Abstract
La présente invention porte sur un procédé et un appareil de positionnement visuel, un dispositif électronique et un support de stockage. Le procédé consiste à extraire un vecteur de caractéristiques d'un point caractéristique d'une image d'interrogation (S11); à rechercher, en fonction du vecteur de caractéristiques du point caractéristique de l'image d'interrogation, un point caractéristique de base de données qui correspond au point caractéristique de l'image d'interrogation, le point caractéristique de base de données représentant un point caractéristique d'une image de base de données (S12); et à déterminer un résultat de positionnement visuel de l'image d'interrogation selon le point caractéristique de base de données mis en correspondance (S13).
