Electric power system oil leakage detection method and device, model training method and device and computer equipment

The invention relates to an electric power system oil leakage detection method and device, a model training method and device, computer equipment, a storage medium and a computer program product. The method comprises the following steps: acquiring a polarization image set and a visible light image set of an oil leakage area; labeling the polarization image set and the visible light image set to obtain a labeled image set; converting the polarization image set to obtain a polarization degree image set and a polarization angle image set; inputting the polarization degree image set, the polarization angle image set and the visible light image set into a coding-decoding model to obtain a fused polarization image set; and inputting the fused polarization image set and the labeled image set into a target detection model to generate a power system oil leakage detection model. By adopting the method, a model with relatively good detection performance can be trained, so that efficient detection of the oil leakage area
