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

Technical Problem

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.

Method used

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.

Benefits of technology

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.

Abstract

本发明涉及视觉识别技术领域,具体为一种基于视觉识别的鲜蚕豆脱皮控制方法及系统,包括以下步骤:采集鲜蚕豆进料图像获取HSV特征数据,检测出料口混合物生成未脱皮区域,经振动筛得筛分截留占比,经水力分离槽建立残存豆皮记录,调整刀具深度与给料频率获得动态控制方法。本发明中,通过视觉识别逐级采集鲜蚕豆进料特征、未脱皮区域、筛分截留占比及残存豆皮识别记录,构建从入口到出口的多环节反馈链路,依据筛分截留占比数据与残存豆皮识别记录动态调整破皮刀具切入深度和给料频率,使脱皮参数实时匹配,避免机械挤压恒定出力导致的过碾或脱皮不全,同时利用水面灰阶差分精准定位残余豆皮并修正运行工况,提升脱皮完整率与成品纯净度。
