基于改进型YOLOv10算法的机器手剔除烟叶中非烟物质系统研究

A removing system for non-tobacco related materials from tobacco leaves by robotic hands based on improved YOLOv10 algorithm

  • 摘要: 为解决烟叶中非烟物质(Non-tobacco related material, NTRM)剔除时,因NTRM尺寸小、颜色与烟叶相近及复杂背景干扰导致检测效率低、剔除精度不足等问题,设计了一种基于改进型YOLOv10算法与机器手协同的NTRM剔除系统。在原有YOLOv10算法基础上引入了改进的卷积注意力模块(Convolutional block attention module, CBAM),并增设小尺寸目标检测头,以实现NTRM的快速识别与精准定位。选取生产线上出现频次较高的8类NTRM进行分析,结果表明,①改进型YOLOv10算法对NTRM检测的平均精度达94.8%,召回率达97.4%,耗时为4.2 ms,明显优于其他模型;相较于YOLOv10s原始算法,改进型YOLOv10算法的平均精度提升了1.1百分点,召回率提升了0.9百分点,耗时减少0.3 ms。②机器手剔除系统对8类NTRM的识别准确率为92.6%,剔除率为96.0%,有效提升了烟叶加工纯净度。该研究为烟草工业智能化质量控制提供了技术解决方案。

     

    Abstract: To address the issue of low detection efficiency and insufficient removing accuracy caused by the small size, similar color to tobacco leaves and complex background interference of non-tobacco related materials (NTRMs) from tobacco leaves, a NTRM removing system based on the collaboration of improved YOLOv10 algorithm and robot hands was designed. Based on the original YOLOv10 algorithm, the improved convolutional block attention module (CBAM) was introduced and small-size object detection heads were used to achieve fast recognition and precise localization of NTRMs. Eight NTRMs with high occurrence frequencies in the production line were selected for analysis. The results showed that: 1) The improved YOLOv10 algorithm achieved an average precision of 94.8%, a recall rate of 97.4% and an elapsed time of 4.2 ms for NTRMs detection, significantly outperforming other models. Compared with the original algorithm, the improved algorithm increased the average precision by 1.1 percentage points, raised the recall rate by 0.9 percentage point and reduced the elapsed time by 0.3 ms. 2) The recognition accuracy of the removing system by robotic hands for 8 NTRMs was 92.6%, with a removal rate of 96.0%, effectively improving the quality of tobacco processing. This study provides a technical solution for intelligent quality control in tobacco leaf sorting for cigarette production.
