Power transmission line image defogging method, system and equipment based on deep learning

The invention discloses a power transmission line image defogging method, system and device based on deep learning, and belongs to the technical field of power system monitoring. The method comprises the following steps: determining a rough transmissivity graph of a foggy image by adopting a dark pass prior method; inputting the foggy image and the rough transmissivity map into a target neural network model to obtain an accurate transmissivity map output by the target neural network model; the target neural network model is obtained by training an MSCNN network model into which a residual module is introduced; and carrying out defogging operation on the foggy image by using the accurate transmissivity graph. According to the embodiment of the invention, the MSCNN network model introducing the residual module is adopted to obtain the accurate transmissivity graph, the characteristic that the deep learning model has higher generalization ability is fully utilized, and the method can adapt to the transmission li
