Document Type and Number:
Japanese Patent JP2019197007
Kind Code:
A
Abstract:
To provide a determination device, a determination program, and a determination method of ultrasonic flaw detection capable of coping with reproducibility, rapidness, and accuracy of an inspection.SOLUTION: A determination device of ultrasonic flaw detection is a determination device of ultrasonic flaw detection for determining defects of a body to be inspected on the basis of a flaw detection image in which gradation of echoes acquired by ultrasonic flaw detection using a TOFD method are displayed according to amplitude, and includes an image recognition part for determining whether the defects exist by performing image recognition of the flaw detection image on the basis of a first image including an echo image of diffraction waves generated by diffraction of ultrasonic waves transmitted from a probe because of flaws of a body to be inspected and a second image including an echo image in a shape similar to an echo image of the diffraction waves included in the first image.SELECTED DRAWING: Figure 1
