Abstract

L'invention concerne un procédé et un système pour produire des photographies panoramiques pouvant être visionnées à l'aide d'un ordinateur personnel. Le procédé comprend les étapes suivantes : photographier un environnement avec un appareil numérique (20) comportant un objectif grand-angulaire (21), une première prise de vue étant effectuée, puis une seconde, après rotation de l'appareil dans un plan d'environ 180° ; monter des deux prises de vue en une photo panoramique ; réduire le volume de données-image et transférer la photo panoramique à volume de données réduit sur un support de publication, la photo étant insérée sous forme de panoramique pouvant être soumis à rotation ou à zoom sur un support de publication, notamment une page Internet. Le procédé et le système permettent de produire aisément et rapidement des panoramiques sphériques pour pages Internet interactives.
