Training method and detection method of light leakage detection model, equipment and storage medium

The invention provides a training method of a light leakage detection model, a detection method, equipment and a storage medium. The training method of the light leakage detection model comprises the following steps: acquiring a photovoltaic module image and a module light leakage mark of the photovoltaic module image; according to the photovoltaic module image and the module light leakage mark, determining training battery piece images in the photovoltaic module image and a battery piece light leakage mark of each training battery piece image; obtaining training sample data according to each training battery piece image and the battery piece light leakage mark of each training battery piece image; according to the training sample data, training the initial light leakage detection model to obtain a trained target light leakage detection model; the target light leakage detection model is used for carrying out light leakage detection on a battery piece included in the photovoltaic module to be detected.
