Access control system and method based on face recognition

Abstract

The invention discloses an access control system and a method based on face recognition. The access control system comprises a first trigger module, a second trigger module, a first image processing module, a second image processing module and a facial feature comparing module, wherein a first image collecting module can collect a wholly-body image of personnel in a first trigger area; a second image collecting module can collect a face image of personnel in a second trigger area, process the whole-body image and correct parameters; compared with all prestored outline information, all prestored face images in a correcting area can be screened out, and the prestored face images are matched and fused with the collected face image; the facial feature comparing module can control an access control system to unlock according to a matching degree of the face image; meanwhile, the access control system can sense that personnel enter and exit through a sensing module, so that advertisements can be broadcasted and interrupted in real time; the access control system disclosed by the invention can quickly and accurately perform image recognition, so that access control system response time delay is reduced, advertisement exchange is accurately achieved, a work efficiency of the access control system is improved, and convenience is brought to property management.

Problems solved by technology

[0002] Residential quarters, schools and office areas are densely populated areas, and their safety has attracted more and more attention. For residential quarters, strangers randomly enter the residents' floors to post advertisements, which not only harass the residents' daily life but also bring a lot of security. Hidden dangers, for schools and office areas, the random entry and exit of strangers will interfere with the normal work of schools and office areas, and more will bring hidden dangers to personal and property safety. In the prior art, there are already IC card identification, Iris recognition technology and face recognition technology, etc., for intelligent security monitoring, IC card identification needs to be carried at any time, and it is easy to be stolen after being lost; for iris recognition technology, infrared lamps and infrared lenses are needed to obtain it for identity The recognized iris image should be kept between 20cm-40cm for the human eye and equipment, and the user interaction effect is not very good. In addition, iris recognition technology relies on optical equipment, and external light has a certain impact; for ordinary face recognition technology, in In densely populated areas, the image data stored in the database of the access control system is very large, and some even reach thousands of images. For the peak period of commuting people, the access control system needs to process the images collected in real time, and then communicate with the database system The image data in the system is searched and matched one by one, which easily leads to a delay in the response time of the access control system, which seriously affects the work efficiency of the access control system. At the same time, the existing access control system database update lags behind, especially in primary and middle schools, where students develop rapidly , the characteristics of the human body change significantly, and if the database is not updated in time, it may easily lead to inaccurate image matching.

[0003] In addition, for visitors, the existing technology generally uses the access control system to call the resident units and visits through the building intercom. However, the current building intercom devices that use ordinary wireless methods for information transmission cause large power consumption and high cost. High and short transmission distance, not only the single access method but also the lack of supervision of visitors, can easily lead to disconnection between visitors and users and property monitoring, resulting in untimely unlocking of access control and unsafe hidden dangers
