Research in Image Processing for Pipeline Crack Detection Applications

Pipelines, such as gas and utility pipeline systems and networks, are some of the most critical components of civil infrastructure. During the long-term operation of the pipeline, various types of diseases will occur. Pipeline damage may present serious environmental and economical problems. In order to solve the problem that traditional pipelines crack detection, a pipelines crack detection method based on image processing under complex background is proposed. A pipeline crack image segmentation model based on semantic segmentation is built, and cracks in high-resolution crack images are extracted by using the pipeline image segmentation model. The accuracy rate (P%), recall rate (R%), and F-score (F%) of the proposed method are recorded 89.3%,85.7%, and 80.4%, respectively. The results show that, compared with the existing algorithms, the proposed algorithm has a better detection effect and stronger generalization ability in complex pipeline scenes.
