摘　　要：使用Qt结合OpenCV设计了一款基于嵌入式的无线视频监控系统,该系统具备人脸检测和头像保存功能。系统采用C/S结构,在ARM开发板上搭建的Qt多线程Linux系统服务器用于采集和发送视频;用Qt结合OpenCV制作的客户端运行在PC上,提供监控功能。介绍了Qt的Linux系统环境设置与ARM移植、V4L2视频采集的过程以及如何用Qt多线程处理视频数据。测试结果表明,在Wi Fi环境下,系统可进行有效的实时监控。An embeded wireless video monitoring system with the functions of face detecton and head portraits saving was designed by using Qt coupling with OpenCV in this paper. The system adopted C/S structure. Multi-threaded Linux system server was built with Qt on ARM development board for acquisition and transmission of video data. The client was made with Qt and OpenCV running on the PC, to provide monitoring function. And it also introduced the Linux system environment setting for Qt with Qt transplanting to ARM, the process of V4L2 video acqusition and how to do muhi-threaded video data processing by using Qt. The test results show that under WiFi environment, the system carries out real-time monitoring effectively.
