Interpretation method of agglutination test

Abstract

The invention discloses an agglutination test interpretation method. The method comprises the steps of firstly, performing image preprocessing to obtain a digital image of an agglutination test result, and processing brightness and contrast parameters of a picture; secondly, detecting a boundary of an agglutination test region of the picture on a computer vision platform by adopting a "Hough Transfom" extraction algorithm, and after the boundary is extracted, further performing boundary extraction according to color distribution to obtain a histogram of the extracted picture; thirdly, extracting a sample in the boundary of the agglutination test region; fourthly, extracting a sample picture according to an obtained threshold; fifthly, filtering image noises of the sample picture to obtain a sample image; sixthly, extracting agglutination reaction spots in the sample image and calculating the number of the agglutination reaction spots and an area; and finally, giving a level that the sample belongs to according to the obtained number of the agglutination reaction spots and area. According to the agglutination test interpretation method provided by the invention, by adopting imageology and computer image processing as means, the reliability of agglutination test interpretation is greatly improved and the randomness of human eye observation is reduced.

Description

technical field [0001] The invention relates to an image data processing method, in particular to a method for processing and distinguishing digital images of agglutination test results, and interpreting and giving test conclusions, so as to realize the automation of agglutination test detection. Background technique [0002] Agglutination test is a serological test in which agglutination occurs after the combination of particulate antigen and corresponding antibody. Under the action of electrolyte, the complex of antigen and antibody forms agglomerated aggregates visible to the naked eye after a certain period of time. The test can be carried out on a glass plate, called the glass plate agglutination test, and the test can be carried out on a card, called the card agglutination test, which can be used for the identification of bacteria and the qualitative detection of antibodies; it can also be carried out in a test tube, called the test tube agglutination test , mainly us...

Problems solved by technology

[0004] The automation level of agglutination test is low. When performing agglutination reaction, manual operation and interpretation are usually performed on a piece of test paper, which increases the labor and time of medical staff
