Abstract

Ce système comporte : au moins un dispositif de suivi (141,...14n), recevant un flux vidéo et configurable dynamiquement, conçu pour la détection et le suivi automatique d'au moins une cible par analyse du flux vidéo ; un calculateur (20) de valeur métrique de performance à partir d'un résultat de suivi de cible (R1,...Rn) fourni par le dispositif de suivi (141,...14n) ; un correcteur (26) de paramètre de configuration du dispositif de suivi (141,...14n) en fonction de la valeur métrique de performance ; et un configurateur dynamique (161,...16n) du dispositif de suivi (141,...14n) par application du paramètre de configuration corrigé. Il comporte en outre un dispositif de suivi supplémentaire de référence (14MSTR), recevant au moins une portion du flux vidéo, et le calculateur (20) calcule la valeur métrique de performance à partir d'une comparaison, sur la portion de flux vidéo, du résultat de suivi de cible (R1,..., Rn) fourni par le dispositif de suivi (141,..., 14n) et d'un résultat de suivi de référence (S1,..., Sn) fourni par le dispositif de suivi supplémentaire de référence (14MSTR).This system comprises: at least one tracking device (141,...14n), receiving a video stream and dynamically configurable, designed for the detection and automatic tracking of at least one target by analyzing the video stream; a performance metric value calculator (20) based on a target tracking result (R1,...Rn) provided by the tracking device (141,...14n); a corrector (26) for the configuration parameter of the tracking device (141,...14n) as a function of the performance metric value; and a dynamic configurator (161,...16n) of the tracker (141,...14n) by applying the corrected configuration parameter. It further comprises an additional reference tracking device (14MSTR), receiving at least a portion of the video stream, and the calculator (20) calculates the performance metric value from a comparison, on the video stream portion, the target tracking result (R1,..., Rn) provided by the tracking device (141,..., 14n) and a reference tracking result (S1,..., Sn) provided by the additional reference tracking device (14MSTR).
