Abstract

The invention relates to the technical field of artificial intelligence, and particularly discloses an iris recognition method and device, and the method comprises the steps of obtaining the standardized three-dimensional iris image data of a to-be-recognized iris; subjecting the standardized three-dimensional iris image data to feature extraction and classification through a two-dimensional convolutional neural network, obtaining target feature data and target user tags corresponding to the to-be-recognized iris, wherein the two-dimensional convolutional neural network comprises a three-dimensional image processing layer, the three-dimensional image processing layer carries out dimension reduction processing on the standardized three-dimensional iris image data to obtain a plurality of pieces of two-dimensional iris image data, and the plurality of pieces of two-dimensional iris image data comprise oblique section data; calling the iris feature data corresponding to the target user tag from a three-dimensional iris image database, and wherein the iris feature data of each user in the multiple users is stored in the three-dimensional iris image database; and generating an iris recognition result according to the target feature data and the called iris feature data. According to the scheme, the iris recognition accuracy can be improved.

Description

technical field [0001] The present application relates to the technical field of artificial intelligence, in particular to an iris recognition method and device. Background technique [0002] At present, iris recognition technology solutions mainly focus on the processing of two-dimensional digital images, for example, using local binary pattern (Local Binary Pattern, LBP) algorithm, support vector machine (Support Vector Machine, SVM) algorithm, filter, two-dimensional Convolutional Neural Networks (CNN) algorithm and various improved algorithms. [0003] No matter what algorithm is used or how to optimize the algorithm, the core features required by the algorithm are extracted based on the two-dimensional image of the iris. Two-dimensional convolutional neural network is the most widely used algorithm in existing two-dimensional image processing methods. For a certain type of feature, a 2×2 two-dimensional convolution kernel can only extract data features in 4 directions...
