Abstract

The invention relates to an iris identification device combining dynamic human eye tracking, effectively extending the distance and the angle of iris identification and also identifying multiple targets. The iris identification device combining dynamic human eye tracking utilizes two image collection devices: a wide-angle video camera is coordinated with a long-focus video camera. The iris identification device can utilize the wide-angle video camera to automatically catch targets within a working range so as to control a tripod head device to drive the long-focus video camera to aim at a target human eye, thus the focusing and the collection and the identification of iris images can be completed; assignment and alignment during the process can be achieved without any targets participation, the iris identification device is automatically regulated to complete the collection of the iris images in a coordinate way, thereby effectively realizing the identification and the verification of the iris images.

Description

Technical field

[0001] The invention relates to a remote iris recognition device used for identity verification. The device expands the range and angle of the iris recognition device by dynamically tracking the human eye. Background technique

[0002] Iris recognition has a wide range of applications in modern society. Iris recognition technology is a type of biometric technology that developed rapidly in the mid to late 1990s. Compared with other biometric technologies, it has the following characteristics: (1) Iris image passing The non-contact method can avoid the spread of diseases and is easy to be accepted; (2) The iris texture structure is not easy to be forged; (3) The iris texture structure is complex and the number of features is large, so iris recognition is considered to be the most reliable biometric recognition technology.

[0003] From a comprehensive perspective at home and abroad, the current application of iris identification technology is still in an immature s...
