Comparison of Spectral Colorimetric Measurements vs. Color Pictures in Dermatology

We studied scars and wounds depths and surfaces thanks to our interferometric fringes projector 3D scanner1, 2. Color information of a wound indicates its deterioration level. That’s why the visual color restitution, as realistic as possible, is a highly important parameter. Firstly our acquired 3D pictures were color mapped with an image recorded by a RGB camera. The results were not efficient enough. In order to improve our technique and provide more precise information, we add a spectral characterization to the set-up. Before adding the spectral information and a realistic color mapping to the 3D measurements, we evaluate the performances of colorimetric measurements. The tests have been made on mice with scars on their back.
