Counting wheat heads is a time-consuming process in agricultural production, which is currently primarily carried out by humans. Manually identifying wheat heads and statistically analyzing the findings has a rigorous requirement for the workforce and is prone to error. With the advancement of machine vision technology, computer vision detection algorithms have made wheat head detection and counting feasible. To accomplish this traditional labor-intensive task and tackle various tricky matters in wheat images, a high-precision wheat head detection model with strong generalizability was presented based on a one-stage network structure. The model's structure was referred to as that of the YOLO network; meanwhile, several modules were added and adjusted in the backbone network. The one-stage backbone network received an attention module and a feature fusion module, and the Loss function was improved. When compared to various other mainstream object detection networks, our model outperforms them, with a of 0.688. In addition, an iOS-based intelligent wheat head counting mobile app was created, which could calculate the number of wheat heads in images shot in an agricultural environment in less than a second.
在农业生产中,数麦穗是一个耗时的过程,目前主要由人工完成。人工识别麦穗并对结果进行统计分析对劳动力有严格要求,而且容易出错。随着机器视觉技术的发展,计算机视觉检测算法使麦穗检测和计数成为可能。为了完成这项传统的劳动密集型任务并解决小麦图像中的各种棘手问题,基于单阶段网络结构提出了一种具有强通用性的高精度麦穗检测模型。该模型的结构参考了YOLO网络;同时,在主干网络中添加并调整了几个模块。单阶段主干网络接收了一个注意力模块和一个特征融合模块,并对损失函数进行了改进。与其他各种主流目标检测网络相比,我们的模型表现更优,平均精度均值为0.688。此外,还创建了一个基于iOS的智能麦穗计数移动应用程序,它可以在不到一秒的时间内计算出在农业环境中拍摄的图像中的麦穗数量。
