An Adaptive Multi-camera Video Surveillance System Technology
摘要
In an evolution of video-based surveillance, a digital video surveillance system over Internet has gradually substituted for the traditional closed circuit television system. This new digital video surveillance system can provide ubiquitous surveillance services by utilizing existing network infrastructures. In this paper, we propose an adaptive multi-camera video surveillance system called AMCvs, in which three major components are (1) a camera-PC that is responsible for capturing, analyzing and backup videos, (2) a backup server that can keep uploaded backup videos and an information-retrieval server (IRserv) that can provide a video-retrieval service and index videos based on parsed event files, and (3) a client application that contains a friendly user interface, in which users can view his/her preferred historical videos over multi-channels and interact with the Irserv. AMCvs can dynamically adjust monitored video qualities (e.g., a playback frame-rate and a region-of-interesting are quality) using scalable video coding techniques. Besides, the approaches of camera install and calibration are also proposed for built-in multi-camera surveillance environments. In the experiment, the AMCvs system is presented to show its merit and convenience for the well-designed surveillance application.
