基于OpenCV的嵌入式智能门禁系统设计

Open CV-based design of embedded intelligent access control system

基于智能家居安防系统中安全性的需求,以三星S3C6410嵌入式核心芯片为平台,以Open CV技术为核心,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。将授权人的人脸信息与采集到的人脸信息进行比对,判定门禁系统是否开放。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。本设计已成功应用于智能家居安防系统中。

Smart Home Security System based on security requirements to Samsung S3C6410 embedded core chip as a platform to Open CV technology as the core, designed and implemented with face recognition features intelligent security access control system. The intelligent access control system will first donor＇s human face Gray, dimensionality reduction and eigenvalue calculations and other processing, and then prepare training to be authorized in the relevant information. Then the camera to capture the information processing of the human face. The donor＇s human face to face with the collected information for comparison to determine whether the open access system. After testing, the intelligent access control system completed a face recognition function better, to achieve the access control system design requirements. The design has been successfully applied to smart home security system.
