摘要： The present invention relates to an iris identification method and system, which divide an iris image, which is acquired for personal identification, into a plurality of equal/unequal and multiscale regions, generate a corresponding code corresponding to the respective regions, organizing codes into a database, generate a code at the time of authentication in the same manner, and identify a person by comparing this code with the codes stored in the database, thus improving identification speed and rate.The present invention provides an iris identification method including iris code registration and iris code authentication, the iris code registration including the steps of acquiring iris images by capturing iris using cameras or receiving image files, generating iris codes from the acquired iris images, and storing the generated iris codes in a database, the iris code authentication including the steps of acquiring an iris image in a manner identical to that of the iris code registration, generating an iris code from the acquired iris image, and identifying the generated iris code by comparing the generated iris code with the iris codes stored in the database, wherein the iris code generation step is performed in such a way as to determine the inner and outer boundaries of an iris region by approximating the inner and outer boundaries with general curves based on actual shapes of the inner and outer boundaries, divide a part or all of a region between the inner and outer boundaries into one or more unit sectors, and generate an iris code corresponding to the respective sectors, and the iris code identification step is performed in such a way as to measure the distances of the generated code to the existing codes stored in the database and determine whether each of the distances falls within a threshold value.

摘要翻译： 虹膜识别方法和系统本发明涉及一种虹膜识别方法和系统，其将获取的用于个人识别的虹膜图像分成多个相等/不等于多尺度区域，生成对应于各个区域的相应代码，将代码组织成 数据库，以相同的方式在认证时生成代码，并通过将该代码与存储在数据库中的代码进行比较来识别人，从而提高识别速度和速率。 本发明提供了一种虹膜识别方法，包括虹膜代码注册和虹膜代码认证，虹膜代码注册包括以下步骤：通过使用相机或接收图像文件捕获虹膜来获取虹膜图像，从所获取的虹膜图像生成虹膜代码，并且存储 生成虹膜代码，所述虹膜代码认证包括以与虹膜代码注册相同的方式获取虹膜图像的步骤，从所获取的虹膜图像生成虹膜代码，并通过比较所述虹膜代码来识别所生成的虹膜代码 产生具有存储在数据库中的虹膜代码的虹膜代码，其中虹膜代码生成步骤以这样的方式执行，以便通过基于实际形状的通用曲线逼近内部和外部边界来确定虹膜区域的内部和外部边界 在内边界和外边界之间划分内边界和外边界i之间的一部分或全部区域 n到一个或多个单位扇区，并且生成与相应扇区对应的虹膜代码，并且以这样的方式执行虹膜代码识别步骤，以便测量生成的代码与存储在数据库中的现有代码的距离，并确定是否 每个距离落在阈值内。
