How do you think the new GigE standards will influence the machine vision industry?

In the automotive industry, one might think of paint inspection, but car manufacturers have used automated paint systems for years without the need of automated visual inspection, Howison points out. “Today, the bulk of the effort goes into inspecting the fine visual details that make up the user interface. For example, making sure the consistency and evenness of the instrument-cluster light panel is important because the look and overall quality of that panel and the dashboard go a long way toward contributing to a driver’s impression of the car’s quality.”
Another area where color is making inroads is sports television and the reality TV programming craze, says Toshiba’s Pitre. “The broadcast market is seeking out 3CCD remote cameras for head-cam shots. They produce much better color fidelity over single-chip color cameras and the reproductions quality is essential for them. It’s critical for the color imagery to look as close to the quality of the high-end broadcast cameras as possible when they switch.”
Other applications include print inspection (quality and registration), CD and DVD labels, pharmaceutical inspection (label verification), printed circuit board (PCB) inspection, and part presence and/or detection. In addition, there are numerous quality and grading applications that involve color and texture classification for things like wood, textiles and ceramic tile.
Some applications make the choice easy, but if there is any doubt, Howison says, ask yourself these questions:
If the answer to any of the three is yes, consider color machine vision.
