Title
(EN) MOTION DETECTION DEVICE AND METHOD
(FR) DISPOSITIF DE DÉTECTION DE MOUVEMENT ET PROCÉDÉ
Abstract
(EN)
A motion detection device is provided. The motion detection device includes a first dynamic vision sensor (DVS), a memory, a communication circuit, and at least one processor, wherein the at least one processor is configured to receive a plurality of images including a movable object using the first DVS for a predetermined time, generate data for determining a kind of motion of the moveable object based on a motion vector of the plurality of images, transmit the generated data to a cloud, and determine the kind of motion of the moveable object based on information received from the cloud.
(FR)
La présente invention concerne un dispositif de détection de mouvement. Le dispositif de détection de mouvement comprend un premier capteur de vision dynamique (DVS), une mémoire, un circuit de communication, et au moins un processeur, le au moins un processeur étant configuré pour recevoir une pluralité d'images comprenant un objet mobile à l'aide du premier DVS pendant un temps prédéterminé, générer des données pour déterminer un type de mouvement de l'objet mobile sur la base d'un vecteur de mouvement de la pluralité d'images, transmettre les données générées à un nuage, et déterminer le type de mouvement de l'objet mobile sur la base d'informations reçues provenant du nuage.
