VISUALIZATION OF PREDICTED CROWD BEHAVIOR FOR SURVEILLANCE

摘要

Technologies are described for visualization of current and predicted crowd behavior information for surveillance. In surveillance systems, a variety of image capture devices and audio capture devices may be positioned strategically throughout a building or an area. The capture devices may transmit respective audio and video signals to a display device, such as a monitor in a surveillance control room, and to a signal processor for crowd behavior analysis. A signal processor, according to some examples, may- receive crowd characteristics for an -area, derive current crowd behavior information from the crowd characteristics, and predict crowd behavior information based on crowd characteristics, area characteristics, normalised crowd behavior information (from other areas), and/or external information. The signal processor may provide current and predicted crowd behavior information to a display device. The display device may overlay a corresponding video signal with a visualization of the current and predicted crowd behavior information.
