由於近年來恐怖攻擊事件頻傳，已有許多國家正致力於開發影像監控系統來提高現有監控系統的人力有效性，在過去的相關文獻中，大多針對如何在場景中偵測遺留物與遺失物做相關的研究，而本研究中所發展的自動擷取事件觸發者之臉部資訊的監控系統，不僅能找出遺留物或遺失物事件的遺留物持有者與遺失物擷取者，並記錄事件發生時的關鍵性影像，同時也會擷取該事件觸發行人的較清晰臉部特徵資訊，能與監控方事先建立的危險人臉資料庫做比對，大幅提升影像監控系統的保全性。此系統使用德州儀器(Texas Instrument)之TMS320DM642 DSP為開發平台與雙攝影機架構，由場景攝影機搭配PTZ(Pan, Tilt, Zoom)攝影機，經由場景攝影機所擷取的畫面資訊，可以偵測出場景中的遺留物與遺失物，並經由座標轉換方式將PTZ攝影機引導至事件觸發者的頭部位置，擷取較清晰的臉部特徵資訊。遠端監控人員也可以隨時透過遠端監控介面，了解場景中的特徵狀況，也可以操作遠端監控介面，觀看與控制雙攝影機的場景資訊。如此便能達到智慧型自動擷取遺留物持有者與遺失物擷取者的臉部資訊之監控系統。

Due to the terrorist attacks is frequently in recent years, many countries have been developing video surveillance systems. They are working to improve the effectiveness of human resource on existing surveillance system. Over the past literatures, mostly were researched on how to detect abandoned objects and stolen objects. In this research, we develop a surveillance system to automatically capture information about the target pedestrians’ face. It’s not only to detect the owner of abandoned object and stolen object, but also record the critical event’s image. In addition, the surveillance system can capture the clear face that is who trigger off event, and compare to the dangerous face database. Let's enhance the security of the video surveillance system. Therefore, we will combine TI TMS320DM642 evaluation module with dual-camera module that can detect owner of abandoned object and stolen object. The field camera is responsible for detecting the head reference point of owner of abandoned and stolen object. Via coordinate’s transformation, the PTZ camera can be guided to the target pedestrians’ head zone and capture the facial information. Consequently, the surveillance can monitor the environment remotely via the internet transmission. They can also select for many functions in the user interface. Hence, we develop an intelligent public surveillance system can detect the ownership's face of abandoned object and stolen object.
