Paper Abstract

A lot of materials used in construction industry are materials showing strong color texture, which may give the product its commercial value. We plan to perform automated appearance sorting using a tri-CCD color video camera as a measurement tool. The aim of the present work is the refinement of a calibration process allowing this tool to deliver for each pixel the same information as a spectroradiometer (CIEL*a*b* coordinates). Analysis of the acquisition tool allows characterization of the card and camera behavior (linearity of RGB gains, spatially varying and fixed pattern noises). Color calibration is performed using measurements with a spectroradiometer.
