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...
