种子纯度是决定农民收成与收入的关键因素,而快速精准的品种识别技术则是保障种子纯度的核心。本研究提出基于LED白光成像与YOLOv8模型融合的玉米种子无损检测方法,实验证实该方法兼具快
速、高效、高精度和无损等优势。通过搭建优化的LED白光反射成像系统,完成了4个玉米品种共12 008粒种子的图像采集与标注。对比实验显示,YOLOv8m模型的各项核心指标显著优于轻量级YOLOv8s,有效解决了形态相似品种识别精度不足的难题。该模型对4个品种的识别平均精度(AP)、召回率(Recall,
R
)和F1分数均达99.8%,mAP@0.5值高达99.4%。实时性测试中,YOLOv8m单图处理耗时68.6 ms,满足种子分选系统的低延迟需求。研究还揭示了数据集规模对模型性能的影响规律,证实YOLOv8m在不同规模数据集上均保持卓越的稳定性。本研究为种子品种识别领域提供了一种精确又实用的技术方案。
Seed purity is a critical factor determining farmers’ harvests and income, and rapid, accurate variety identification technology is the core to ensuring purity. This study proposes a non-destructive detection method for maize seeds based on the fusion of LED white-light imaging and the YOLOv8 model. Experiments confirm that this method combines the advantages of fast speed, high efficiency, high accuracy, and non-destructiveness. By constructing an optimized LED white-light reflection imaging system, we completed image acquisition and annotation for a total of 12 008 seeds from four maize varieties. Comparative experiments show that the YOLOv8m model significantly outperforms the lightweight YOLOv8s in various core metrics, effectively addressing the issue of insufficient identification accuracy for morphologically similar varieties. The model achieved an average precision(AP), recall rate(
R
), and F1 score of 99.8% for the four varieties, with an mAP@0.5 value as high as 99.4%. In real-time performance tests, the YOLOv8m model took 68.6 ms to process a single image, fully meeting the low-latency requirements of seed sorting systems. The research also reveals the impact pattern of dataset scale on model performance, confirming that YOLOv8m maintains excellent stability across datasets of different scales. The proposed method provides a precise and practical technical solution for the field of seed variety identification.
