Problems solved by technology

[0003] At present, most domestic hospitals use manual operations such as the slide method for blood type interpretation. The manual operation is slow, time-consuming and laborious, consumes a lot of reagents, the results are not easy to observe, and errors are prone to accidents. Manual operations are generally only used for positive determination projects.

Embodiment 1

[0035] Such as figure 1 As shown, a blood type identification method based on a blood type card comprises the following steps:

[0036] S1: Prepare the blood type card of the blood sample to be tested by using the microcolumn gel method. The blood type card includes eight microcolumn tubes, and each microcolumn tube has a specific reagent gel to react with red blood cells. The way to collect the reaction result images in the eight microcolumn tubes on the blood type card is as follows: figure 2 as shown (the corresponding gel column will appear in each microcolumn tube as shown in 3);

[0037] S2: Acquiring the horizontal boundaries of the reaction result images in the eight microcolumn tubes collected on the blood type card, binarizing the obtained horizontal boundaries, and obtaining the longitudinal area where the positioning features on each microcolumn tube are located;

[0038] S3: Segment the area occupied by the positioning feature from the obtained longitudinal are...

Abstract

The invention provides a blood type distinguishing method based on a blood type card. The blood type distinguishing method based on the blood type card comprises the following steps: according to positioning characteristics of micro column tubes in the blood type card, calculating to obtain a coordinate position where column gel in each micro column tube in the blood type card is located, partitioning a gel column graph of each tube, and carrying out gray value statistics on all regions in each column body and comparing, so that negative and positive characteristic of reaction in each column body and reaction intensity characteristic can be obtained. By combining the negative and positive characteristics of each tube corresponding to a sample and reaction intensity reference values, a final blood type result of the sample can be obtained, manual operation is reduced, and efficiency can be improved.

Description

technical field [0001] The invention relates to the field of medical image processing, and more specifically, to a blood type discrimination method based on a blood type card. Background technique [0002] The blood type identification method of the blood type card is based on the automatic identification technology of the characteristic image formed after the reaction between the reagent and the sample red blood cell in the blood type card. This technology can obtain the blood type of the sample and the information of the blood type reaction intensity. It is of great significance for clinical blood tests, matching blood types, etc. [0003] At present, most domestic hospitals use manual operations such as the slide method for blood type interpretation. Manual operations are slow, time-consuming and laborious, consume a lot of reagents, and the results are not easy to observe, prone to errors and accidents, and manual operations are generally only used for positive determina...
