In recent years, the application of deep learning technology in the field of food engineering has developed rapidly. As an essential food raw material and processing target, the number of kernels per maize plant is a critical indicator for assessing crop growth and predicting yield. To address the challenges of frequent target ID switching, high falling speed, and the limited accuracy of traditional methods in practical production scenarios for maize kernel falling count, this study designs and implements a real-time kernel falling counting system based on a Convolutional Neural Network (CNN). The system captures dynamic video streams of kernel falling using a high-speed camera and innovatively integrates the YOLOv8 object detection framework with the ByteTrack multi-object tracking algorithm to establish an efficient and accurate kernel trajectory tracking and counting model. Experimental results demonstrate that the system achieves a tracking and counting accuracy of up to 99% under complex falling conditions, effectively overcoming counting errors caused by high-speed motion and object occlusion, and significantly enhancing robustness. This system combines high intelligence with precision, providing reliable technical support for automated quality monitoring and yield estimation in food processing production lines, and holds substantial application value and prospects for widespread adoption.
近年来,深度学习技术在食品工程领域的应用发展迅速。作为一种重要的食品原料和加工对象,每株玉米的籽粒数是评估作物生长和预测产量的关键指标。为解决实际生产场景中玉米籽粒掉落计数面临的频繁目标ID切换、高掉落速度以及传统方法精度有限等挑战,本研究设计并实现了一种基于卷积神经网络(CNN)的实时籽粒掉落计数系统。该系统利用高速摄像机捕捉籽粒掉落的动态视频流,并创新性地将YOLOv8目标检测框架与ByteTrack多目标跟踪算法相结合,建立了高效准确的籽粒轨迹跟踪和计数模型。实验结果表明,该系统在复杂掉落条件下实现了高达99%的跟踪和计数准确率,有效克服了高速运动和物体遮挡引起的计数误差,显著提高了鲁棒性。该系统兼具高智能与高精度,为食品加工生产线的自动化质量监测和产量估计提供了可靠的技术支持,具有巨大的应用价值和广泛应用前景。
