A method for analysis of yeast, comprising: capturing a microscopic image of yeast in a sample cell on a sample plate by a microscopic device and transmitting the microscopic image to a cloud server, wherein the sample plate includes a plurality of sample cells; receiving the microscopic image of the yeast in the sample cell on the sample plate by the cloud server, wherein the microscopic image includes a scaling pattern for determining a magnification, and wherein the scaling pattern is included on the sample plate, the scaling pattern including a first mark for identifying the sample plate and a second mark for identifying the sample cell; determining the magnification by the cloud server based on the scaling pattern; determining, by the cloud server, a first serial number of the sample plate based on the first mark or determining a second serial number of the sample cell based on the second mark; determining, by the cloud server, a depth of the sample cell based on the first serial number or the second serial number; and analyzing, by the cloud server, the microscopic image based on the magnification and the depth of the sample cell to obtain an analysis result, wherein the analyzing the microscopic image based on the magnification and the depth of the sample cell comprises: performing, by the cloud server, an image processing operation on the microscopic image to determine a count of the yeast in the microscopic image; obtaining the depth of the sample cell by the cloud server; and determining, by the cloud server, a total concentration of the yeast based on the depth of the sample cell, the count of the yeast, and the magnification. capturing a microscopic image of yeast in a sample cell on a sample plate by a microscopic device and transmitting the microscopic image to a cloud server, wherein the sample plate includes a plurality of sample cells; receiving the microscopic image of the yeast in the sample cell on the sample plate by the cloud server, wherein the microscopic image includes a scaling pattern for determining a magnification, and wherein the scaling pattern is included on the sample plate, the scaling pattern including a first mark for identifying the sample plate and a second mark for identifying the sample cell; determining the magnification by the cloud server based on the scaling pattern; determining, by the cloud server, a first serial number of the sample plate based on the first mark or determining a second serial number of the sample cell based on the second mark; determining, by the cloud server, a depth of the sample cell based on the first serial number or the second serial number; and analyzing, by the cloud server, the microscopic image based on the magnification and the depth of the sample cell to obtain an analysis result, wherein the analyzing the microscopic image based on the magnification and the depth of the sample cell comprises: performing, by the cloud server, an image processing operation on the microscopic image to determine a count of the yeast in the microscopic image; obtaining the depth of the sample cell by the cloud server; and determining, by the cloud server, a total concentration of the yeast based on the depth of the sample cell, the count of the yeast, and the magnification. performing, by the cloud server, an image processing operation on the microscopic image to determine a count of the yeast in the microscopic image; obtaining the depth of the sample cell by the cloud server; and determining, by the cloud server, a total concentration of the yeast based on the depth of the sample cell, the count of the yeast, and the magnification.
