Abstract

Sont divulgués un procédé et un appareil permettant d'appeler un terminal, ainsi qu'un dispositif électronique et un support d'enregistrement. Le procédé consiste : à obtenir une image cible ; à déterminer un point de repère cible dans l'image cible, le point de repère cible constituant un point de repère correspondant à un objet d'appel cible dans l'image cible ; à déterminer une relation de position relative entre le point de repère cible et un appareil de collecte d'image cible en fonction de la position du point de repère cible dans l'image cible, de paramètres de dispositif de l'appareil de collecte d'image cible, et de paramètres d'installation de l'appareil de collecte d'image cible ; à déterminer la position géographique du point de repère cible en fonction de la position géographique de l'appareil de collecte d'image cible et de la relation de position relative ; et à déterminer un terminal cible en fonction de la position géographique du point de repère cible, et à lancer un appel vers le terminal cible. Selon la solution technique divulguée dans la présente demande, un appel peut être rapidement lancé vers l'objet d'appel cible.
