Abstract

Les modes de réalisation de la présente invention facilitent l'étalonnage de caméras dans une scène d'action en direct à l'aide de drones. Selon certains modes de réalisation, un procédé configure une pluralité de caméras de référence pour observer au moins une partie de la scène d'action en direct. Le procédé configure en outre une ou plusieurs caméras mobiles ayant un mouvement non contraint pour observer un ou plusieurs objets mobiles dans la scène d'action en direct et pour observer au moins trois points de référence connus associés à la pluralité de caméras de référence. Le procédé reçoit en outre des données de point de référence en association avec la ou les caméras mobiles, les données de point de référence étant basées sur lesdits trois points de référence connus. Le procédé calcule en outre un emplacement et une orientation de chaque caméra mobile parmi la ou les caméras mobiles sur la base d'une ou de plusieurs des données de point de référence et d'un ou de plusieurs emplacements d'une ou de plusieurs caméras de référence de la pluralité de caméras de référence.
