Mobile phone visible light and infrared transformer bushing image defect detection method and system

The invention provides a mobile phone visible light and infrared transformer bushing image defect detection method and system. The method comprises the following steps: S1, acquiring infrared and visible light images of a transformer bushing based on multiple cameras and/or a data transmission interface of a mobile phone; s2, the mobile phone terminal carries out fusion processing on the infrared and visible light images; and S3, the mobile phone terminal performs fault diagnosis based on the trained defect detection neural network by using the fused image to obtain a diagnosis result. According to the method, a large amount of important information in a source image is reserved, the information can be compressed, the calculation amount is reduced, real-time processing of an algorithm is facilitated, the extracted feature information is directly related to decision analysis, and a final image fusion result can reflect feature information required by analysis to the maximum extent; therefore, the target detect
