Noticeable color differences won't be detected by standard color video cameras. AutoVision utilizes dispersive optical devices to accurately measure reflectance spectra of parts - with greater sensitivity to color than human observers. By exploiting assembly line movement or with mechanical scanning, a map of color variations can be constructed over an extended area with accuracy. The clusters of color points show the variation in measurements. An acceptable variation limit can be set and is indicated by the sphere around a target color coordinate.
Any measurements lying outside of the sphere indicate a part out of color tolerance.
AutoVision's Color Profiler is designed with adjustable settings for production tolerances of color and recognize color variations for part grading and acceptance.
