1. A sample image photographing method, comprising:
transporting a test sample carrier by means of a sample carrier transport device to an imaging device comprising a camera and an objective lens;
obtaining horizontal position coordinates of at least three reference points in a sample area of the test sample carrier by means of a control device;
moving the test sample carrier horizontally relative to the imaging device by means of a horizontal drive component of a driving device to allow the at least three reference points to separately stop within a field of view of the imaging device, so that the imaging device separately focuses on the at least three reference points;
determining a focusing surface representation function of the test sample carrier by means of the control device according to the horizontal position coordinates and focusing parameters of the at least three reference points, the focusing surface representation function representing a relationship between horizontal position coordinates and focusing parameter of each point to be photographed in the sample area of the test sample carrier;
continuously moving the test sample carrier horizontally relative to the imaging device by means of the horizontal drive component of the driving device;
causing each point to be photographed in the sample area of the test sample carrier to satisfy the focusing surface representation function when said point is within the field of view of the imaging device by means of a vertical drive component of the driving device and/or the imaging device during the continuous horizontal movement; and
continuously photographing each point to be photographed in the sample area of the test sample carrier by means of the imaging device during the continuous horizontal movement to obtain a sample image.
