Low-cost Development and Testing of an on-line Measurement System Color of Industrial Application

Adrián Álvarez, Miguel A. Pérez

Abstract

This paper presents a new kind of colour sensor based on the measurement of the three channels of the CIE XYZ colour space, using optical fibres to conduct light from the illuminant to the probe and from the probe to a XYZ photo-sensor. Instead of performing conventional colour space transformation from CIE XYZ to CMY, we used a statistical procedure, avoiding the transformation dependence on illuminant. This paper shows a brief description of the colour measurement process, a prototype implementation and several experimental results.
