Abstract

L'invention concerne un procédé et un appareil d'interaction de diffusion en direct. Selon l'invention, lorsqu'une instruction de visualisation prédéfinie est reçue, une image de vidéo en direct est considérée comme une image à reconnaître ; des informations de caractéristique de l'image à reconnaître sont extraites ; une recherche est effectuée pour déterminer si les informations de caractéristique existent dans une bibliothèque d'informations de caractéristique préétablie ; lorsque les informations de caractéristique existent dans la bibliothèque d'informations de caractéristique, des informations de marchandise d'un article correspondant aux informations de caractéristique sont présentées à l'utilisateur selon une manière d'affichage prédéfinie. Une image que l'utilisateur souhaite visualiser dans une zone de vidéo diffusée en direct est acquise, et les informations de caractéristique de l'image sont mises en correspondance avec les informations de caractéristique dans la bibliothèque d'informations de caractéristique, de façon à pouvoir déterminer s'il y a un article devant être affiché dans la zone, et lorsqu'il y a un article devant être affiché dans la zone de vidéo que l'utilisateur souhaite visualiser, les informations de marchandise de l'article sont présentées à l'utilisateur. On peut voir que, en utilisant une technologie de reconnaissance d'image pour identifier les informations de marchandise de l'article que l'utilisateur souhaite visualiser et en affichant les informations de marchandise de l'article à l'utilisateur, les informations de marchandise de l'article peuvent être affichées dans la diffusion en direct de manière naturelle, ce qui améliore l'expérience de l'utilisateur.
