Embodiment Construction

[0084] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0085] The present invention proposes a first embodiment. like figure 1 Shown, a kind of automatic focusing method is characterized in that, described method comprises the following steps:

[0086] S01, the photographing step, controlling the imaging device to photograph the sequencing reaction region at different focus positions, and obtaining multiple sequencing images;

[0087] S02. In the step of obtaining the optimal focus position, the adaptive method is used to respectively obtain the magnetic bead recognition thresholds of the multiple sequencing images, and define the magnetic bead recognition thresholds of the multiple sequencing images that are within the preset range. The focus position corresponding to the sequencing image correspond...

Abstract

The invention relates to the field of image photographing, and provides an automatic focusing method and system. The method comprises a photographing step: controlling an imaging device carry out thephotographing of a sequencing reaction region at different focusing positions, and obtaining a plurality of sequencing images; an optimal focusing position obtaining step: respectively obtaining magnetic bead recognition threshold values of the plurality of sequencing images through an adaptive method, and determining that the focusing position corresponding to the sequencing image corresponding to the magnetic bead recognition threshold value in a preset range in the magnetic bead recognition threshold values of the plurality of sequencing images as the optimal focusing position; a focusing step: moving the imaging device to the optimal focusing position. The method and system can quickly and efficiently achieve the automatic focusing.

Description

technical field [0001] The present invention relates to the field of image capture, and more specifically, to an automatic focusing method and system. Background technique [0002] In the prior art, the shooting module is often moved with a fixed step length to take pictures of the subject, and then obtain a series of images with different focal lengths, and then obtain the image with the best definition by analyzing the sharpness values ​​of these images, and define the The position corresponding to the image with the best definition is the best focus position, and then the shooting module is moved to the best focus position for shooting. However, when the above method is applied to the field of high-throughput gene sequencing, the method for judging the clarity value of the sequencing image is relatively complicated and the efficiency is low. [0003] Therefore, there is a need for a new method and system capable of quickly realizing automatic focusing. Contents of the ...
