Abstract

L'invention concerne un procédé et un dispositif d'acquisition d'image, et un procédé et un système de surveillance vidéo. Un procédé d'acquisition d'image est appliqué dans un dispositif d'acquisition d'image d'un système de surveillance vidéo. Le dispositif d'acquisition d'image comprend un capteur Wi-Fi et un module de capture d'image. Le procédé consiste à : acquérir, au moyen du module de capture d'image, une image humaine comprenant une caractéristique de corps humain dans un environnement cible ; obtenir, au moyen du capteur Wi-Fi, des informations d'identification uniques d'au moins un terminal Wi-Fi situé dans l'environnement cible ; associer l'image humaine et les informations d'identification uniques du ou des terminaux Wi-Fi afin de générer des données d'image à partir de l'image humaine comprenant la caractéristique de corps humain et les informations d'identification uniques. Comparée à l'état de la technique qui comprend uniquement l'acquisition et la sortie d'image, la présente invention permet d'obtenir une plus grande quantité de données de surveillance qui serviront de base à l'exécution d'une analyse d'alerte précoce automatique.
