SYSTEM AND METHOD FOR GENERATING A COLOUR FILTER FOR MODIFYING THE SPECTRAL RESPONSE OF A VISION SYSTEM

摘要

A system and method for generating a colour filter for modifying the spectral response of a vision system are disclosed. The method includes receiving an RGB spectral response of the vision system for a colour target under predetermined illumination and executing, by a processor of a computer system, computer program instructions configured to apply the RGB spectral response to a bilinear optimisation problem that simultaneously determines: i) a colour correction matrix to transform the RGB spectral response to XYZ colour space; and, ii) parameters of the colour filter. The method further executes computer program instructions configured solving the bilinear optimisation problem; and then provides the parameters or causes a colour filter to be formed using the parameters.
