Complex scene power equipment defect identification method and device and computer equipment

The invention relates to a complex scene power equipment defect identification method and device and computer equipment. The method comprises the following steps: inputting a power grid inspection image into a scene feature extraction model to obtain scene features of the power grid inspection image; according to the scene features, screening a defect identification trunk model map to obtain a target trunk model corresponding to the power grid inspection image; inputting the scene features and the power grid inspection image into the target trunk model to obtain trunk features of the power grid inspection image; inputting the trunk feature into a defect identification neck model to obtain a target reinforcement feature of the power grid inspection image; and inputting the target enhanced feature into a defect identification head model to obtain a defect identification result of the power grid inspection image. By adopting the method, the defect identification accuracy of the power equipment in a complex scene
