摘要:

针对PC 平台体积大、功耗多、成本高和便携性差的问题, 设计了基于面部特征的嵌入式安全认证终端。选用ARM11 开发板作为硬件平台, Linux 操作系统作为软件平台, 并在平台上移植了Qt 图像化界面库和Opencv 计算机视觉库。人脸检测由AdaBoost 算法实现, 人脸识别由PCA(Principal Component Analysis)算法实现。测试结果表明, 该终端能实现人脸识别的功能, 并且识别精度较高, 时间较短, 达到预期目标。

Abstract:

According to the problems exist in the PC platform of large volume, high-power, high cost and poor portability, the author design an embedded terminal for secure authentication based on facial features. I choose ARM11 development board as the hardware platform, Linux operating system as the software platform, and use transplant Qt graphical interface library and Opencv computer vision library on the platform. Face detection was achieved by AdaBoost algorithm, face recognition was achieved by PCA ( Principal Component Analysis) algorithm. The test results show that this terminal can realize the function of face recognition, recognition accuracy is high and recognition time is short, the desired goal is achieved.

Key words: secure authentication, embedded terminal, ARM11 development board, Linux operating system, face detection, face recognition
