Lens resolution quality detection method, device and equipment and readable storage medium

The invention provides a lens resolution quality detection method, device and equipment and a readable storage medium. The method comprises the following steps: acquiring an original image acquired by a to-be-detected lens, and extracting a region of interest from the original image; determining a segmentation threshold based on gray level distribution statistical information of the region of interest, wherein the gray level distribution statistical information comprises the number of pixel points corresponding to each gray level; dividing the gray level distribution statistical information into first gray level distribution statistical information and second gray level distribution statistical information according to the segmentation threshold; calculating a first average gray scale according to the first gray scale distribution statistical information; calculating a second average gray scale according to the second gray scale distribution statistical information; and based on the first average gray scale a
