Abstract

The invention relates to a device for iris tracking and acquisition, and a method thereof and specifically relates to a device for remote iris tracking and acquisition, and a method thereof. An objective of the invention is to solve problems that an existing iris acquisition device cannot acquire information from long distance, that targets are needed to actively coordinate with the acquisition in an acquisition process, that the existing iris acquisition device is easy to be interfered by a plurality of targets, and that recognition algorithm precision is relatively low. A signal output end of a binocular camera is connected with a face information acquisition signal input end of a computer. A signal output end of a telephoto camera is connected with a signal input end of varied magnification and zoomed face information of the computer. A moving signal input end of a two-degree-of-freedom rotating holder is connected with a holder moving signal output end of the computer. An infrared source is fixed on the telephoto camera, and the telephoto camera is fixed on the two-degree-of-freedom rotating holder. The device and the method are used for remote iris tracking and acquisition.

Description

technical field

[0001] The invention relates to an iris tracking and collecting device and a method thereof, in particular to a long-distance iris tracking and collecting device and a method thereof. Background technique

[0002] Iris recognition technology is a kind of human biometric technology. The appearance of the human eye consists of three parts: sclera, iris, and pupil. The sclera is the white part of the eyeball, accounting for about 30% of the total area; the center of the eye is the pupil, accounting for about 5%; the iris is located between the sclera and the pupil, and contains the most abundant texture information, accounting for 65%. The formation of the iris is determined by genetics, and human gene expression determines the shape, physiology, color and overall appearance of the iris. When a person develops to about eight months, the iris basically develops to a sufficient size and enters a relatively stable period. Except for rare abnormal conditions, maj...
