Foveated vision systems with two cameras per eye

Abstract

In this paper we discuss active humanoid vision systems that realize foveation using two rigidly connected cameras in each eye. We present an exhaustive analysis of the relationship between the positions of the observed point in the foveal and peripheral view with respect to the intrinsic and extrinsic parameters of both cameras and 3-D point position. Based on these results we propose a control scheme that can be used to maintain the view of the observed object in the foveal image using information from the peripheral view. Experimental results showing the effectiveness of the proposed foveation control are also provided.
