远程监控广泛应用于银行、商店、办公室、家庭等场所，在传统的远程监控系统中，为了获取远程现场的图像，一般采用固定或有源的窄视场摄像机。本文提出了一种新的网络监控系统。建议的监控系统，它使用多个全向摄像机和网络，是基于一个服务器/客户端模型：服务器计算机，其中每个连接到一个全向视频摄像机，被放置在监控区域和客户端计算机被放置在用户侧。服务器检测移动物体并从传感器估计它们的方向。客户端根据从服务器接收的对象的方向来估计对象位置，并向用户呈现以对象为中心的透视图像。在实验中，所实现的系统可以做到这些在实时。
Remote surveillance is widely utilized in banks, shops, offices, at home and so on. In most conventional remote surveillance systems, fixed or active cameras with a narrow field of view are generally used in order to acquire an image of the remote site. This paper proposes a new networked surveillance system. The proposed surveillance system, which uses multiple omnidirectional cameras and network, is based on a server/client model: the server computers, each of which is connected to an omnidirectional video camera, are placed in the surveillance area and the client computer is placed on the user side. The servers detect moving objects and estimate their directions from sensors. The client estimates object positions from their directions received from the servers and presents object-centered perspective images to the user. In experiments, the implemented proposed system can do those at real-time.
