Problems solved by technology

[0006] The chyle detection method based on machine vision and image analysis is more and more widely used, but some of the current detection methods based on image analysis are only limited to image gray Calculation and analysis of degree value (such as CN201210052269-liquid turbidity test method and device based on image grayscale detection, can lead to the existence of background interference and cause deviation in detection results
Therefore, removing background interference plays an important role in improving the accuracy of detection results, but there is currently a lack of reliable solutions

Embodiment 2

[0064] Conventional color image grayscale processing method is used to detect plasma chyle level, and the specific steps include:

[0065] 1. Under 1 white light source, the plasma image to be tested is collected by the CCD camera, such as image 3 shown;

[0066] 2. Perform grayscale processing on the image, such as Figure 4 ;

[0067] 3. The target pattern is automatically selected, and the selected area just includes the pattern printed on the back of the cuvette for colorimetric judgment, such as Figure 5 ;

[0068] 4. Perform grayscale processing on the target pattern area; then perform threshold method binarization processing to obtain the grayscale value of the target pattern, such as Image 6 Then calculate the ratio between the gray value of the target pattern and the gray value of normal plasma, thereby judging the degree of plasma chyle, the calculation results are as follows in Table 1 and Figure 7 Shown:

Embodiment 3

[0077] Using the system and method provided in Example 1 of the present invention to detect the degree of plasma chyle, the specific steps include:

[0078] 1) Obtain the color image of the plasma to be tested under a white light source, such as Figure 9 Shown; Calculate the RGB value of the plasma background color to be tested and feed back;

[0079] 2) Calculate the RGB value of the background color of the plasma to be tested, and feedback control the multi-band light source to emit light with the same or similar color as the background color of the plasma, so as to obtain the background color of the plasma to be tested in which the background color of the plasma is white under the light source Wavelength images such as Figure 10 shown;

[0080] 3) Select the target pattern area, and perform grayscale processing on the target pattern area; then perform threshold method binarization processing to obtain the grayscale value of the target pattern, such as Figure 11 Then c...

Abstract

The invention discloses a plasma chyle degree detection method and system. The method comprises the following steps: 1) adding to-be-detected plasma into a transparent cuvette, and obtaining a color image of the to-be-detected plasma under a white light source; 2) collecting a ground color wavelength image of the to-be-detected plasma again under a multi-band light source; and 3) performing imageprocessing on the ground color wavelength image of the to-be-detected plasma to obtain a ratio of the gray value of a target pattern area to the gray value of normal blood plasma, thereby qualitatively judging the chyle degree of the to-be-detected plasma. After white LED light source imaging, the RGB value of the plasma color is obtained, then the multi-band LED light source is controlled to emitlight with the color similar to that of the background, and imaging is carried out, so that large gray difference can be generated between target features and the background, analysis and eliminationof background interference are better facilitated, and the accuracy of a detection result is improved.

Description

technical field [0001] The invention relates to the field of detection of plasma chyle, in particular to a method and system for detecting the degree of plasma chyle. Background technique [0002] In recent years, with the continuous improvement of living standards, the proportion of chyle blood in the blood of voluntary blood donors has gradually increased. After the human body ingests a large amount of fat, it is hydrolyzed into fatty acids and monoglycerides by the esterase secreted by the pancreas in the intestine. After being absorbed by the intestinal mucosa, it becomes tiny chylomicrons and enters the blood circulation through the lymphatic vessels. Chylemia is also common in patients with hyperlipidemia. one of the comorbidities. [0003] The serum of patients with chyleemia carries a large amount of low-density lipoprotein (LDL), very low-density lipoprotein (VLDL) and chylomicrons, which mainly use triglyceride (TG) and cholesterol (CHO) as raw materials. In part...
