Robust Depth Estimation by Fusion of Stereo and Focus Series Acquired with a Camera Array

In order to obtain depth information from intensity sensors without auxiliary means, an image series is needed, gathered by varying at least the geometrical or focus position of the camera. Each of the fusion methods imposes certain constraints on the observed scene. With the aim of alleviating these restrictis, this contribution presents an algorithm to fuse combined stereo and focus series using energy functionals. A camera array is employed to record the series of images simultaneously.
