ABSTRACT:
A differential imaging colorimeter system and method which utilizes a RGB color camera to provide accurate differential colorimetry which can be employed as a portable, dedicated, offline system. The system utilizes a portable processor such as a laptop computer, a hand-held imaging head comprising a color camera, a lens, a plurality of white LED lights, a base plate defining an imaging region, housed in an opaque cover, wherein the imaging head provides a RGB video image to the portable processor; and a software program loaded on the portable processor for applying a geometric transform on an image obtained with the imaging head to match a stored reference image. The computer calculates differential colorimetry values to compare current images with a stored reference image.
