Abstract

La présente invention concerne un système d'appel d'ascenseur intelligent fondé sur la reconnaissance faciale. Ledit système comprend un module d'enregistrement préalable, un module de reconnaissance et de comparaison et un module de sortie d'instruction d'appel d'ascenseur. Le module d'enregistrement préalable effectue un enregistrement préalable, acquiert des images faciales entrées et les mémorise, les images faciales acquises étant des images faciales vérifiées de résidents. Le module de reconnaissance et de comparaison acquiert une image faciale d'un certain passager qui souhaite appeler un ascenseur, et effectue une reconnaissance et une comparaison fondées sur des informations d'images faciales préalablement mémorisées dans le module d'enregistrement préalable ; si la comparaison est réussie, le module envoie un signal de seuil de tension au module de sortie d'instruction d'appel d'ascenseur ; et si la comparaison n'est pas réussie, il n'envoie pas de signal de seuil de tension au module de sortie d'instruction d'appel d'ascenseur. Le module de sortie d'instruction d'appel d'ascenseur reçoit le signal de seuil de tension envoyé par le module de reconnaissance et de comparaison et délivre une instruction d'appel d'ascenseur. Le système d'appel d'ascenseur intelligent fondé sur la reconnaissance faciale permet de résoudre les complications d'un appel d'ascenseur conventionnel et d'améliorer les autorisations de sécurité ; le système ne permet qu'à des passagers enregistrés d'utiliser l'ascenseur ; et le système reconnaît et confirme les passagers enregistrés au moyen d'un système de reconnaissance faciale, et après confirmation, délivre une instruction d'appel d'ascenseur pour appeler un ascenseur.
