Title
(EN) PEDESTRIAN RECOGNITION METHOD AND DEVICE
(FR) PROCÉDÉ ET DISPOSITIF DE RECONNAISSANCE DE PIÉTON
(ZH) 一种行人识别方法及装置
Abstract
(EN)
A pedestrian recognition method and device. The method comprises: acquiring image features of a target pedestrian image, the image features comprising facial features and body features (S101); acquiring from a feature database at least one target node of the image features, and using a pedestrian image that corresponds to the at least one target node as an image of a target pedestrian (S103); the feature database comprises multiple pedestrian feature nodes, and the pedestrian feature nodes comprise facial features and body features which correspond to a pedestrian image, as well as relationship features between other pedestrian feature nodes. The described method enables the amount of computation for pedestrian searching to be greatly reduced, which improves searching efficiency.

La présente invention concerne un procédé et un dispositif de reconnaissance de piéton. Le procédé consiste : à acquérir des caractéristiques d'image d'une image de piéton cible, les caractéristiques d'image comprenant des caractéristiques de visage et des caractéristiques de corps (S101); à acquérir d'une base de données de caractéristiques au moins un nœud cible des caractéristiques d'image, et à utiliser une image de piéton qui correspond auxdits nœuds cibles en tant qu'image d'un piéton cible (S103); la base de données de caractéristiques comprend de multiples nœuds de caractéristique de piéton, et les nœuds de caractéristique de piéton comprennent des caractéristiques de visage et des caractéristiques de corps qui correspondent à une image de piéton, ainsi que des caractéristiques de relation entre d'autres nœuds de caractéristique de piéton. Le procédé décrit permet de réduire considérablement la quantité de calcul relative à la recherche de piéton, ce qui améliore l'efficacité de recherche.

一种行人识别的方法及装置。所述方法包括:获取目标行人图像的图像特征,所述图像特征包括人脸特征和人体特征(S101);从特征数据库中获取所述图像特征的至少一个目标节点,并将所述至少一个目标节点分别对应的行人图像作为所述目标行人的图像(S103);其中,所述特征数据库中包括多个行人特征节点,所述行人特征节点中包括行人图像对应的人脸特征、人体特征以及与其他行人特征节点之间的关系特征。该方法可以大大降低行人搜索的计算量,提高搜索效率。
