Lesion Chinese chestnut classification method and system based on hyperspectrum and convolutional neural network, and medium

The invention discloses a lesion Chinese chestnut classification method and system based on a hyperspectrum and a convolutional neural network, and a medium. The method comprises the steps that hyperspectral information of Chinese chestnuts with various degrees of lesions is acquired and preprocessed, and a hyperspectral data set of the Chinese chestnuts with various degrees of lesions is obtained; constructing a lesion Chinese chestnut recognition model based on an improved VGG16 convolutional neural network, and training the lesion Chinese chestnut recognition model according to the hyperspectral data sets of the lesion Chinese chestnuts of various degrees; and obtaining hyperspectral information of a to-be-detected Chinese chestnut sample, inputting the hyperspectral information into the trained lesion Chinese chestnut recognition model for detection, completing Chinese chestnut lesion recognition, and controlling a pneumatic classifier to classify lesion Chinese chestnuts according to a recognition result
