This repo contains all source code from UWPI processing to signal processing and deep learning applications.
By using non-contact laser ultrasonic scanning system, the ultrasonic signal can be acquired for further procesisng.
UWPI processing script shows how to stack signals in to 3D frame for visualization.
We can use B-SCOPE image to identify time when ultrasonic waves reach the edge or the bolted joint
The raw signal is then preprocessed by using some signal processing algorithms as follows:
The .csv files are then created and preprocessed as an input for CNN algorithms.
The other source-code is processed to upload.
