Abstract

Il est décrit un appareil de détection dobjets, qui comprend une caméra ayant une sortie vidéo contenant des trames; et un processeur vidéo numérique, configuré pour recevoir la sortie vidéo en provenance de la caméra, et détecter et suivre une tache dans les trames afin de déterminer une trajectoire de la tache et de déclencher un message dalerte si la trajectoire de la tache est caractéristique de lobjet. Le processeur vidéo numérique peut détecter et classifier lobjet comme une fuite et fournir une alerte ou une alarme. Le processeur vidéo numérique peut détecter et classifier lobjet comme un oiseau et produire un rapport sur loiseau. Une station météorologique peut être combinée au processeur vidéo numérique afin de recevoir une entrée de la station météorologique et de prendre en compte lentrée de la station météorologique lors de la détermination pour savoir sil faut déclencher une alerte.
