本文设计与实现了运用背景差法的一个基于无线网络的交互的智能监控系统,该系统的基本功能有1)运用背景差的算法检测并跟踪行人,并以文件形式保存下图像,发送该图像到网络服务器上,供用户以Web形式浏览;2)将图像发送到手机终端;3)实现手机与系统交互。实验证明,该系统在复杂的场景中具有良好的性能,且实时性满足要求。 This paper designs and implements a wireless intelligent monitoring system based on wireless network using background subtraction. The basic functions of this system are: 1) Detect and track pedestrians with poor background algorithm, and save the image as a file, and send the image To the web server, for users to browse the Web form; 2) the image sent to the mobile terminal; 3) to achieve mobile phone and system interaction. Experiments show that the system has good performance in complex scenes, and real-time to meet the requirements.
