Challenge
- Image capture under UV light
- Distinguish between noise and crack
- UV light reflection generating additional noise in image
- Thin lines of cracks generating thin indications (0.1 mm thick)
- Indefinite size and shape of the cracks
- Difference in behavior for round and flat surfaces
Solution
- Special optics with UV filters are used to get best possible image
- Image processing software solution
- Customized algorithm for pre-processing images and thin crack detection on various surfaces
- Tested for inner diameter as well as outer diameter
- Tested for flat surfaces as well
