Abstract

This contribution presents a fusion method for spectral series with the main purpose of obtaining 3D information. The image series to be fused are combined stereo and spectral series gained with a camera array. Therefore, in order to register them, features that are invariant with respect to the varying gray values in the spectral images are extracted. The proposed approach is region based and uses characteristics like size, position and shape for registration. The regions are identified using the watershed transformation. The fusion problem is modeled using energy functionals that are to be optimized. They take into consideration the size, position, shape and correlation of the regions. Using the implemented algorithm, several scenes have been reconstructed. The experimental results show that the proposed method delivers reliable and accurate dense depth maps of combined stereo and spectral series.
