摘要
A distributed system for traffic monitoring and event detection includes a plurality of video units within viewing distance of a thoroughfare to be monitored. Each video unit processes a video stream while monitoring events at the thoroughfare, identifies and analyzes events, encodes traffic meta data characterizing the analysis, and transmits the meta data to a central controller. The central controller stores a geographic map representing the thoroughfare, correlates the meta data received from the video units, and forms a composite representation of the geographic map and the correlated meta data. The central controller replays previously stored composite representations of the geographic map and the correlated meta data, which were monitored under mutually different event conditions. The central controller is also configured to allow changes to previously stored composite representations of the geographic map and to the correlated meta data for the purpose of understanding the impact of change.
