Embodiment Construction

[0040] The technical solution of the invention is to construct a crowd situation monitoring system aimed at identifying abnormal behaviors. Aiming at the movement situation of the crowd in large-scale event venues, the system takes video and audio signals as the object, extracts and analyzes the characteristics of the crowd in the video signal, such as the number, density, and flow direction, and then combines the audio signal and the environmental detection collected by the sensor components Signals, crowd sentiment index, congestion hotspots and other indicators are extracted to represent the crowd situation, and according to the judgment results, a channeling model for the monitored crowd is given to achieve the purpose of crowd status monitoring.

[0041] Such as figure 1 with 2 As shown, in the crowd situation monitoring system of the present invention, it includes a signal acquisition unit, a signal preprocessing unit, a crowd situation analysis center and a client. In...

Abstract

The invention relates to a system and a method for monitoring crowd situation. The system comprises a signal acquisition unit, a signal preprocessing unit, a crowd situation analysis center, a client and a transmission network, wherein the crowd situation analysis center is used for comprehensively analyzing feature extraction results output by the signal preprocessing unit to extract the quantity, the density and the flow direction of the crowd in the region, and obtaining a dredging and managing model of the crowd in the monitoring region according to sentiment indexes and congestion spots obtained by estimation; and the client can be used for displaying monitoring signals, preprocessed results of the signal preprocessing unit and comprehensive analysis results of the crowd situation analysis center, and giving an alarm. The technical scheme of the invention can realize the purpose of early warning the crowd congestion situation of important exits and entrances or square regions, then compute a decision model for dredging and managing the crowd in the monitoring regions, and set flow control schemes for different monitoring regions, thus the crowd situation of large public places can be simultaneously displayed, analyzed, responded and processed in real time.

Description

technical field [0001] The present invention relates to a monitoring system, and more specifically, relates to a crowd situation monitoring system and method. Background technique [0002] In recent years, many large-scale terrorist incidents around the world have occurred in crowded public places. In particular, crowd monitoring at the entrances and exits of large public places, such as squares, streets, and stadiums, has increasingly become an important aspect of public safety management. [0003] Under normal circumstances, individuals in the crowd walk randomly in the square, and at the same time are attracted by the surrounding environment, showing a phenomenon of small-scale gathering. For example, there will be more crowds gathered around important viewing spots and flower beds, but the overall crowd is still relatively loose. And when an abnormal event occurs, the movement of the crowd presents a group effect. When the crowd is in a highly dense state, abnormal ev...
