QUANTITATIVE IMAGING METHOD OF STRUCTURE DEFECT DIAGNOSIS SIGNAL USING GUIDED ULTRASONIC WAVE

摘要

The present invention relates to a quantitative tomography imaging method of a structure defect diagnosis signal using a guided ultrasonic wave to visually display structure defect diagnosis using a guided ultrasonic wave, which comprises: a first step of setting an inspection range of an object to be inspected to arrange a plurality of probes in an upper end of the object to be inspected; a second step of collecting a detection signal of the object to be inspected through the probes; a third step of comparing the detection signal of the object to be inspected and a predetermined reference signal; a fourth step of extracting a defect signal by applying a tomography algorithm to the comparison resu and a fifth step of quantitatively imaging a defect by applying a variable shape function to the defect signal.;COPYRIGHT KIPO 2017
