Abstract
In this work, we present a system architecture that is especially designed for remote ultrasound testing inspections (UT). The system itself is realized using a real-time session service and a web service based on a REST API (REST: Representational State Transfer; API: application programming interface). This web service is used to store data persistently, e.g., sample geometries, raw nondestructive testing (NDT) data and derived inspection results in a shared dataspace. In the current development state, the results consist of textures mapped onto the sample geometry. This approach allows us to display the UT results directly on the real sample using mixed reality technologies. We also implemented a feature to assist the inspector remotely by making use of the availability of this digital representation. Hence, it is necessary to share additional data like the current UT-signal, temporary position marks, user and device positions, etc. between the different participants. A real-time distribution of this highly dynamic data is required to create an effective assistance environment. Therefore, a separate session service is used. The inspection data generated in this temporary session can also be transferred to the afore mentioned dataspace to be saved persistently. The system features mixed reality visualization for the inspector and optionally a virtual reality or a 3D Desktop environment for one or more remote assistants.
在这项工作中,我们提出了一种专为远程超声检测(UT)设计的系统架构。系统本身是通过实时会话服务和基于 REST API 的网络服务实现的(REST:Representational State Transfer;API:Application Programming Interface):REST:Representational State Transfer;API:Application Programming Interface)。该网络服务用于在共享数据空间中持久存储数据,如样品几何形状、原始无损检测(NDT)数据和衍生检测结果。在当前的开发阶段,检测结果由映射到样品几何图形上的纹理组成。通过这种方法,我们可以使用混合现实技术在真实样品上直接显示 UT 结果。我们还实施了一项功能,利用这一数字表示的可用性远程协助检测人员。因此,有必要在不同参与者之间共享其他数据,如当前的 UT 信号、临时位置标记、用户和设备位置等。要创建有效的辅助环境,就必须实时分发这些高度动态的数据。因此,需要使用单独的会话服务。在该临时会话中生成的检测数据也可以传输到上述数据空间中进行持久保存。该系统的特点是为检查员提供混合现实可视化,并为一个或多个远程助手提供虚拟现实或 3D 桌面环境。
