“…In Figure 1, O represents the central origin, A 1 (x 1 , y 1 ), B 1 (x 1 , y 1 ), and C 1 (x 1 , y 1 ) represent the origin position of the change interval of the image feature threshold, while D 1 , D 2 , and D 3 represent intersections. According to the digital twin image texture feature model shown in Figure 1, data are extracted through threshold judgment analysis [16,17]. We realize the functions of digital twin control, equipment monitoring, abnormal alarm, and life prediction, and determine the image texture feature model.…”

The purpose of image smoothing is to improve the visual effect of the image and improve the clarity of the image, so as to make the image more conducive to computer processing and various feature analysis. Because the current technology fails to smooth the preprocessed image, it leads to the extraction of image texture features. The anti-interference performance is weak. For this reason, an image texture feature extraction technology based on the digital twin is proposed. Similarity analysis is carried out through the internal structure of the image, and the image is smoothed by the semisupervised learning method. On the basis of optimizing the denoised image through digital twinning, detect target feature points in the original image, then remove the abnormal and split feature points, assign the direction of image texture feature points, and build a fuzzy back propagation neural network model. Image texture feature extraction technology is implemented. The experimental results show that, compared with the traditional method, the proposed technique has a strong identification of original image features, and has a strong consistency with original data, and has a strong ability to resist the influence of abnormal data, noise, or redundant feature points.

“…The fourth revolution integrates the digital tools (from third) and physical methods of interrogating materials (from second) in a closed-loop manner reducing human intervention and enhancing inspection performance. Within the context of the physical-digital-physical loop of NDE 4.0 [19,20,22]; digital technologies and physical methods may continue to evolve independently, interdependently, or concurrently. The real value is in the concurrent design of an inspection system through the application of Digital Twins and Digital Threads [22,23].…”

Regardless of its local name, fahrplans, hoja de ruta or feuille de route, Roadmaps through time have been instru-mental for guiding and thrusting sociocultural, economic, technological and even political changes around the world. When recently a diverse community of NDE 4.0 stakeholders, dispersed over continents and industries, began to interact and bring together a series of common challenges and collaboration initiatives, two questions materialized from those early interactions: “Does the integration of a global NDE 4.0 roadmap is feasible?” and “Does creating such global roadmap truly matters?”. This presentation, and its associated article, aims to provide an answer to both questions by succinctly portraying: 1) The journey to a create a Global NDE 4.0 Roadmap, understanding it as a milestone initiative, through a process that comprised from the mapping of the NDE 4.0 national ecosystems to the definition of a strategic path to reinforcing a Global NDE 4.0 Ecosystem. 2) The pathway for its sustainability and evolution through the integration of specific reinforcing mechanisms and processes since its early design. By merging strategy and innovation, our purpose is also to contribute with the global NDE community by provid-ing valuable practical insights related with: 1) Using and adapting the global NDE 4.0 roadmap to specific needs in order to create specialized roadmaps by industry or geographic region, that are both feasible and relevant. 2) Presenting a strategic sustainability perspective towards the future that may serve as guidance and inspira-tion to keep those specialized roadmaps relevant and useful 3) Integrating the human perspective into NDE 4.0 through professional and personal development paths and certifications, and finally 4) Outlining an agenda of future research aligned with the purpose of NDE 4.0 of contributing to creating a safer and more sustainable word.

“…It is a multidisciplinary approach aiming to implement technologies of Industry 4.0 as well as new process structures to create and improve value chains. To achieve this goal underlaying concepts like digital twins are being used [5]. A digital twin is a virtual representation of a real-world object.…”

3D-Visualization of Ultrasonic NDT Data Using Mixed Reality

et al. 2022

In this paper we present an approach where ultrasonic testing data (UT) is linked with its spatial coordinates and direction vector to the examined specimen. Doing so, the processed nondestructive testing (NDT) results can be visualized directly on the sample in real-time using augmented or virtual reality. To enable the link between NDT data and physical object, a 3D-tracking system is used. Spatial coordinates and NDT sensor data are stored together. For visualization, texture mapping was applied on a 3D model. The testing process consists of data recording, processing and visualization. All three steps are performed in real-time. The data is recorded by an UT-USB interface, processed on a PC workstation and displayed using a Mixed-Reality-system (MR). Our system allows real-time 3D visualization of ultrasonic NDT data, which is directly drawn into the virtual representation. Therefore, the possibility arises to assist the operator during the manual testing process. This new approach results in a much more intuitive testing process and a data set optimally prepared to be saved in a digital twin environment. The size of the samples is not limited to a laboratory scale, but also works for larger objects, e.g. a helicopter fuselage. Our approach is inspired by concepts of NDE 4.0 to create a new kind of smart inspection systems.
