摄像头网络在我们社会的许多方面已经变得更加主导。设计主动云台变焦 (PTZ) 摄像机网络需要根据指定的覆盖要求将摄像机适当放置在环境中，并检查网络对环境动态的运行弹性。在物理建立网络之前，此设计过程至关重要，以确保成功部署和运行。在本文中，我们提出了一个可用于在现实虚拟仿真环境中设计实用 PTZ 摄像机网络的框架。该框架能够优化摄像头网络布局，以覆盖监控空间中的特定感兴趣区域 (ROI)。此外，根据环境动态模拟网络操作，以确定对预先建立的设计的影响，因为主动摄像头网络预计会监视环境中发生的其他未知事件。提出了一个监视案例研究，其中结果显示了如何将开发的框架充分用于实验设计和测试主动 PTZ 摄像机网络。
Camera networks have become more predominant in many aspects around our society. Designing active Pan-Tilt-Zoom (PTZ) camera networks requires placing the cameras appropriately in the environment according to the designated coverage requirements as well as examining the network's operational resilience to the environment dynamics. This design process is crucial before physically establishing the network to ensure successful deployment and operation. In this paper, we present a framework that can be applied for designing practical PTZ camera networks in a realistic virtual simulation environment. The framework enables optimizing the camera network placement for coverage of specific regions of interest (ROI) in the monitored space. Also, simulating the network operation against environment dynamics in order to determine the impact on the pre-established design as an active camera network is expected to monitor additional and unknown events happening in the environment. A surveillance case study is presented where results show how the developed framework can be adequately used for experimentally designing and testing active PTZ camera networks.
