Flaw/dent detection on forged products

Flaw/dent detection on forged products

The vision system detects dents on forged products.

The XG Series isolates contrast changes by cancelling subtle gradations in the background using a blur filter and the Real-time Shade Correction filter. By causing the normal surface contours to blend together and then removing the variations caused by uneven lighting, it is possible to isolate just the flaws and dents.


Dents were detected with a Stain Tool and a Subtraction filter, but the variations in surface contour caused the inspection to become unstable. The XG Series makes it possible to stably detect dents with the combined use of the Real-Time Shade Correction filter and the Blur filter.
