Real-Time Servo Visual Tracking of Digital Video Recorder Security Systems

本文針對數位影像記錄安全系統之即時伺服影像追蹤提出一簡單有效的方法。數位影像記錄安全系統爲克服傳統類比安全系統之缺點，必須具備影像偵測、安全警報、網路通訊、與即時伺服追蹤等功能。本文首先提出以適應性臨界值爲基礎的影像偵測方法克服環境亮度的變化，並標示影像邊界框，以迭代法來區分多個移動物體，接著利用區域分割與線性移動法以節約複雜計算時問而完成即時影像追蹤功能。最後本文以一多個移動物體之影像偵測與即時伺服追蹤實驗，驗證本系統之優點與有效性。

A simple but effective algorithm of real-time servo visual tracking for a digital video recorder security system (DVRSS) is proposed. The DVRSS, which overcomes the drawbacks of a traditional analog video-based security system, provides functions of object detecting, security alarming, network communication, and real-time servo tracking. An object detecting algorithm based on adaptive thresholding to surmount the effect of light level variation is presented. Additionally, an iterative method is introduced to distinguish multiple moving objects by marking the image with bounding-boxes. A motion tracking algorithm based on region division as well as linear translation is used to cope with the computation-intensive problem and complete real-time operation. Finally, an experiment involving detecting and real-time servo tracking of multiple moving objects is presented to illustrate the outstanding merits and effectiveness of the DVRSS.
