Ultrasonic inspection equipment and ultrasonic inspection method |
摘要 |
<p>A primary object of the present invention is to provide ultrasonic inspection equipment and method which facilitate alignment of display positions of three-dimensional ultrasonic inspection data and three-dimensional shape data, and which are capable of quickly discriminating between a defect echo and an inner-wall echo. A computer (102A) has a position correction function of correcting a relative display position between three-dimensional shape data and three-dimensional ultrasonic inspection data. According to the position correction function, a display position of the three-dimensional ultrasonic inspection data or that of the three-dimensional shape data is moved by a norm of a mean vector along the mean vector that is calculated from a plurality of vectors defined by a plurality of points selected in the three-dimensional ultrasonic inspection data and by a plurality of points selected in the three-dimensional shape data, the points selected in the three-dimensional shape data corresponding to the points selected in the three-dimensional ultrasonic inspection data respectively. The three-dimensional shape data and the three-dimensional ultrasonic inspection data are displayed in such a manner as to be superimposed on each other on a three-dimensional display unit (103C).</p> |
