Semantic segmentation model construction method and system for ultraviolet image of electrical equipment

The invention discloses a semantic segmentation model construction method and system for electrical equipment ultraviolet images, and the method comprises the steps: obtaining an electrical equipment ultraviolet image set, and carrying out the image marking of each electrical equipment ultraviolet image in the electrical equipment ultraviolet image set, dividing the marked ultraviolet image set of the electrical equipment into a training subset, a test subset and a verification subset; a semantic segmentation model is constructed according to the training subset, the semantic segmentation model comprises a convolution layer, an improved SPPF spatial pyramid structure, an improved CA attention mechanism, a lower sampling layer and an upper sampling layer, pruning operation is performed on the semantic segmentation model based on an improved pruning strategy, and a target semantic segmentation model is obtained; and testing and verifying the target semantic segmentation model according to the test subset and th
