Surface inspection of an optical disc

Surface inspection of an optical disc

The vision system inspects the surface of an optical disc.

Fine Colour processing extracts data based on hues, saturation, brightness levels. This makes it possible to detect any colours that differ from a targets background colour without the having to adjust for the colour of the resin. In addition, the Ignore Intensity function can remove brightness information from the processing criteria, further stabilizing the image when lighting variations occur.


Stains were detected using the Colour Extraction function, but varying resin colours made it difficult to inspect stably. The XG Series Fine Colour Processing with stain detection makes it possible to stably extract flaws without adjusting settings, even on resin discs that vary in colour.
