Building control system based on face identification

Abstract

The invention provides a building control system based on face identification. The building control system based on face identification comprises a video acquisition module used for obtaining video stream, a face detection module used for decoding, frame extraction, and face detection treatment of the video stream so as to obtain face data, a face identification module used for characteristic analysis on face data and obtaining identification results through face identification using a face database, a comprehensive management module used for determining the position of people based on identification results and camera number, an elevator linkage control module used for sending the commands of the comprehensive management module to an elevator, an elevator control module used for controlling calling, elevating, and door opening and closing logic operation of the elevator, an access control linkage control module used for sending the command information of the comprehensive management module to an access control module, and an access control module used for controlling building door opening and closing, building gate machine opening and closing, and visitor call operation. The building control system is used for realizing entrance automatic control through face identification of visitors.

Description

technical field [0001] The invention relates to the technical field of face recognition, in particular to a building control system based on face recognition. Background technique [0002] As the public has higher and higher requirements for the safety of public buildings, in addition to installing access control systems in rental houses, intelligent buildings, computer rooms and other places, people have also installed video surveillance systems to swipe cards and monitor people in and out in real time. Realize detailed records of personnel entry and exit information and video information, reduce security personnel, and carry out intelligent management. Most of the video access control devices currently on the market are composed of access control controllers, video cameras, front-end controllers and remote control centers. The face information collected by the collector is then sent to the server for comparison, and at the same time it is determined whether the electronic...

AI Technical Summary

Problems solved by technology

Due to the huge amount of processing and comparison of face images, especially when there are many pre-stored face images, real-time performance cannot be guaranteed when using microprocessors, and the cost of using computers or servers is too high

Moreover, the existing access control devices based on face recognition rely solely on collected face images for recognition, and there are several relatively large shortcomings: one, there is no preliminary recognition and judgment for users, and the face image collection is directly performed, which increases the Additional identification work for access control devices

Second, if someone else obtains the face image or facial model of the legal person, the authentication can be passed, and the security is low

3. The above-mentioned access control management system has a single function and is inconvenient to use

Especially, if the owner is not at home, it is impossible to monitor which visitors have visited, and it is difficult to meet people's needs
