摘要(Abstract):

为了满足工业无损检测中人们利用超声点云数据进行三维重建的需求,提出一种UML与组件技术相结合的用于超声三维可视化无损检测系统的建模方法.分析系统需求,并利用UML和组件技术相结合的建模方法,构建出超声三维可视化无损检测系统模型,包括系统的架构、需求、用例、静态类、活动、时序和组件部署模型,开发出超声三维可视化无损检测软件系统原型,并经过实例验证了建模方法的有效性.系统开发实践证明:基于UML和组件技术的超声三维可视化系统结构设计合理,复用性、维护性和可拓展性强,为研究超声点云的三维重建算法和将其用于工业无损检测的目标提供了实验依据和实验平台.
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.
