Machine vision systems are being called upon to solve problems in inspection and control. The majority of such systems use a monochrome TV camera as the image sensor. However, such cameras cannot be applied where color plays an essential role. Color vision is particularly appropriate for dealing with colored objects or color-coded parts. The use of color permits part discrimination where gray-scale information is insufficient. A color detection system using three color filters and a monochrome TV camera is presented. Tests were made on identifying colored wires and values of color-coded resistors. The results of this first look into the use of color vision are promising.
