Automatic Identification and Location of Tunnel Lining Cracks

The lining crack is common for the tunnel in stage of operation, which has seriously influenced service life and safety engineering. It a new trend to use computer vision detect cracks over past few years China foreign countries. By image processing technology intelligent algorithm, hominine visual perception system understands, analyzes, determines input information, thus recognizing detecting specific objectives. However, effect recognition now cannot satisfy demands practical SSD algorithm been used when analyzing features surface image, while comparison analysis made from results, error rate, running time. results indicate that can accurately rapidly mark position crack. information obtained subsequently imported into team independently developed software GeoSMA-3D, useful determining grade.
