本文针对当前企业智能考勤打卡过程中存在佩戴眼镜出现的识别不清问题，采用基于PCA+ICA的人脸识别算法，完成正面戴眼镜人员眼镜的摘除。该系统使用人脸识别相关技术完成图像预处理、正面人脸库的建设、眼镜摘除、人脸重建等过程。通过MATLAB 仿真实验得出，该系统对工作人员面部变化有更强的鲁棒性，识别率准确，改善效果明显。

Aiming at the problem of face recognition with glasses in the enterprise intelligence attendance system, this paper adopts PCA+ICA algorithm, removing the glasses from the staff. The system uses face recognition technology to complete image preprocessing, face database construction, glasses removal, face reconstruction and so on. According to the MATLAB simulation,the system has stronger robustness to the facial changes of the staff, the recognition rate is accurate, and the improvement effect is obvious.
