Nut classification method, device and equipment based on machine vision and storage medium

The invention discloses a nut classification method and device based on machine vision, equipment and a storage medium. The method comprises the steps of obtaining a nut image of a to-be-classified nut; feature extraction is carried out on the nut image, at least one nut feature image is obtained, and the nut feature image comprises a plurality of reference pixel points; determining gradient information of each reference pixel point, and determining a target nut radius according to the gradient information; and classifying the to-be-classified nuts according to the target nut radius. The target nut radius is measured according to the nut image, the subjective influence of manual measurement can be avoided, then the to-be-classified nuts are classified according to the target nut radius, automatic detection and classification of the nuts are achieved, and compared with contact type measurement of the nuts manually through a vernier caliper in the related technology, the detection efficiency is improved.
