基于OpenCV视觉库和树莓派的人脸识别门禁系统

基于门禁系统中安全性的需求,以OpenCV视觉库为核心,树莓派为硬件基础设计实现了具有人脸识别功能的智能安防门禁系统。本智能门禁系统首先将授权人的人脸信息进行灰度化、降维及计算特征值等处理,再进行准备训练,得到授权人的相关信息。然后对摄像头采集到的人脸信息进行处理。经过测试,该智能门禁系统较好的完成了人脸识别功能,实现了门禁系统的设计要求。

Based on the security requirements of the access control system,with the OpenCV visual library as the core,the Raspberry Pi designed the intelligent security access control system with face recognition function.The intelligent access control system first performs grayscale,dimensionality reduction,and calculation of feature values on the face information of the authorized person,and then performs preparatory training to obtain relevant information of the authorized person.Then the face information collected by the camera is processed.After testing,the intelligent access control system has completed the face recognition function and realized the design requirements of the access control system.
