Single-recognizer multi-gate access control device and method based on iris recognition

Abstract

The invention discloses a single-recognizer multi-gate access control device and method based on iris recognition. The device comprises a single iris recognizer and a multi-gate access controller, wherein the single iris recognizer comprises an iris acquiring module, a comprehensive information processing module and an acousto-optical prompting module; the multi-gate access controller comprises a multi-gate access control module and a digital keyboard module. The method comprises the following steps: acquiring an iris characteristic value code, comparing the iris characteristic value code with a pre-registered iris characteristic value code; judging whether the iris characteristic value code is in matching; inputting a to-be-opened gate number; processing multi-gate control information; judging whether the to-be-opened gate number is consistent with a pre-registered authorized opened gate number; opening a lock; and denying access. The multi-gate control is carried out through the single iris recognizer, the security and the reliability of the access control system are improved, and the cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of image processing, and further relates to an iris recognition-based single recognizer multi-door control access control device and method in the technical field of human biological feature recognition. The invention can be used in the occasion where the entrance gates of a specific area are relatively concentrated, and the single iris recognizer can realize the control and management of the personnel who are required to enter the specific area of ​​a plurality of gates equipped with iris recognition gates. Background technique [0002] Iris recognition is to determine people's identities by comparing the similarity between iris image features. Its core is to use pattern recognition, image processing and other methods to describe and match the iris features of human eyes, so as to realize automatic personal identity authentication. [0003] Wuxi Meiwang Network Information Technology Co., Ltd. has a patente...

Problems solved by technology

[0004] Although this patented technology has completed the authentication of access control personnel better, the disadvantage of the device disclosed in this patented technology is that there is no multi-door control device, and when used in a specific area where multiple doors are relatively concentrated, Each door should correspond to an iris recognition door control device

[0005] The disadvantage of the method disclosed in this patent technology is that there is no method for realizing multi-door control by a single iris recognizer, and it will cause request conflicts when multiple doors are simultaneously requested to be opened.

[0006] The above-mentioned shortcomings, in a specific area where there are multiple doors that are relatively concentrated, a door is required to correspond to a set of iris recognition door control devices, which increases user costs and causes waste of resources. If multiple doors are requested to be opened at the same time, the central server cannot Responding to multiple door opening requests at the same time will cause door opening request conflicts and reduce the reliability of the access control system
