Access control system based on face recognition

Abstract

The invention relates to the technical field of access control, in particular to an access control system based on face recognition. The system comprises a camera module, a sidewalk gate, a road gate and a controller. In the operation process of a community face recognition access control, the situation that a visitor and a vehicle license plate are not recognized at the first attempt often occurs, the visitor and the vehicle need to enter a recognition area again, and the operation efficiency of a face recognition access control system is influenced. In the process in which the vehicle is recognized again, the speed of the vehicle which shifts gears and advance again is low, and if the roadway gate falls down in advance at the moment, the risk of damaging the vehicle can be caused. Therefore, an object entering the access control system is recognized twice through a main recognition unit and an auxiliary recognition unit which are arranged in the camera module, and collision damage caused by a road bar when a vehicle does not leave a barrier gate and descends is reduced by utilizing a damping air bag mounted at the bottom of a vertical rod, so that the operation effect of the access control system based on face recognition is improved.

Description

technical field [0001] The invention relates to the technical field of access control, in particular to an access control system based on face recognition. Background technique [0002] Smart cities can effectively assist the government to improve the level of urban governance. On the one hand, relying on the construction of the "urban brain", the government can lower urban management to micro-units such as communities and parks on the premise of consolidating the construction of information infrastructure. Through real-time management , traceability management, predictive management and other means to realize the intelligent, three-dimensional and precise governance of the city. On the other hand, with the penetration of urban governance in the fields of community health, public security, and social service management, the government can achieve collaboration and innovation in organizational structure, operating mechanism, and service processes, and integrate and share vari...

Problems solved by technology

[0003] Among them, the smart community has become a hot project in the last 100 meters of smart city construction, and the smart access control system is particularly important as the first barrier of the smart community, although the current access control system is gradually changing from smart card recognition to face recognition; However, during the operation of the face recognition access control in the community, it often happens that the visitor and the vehicle license plate are not recognized once, and the person and the vehicle need to re-enter the recognition area, which affects the operating efficiency of the face recognition access control system. During the process of re-identification, the speed of the vehicle moving again after shifting gears is low. If the gate of the roadway falls early at this time, it will cause the risk of damage to the vehicle

[0004] For example, a Chinese patent with application number CN201711353273.4 discloses an access control system and method based on face recognition. The access control system includes a first trigger module, a second trigger module, a first image processing module, and a second image processing module. and facial feature comparison module; the first image acquisition module collects the whole-body image of the person in the first trigger area, and the second image acquisition module collects the face image of the person in the second trigger area, processes the whole-body image and corrects the parameters, and compares with the pre-stored All contour information is compared, and all pre-stored facial images in the correction interval are screened out, matched and fused with the collected facial images. The facial feature comparison module controls the unlocking of the access control according to the matching degree of the facial images. At the same time, the access control system passes The sensor module senses the entry and exit of people to realize timely playback and interruption of advertisements. This technical solution can quickly and accurately perform image recognition, reduce the delay of the response time of the access control system, accurately realize the switching of advertisements, improve the working efficiency of the access control system, and facilitate property management. management; however, in this technical solution, there is no measure to restrict the vehicles that forcibly break into the access control system, which makes the access control system have security problems
