Sample shooting method and sample image analysis system based on objective lens switching

Abstract

The invention provides a sample shooting method and a sample image analysis system based on objective lens switching, the method is applied to the sample image analysis system, and the method comprises the following steps: shooting a sample in a sample smear under a first objective lens of the sample image analysis system to obtain a first sample image; switching to a second objective lens of the sample image analysis system, and shooting the sample in the sample smear under the second objective lens to obtain a second sample image; determining whether the image feature of the second sample image meets a preset condition, if so, determining that the objective lens is switched successfully, and otherwise, determining that the objective lens is switched unsuccessfully; after it is determined that the objective lenses are switched successfully, the sample in the sample smear is shot again under the second objective lens to obtain a third sample image, and the third sample image comprises at least part of image content in the first sample image. According to the scheme of the invention, automatic confirmation of objective lens switching can be realized, and the effectiveness of the shot sample image can be ensured.

Description

technical field [0001] The present application relates to the technical field of sample analysis, and more specifically relates to a sample shooting method based on objective lens switching and a sample image analysis system. Background technique [0002] In the medical field, a sample image analysis system is generally used to capture a sample image of a sample to be tested, and analyze the sample to be tested by analyzing the sample image. Among them, a digital microscope is usually used when photographing a sample. Digital microscopes generally contain multiple objective lenses with different magnifications. During use, it is often necessary to switch between objective lenses with different magnifications to photograph and observe samples, in order to take into account both efficiency and observation effect. For example, first take a sample image under a low magnification objective lens to find out the sample content to be observed, and then switch to a higher magnificat...

Problems solved by technology

[0003] In the existing sample shooting method based on objective lens switching, the lens is usually manually switched by humans, but this method is inefficient; there are also automated imaging systems that automatically complete the lens switching, but this method may have the situation of unsuccessful lens switching

In the case of unsuccessful lens switching, it will not only make it difficult for the captured sample image to achieve the purpose of observation, but also may cause damage to the observed sample on the stage and even damage the objective lens
