Abstract:
In this paper, we propose a novel approach to manage an active resources for a centralized active vision system assisted by a wide field of view fixed cameras (WFOV-FC). Indeed, since the WFOV-FC can provide only large coverage with low resolution, these later are used to generate spatiotemporal observation requests from all detected and tracked target in the surveillance zone. The information gathered will be used to schedule the set of active Pan-Tilt-Zoom cameras (PTZ-AC) in order to collect high-resolution videos suitable for further biometric analysis. Based on the output of this biometric analysis, the same used set of active cameras is requested to maximize at the same time the coverage with close-up views of every target identified as a threat. We formulate PTZ multi-cameras assignment and handoff as a planning problem whose solution achieves optimal cameras assignment in real time. Simulation results, show the efficiency of the proposed policy in satisfying both objectives at the same time
