Method for classifying homochromatic furs of homologous animals

Abstract

The invention discloses a method for classifying same-color furs of the same animal, and the method comprises the steps: carrying out the photographing of measured furs for N times, and obtaining N pieces of two-dimensional measured fur image information; sequentially carrying out two-dimensional Fourier transform and column direction summation on each piece of two-dimensional detected fur image information to obtain one-dimensional information, and solving a frequency domain maximum value of the one-dimensional information to obtain detection vectors of N elements; comparing the N elements inthe detection vector with the N elements in the reference vector in pairs to obtain an N * N comparison matrix; if 95% of elements in the contrast matrix are greater than 1 or less than 1, the measured fur and the reference fur do not belong to the same kind of fur, otherwise, the measured fur and the reference fur belong to the same kind of fur. According to the method, a camera is used for photographing, obtained image data is sequentially subjected to two-dimensional Fourier transform and same-column addition to be converted into one-dimensional frequency domain data, the maximum value ofthe one-dimensional data is extracted, the type of the fur is automatically judged according to the frequency domain energy ratio, and unmanned, automatic and rapid classification of the fur is achieved.

Description

technical field [0001] The invention relates to the technical field of fur dyeing, in particular to a method for classifying the same-color fur of the same animal. Background technique [0002] In the fur dyeing industry, different species of fur have significant differences in the absorption of dyes by animal fibers, so they must be dyed with different dye formulations. For the same pure-color fur of the same animal, due to different reasons such as origin, domestication, and wildness, it will cause dense or sparse hair. In the actual dyeing process of fur-like fur, it will be found that there are significant differences in the absorption of dyes between the two, and they are also dyed with different dye formulas. Therefore, it is necessary to classify the pure-colored fur of the same animal before dyeing. [0003] At present, the classification of the pure-color fur of the same animal is roughly classified by the manual touch of the fur by the master worker. It is time-co...

Problems solved by technology

[0003] At present, the classification of the pure-color fur of the same animal is roughly classified by the manual touch of the fur by the master worker. It is time-consuming and labor-intensive for large-scale dyeing, which is an important link that affects the automation of the whole fur dyeing process.

However, there is no relevant report on the classification of the same color fur of the same animal in China.
