由於恐怖事件在世界各地持續的發生,近年來監控系統越來越被重視,但傳統的監控系統只有錄影與監控的功能,監控人員無法確切的知道場景中的可疑的物件或是發生事件時沒有發出警訊,因此本論文使用德州儀器(Texas Instrument)的數位訊號處理器TMS320DM642 DSP為開發平台,搭配雙組雙攝影機架構來組成一套智慧型公共安全監控系統。在雙攝影機架構下,其中場景攝影機主要用來偵測場景中的行人與遺留物或遺失物事件的發生,當場景中有發生事件時,PTZ (Pan/Tilt/Zoom)攝影機會擷取事件的關係人臉部影像,而本系統是使用雙組系統的架構,會利用此特性來針對場景中的事件關係人進行位置的追蹤,透過三維座標的公式可以計算出事件關係人的景深距離,如此一來就可以知道事件關係人在場景中的移動方向。最後本系統有開發一套使用者人機介面供監控人員作使用,透過使用者人機介面就可以看到雙組雙攝影機的即時影像以及發生事件時的相關影像,以實現具有遠端監控功能的雙攝影機組的智慧型公共安全監控系統。
In recently years, monitoring system is more and more attention. Because terrorist attacks continue to occur around the world. But traditional monitoring systems only have Monitoring and video recording capabilities. Supervisors cannot accurately know a suspicious object in the scene or do not warn when an event occurs. In this paper, we use TI (Texas Instrument) digital signal processing TMS320DM642 development platform with two dual-cameras structure consisting of an intelligent public security surveillance system. In dual camera architecture, the field camera is used to detect pedestrians and abandoned or stolen events. PTZ camera will capture events related facial image when an event occurs in the scene. This system uses two dual-cameras system architecture. So we use this feature to track pedestrians in the scene. Through the three-dimensional coordinates of the formula can calculate depth distance for pedestrians. So we can know pedestrians movement direction in the scene. Finally, we have to develop a human interface for supervisors to use. Through human interface can see two dual-camera system real time image and related images when the event occurred. Thus, we achieve intelligent public security surveillance system with two dual-cameras.
