Abstract

The embodiment of the invention discloses an iris detection method of living body, and a terminal. The method comprises: a plurality of iris photos are obtained; a position of a center of a pupil in each iris photo is determined; according to the position of the center of the pupil in each iris photo, a maximum displacement value of the center of the pupil is calculated; and according to the maximum displacement values of the centers of the pupils, an iris detection result is determined. According to the embodiment of the invention, the iris detection accuracy and identification efficiency are improved; and the eyes can be protected from being injured.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a living iris detection method and a terminal. Background technique [0002] Iris recognition technology can be used for identity recognition. A key point of iris recognition technology is the detection of living iris. The system needs to distinguish whether the collected iris photo is from a living body or from an eye photo. In the existing technical solutions, in order to solve the live detection problem of iris recognition, most of them are realized by analyzing the texture, defocus, frequency distribution and other aspects of the collected iris photos through image recognition technology, but this method needs to carry out A series of calculations with high complexity such as wavelet transform, and there is a certain error rate. In addition, in the existing technical scheme, the strength of the light irradiating the eyes can also be adjusted, and multiple photos of the i...
