Abstract
The color of each of a plurality of wires 18(1) . . . 18(8) can be determined by first placing the wires proximate to a white background (31) and then directing a pair of light beams (36,38) thereat. Each of the red, green and blue spectral components in the light reflected from each wire and in the light reflected from the surface is simultaneously sensed by a separate one of three television cameras (40,42 and 44), respectively, having a separate one of a set of red, green and blue band pass filters (52,54 and 56), respectively, thereon. The output signal of the television cameras is processed by a machine vision system (58) which first computes the ratios of the red, green and blue spectral components of the light reflected from each wire to the red, green and blue spectral components, respectively, of the light reflected from the background. Each of the red, green and blue intensity ratios computed for each wire is then compared by the machine vision system to a red, green and blue intensity ratio, respectively, established for each of a plurality of wires of known colors until a substantial match therebetween is found. When a substantial match is found, the wire of unknown color can then be identified.
