Summary: | The invention discloses an automatic focusing method of a visible component analyzer. The method comprises the following steps: 1, driving a planar flow cell by a focusing motor of an automatic focusing device to enable focusing liquid to flow through the flow cell; 2, based on the flow cell through which the focusing liquid flows in the step 1, starting from an initial position, moving forwards at the same step length, shooting m images at each position, and moving n positions in total; 3, performing image segmentation on each image in the m * n images in the step 2 to obtain a standard particle image; 4, constructing a deep neural network model based on the standard particle image in the step 3; 5, training the deep neural network model in the step 4 to obtain network parameters; and 6, performing linear regression on the trained deep neural network model in the step 5, wherein the intersection point position of a regression straight line and a horizontal axis is the focus position. The method is used for s |
