Title (EN) METHOD AND SYSTEM FOR CODEC OF VISUAL FEATURE DATA
(FR) PROCÉDÉ ET SYSTÈME POUR UN CODEC DE DONNÉES DE CARACTÉRISTIQUES VISUELLES
(ZH) 用于视觉特征数据编解码的方法及系统
Abstract:
(EN) Disclosed by the present invention are a method and system for codec of visual feature data. The method comprises: an encoder receiving at least one type of first protocol format visual feature data generated by at least one type of intelligent front end and at least one certificate identity used to uniquely identify a corresponding at least one type of first protocol format and converting the at least one type of first protocol format visual feature data generated by the at least one type of intelligent front end to a same type of second protocol format visual feature data according to the at least one certificate identity; a decoder receiving the second protocol format visual feature data and parsing according to the second protocol format to obtain at least one type of original visual feature data which is generated by the at least one type of intelligent front end and which is contained in the at least one type of first protocol format visual feature data. At a minimum, the present invention avoids storing, in a server, different specifications used to describe different forms of visual feature data, and only the the specification of one type of protocol format needs to be stored in the server. Additionally, a back-end specification update operation is avoided.
(FR) La présente invention concerne un procédé et un système pour un codec de données de caractéristiques visuelles. Le procédé comprend les étapes suivantes : un codeur reçoit au moins un type de premières données de caractéristiques visuelles de format de protocole générées par au moins un type d'extrémité avant intelligente et au moins une identité de certificat utilisée pour identifier uniquement au moins un type correspondant d'un premier format de protocole et pour convertir le ou les types de premières données de caractéristiques visuelles de format de protocole générées par le ou les types d'extrémité avant intelligente en un même type de secondes données de caractéristiques visuelles de format de protocole en fonction de la ou des identités de certificat ; un décodeur reçoit les secondes données de caractéristiques visuelles de format de protocole et analyse selon le second format de protocole pour obtenir au moins un type de données de caractéristiques visuelles d'origine qui sont générées par le ou les types d'extrémité avant intelligente et qui sont contenues dans le ou les types de premières données de caractéristiques visuelles de format de protocole. Au minimum, la présente invention évite de stocker, dans un serveur, différentes spécifications utilisées pour décrire différentes formes de données de caractéristiques visuelles et seule la spécification d'un type de format de protocole doit être stockée dans le serveur. De plus, une opération de mise à jour de spécification d'extrémité arrière est évitée.
(ZH) 本发明公开了用于视觉特征数据编解码的方法及系统。所述方法包括:编码器接收至少一种智能前端产生的至少一种第一协议格式视觉特征数据和用于唯一地标识对应至少一种第一协议格式的至少一个证书标识,根据至少一个证书标识将至少一种智能前端产生的至少一种第一协议格式视觉特征数据转换为同一种第二协议格式视觉特征数据;解码器接收第二协议格式视觉特征数据,根据第二协议格式解析得到至少一种智能前端产生的、至少一种第一协议格式视觉特征数据所包含的至少一种原始视觉特征数据。至少避免了在服务器存储用于说明不同视觉特征数据形式的不同规范,仅仅需要在服务器存储一种协议格式的规范即可。而且,也避免了后端的规范更新操作。
