Embodiment Construction

[0023] A preferred embodiment of the present invention will be described below with reference to the accompanying drawings.

[0024] like figure 1 As shown, the monitoring system includes a data acquisition device, a preprocessing device, an analysis device, an alarm device and a human-computer interaction device.

[0025] The data acquisition device includes a camera device and an automatic image recognition device. The camera device is used to shoot pedestrians and fixed objects, and the captured images are sent to the automatic image recognition device. The automatic image recognition device dynamically divides frames according to requirements to accurately identify pedestrians. and fixed objects, and then use the method of image projection and coordinate change to accurately identify the two-dimensional plane position information of pedestrians and fixed objects.

[0026] The preprocessing device is used to calculate the pedestrian's speed v on the basis of the two-dimens...

Abstract

The invention discloses a social-force-model-based monitoring system, which comprises a data acquisition device and a preprocessing device, wherein the data acquisition device is used for shooting and identifying the two-dimensional plane position information of pedestrians and fixed objects; and the preprocessing device is used for computing behavioral characteristic values of the pedestrians and rejecting abnormal data. The monitoring system further comprises an analysis device, an alarming device and a human-computer interaction device, wherein the analysis device is used for calibrating contact repelling force strength and contact friction force strength and comparing the contact repelling force strength and the contact friction force strength with preset contact repelling force strength and preset contact friction force strength to determine whether to output an alarming signal or not; the alarming device is used for giving an alarm according to the alarming signal; and the human-computer interaction device is used for interaction between the monitoring system and a worker. The system combines video monitoring and computer mode identification effectively based on a social force model, monitors collective behaviors with simple operations, and maximally solves social security problems caused by abnormal collective behaviors.

Description

technical field [0001] The invention relates to a monitoring system based on a social force model. Background technique [0002] With the rapid increase of the population and the strengthening of social security awareness, in order to effectively avoid the impact and injury of abnormal cluster behaviors (such as the occurrence of sudden abnormal events) on social security and personal safety, the current monitoring system mainly uses video surveillance and Artificial recognition to monitor abnormal cluster behavior has been widely used in key occasions of cluster behavior such as intersections and buildings. However, this monitoring system obviously requires the staff to stare at the display with their eyes all the time, which is very harmful to the health of the staff (especially the eyes), and often causes omission of abnormal phenomena due to the momentary negligence of the staff. Contents of the invention [0003] An object of the present invention is to provide a mon...
