Objective assessment of a color or paint layer, applicable to quality control of paint applied to vehicle bodywork, based on pixel- wise evaluation of a reflected light image of an inspected surface to provide a 2D evaluation

摘要

Method for accessing a color layer in which a color layer is illuminated with a light source (6) with reflected light captured by a receiver (12). Each pixel image has five dimensions, two geometrical and three color. From the 5-D information 2-D information is extracted that is a measure for the color and brightness distribution of light reflected from a given geometrical area of the color layer.
