Embodiment Construction

[0011] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0012] like figure 1 Shown: the present invention includes image acquisition equipment, sound acquisition equipment, electronically controlled door locks, access controllers, data processors and sound and light alarms.

[0013] Multi-biological feature fusion refers to the use of different characteristics of biological features to carry out fusion at a certain level, the purpose of which is to overcome or avoid the limitations of a single feature; . By combining different biometric information for fusion authentication, the influence of unfavorable factors is reduced, and an effective solution is brought to solve the shortage of single-modal biometric identification. Face image and sound information are relatively unique and stable, and are convenient to collect, non-contact and non-invasive. It is suitable for use as an identification feature in access cont...

Abstract

The invention relates to a multiple biological characteristic identification-based intelligent door control system, which comprises a voice acquisition device and an image acquisition device, wherein a door controller receives a voice signal and a human face image signal acquired by the image acquisition device respectively; the output end of the door controller is connected with a data processor and an electric control door lock respectively; the door controller transmits the received voice signal and the human face image signal into the data processor; the data processor extracts characteristics from the received voice signal and the human face image signal respectively, performs identification according to the acquired voice signal and the human face image signal and performs normalization and classification fusion treatment on the corresponding signals after the characteristics are extracted; the data processor compares the corresponding signals obtained after the classification fusion treatment with a preset sample base; and when the signals obtained after the classification fusion treatment are matched with the corresponding signals in the sample base, the door controller opens the electric control door lock. The multiple biological characteristic identification-based intelligent door control system improves the reliability of identification, has high accuracy and is convenient in identification, safe and reliable.

Description

technical field [0001] The invention relates to an access control system, in particular to an intelligent access control system based on multi-biological feature identification, which belongs to the technical field of access control systems. Background technique [0002] At present, the identification methods of the traditional access control system include passwords, passwords, certificates and so on. Due to the separability from the identified person, it is easy to cause forgery, misappropriation, deciphering and other phenomena. The biological attributes of the human body are unique to the human body, and some biological attributes such as fingerprints, irises, and voices are unique. Applying them to the access control system can prevent forgery and embezzlement. Biometric recognition technology is mainly divided into two categories: one is physiological feature recognition, which uses fingerprints, palms, irises, retinas and faces for recognition; the other is behaviora...
