Real time monitor system based on dual-camera cooperative fusion

One of the main aims for modern video surveillance is to capture clear imagery of Region of Interest (ROI) in large-scale. However, it is hard to achieve the goal by zooming when the ROI is far from the surveillance system. A station-active dual camera (SADC) system is designed to acquire the detailed and overall information of object at distance. The target can be detected and tracked in the wide Field Of View (FOV) of the static camera, based on the method of modified codebook and Tracking-LearningDetection (TLD) separately. Then the control part of the system calculates the correct position, which directs the Pan-Tilt-Zoom (PTZ) camera to gaze at the target and get a high resolution image of the detected candidate. In the system, some results are obtained in the experiments of indoor and outdoor setting, which is applicable in real time surveillance. From the comparison, it is found that the TLD have an advantage over codebook on robustness to illumination variation and the scene of multi motion objects.
