Abstract
Ultrasonic inspection equipment facilitates alignment of display positions of three-dimensional ultrasonic inspection data and three-dimensional shape data, and quickly discriminates 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. 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 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.
