Camera pan/tilt control with multiple trackers

In this paper, we consider the multi-camera tracking and the camera active control (pan and tilt). Auction mechanism from economics is developed to choose the best available camera. By modeling the camera bids with prior knowledge of the camera homographies, the system can “think” ahead to perform necessary panning or tilting operations. The uncertainties of homographies are considered inherently in the metrics used for computing camera bids. Further, to have a better tracking result, we use multiple trackers simultaneously. The trackers are rectified periodically based on the previous auction results. The proposed approach is evaluated in a real-world camera network.
