In order to meet the needs of 3D reconstruction using ultrasonic point cloud data in industrial NDT,a modeling method for ultrasonic 3D visualization NDT system based on combination of UML and component technology is proposed in this paper.By analyzing the system requirements and using the modeling method of the combination of UML and component technology,the ultrasonic 3D visual NDT system model is then established.This system model includes the model of system architecture,requirement,use case,static class,system sequence,activity and component deployment.A prototype of the ultrasonic 3D visual NDT software system is therefore developed,and the effectiveness of the modeling method is verified by examples.The development practice of the system model proves that the ultrasonic 3D visualization system based on the combination of UML and component technology has a lot of advantages of reasonable structure design,strong reusability,maintainability and expandability,which does provide an experimental basis and experimental platform for developing 3D reconstruction algorithm of ultrasonic point cloud and for using 3D visualization system in industrial NDT.
