Disclosed is an integrated multi-view surveillance system which integrates multiple surveillance camera images of an area into a large-coverage image of the area in order to monitor the area. The system includes a first camera, a second camera, a third camera, an image processing device, and a display device. The image processing device includes a first defining component, a first synthesis component, a second defining component, an adjusting component, a transforming component, a third defining component, and a second synthesis component.

A conventional surveillance system uses multiple screens to separately display the acquired video streams. It may cause trouble to keep track of the moving targets due to the lack of spatial relationship among the camera views. This paper presents a surveillance system that can integrate multiple video contents into one single comprehensive view. To visualize the monitored area, the proposed system uses planar patches to approximate the 3-D model of the monitored environment and displays the video contents of cameras by applying dynamic texture mapping on the model. Therefore, this system can provide an efficient and practical way for interactive 3-D monitoring of the environment without complicated camera calibration and 3-D model reconstruction procedures. Moreover, the moving objects are extracted through foreground segmentation and then visualized through axis-aligned billboarding. In this way, the proposed system can provide security guards a better situational awareness of the monitored area, including the activities of the tracking targets.
