Embodiment 1

[0014] Such as figure 1 , 2 As shown, the natural green silkworm cocoons to be classified in this embodiment are measured at the same temperature and humidity with a Digieye colorimeter (the temperature and humidity should meet the color measurement at the same time, because different temperature and humidity will affect its color change, as long as all the measurements are completed once). Can be used for color measurement in an environment, using the uniform color space CIELAB color space recommended by the International Institute of Illumination (CIE) in 1976, to measure the lightness L, green / red a, blue / yellow b value of each natural green cocoon , the range of b value measured in natural green silkworm cocoons is [11,65); 2) use the b value measured in step 1) to use the rounding function to start from the minimum value of 5, and take a certain value of 6 as the interval interval, Up to the maximum value of 65, (the rounding function refers to the use of the processing ...

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 [0001] The invention relates to a method for classifying silkworm cocoon colors, in particular to a computer classification method for natural green silkworm cocoon colors. Background technique [0002] Since the cocoon color of natural green silkworm cocoons is the result of the joint action of multiple pigments, the mechanism of pigment metabolism, the degree of influence of various pigments on the color of the cocoon layer, and the explicit and hidden relationship between pigment genes are relatively complicated. During the cocoon and silk reeling process, the color of the cocoon silk is uneven, resulting in poor color effect of the final fabric. In the artificial classification method, due to the difference in the physiological structure of the human eye and the psychological activity of the human being, the error of the classification result is large. This requires a scientific method to classify the color of the natural green silkworm cocoons before coo...
