Project description
Non-destructive testing and evaluation (NDT&E) systems using open-ended waveguide (OEW) face critical challenges.
At the sensing stage, data acquisition is time-consuming by raster scan. On-line detection is difficult. The sensing stage also disregards demand for the feature extraction process. This leads to an excessive amount of data and processing overhead for feature extraction.
At the feature extraction stage, efficient and robust defect region segmentation is challenging for a complex image background. Compressed sensing (CS) demonstrates an impressive data compression ability using sparse models.
We will specify the information necessary to operate and compete. We will also investigate how this information is sensed and applied.
We are developing integrated sensing-processing CS models to address the drawbacks in OEW NDT systems. We will carry out case studies in low-energy impact damage detection for carbon fibre reinforced plastics (CFRP).
