Abstract
The invention discloses a computer classification method for colors of natural green silkworm cocoons. The method comprises the following steps: step 1, measuring the colors of the natural green silkworm cocoons to be classified through a color measurer, detecting the lightness L (i.e., the values of green/red a and blue/yellow b,) of each natural green silkworm cocoon by adopting a CIELAB color space, and finding the maximum value and the minimum value of the b value of the natural green silkworm cocoon; and step 2, taking fixed values as the interval starting from the minimum value of the b value measured in the step 1 with a rounding function until the maximum value, wherein the silkworm cocoons with b values in the same interval belong to the same variety. The method overcomes the problem of great errors in the classification results due to the inaccurate manual classification, and has the advantages of short classification time, high accuracy, simplicity in operation, strong science and the like.
Description
Technical field
The present invention relates to a kind of method of silk cocoon color classification, especially a kind of computer classification method of natural green silk cocoon color.
Background technology
Cocoon look colour generation due to natural green silk cocoon is the coefficient result of multiple pigment, metabolism of pigment mechanism, various pigment are to more complicated such as the aobvious hidden relations between the influence degree of cocoon layer colour generation, chromogene, in the cocoon cooking of natural green silk cocoon, silk reeling process, cause its silk unevenness of tint, cause the color effect of final fabric not good.Cause the error of classification results large because the physiological structure of human eye is different with the psychological activity of people in artificial system, this just needs a kind of method of science to carry out color classification to natural green silk cocoon before cocoon cooking, and can manpower be saved in assorting process, increase economic efficiency.
The content of invention
The object of the present invention is to provide a kind of computer classification method of natural green silk cocoon color, the inaccurate error of classification results that causes overcoming manual sort is large, and have the classification time short, accuracy is high, the simple to operate and scientific advantage such as by force.
For achieving the above object, technical scheme of the present invention is:
A kind of computer classification method of natural green silk cocoon color, comprise the following steps: the natural green silk cocoon colour photometer 1) will classified carries out colour examining, adopt the CIELAB color space, measure the value of the lightness L of each natural green silk cocoon, green/red a, indigo plant/yellow b, find out maximal value and the minimum value of natural green silk cocoon b value; 2) by the b value bracket function that records in described step 1) from minimum value, getting certain value is interval, until maximal value, the silk cocoon of b value in same interval is same kind.
Natural green silk cocoon in described step 1) is same once all colour examinings in same temperature and same humidity environment.
The computer classification method of described a kind of natural green silk cocoon color, is characterized in that the colour photometer of described step 1) adopts Digieye colour photometer, selects the CIELAB color space.
Described step 2) interval be 6.
Described step 2) in be divided into of a sort natural green silk cocoon to be recorded by colour photometer lightness L, green/red a, the value of indigo plant/yellow b and such lightness L, green/red a, indigo plant/yellow b the aberration of mean value be no more than 1.8.
Described aberration adopts Patchtool choice of software Colorimetry formula CIE2000 to calculate.The invention has the beneficial effects as follows: the computer classification method of a kind of natural green silk cocoon color that the application of the invention provides, be suitable for the assorting process of natural green silk cocoon before cocoon cooking, filature, overcome the uneven color causing green silk cocoon subsequent product in artificial system because the physiological structure of human eye is different with the psychological activity of people, there is the classification time short, accuracy is high, simple to operate and the scientific advantage such as by force, the natural green silk cocoon of the various depth that may be used for classifying.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the natural green silk cocoon that the present invention uses;
Fig. 2 is the schematic diagram of all kinds of natural green silk cocoon after the present invention classifies.
Embodiment
Embodiment 1
As shown in Figure 1, 2, the natural green silk cocoon Digieye colour photometer that the present embodiment will be classified is in same temperature and the (colour examining while that epidemic disaster will meeting of same humidity, because different humitures can affect the change of its color, as long as once all surveyed just can) environment in carry out colour examining, adopt international lighting association (CIE) the uniform colour space CIELAB color space of recommending in 1976, measure the value of the lightness L of each natural green silk cocoon, green/red a, indigo plant/yellow b, the scope recording natural green silk cocoon b value for [11,65); 2) by the b value bracket function that records in described step 1) from minimum value 5, get certain value 6 for interval, until maximal value 65, (bracket function refer to utilize as in Microsoft Excel in the process of numeral, often round by the figure place of specifying as required, the minimum value such as recording b is 5.6, has been just 5 with bracket function after rounding).The silk cocoon of b value in same interval 6 is same kind.Obtain the kind coldest days of the year end, b value scope is respectively b
kind one: [11,17), b
kind two: [17,23), b
kind three: [23,29), b
kind four: [29,35), b
kind five: [35,41), b
kind six: [41,47), b
kind seven: [47,53), b
kind eight: [53,59), b
kind nine: [59,65).(note: left side end value can be got, the right end value can not be got); When b is 17, belong to kind 2 and adopt that Patchtool choice of software Colorimetry formula CIE2000 calculates the lightness L of the single natural green silk cocoon of same kind, green/red a, the value of indigo plant/yellow b and such natural green silk cocoon lightness L, green/red a, aberration that indigo plant/mean value calculation of yellow b obtains are no more than 1.8, aberration is greater than 1.8 and is considered as error.(aberration selects known CIE2000 colour difference formula to calculate), the error that different cultivars calculates is in table 1.
The natural green chromatic cocoon that shade can be differed by the present embodiment is classified exactly, overcome the uneven color causing green silk cocoon subsequent product in artificial system because the physiological structure of human eye is different with the psychological activity of people, there is the classification time short, accuracy is high, simple to operate and the scientific advantage such as by force, the natural green silk cocoon of the various depth that may be used for classifying.
Table 1
