Networked telepresence and remote surveillance systems using an omnidirectional image sensor

摘要

This paper describes a networked telepresence system and a remote surveillance system using an omnidirectional image sensor. The networked telepresence system transports an acquired omnidirectional video stream of a remote site to an observation site, and then generates a view-dependent perspective video stream at the observation site. The method enables us to instantly look around a visualized space of a dynamic real world through the network. The remote surveillance system is based on a server/client model. The server PC of the surveillance system detects intruders and estimates their directions from a sensor. The client PC determines the correspondence among intruders in the current frame and those in the previous frame from their directions received from the server PC, and presents their perspective images to the user like the telepresence system. The user can also look around a visual space of a surveillance area.
