Abstract

One of the most complete techniques that can be used to digitize an artefact is to generate its photo-textured 3D model, which combines high precision metrical information with a faithful color description of the object surfaces. In this work we focus on how to obtain reliable color information by colorimetrically characterizing the color sensors of the imaging device. To this end, a novel target based characterization procedure is proposed that exploits empirical polynomial modeling for colorimetric data estimation. Experimental results are reported and discussed.
