Embodiment Construction

[0028] The iris recognition method provided by each embodiment of the present invention can be executed by a mobile terminal in the form of software and / or hardware. The mobile terminal may include, for example: a terminal device with an iris recognition function, such as a tablet computer, a mobile phone, and the like.

[0029] Embodiment 1 of the present invention provides an iris recognition method. figure 1 It is a flow chart of an iris recognition method provided by Embodiment 1 of the present invention. Such as figure 1 Shown, this iris recognition method can comprise the steps:

[0030] S101. According to the distance between the human eye and the camera whose iris is to be collected, determine the current intensity corresponding to the distance between the human eye and the camera as the first current intensity.

[0031] Specifically, due to the different distances between the human eye and the camera, the intensity of infrared light required to obtain the preset ir...

Abstract

The invention provides an iris recognition method and apparatus, and a mobile terminal. The method comprises steps of determining a corresponding current intensity between a human eye and a camera to be a first current intensity according to the distance between the human eye whose iris is to be acquired and the camera; supplying power to an infrared light according to the first current intensity so that the infrared light emits infrared light; collecting an iris image of the human eye under irradiation of the infrared light; and carrying out iris recognition according to the iris image. The method can improve the accuracy of iris recognition.

Description

technical field [0001] The invention relates to the technical field of identification, in particular to an iris identification method, device and mobile terminal. Background technique [0002] As one of the important biological characteristics of the human body, the iris is unique, invariant and non-replicable, so that the application of iris recognition in the field of recognition can guarantee high security. [0003] As a biometric technology, iris recognition can obtain iris features based on the collected iris image, compare the extracted iris features with the features in the preset iris feature database, and determine the recognition result. The quality of the iris image plays a crucial role in the security level of iris recognition. In order to improve the quality of the iris image, the iris image can be collected under the irradiation of infrared light. That is, when performing iris recognition, a preset current intensity is used to drive infrared light for irradia...
