A fresh broad bean peeling control method and system based on visual recognition
By dynamically adjusting the cutting depth and feeding frequency of the peeling blade during the peeling process of fresh broad beans using visual recognition technology, and combining this with water surface grayscale differential positioning of residual bean skins, the problems of incomplete peeling and low purity of finished products in existing technologies have been solved, achieving more efficient peeling control.

AI Technical Summary
In the current process of peeling fresh broad beans, mechanical extrusion and constant pressure hydraulic washing cause unpeeled broad beans to mix with peeled beans. The filter screen has difficulty completely separating the remaining bean skins and beans, which reduces the purity of the finished product and increases the burden of manual sorting.
A vision-based recognition method is adopted to collect image frames of fresh broad beans at the drum inlet, extract feature data, locate unpeeled areas, dynamically adjust the cutting depth of the peeling blade and the feeding frequency, and combine water surface grayscale difference to accurately locate residual bean skins, construct a multi-link feedback chain, and match the material status in real time.
It improves the peeling integrity rate and the purity of the finished product, avoids over-rolling or incomplete peeling caused by constant mechanical extrusion force, and enhances the automation control effect of the peeling process.
