Research on Image Resolution in Ultrasonic Imaging Inspection of Welding Defect

摘要：

The resolution problem of welding seam ultrasonic imaging system is studied in this paper, a triple-stage stepwise solutions is proposed, the measured ultrasonic signal is processed by super-resolution algorithm based on wavelet transform, signal processing result shows: the method is feasible to improve image quality of ultrasound imaging equipment and enhances its ability to identify subtle defects in welding seam. Moreover, the algorithms is under further improving and enhancing in ultrasonic image..
