Claim 5:
6. The ophthalmologic intelligent consultation method of claim 1, wherein the screening out the sharp eye picture group from the eye picture set comprises:
performing graying operation on each eye picture in the eye picture set to acquire a primary eye gray picture set;
selecting each primary eye gray picture in the primary eye gray picture set as a target eye gray picture, and calculating an eye sharpness value of the target eye gray picture based on the following gray level algorithm:, Q

wherein Q refers to an eye sharpness value, I refers to a picture pixel length of the target eye gray picture, R refers to a picture pixel width of the target eye gray picture, i refers to the i-th pixel along a transverse direction in the target eye gray picture, r refers to the r-th pixel along a longitudinal direction in the target eye gray picture, F refers to a sampling frame length of the gray-level algorithm, G refers to a symbol of gray level, G(i, r) refers to a gray value of a pixel with a coordinate point (i, r) in the target eye gray picture;
determining the eye sharpness value of the target eye gray picture is greater than a preset sharpness threshold;
performing the step of selecting each primary eye gray picture in the primary eye gray picture set as a target eye gray picture in response to the eye sharpness value of the target eye gray picture is not greater than a preset sharpness threshold; and
adding the target eye gray picture to a preset sharp eye picture group in response to the eye sharpness value of the target eye gray picture is greater than a preset sharpness threshold.
