is constant, ρ is offal density, x for offal thickness, as can be seen from the above equation ray decline The density for subtracting and being tested offal is multiplied by thickness i.e. ρ x and has certain mathematical relationship.And the attenuation change of ray can be embodied in cigarette On the gray level image of stalk, the change of gray value is shown as, the corresponding gray value of the bigger pixel of ρ x values is smaller, and ρ x values are smaller The corresponding gray value of pixel is bigger.The area density of gray scale and offal can be subjected to area using the gray scale and ρ x relationships of the above Between it is corresponding:Such as [0-30]-P1、[30-60]—P2、[60-90]—P3、[90-120]—P4…[210-255]—P8, P1…P8 It is illustrated respectively in the offal area density in corresponding grey scale section;If that the area in corresponding grey scale section is respectively S1、S2…S8, Then tobacco stalk quality m=P1×S1+P2×S2+…P8×S8;Tobacco stalk quality again divided by by weighting manner obtain quality of tobacco be Rate containing stalk in leaf can be tried to achieve.This two patent is disadvantageous in that:First, the acquisition of offal area density and bulk density needs to carry Preceding independent measurement calculates, and with the measurement process of the rate containing stalk in leaf and asynchronous, process is cumbersome and error is larger;Secondly, penetrated based on X The tobacco stalk quality computational methods of line attenuation are a bit forced, and it is true that the density of the decay of ray and detected offal is multiplied by the i.e. ρ x of thickness Real storage is in certain mathematical relationship, i.e., offal gradation of image is with ρ x there are correspondence, but ρ x are not the area density of offal, because This is similar to tobacco stalk quality m=P1×S1+P2×S2+…P8×S8This computational methods are worthless.
