Title (EN) METHOD FOR ASSISTING THE LOCATION OF A TARGET AND OBSERVATION DEVICE ENABLING THE IMPLEMENTATION OF THIS METHOD
(FR) PROCEDE D'AIDE A LA LOCALISATION D'UN OBJECTIF ET DISPOSITIF D'OBSERVATION PERMETTANT LA MISE EN ŒUVRE DE CE PROCEDE
Abstract:
(EN) The invention relates to a method for assisting the location of a target (24) for a first user equipped with an observation device (26) comprising an augmented reality observation means (11) associated with a first user reference frame (RU1). According to this method, a reference platform (1) associated with a master reference frame (RM) is positioned on the terrain, the reference platform is observed from at least one camera (13) worn by the first user, the geometry of the observed platform (1) is compared with a numerical model of same and the orientation and location of the first user reference frame (RU1) is deduced with respect to the master reference frame (RM). It is then possible to display, on an augmented reality observation means (11), at least one virtual reticle locating the target (24).
(FR) L'invention a pour objet un procédé d'aide à la localisation d'un objectif (24) pour un premier utilisateur équipé d'un dispositif d'observation (26) comportant un moyen d'observation (11) à réalité augmentée associé à un premier repère utilisateur (RU1). Suivant ce procédé on positionne sur le terrain une plateforme de référence (1) associée à un repère maître (RM), on observe la plateforme de référence à partir d'au moins une caméra (13) portée par le premier utilisateur, on compare la géométrie de plateforme (1) observée à un modèle numérique de celle-ci et on en déduit l'orientation et la localisation du premier repère utilisateur (RU1) par rapport au repère maître (RM). On peut ainsi afficher sur le moyen d'observation à réalité augmentée (11) au moins un réticule virtuel localisant l'objectif (24).
