摘要: 快速有效检测农作物病理对于农业具有重大的意义,不仅能提高自动化识别病理效率,还可以提高农作物产量。以土豆、番茄等农作物作为病理研究对象,提出一种基于卷积神经网络的农作物病理分类模型MFCPNet。首先构建深度卷积神经网络模型,分别通过卷积层、激活层、池化层全连接层进行组建,然后将提取到的图像病理特征进行多特征融合,从而有效增强农作物病理的特征丰富度。同时对原数据集进行数据增强从而消除样本分布不均的问题。结果表明,所提出农作物病理分类模型的各项标准均优于AlexNet、VGG16、VGG19模型,达到了94.92%的准确率,同时省去人工搭建复杂的特征工程,对推动农业自动化具有一定的价值。

Abstract: The rapid and effective detection of crop pathology is of great significance to agriculture. It can not only improve the efficiency of automated pathology recognition, but also increase crop yields. This paper takes potato, tomato and other crops as the pathological research object, and proposes a crop pathological classification model based on convolutional neural network MFCPNet. First, build a deep convolutional neural network model, which is constructed through a convolutional layer, an activation layer, and a fully connected layer of a pooling layer. Then, the extracted image pathological features are fused with multiple features to effectively enhance the feature richness of crop pathology.At the same time, the original data set is enhanced to eliminate the problem of uneven sample distribution. The results show that the standards of the proposed crop pathology classification model are better than the AlexNet, VGG16 and VGG19 models, reaching an accuracy of 94.92%. At the same time, it eliminates the need for manual construction of complex feature projects, which has a certain value in promoting agricultural automation.

Key words: crop pathology classification, convolutional neural network, feature fusion
