摘　　要：采用DaVinci技术,设计一种具有人脸检测与跟踪功能的智能监控系统.利用TMS320DM6446芯片的双核结构优势,在ARM端实现基于Linux系统的多线程应用程序,负责视频录放、用户界面控制、视频信号的网络传输、外围器件控制等;而在DSP(数字信号处理)端完成基于AdaBoost的人脸检测、基于卡尔曼滤波器和Mean Shift相结合的人脸跟踪及H.264视频编码.实验结果表明:智能监控系统能实现人脸定位与跟踪,准确、实时性高,而且可由具有面向网络数据传输的客户端程序实行远程监控.An intelligent surveillance system with the features of face detection and tracking based on DaVinci technology is proposed. To exploit the resources of dual-core structure of DM6446, multiple applications, including video recording and playback, user interface control, video signals transmitted over the network, the external device control and so on run in the ARM-side, and those high computational complexity routines, such as AdaBoost-based face detection, face tracking algorithm using Kalman filter combined with Mean-Shift algorithm, and H. 264 video codec, are executed in DSP-side. Experiment results show that the system can meet demand of real-time video monitoring, and it can accurately detect and trace the faces, and the data can be transmitted over the network with the client program for the implementation of remote surveillance.
