Abstract
(EN) Disclosed are a biological feature recognition method and apparatus. The method comprises: acquiring registration data of a biological feature by using a first sensor, and generating a first image; converting the first image into a second image; generating template data on the basis of the first image and the second image; acquiring data to be recognized of the biological feature by using the first sensor or a second sensor; and matching the data to be recognized with the template data, so as to obtain a recognition result. By means of the present application, the effect facilitating usage thereof is achieved without the need to perform multiple instances of registration on multiple sensors.
(FR) Sont décrits un procédé et un appareil de reconnaissance de caractéristique biologique. Le procédé consiste à : acquérir des données d'enregistrement d'une caractéristique biologique en utilisant un premier capteur, et générer une première image ; convertir la première image en une seconde image ; générer des données de modèle sur la base de la première image et de la seconde image ; acquérir des données à reconnaître de la caractéristique biologique en utilisant le premier capteur ou un second capteur ; et mettre en correspondance les données à reconnaître avec les données de modèle, de manière à obtenir un résultat de reconnaissance. Au moyen de la présente demande, l'effet facilitant son utilisation est obtenu sans qu'il soit nécessaire d'effectuer de multiples instances d'enregistrement sur de multiples capteurs.
(ZH) 本申请公开了一种生物特征识别方法和装置。该方法包括:使用第一传感器获取生物特征的注册数据,并生成第一图像;将第一图像转换为第二图像;基于第一图像和第二图像生成模板数据;使用第一传感器或第二传感器获取生物特征的待识别数据;将待识别数据与模板数据进行匹配,获得识别结果。通过本申请,达到了无需对多个传感器多次注册方便使用的效果。
