Title
(EN) SUBJECT SENSING IN AN ENVIRONMENT
(FR) DÉTECTION DE SUJETS DANS UN ENVIRONNEMENT
Abstract
(EN)
A multimodal sensor network is designed to extract a plurality of fundamental properties associated wit subject sensing. In one aspect, such network can combine cameras distributed in an environment with inertial sensors available in subjects' wearable devices. The network can permit anonymous detection, counting, and localization of one or more subjects utilizing the cameras. In one aspect, by fusing such information with positional data from the inertial sensors contained or coupled to wearable devices associated with the one or more subjects, the network can track and can identify each subject carrying a wearable device functionally coupled to inertial sensor(s). In one aspect, the problem of subject sensing can be divided into two parts: (1) a detection, counting, and localization (DCL) layer and (2) a tracking and identification (TI) layer, wherein such layers can be implemented via simulations and a real sensor network deployment.

Réseau de capteurs multimodal conçu pour extraire plusieurs propriétés fondamentales associées à la détection de sujets. Selon un aspect de l'invention, un tel réseau peut combiner des caméras distribuées dans un environnement avec des capteurs à inertie présents dans les dispositifs pouvant être portés par les sujets. Le réseau peut permettre la détection anonyme, le comptage et la localisation d'un ou plusieurs sujets à l'aide de caméras. Dans un mode de configuration, en fusionnant de telles informations avec des données de position des capteurs à inertie contenus ou couplés aux dispositifs portables associés au(x) sujet(s), le réseau peut repérer et identifier chaque sujet portant un dispositif portable couplé d'une manière fonctionnelle au(x) capteur(s) à inertie. Dans un mode de configuration, le problème de la détection du sujet peut être divisé en deux parties : (1) une couche de détection, de comptage et de localisation (DCL), et (2) une couche de suivi et d'identification (TI), de telles couches pouvant être implantées par le biais de stimulations et d'un déploiement d'un réseau de capteurs réel.
