Abstract

Abstract:

In order to solve the problems of low efficiency， high cost and low accuracy of traditional methods of manually identifying peach tree diseases， an intelligent recognition method of peach tree diseases based on AI deep learning was proposed. Using and fine-tuning the DenseNet-169 classification model pre-trained by ImageNet， data preprocessing and model training were performed on the image of 11 common diseases of peach trees， then the web terminal was built to integrate and develop a software system for intelligent recognition of peach tree diseases. The average recognition rate of these 11 peach tree diseases was over 91% by this method. Using image recognition technology to automatically identify peach tree diseases， combined with modern science and technology such as image processing， deep learning， data mining and analysis， the intelligent diagnosis and prevention suggestions for peach tree diseases were realized. This proposed method could reduce labor costs， simplify operations， and improve recognition efficiency， so it was conducive to timely diagnosis and decision-making for prevention and treatment of diseases. Therefore， this research had important significance and application value for promoting the intelligent management of orchard disease controling， and provided support for the research and practice of image recognition methods based on deep learning with small sample sets.
