| description | The invention relates to the field of pipeline safety maintenance, in particular to a long-distance pipeline ray image and internal detection information accurate alignment method, which specifically comprises the following steps of: firstly, extracting corresponding information of an internal detection circumferential weld serial number and a construction period weld junction serial number; then determining the welding seam type, the upstream intersection point and the downstream intersection point information in the inner detection circumferential welding seam list; constructing a deep learning instance segmentation model based on a data driving method, and reasoning an industrial negative spiral welding seam and straight welding seam area to complete upstream and downstream intersection point position deviation calculation; and finally, determining an alignment result of the internal detection data and the industrial negative film through the deviation type. According to the method provided by the inventio |
