Abstract
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.
Highlights
Digital representations of non-destructive testing and evaluation (NDT/NDE) results are commonly displayed as two-dimensional images disregarding the actual threedimensional surface structure of the examined objects
The presented demonstrator shows a lot of possible ways of how to change and improve nondestructive testing (NDT) processes— from the inspector’s point of view, and in regard to the way the data will be processed and used
The potential benefits can be separated in two main areas: The first area deals with the inspector and the execution of the testing itself
Summary
Digital representations of non-destructive testing and evaluation (NDT/NDE) results are commonly displayed as two-dimensional images disregarding the actual threedimensional surface structure of the examined objects. Nondestructive ultrasonic scans (UT) covering a curved area suffer from this flattening effect. In order to correctly reallocate collected data to its measurement point, the inspector is burdened with an additional cognitive load. The second disadvantage is the lack of a permanent relation to the examined area on the aircraft structure, which may be important for future analyses and damage comparison. Because of the missing link to the real structure respectively its digital representation, even today temporary marks are drawn onto large objects like the surface of aircraft structures to record and discuss the effects of damages.
