Multispectral image capture using two RGB cameras

Raju Shrestha, Jon Yngve Hardeberg

Abstract: The development of faster and more cost effective acquisition systems is very important for the widespread use of multi-spectral imaging. This paper studies the feasibility of using two commercially available RGB cameras, each equipped with an optical filter, as a six channel multispectral image capture system. The main idea is to pick the best pair of filters from among readily available filters that modifies the sensitivities of the two cameras in such a way that their dominant wavelengths spread well spaced throughout the visible spectrum. Simulations with reasonably large number of available filters show encouraging result clearly indicating the possibility of using such systems.
