Local reconfiguration for simultaneous coverage and tracking in a large scale camera network

We present a distributed camera control algorithm that can be used for the monitoring of large regions using a network of PTZ (pan/tilt/zoom) cameras. The proposed strategy would allow for continuous target tracking at a high resolution, while still maintaining coverage over the entire monitored region at the highest possible resolution. Our algorithm requires only a local exchange of information, is quick to converge and ensures longer periods of stability between successive reconfiguration steps. We evaluate the performance of our algorithm in simulation and demonstrate that local reconfiguration is sufficient for maintaining an acceptable coverage of target and non-target points.
