Detection method for detecting sample, and apparatus

Abstract

The present invention provides a method and an apparatus for detecting a sample containing at least an object requiring detection. The method comprises: adopting a detection having light sources with different positions to sequentially irradiate the sample with the light sources with different positions to obtain a plurality of projections produced on the one projection surface of the object requiring detection under irradiation of the light sources with different positions; and comparing the plurality of the projections of each object requiring detection and a plurality of projections of a reference object with the known type so as to determine the type of the object requiring detection. According to the present invention, the existing large and complex pattern recognition software is not required, and the error caused by different proficiency of operators is avoided.

Description

technical field [0001] The invention relates to a detection method and a device, in particular to a method and a device for detecting blood, urine and solutions containing components with fixed shapes, which can be used for fast and reliable component detection. Background technique [0002] A complete blood count (CBC, also known as a full blood count, FBC) also known as a full blood exam (FBE) or a full blood panel (full blood panel) is a test that doctors and other medical practitioners often A required test that gives information about a patient's blood cells. The tester completes the required tests and provides the CBC results to the doctor or other medical practitioner. [0003] Cells in blood are roughly divided into three categories: white blood cells (WBC, leukocytes), red blood cells (RBC, erythrocytes) and platelets (PLT, thrombocyte). Excessively high or low blood cell counts can indicate the existence of various diseases, and blood cell counts can reflect the ...

For example, US2012 / 0098950A1 describes an image-based detection device and detection method. Multiple light sources are used to irradiate blood samples to obtain multiple low-resolution images, and then according to the position between multiple light sources The relationship is to combine multiple low-resolution images into a high-resolution image to reflect the topographic image of the cells to be tested, and then the operator can judge and classify the cell types based on the high-resolution images of the cells to be tested, but the skilled operators Differences in degree may cause errors in the results, and the type of cells can also be judged based on high-resolution images through complex and huge image recognition software or expensive blood cell data acquisition systems, although differences in operator proficiency can be avoided The result error caused by it, but the cost is higher
