Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings.

[0027] refer to Figure 1 ~ Figure 2 , a method for counting milk somatic cells based on computer vision, said method comprising the steps of:

[0028] 1. Before testing, digital microscope needs to be calibrated;

[0029] 2. Drop the dye into the milk, use the dye to stain the somatic cells, and then drop the milk into a specific glass slide;

[0030] 3. Put the slide on the detection platform and fix it;

[0031] 4. At the beginning of the detection, the upper industrial computer sends commands to the single-chip microcomputer to control the movement of the detection platform, and the slide moves accordingly. During the movement, the digital microscope collects multiple cell images and uploads them to the industrial computer. The industrial computer uses computer vision. The images are processed to derive the somatic cell count SCC.

[0032] 5. Take out the slide...

Abstract

Disclosed is a milk somatic cell counting method based on the computer vision. The method comprises the steps of dropping a coloring agent into milk, coloring somatic cells with the coloring agent, dropping the milk into a slide, and acquiring cell images by using a digital microscope, wherein the cell images are color images; preprocessing the cell images; and performing the cell image counting process: setting the somatic cell occupied pixel area range S1-S2; scanning cell binaryzation images progressively, and probing the size S of a communication area where the pixel is positioned by using a recursion method if a white pixel is found, wherein, the communication area to which the white pixel belongs is somatic cells if S1<=S<=S2, 1 is added to the somatic cell number count; otherwise, the somatic cell number count does not change; and obtaining the somatic cell number count in the cell images. According to the milk somatic cell counting method based on the computer vision, human factor influences are avoided effectively, the detection efficiency is high and the accuracy is good.

Description

technical field [0001] The invention relates to milk somatic cell measurement technology, in particular to a milk somatic cell counting method. Background technique [0002] Somatic cells in milk typically consist of macrophages, lymphocytes, polymorphonuclear neutrophils, and a small amount of mammary tissue epithelial cells. Somatic cell count (SCC) refers to the number of somatic cells contained in each milliliter of milk. [0003] SCC can reflect the degree of bacterial infection in dairy cows, and can also be used to estimate the loss of milk production in dairy cows. When the body, especially the breast, is infected or injured, body cells travel with the blood to the injured area. On the one hand, macrophages and neutrophils engulf bacteria, while lymphocytes control the immune response and produce antibodies to resist bacterial destruction and protect the body; on the other hand, it is reflected in the number of somatic cells in the expressed milk obviously increas...
