Abstract
The invention provides a weld joint internal defect intelligent detection device and method and a medium, X-rays emitted by an X-ray tube irradiate a weld joint to obtain a digital image containing weld joint internal quality information on an imaging plate, optimal imaging is realized through an optical path simulation and control unit, and after the generated image is automatically uploaded to acloud platform server, a digital image processing technology and a deep learning neural network algorithm are adopted to carry out intelligent preprocessing on the image, whether defects exist or notis judged, defect positioning, defect type identification and defect rating are carried out, and detection of image characterization quality is achieved. According to the invention, the precise control of the complex structure weld joint detection process is realized in the detection process; in the image evaluation process, a manual film evaluation process is replaced by intelligent defect identification, so that the manual detection duration is effectively shortened, personal errors are avoided on the premise of ensuring the defect identification accuracy, and the welding seam quality detection working efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of intelligent detection, in particular to an intelligent detection device, method and medium for internal defects of welds. Background technique [0002] At present, in the industrial field, the detection of internal defects of welds is an important part of the quality inspection of the production process. Digital radiography technology is usually used to take pictures of the internal information of welds, and then experienced workers interpret the internal defects of welds based on the films. However, the defect evaluation of digital radiographic images requires qualified skilled workers, and it takes a lot of time and money to train skilled workers. Moreover, a large amount of review work can easily lead to fatigue of skilled workers, which can easily lead to misjudgments and missed judgments. Wait for human error. At the same time, with the development of productivity and the increase of output, higher ...
