Three-dimensional eddy current pulsed thermography and its applications
Ph. D. Thesis.The measurement and quantification of defects is a challenge for Non-DestructiveTesting and Evaluation (NDT&E). Such challenges include the precise localisation and
detection of surface and sub-surface defects, as well as the quantification of such defects. This
work first reports a three-dimensional (3D) Eddy Current Pulsed Thermography (ECPT)
system via integration with an RGB-D camera. Then, various quantitative measurements and
analyses of defects are carried out based on the 3D ECPT system.
The ECPT system at Newcastle University has been prooven to be an effective nondestructive testing (NDT) method in surface and sub-surface detection over the past few years.
Based on the different numerical or analytical models, it has achieved precise defect detection
on the rail tracks, wind turbines, carbon fibre reinforced plastic (CFRP) and so on. The ECPT
system has the advantage of fast inspection and a large lift-off range. However, it involves a
trade-off between detectable defect size and inspection area compared with other NDT
methods. In addition, there are challenges of defect detection in a complex structure. Thus, the
quantification of defects gives a higher requirement of the measurement the object geometry
information. Furthermore, the analysis of thermal diffusion requires a precise 3D model. For
this reason, a 3D ECPT system is proposed that adds each heat pixel with an exact X-Y-Z
coordinate.
In this work, first, the 3D ECPT system is built. A feature-based automatic calibration
of the infrared camera and the RGB-D camera is proposed. Second, the software platform is
built. A fast 3D visualization is completed with multi-threading technology and the Point
Cloud Library. Lastly, various studies of defect localization, quantification and thermal
tomography reconstruction are carried ou
The 1st Advanced Manufacturing Student Conference (AMSC21) Chemnitz, Germany 15–16 July 2021
The Advanced Manufacturing Student Conference (AMSC) represents an educational format designed to foster the acquisition and application of skills related to Research Methods in Engineering Sciences. Participating students are required to write and submit a conference paper and are given the opportunity to present their findings at the conference. The AMSC provides a tremendous opportunity for participants to practice critical skills associated with scientific publication. Conference Proceedings of the conference will benefit readers by providing updates on critical topics and recent progress in the advanced manufacturing engineering and technologies and, at the same time, will aid the transfer of valuable knowledge to the next generation of academics and practitioners.
