Problems solved by technology

However, there are still some deficiencies in this algorithm fusion method. For example, this method requires that when multiple focus images are obtained, the object must not be displaced, otherwise the algorithm fusion cannot avoid the phenomenon of "smear"; in addition, this method needs to traverse many All the pixels of an image will seriously slow down the calculation speed of the fusion algorithm when processing high-definition images, occupying too many system resources, thereby reducing the user's device experience.

Embodiment 1

[0028] Please refer to figure 1 , a medical testing device is disclosed in this implementation, which includes a microscope 11, a camera 12, and a detector 13, which will be described separately below.

[0029] The microscope 11 has an objective stage 111, an objective lens 112 and an eyepiece 113, wherein the objective stage 111 is used to carry the glass slide with the sample dropped, the objective lens 112 is used to focus on the glass slide with the sample dropped with different focal lengths, and the eyepiece 113 is used for The image reflected into the objective lens 112 is visually observed on the glass slide. In addition, the objective lens 112 has an automatic zooming capability, and zooming is realized by switching different lenses or fine-tuning the focal length.

[0030] The camera 12 is arranged at the eyepiece 113 , and is used to take pictures of the glass slide through the eyepiece 113 of the microscope 11 . The type of camera and camera parameters can be sel...

Embodiment 2

[0038] On the basis of the medical detection device disclosed in Embodiment 1, this embodiment discloses an image recognition method based on multi-focal distances, which is mainly used in figure 1 On the detector 13 shown in the figure, so as to realize the corresponding function.

[0039] Please refer to figure 2 , in this embodiment, the image recognition method for protection includes steps S210-S230, which are described below respectively.

[0040] Step S210, acquiring a plurality of sample images with different focal lengths, wherein each sample image includes one or more detection targets, where the detection targets can be the imaging state of cells and / or microorganisms, then each detection target corresponds to a single cell or single microorganism.

[0041] In this embodiment, in order to make the sample in a better distribution state on the glass slide and capture a better sample image, the detector 13 can control the camera 12 to take pictures after the sample ...

Embodiment 3

[0077] Please refer to Figure 7 , this embodiment discloses a medical detection device, the medical detection device 3 may include a memory 31 and a processor 32 .

Abstract

The invention discloses an image recognition method and device based on multiple focal lengths and a storage medium. The image recognition method comprises the steps of acquiring multiple sample images with different focal lengths; respectively carrying out target identification on each sample image to obtain identification information of each detection target in each sample image; and performingduplicate removal processing according to the identification information of each detection target in each sample image, and storing the detection targets after duplicate removal into a preset multi-focus image target set. According to the technical scheme, all detection targets can be effectively recognized without multi-focus reconstruction of the sample images, so that the accuracy of image recognition can be improved, the image processing speed can be increased, the time required for recognition can be shortened, and the practical performance of a medical detection device can be improved.

Description

technical field [0001] The invention relates to the technical field of medical detection, in particular to a multi-focal-based and device and a storage medium. Background technique [0002] In existing medical detection devices, it is often necessary to capture images of samples after staining or color development, and the quality of the captured images plays a vital role in subsequent sample analysis. When the thickness of the object to be photographed is greater than the depth of field, there will be a situation in which part of the captured image is in the focal plane and part is in a defocused state, that is, close objects are clearly captured while distant objects are blurred, and at this time it cannot be well captured. If the information of the out-of-focus object is obtained, the accuracy of image recognition will be seriously affected when a single focus image is used for recognition. [0003] At present, the technical means to solve the out-of-focus problem is to ...
