Virtual vision and smart camera networks

摄像机网络是一种新兴的使能技术，可用于广泛的应用，包括视频监控、环境和交通监控、老年人护理、智能环境以及城市和参与式传感。然而，考虑到在扩展的公共空间中部署和试验适当复杂性的摄像机网络的成本和其他严重障碍，大多数研究人员受到摄像机网络研究中具有挑战性的开放问题的激励，根本没有资源来研究大规模的物理摄像机网络。另一个引人注目的选择是“虚拟视觉”，这是一种新颖的摄像机网络研究范式，它规定使用视觉和行为逼真的虚拟环境来开发和评估摄像机网络。虚拟视觉使研究人员能够在视觉和行为逼真的3D计算机模拟环境中部署虚拟摄像机网络，并在现实条件下对这些网络进行实验。

Camera networks are an emerging enabling technology for a broad range of applications, including video surveillance, environment and traffic monitoring, elderly care, intelligent environments, and urban and participatory sensing. Most researchers who are motivated by the challenging open problems in camera network research, however, simply do not have the resources to work with a large-scale physical camera network, given the cost and other serious impediments of deploying and experimenting with a camera network of appropriate complexity in an extended public space. A compelling alternative is ``Virtual Vision'', a novel camera network research paradigm that prescribes using visually and behaviorally realistic virtual environments for developing and evaluating camera networks. Virtual vision enables researchers to deploy virtual camera networks in visually and behaviorally realistic 3D computer simulated environments and to experiment with these networks under realistic conditions.
