Abstract
(EN)
A merchandise category recognition method, apparatus, and electronic device, the method comprising: acquiring a target image of a merchandise region contained in an unmanned vending machine (S110); performing merchandise feature recognition on the target image to obtain a target feature vector of target merchandise contained in the target image (S120); determining from a preset reference feature vector library a first reference feature vector that matches the target feature vector (S130); and determining a merchandise category corresponding to the first reference feature vector to be the merchandise category of the target merchandise (S140). The described method may shorten the time spent on updating a new category of merchandise, thereby improving the overall efficiency of merchandise category recognition.
(FR)
L'invention concerne un procédé, un appareil et un dispositif électronique de reconnaissance de catégorie de marchandise, le procédé consistant : à acquérir une image cible d'une région de marchandise contenue dans un distributeur automatique (S110) ; à réaliser une reconnaissance de caractéristiques de marchandise sur l'image cible pour obtenir un vecteur cible de caractéristiques de marchandise cible contenu dans l'image cible (S120) ; à déterminer, à partir d'une bibliothèque prédéfinie de vecteurs de caractéristiques de référence, un premier vecteur de caractéristiques de référence qui correspond au vecteur cible de caractéristiques (S130) ; et à déterminer une catégorie de marchandise correspondant au premier vecteur de caractéristiques de référence comme étant la catégorie de marchandise de la marchandise cible (S140). Le procédé décrit peut réduire le temps passé à mettre à jour une nouvelle catégorie de marchandise, ce qui permet d'améliorer l'efficacité globale de la reconnaissance de catégorie de marchandise.
