Problems solved by technology

There are the following problems in manual inspection and sampling: the work is highly repetitive, long-term test sampling will lead to a decrease in concentration, and as the number of test levels increases, the misoperation rate also increases
The laser scanning method suffers from the following problems: the measurement speed is slow due to the mechanical movement required
Lasers can cause damage to human eyes and pose a biological safety hazard

Embodiment

[0028] Such as figure 1 As shown, this embodiment provides a method for obtaining the volume of the layered liquid of the centrifuged sample. Centrifugation refers to the separation of liquids with different densities that are immiscible. The centrifuged samples are as follows: figure 2 As indicated, centrifuged samples with 3 layers of liquid were used in this example. The method for obtaining the volume of the centrifuged sample layered liquid provided in this embodiment includes the following steps:

[0029] The centrifuged test tube is grabbed by the manipulator to the image acquisition station. The image acquisition station is located in the confined space of the centrifuged sample and the image acquisition equipment. After the equipment is closed, the image acquisition station is closed inside, and the image acquisition is not affected by external light sources. environment of.

[0030] The miniature industrial camera collects the image of the centrifuged test tube, ...

Abstract

The invention discloses a centrifugal sample layered liquid volume acquisition method and relates to the technical field of image recognition. The method comprises the following steps: a mechanical gripper clamps a centrifuged test tube to move to an image acquisition station, a camera acquires a test tube picture, the position of a centrifugal test tube liquid level interface is detected and recognized by means of an image processing algorithm, and the volumes of different liquids are calculated according to the recognition results. According to the invention, automatic sampling of a centrifuged sample is realized, and heavy manual test operation is replaced.

Description

【Technical field】 [0001] The invention relates to the technical field of image recognition, in particular to a method for acquiring the volume of layered liquid of a centrifuged sample. 【Background technique】 [0002] Centrifugation is widely used in medical research and hospital testing. The separation of blood is mainly to separate liquids with different densities that are immiscible. At present, it is common to manually check the stratification phenomenon, take samples of different layers of liquid, or use laser scanning The method scans from top to bottom, and finds out the layered coordinates according to the principle that different colors of liquids absorb laser light differently, and then automatically samples. There are the following problems in manual inspection and sampling: the work is highly repetitive, and long-term test sampling will lead to a decrease in concentration. As the number of test stages increases, the rate of misoperation also increases. The laser...
