💡本章重点

• 农作物病害分类(Web端实现)

🍞一. 概述

农作物病害是国家粮食安全的一个主要威胁，是决定农作物产量和质量的主要因素。 由于传统方法缺乏必要的基础设施，并且极大程度依赖于人工经验，故诸多地区难以迅速高效地防治病害，从而影响农业的发展。因此，精确诊断农作物病害对于促进农业可持续发展至关重要。针对传统的农作物病害识别方法具有主观性并且极大程度依赖于人工经验的不足，利用卷积神经网络对农作物病害进行识别与分类。

1. 首先，利用数据增强技术扩充农作物病害原始数据集，增加数据的多样性和数量，同时可以提高训练网络的泛化能力和识别精度；

2. 然后搭建卷积神经网络对农作物图像进行病虫害的特征提取和分类，实现对农作物病害的准确识别和分类。

3. 最后通过搭建本地Web实现识别分类的可视化，可以详见视频。值得注意的是作者本人使用的是PlantVillage数据集进行训练、验证以及测试的。

Plant Village数据集共包含14中植物类别，分别为苹果、蓝莓、樱桃、玉米、葡萄、柑橘、桃、胡椒、马铃薯、树莓、大豆、南瓜、草莓和番茄。
