The rapid development of the logistics industry poses significant challenges to the sorting work within this sector. The fast and precise identification of moving express parcels holds immense significance for the performance of logistics sorting systems. This paper proposes a motion express parcel positioning algorithm that combines traditional vision and AI-based vision. In the traditional vision aspect, we employ a brightness-based traditional visual parcel detection algorithm. In the AI vision aspect, we introduce a Convolutional Block Attention Module (CBAM) and Focal-EIoU to enhance YOLOv5, improving the model's recall rate and robustness. Additionally, we adopt an Optimal Transport Assignment (OTA) label assignment strategy to provide a training dataset based on global optimality for the model training phase. Our experimental results demonstrate that our modified AI model surpasses traditional algorithms in both parcel recognition accuracy and inference speed. The combined approach of traditional vision and AI vision in the motion express parcel positioning algorithm proves applicable for practical logistics sorting systems.
物流行业的快速发展给该行业内的分拣工作带来了重大挑战。快速、精确地识别移动中的快递包裹对于物流分拣系统的性能具有极其重要的意义。本文提出了一种将传统视觉与基于人工智能的视觉相结合的运动快递包裹定位算法。在传统视觉方面,我们采用基于亮度的传统视觉包裹检测算法。在人工智能视觉方面,我们引入卷积块注意力模块(CBAM)和焦点-交并比(Focal-EIoU)来增强YOLOv5,提高模型的召回率和鲁棒性。此外,我们采用最优传输分配(OTA)标签分配策略,为模型训练阶段提供基于全局最优性的训练数据集。我们的实验结果表明,我们改进后的人工智能模型在包裹识别准确率和推理速度方面均超过传统算法。运动快递包裹定位算法中传统视觉与人工智能视觉相结合的方法被证明适用于实际的物流分拣系统。
