本文設計與實現了運用背景差法的一個基于無線網絡的交互的智能監控系統，該系統的基本功能有1）運用背景差的算法檢測并跟蹤行人，并以文件形式保存下圖像，發送該圖像到網絡服務器上，供用戶以Web 形式瀏覽；2）將圖像發送到手機終端；3）實現手機與系統交互。實驗證明，該系統在復雜的場景中具有良好的性能，且實時性滿足要求。
關鍵字：背景差方法，智能監控，行人檢測，行人跟蹤。
【Abstract】 In this paper we design a novel background subtraction techniques to deal with the foreground segmentation, and implement the Wireless Network based intelligent monitor system, the basic functions of which include 3 aspects 1)getting human objects by applying background subtraction techniques, save the image and upload to FTP server; 2) send the image to cell phone; 3)The system can communicate with cell phone by CDMA
model. The experiment results demonstrated that the system can adapt to environment changes in real-time.
【Key words】Background subtraction techniques; Intelligent surveillances; human detection; human track.
