Photovoltaic module defect detection method, device, equipment and medium

The invention discloses a photovoltaic module defect detection method and device, equipment and a medium, and the system comprises the steps: obtaining an electroluminescent image, a thermal imaging image and a visible light image of a photovoltaic module, building a sample image library based on the images, carrying out the preprocessing of the sample images in the sample image library, and obtaining a pre-processed image; marking a corresponding attribute label for each single photovoltaic module in the preprocessed sample image, extracting an image region where each single photovoltaic module is located from the preprocessed sample image so as to obtain a corresponding single photovoltaic module region image carrying the attribute label, and utilizing the single photovoltaic module region image carrying the attribute label to obtain a corresponding single photovoltaic module region image; and training a defect detection model constructed based on a preset deep learning algorithm to obtain a corresponding t
