Embodiment

[0076] see Figure 4 , we use the mask mask face dataset (RMFD) of Wuhan University, including (1) real mask face recognition dataset: samples crawled from the network, after sorting, cleaning and labeling, 5,000 masks containing 525 people face, 90,000 normal faces. (2) Face recognition data set with simulated masks: put masks on the faces in the public data set, and obtain a simulated mask face data set with 10,000 faces and 500,000 faces.

[0077] The evaluation indicators of the face recognition module performance test mainly include: precision rate, recall rate and time delay. Therefore, the following will combine the test set to test the precision rate, recall rate and time delay of the face recognition module to comprehensively analyze the performance of the face recognition module.

[0078] The face recognition module mainly includes three modules: video key frame extraction, mask detection and face feature extraction, and face recognition. The time delay is mainly g...

Abstract

The invention belongs to the technical field of access control systems, and particularly relates to an intelligent access control epidemic prevention system based on face recognition. The system comprises an initialization interface, a user management module, a mask detection module and a face recognition module. Each functional module is displayed in an interface after the initialization interface is entered, and the modules are clicked to realize functions; and the user management module has background administrator authority to manage resident information, and can perform information entry,information query, information modification and information deletion functions on the user in the background. According to the intelligent access control epidemic prevention system based on face recognition, the face recognition technology is used for recognizing a mask and a normal face, then judgment output is carried out at the decision level, the whole system can achieve the intelligent access control system with multi-layer safety control, and therefore the safety of traditional access control is improved, and the intelligent access control epidemic prevention system based on face recognition has high application value.

Description

technical field [0001] The invention relates to the technical field of access control systems, in particular to an intelligent access control and epidemic prevention system based on face recognition. Background technique [0002] At present, affected by the global pandemic of the novel coronavirus, how to do a good job of personnel identity authentication and identification "efficiently, quickly and safely" has become a research hotspot. With the rapid development of today's digital information society, the level of security information in buildings and communities has gradually increased. [0003] Biometric technology is defined as a technology that uses human biometrics for identity authentication. To be precise, biometrics recognition technology is a means to extract the inherent physiological and behavioral characteristics of human organisms for identification through the combination of computer and acoustics, optics, biosensors and biostatistical principles. Biometric...
