为了快速有效地验证身份，控制大门的开关，以人脸作为判决因子，判断来访者的合法性，以此来控制门的开关。当红外传感器探测到有人来访时，触发系统抓拍来者的人脸图像，利用OpenCV的人脸检测分类器，快速地进行人脸定位，采用改进的主成分分析算法，实现人脸的识别，与库中存放的合法进入者人脸进行比对；对于允许进入的来访者，控制打开大门，对于不能进入的来访者，系统发出语音提示。经过实验，验证了系统方案的可行性，实现了以人脸为身份识别的智能门控。系统工作稳定，在3 s之内完成工作，识别率达85％。

In order to quickly and effectively control the door ,the human face is taken as a factor to determine the legality of visitors .When the infrared sensor detects a visitor ,the trigger system captures the face image ,the face detection classifier of OpenCV is employed to position the face rapidly .Then the improved algorithm is adopted to recognize the face .Finally ,compared with the stored face images ,the entrance guard system opens the door for the allowed visitor or sends voice prompt for the others .The system is confirmed by experiment .It is shown that the system can realize intelligent access control by identification of the face characteristics .The system is stable and finishes the work in 3 seconds .The recognition rate reachs up to 85% .
