What is the difference between "domestic AOI" and "imported German AOI"?

At present, many domestic brands of AOI and machines made in Germany have adopted vector analysis technology (namely RGB three primary colors), and this technology patent belongs to Omron of Japan.

The models after telex 7500 all adopt tricolor technology, and the previous models all adopt black and white light gray scale technology.

At present, the comparison of pictures used before the earliest AOI Shenzhou Vision in China is also the comparison of three primary colors and pictures.

Three primary colors are the mainstream AOI detection algorithm at present, and most domestic machines are using this technology: Weijintou, Cologne, Ming Rui.
