Abstract

La présente invention concerne un procédé et un appareil de surveillance de sécurité d'un serre. Le procédé consiste à : surveiller une zone de surveillance de sécurité prédéterminée dans une serre; émettre un message d'invite qui invite une cible mobile à effectuer un geste de vérification lors de la surveillance de la cible mobile dans la zone de surveillance de sécurité; capturer et reconnaître le geste de vérification effectué par la cible mobile; déterminer si le geste de vérification correspond à au moins un geste valide d'une bibliothèque de gestes prédéfinie ; et émettre des informations d'alarme si ce n'est pas le cas. Par application de la solution technique fournie par les modes de réalisation de la présente invention, il n'est pas nécessaire d'avoir une personne dédiée pour accorder continuellement une attention à un enregistrement de vidéo surveillance, ce qui permet de réduire le coût de la main-d'oeuvre, d'assurer la sécurité des plantes poussant dans une serre sans qu'il ne soit nécessaire de prendre soin des plantes et d'éviter les pertes économiques d'un utilisateur provoquées par des dommages aux plantes.
