Infrared vision-assisted pipeline outer wall crack identification and early warning method and system

The invention discloses an infrared vision-assisted pipeline outer wall crack identification early warning method and system, and the method comprises the steps: building a pipeline crack infrared monitoring system through infrared monitoring equipment, carrying out the monitoring of the outer wall of a sample pipeline, obtaining infrared image sample data, carrying out the deep feature extraction through a feature fusion pyramid network, and carrying out the recognition and early warning of a pipeline outer wall crack. The features are further optimized and fused through bottom-up and top-down information transmission paths by using a multi-level feature optimization network, the bottom-up path enhances the capture of local details, and the top-down path transmits higher-level semantic information; and pipeline crack identification data is obtained by sharing the double-label detection head, so that the pipeline crack can be rapidly and accurately identified. According to the invention, efficient and accurat
