[0002] Pipelines are an important part of many industrial production systems, and their operating conditions are directly related to the safety of the entire production equipment and facilities. If there are defects in the pipelines, such as cracks, corrosion perforations, etc., it may lead to major accidents. Among many detection equipment, DR detection can clearly show cracks on the inner wall of the pipeline at the millimeter level or even smaller;
