Abstract: Recovery of surface spectral reflectance is impossible exclusively with conventional RGB cameras.The appearance of a captured image depends on both the illumination spectrum and the spectral reflectances of objects in the scene. Even if the illumination spectrum is known, an RGB camera provides only 3 measurements which is insufficient to recover the spectral reflectance
This paper constructs a set of multi-spectral imaging camera system, which consists of 12 DHHV1300FM cameras. And eleven len are installed with filters with different wavelengths. The paper proposes an algorithm of multi-spectral imaging system based on group of camera to recover the spectral reflectance of the scene efficiently and robustly, that combines with the advantages of using multiple spectral sources and the groups of multispectral camera. Finally, simulation verifies the validity of this system.
