Method and apparatus for collecting binoculus iris

Abstract

The invention relates to a method for collecting irises of both eyes and a corresponding device. At present, there is a problem that it is difficult to stably obtain an ideal iris image in iris recognition technology. The method of the present invention is as follows: firstly, the left and right eyeballs of the subject are placed in the left and right half-mirrors respectively; The vibration directions are perpendicular to each other; finally, the clear iris image is saved. At the same time, the invention provides the device used by the method. The invention makes full use of the physiological and physical characteristics of human eyes, so that the iris of both eyes and the imaging plane are kept parallel to each other during acquisition, and the obtained left and right iris images are symmetrical and stable during multiple acquisitions.

Description

technical field [0001] The invention belongs to the technical field of biological feature identification and information security, and in particular relates to a method and device for collecting irises of both eyes. Background technique [0002] Due to the inherent characteristics of biometrics (fingerprint, iris, face, etc.), biometric identification technology makes it possible to surpass and replace traditional identification technology, and has begun to be promoted in specific application fields in some countries and regions and use. Among them, iris recognition is particularly outstanding in the accuracy of identification, and because of its unique physiological structure, iris recognition technology has the potential to build a safer social environment. However, the excellent accuracy of iris recognition is based on the fact that the ideal iris image can always be collected, and it is difficult to guarantee such a basis in the actual application environment. the main...

Problems solved by technology

However, the excellent accuracy of iris recognition is based on the fact that the ideal iris image can always be collected, and it is difficult to guarantee such a basis in the actual application environment. The main difficulties faced in

This non-ideal iris image will bring two main problems for subsequent recognition: first, the diversity of different acquisitions of the same iris increases; second, the loss of effective information and the increase of interference information in a single acquisition

Existing iris recognition is based on the iris of a single eye. If a specific device is used to simultaneously collect the iris of the two eyes of the identified person, the stability of the collected iris image will be improved, and the above two problems will be effectively reduced. Detrimental impact of the problem on existing iris recognition performance

However, in the literature that has been published so far, there is no research on the method of simultaneously collecting people's binocular iris images and the corresponding collection devices.
