Community access control system based on face recognition

Abstract

A community access control system based on face recognition is characterized by comprising a face information database, an image acquisition module, a face detection module and a face recognition module. The face information database is used for storing face images and feature data of permanent residents in a community. The image acquisition module is used for acquiring face video information of the residents and obtaining face pictures from the face video information. The face detection module conducts preprocessing on the face pictures to obtain a face image sequence. The face recognition module conducts facial feature extraction on the face image sequence of the face detection module, obtains face feature data, matches the face feature data with the feature data in a face feature database, and outputs matching results. According to the community access control system based on the face recognition, a face recognition software system is divided into three mutually independent modules, namely the face detection module, the face recognition module and the face information database, so that the face recognition software system is stable in recognition and high in running speed. Meanwhile, through preprocessing of collected image information, the overall community access control system can overcome the influence of illumination variation, and therefore quite high recognition can be realized no matter in what kind of light environment.

Description

technical field [0001] The invention relates to a community access control system based on face recognition, which belongs to the technical field of face recognition. Background technique [0002] Since entering the 21st century, my country's economy has developed rapidly, and the living standards of urban and rural residents have been significantly improved, especially the living conditions of urban residents have been continuously improved. When buying a house, security is an important condition for examining whether the property management level is perfect. A house is a home, and it needs absolute security. For office workers, most of the time during the day, they work in the company or go out when they are not at home. The security problem at home has always been very distressing.

Problems solved by technology

A house is a home, and it needs absolute security. For office workers, most of the time during the day, they work in the company or go out when they are not at home. The security problem at home has always been very distressing. In the early days, security windows and security doors were installed to improve security. Residential security, this method is not advisable today when there are a large number of high-tech products

Because of the urgent need for residential security, the later plan was to install a security guard box at the gate of the community, and rely on the memory of the security personnel to identify the owner. This improvement is quite applicable in places with small residential areas, but it also has a disadvantage, that is, It relies entirely on security personnel, with subjective judgments, for example, if the visitor is a beautiful woman, there is a good chance of getting away with it

There are also communities that try to install closed-circuit television monitoring systems at main entrances, parking lots, and around the community. CCTV monitoring can only record whether people enter and leave the community, and provide assistance for the public security department to investigate and collect evidence after accidents, but cannot essentially solve security problems.

In recent years, cases of burglary, robbery and homicide by criminals in residential areas have occurred frequently. Only relying on security measures based on civil air defense can no longer meet people's requirements. It is urgent to develop a system with higher security.
