摘　　要：随着生物特征技术应用的日趋广泛,市场对门禁的安全性和可靠性的要求也越来越高。文章提出一种基于实时嵌入式操作系统DSP/BIOS和人脸识别门禁系统的实现方法,介绍了系统的整体设计方案以及基于TMS320DM642的门禁系统的硬件设计和软件设计。系统通过摄像头获取人脸图像,用DSP完成人脸特征的提取和识别,通过串口与外部进行通信,达到了成本低、速度快、可靠性高的目的。With the wider application of biometric identification technology, the demand for safety and reliability of access control system becomes higher and higher in market. The realization method of an access control system based on real-time embedded operating system DSP/BIOS and face recognition is put forward, its overall design as well as TMS320DM642-based hardware and software design is introduced. Using camera to acquire face images, DSP to complete the extraction and recognition of facial features, serial port to communicate with outside, the system achieves the target of low cost, high speed and reliability.
