Abstract :
The development of 3D ultrasonic technology and its extensive applications in industrial and medical fields are introduced firstly. At the following time, the principle of ultrasonic testing, the ultrasonic signal processing and the mathematical modeling are put forward. Next, a data processing method of defect positioning to reconstruct a 3D graph based on splicing technology and segmentation method is obtained. This method has already been used in an automated ultrasonic inspection system. Experimental results show good performance illustrated in the end of this paper.
