Multispectral camera set-ups are often expensive, they require special cameras with more resolution, due to the increase of spectral bands to be captured. Here we show this procedure is equivalent to solve an equations system, derived from illuminating with several light conditions a sample and capturing it with a traditional, and low-cost, RGB camera. Moreover, we achieve a back-propagation reconstructed image, thus we can get back to the original photo by mapping the corresponding reflectivity photos of the three RGB channels5 p.application/pdfengcc-by-nc-nd (c) Allepuz, 2020http://creativecommons.org/licenses/by-nc-nd/3.0/es/Càmeres multiespectralsTreballs de fi de grauMultispectral cameraBachelor's thesesinfo:eu-repo/semantics/bachelorThesisinfo:eu-repo/semantics/openAccess
