Abstract

We propose in this paper an active vision approach forperforming the 3D reconstruction of static scenes. Theperception-action cycles are handled at various levels: from thedefinition of perception strategies for scene exploration downto theautomatic generation of camera motions using visual servoing. Toperform the reconstruction, we use a structure from controlled motionmethod which allows an optimal estimation of geometrical primitiveparameters. As this method is based on particular camera motions,perceptual strategies able to appropriately perform a succession ofsuch individual primitive reconstructions are proposed in order torecover the complete spatial structure of the scene. Two algorithmsare proposed to ensure the exploration of the scene. The former isan incremental reconstruction algorithm based on the use of aprediction/verification scheme managed using decision theory andBayes nets. It allows the visual system to get a high leveldescription of the observed part of the scene. The latter, based onthe computation of new viewpoints ensures the complete reconstructionof the scene. Experiments carried out on a robotic cell havedemonstrated the validity of our approach.
