Cependant, afin de mettre en \u0153uvre de tels syst\u00E8mes, diff\u00E9rentes probl\u00E9matiques doivent \u00EAtres trait\u00E9es. Parmi elle, la localisation repr\u00E9sente l\u2019une des plus importantes. En effet, l\u2019estimation de la position et de l\u2019orientation (appel\u00E9e pose) du point de vue (de la cam\u00E9ra ou de l\u2019utilisateur) permet de recaler les objets virtuels sur les parties observ\u00E9es de la sc\u00E8ne r\u00E9elle. Dans nos travaux de th\u00E8se, nous pr\u00E9sentons un syst\u00E8me de localisation original destin\u00E9 \u00E0 des environnements \u00E0 grande \u00E9chelle qui utilise une approche bas\u00E9e vision sans marqueur pour l\u2019estimation de la pose de la cam\u00E9ra. Cette approche se base sur des points caract\u00E9ristiques naturels extraits des images. Etant donn\u00E9 que ce type d\u2019approche est sensible aux variations de luminosit\u00E9, aux occultations et aux mouvements brusques de la cam\u00E9ra, qui sont susceptibles de survenir dans l\u2019environnement ext\u00E9rieur, nous utilisons deux autres types de capteurs afin d\u2019assister le processus de vision. Dans nos travaux, nous voulons d\u00E9montrer la faisabilit\u00E9 d\u2019un sch\u00E9ma de suppl\u00E9ance dans des environnements ext\u00E9rieurs \u00E0 large \u00E9chelle. Le but est de fournir un syst\u00E8me palliatif \u00E0 la vision en cas de d\u00E9faillance permettant \u00E9galement de r\u00E9initialiser le syst\u00E8me de vision en cas de besoin. Le syst\u00E8me de localisation vise \u00E0 \u00EAtre autonome et adaptable aux diff\u00E9rentes situations rencontr\u00E9es." .

<http://www.idref.fr/216758912/id>	<http://www.w3.org/2004/02/skos/core#note>	"The democratization of mobile devices such as smartphones, PDAs or tablet-PCs makes it possible to use Augmented Reality systems in large scale environments. However, in order to implement such systems, many issues must be adressed. Among them, 3D localization is one of the most important. Indeed, the estimation of the position and orientation (also called pose) of the viewpoint (of the camera or the user) allows to register the virtual objects over the visible part of the real world. In this paper, we present an original localization system for large scale environments which uses a markerless vision-based approach to estimate the camera pose. It relies on natural feature points extracted from images. Since this type of method is sensitive to brightness changes, occlusions and sudden motion which are likely to occur in outdoor environment, we use two more sensors to assist the vision process. In our work, we would like to demonstrate the feasibility of an assistance scheme in large scale outdoor environment. The intent is to provide a fallback system for the vision in case of failure as well as to reinitialize the vision system when needed. The complete localization system aims to be autonomous and adaptable to different situations. We present here an overview of our system, its performance and some results obtained from experiments performed in an outdoor environment under real conditions." .
