A systems level approach to perimeter protection

摘要

Effective perimeter protection mechanisms for industrial sites and critical infrastructure must contend with a large variety of potential threats as well as with the fact that normal site activity can be both complex and diverse. This paper documents the development of a system level approach capable of functioning under such challenging conditions. A multi-view tracking system is used to provide real-time site wide trajectories of all observed individuals. A Radar-based system is also used for tracking if and when camera coverage of various regions is not available. Track information is then analyzed with respect to articulated motion analysis, complex event analysis and normalcy analysis. In addition, object recognition is used to classify left behind objects using high resolution PTZ imagery. A real-time integrated version of this comprehensive approach to perimeter protection was deployed using a single standard off-the-shelf desktop computer.
