Tea cake disease monitoring and early warning system and method based on digital technology

The invention provides a tea cake disease monitoring and early warning system and method based on a digital technology, and the method comprises the steps: collecting a current target image of tea; generating difference features between the target image and a pre-stored standard image; the difference features are converted into position codes, the relevancy between the position codes and standard codes in a preset code library is calculated, whether target standard codes matched with the position codes exist in the preset code library or not is judged according to the relevancy, and if not, it is judged that the tea leaves have the tea cake disease; and obtaining positioning information of the target image, and generating early warning information including the positioning information. According to the technical scheme provided by the invention, the tea leaf monitoring efficiency can be improved. 本发明提供一种基于数字化技术的茶饼病监测预警系统和方法，其中，所述方法包括：采集茶叶当前的目标图像；生成所述目标图像与预先存储的标准图像之间的差异特征；将所述差异特征转换为位置编码，计算所述位置编码与预设编码库中各个标准编码的相
