Video-cloud-based early warning method and system of public security threat of urban region

Abstract

The invention provides a video-cloud-based early warning method and system of public security threat of an urban region. A video stream converges to a cloud server by a video cloud technology and is analyzed intelligently to obtain a processing result; the processing result is compared with a video pattern base and a semantic pattern base to obtain comparison results; when the comparison results reaches an early warning condition, early warning information is generated; a time stamp, position information, and the early warning information are overlapped; and then the early warning information is distributed to complete early warning. Therefore, an emergency response speed is accelerated; the public can obtain information of occurrence of incoming potential security threat timely and thus losses caused by sudden occurrence of disasters can be reduced.

Description

technical field [0001] The invention relates to the field of smart city public safety emergency management system construction, in particular to a video cloud-based method and system for early warning of public safety threats in urban areas. Background technique [0002] Under the traditional public security system in urban areas, surveillance cameras all over important targets guard the city day and night. However, the current urban regional public security system has the following problems: [0003] When a security incident occurs, the police must consult the video footage of the surveillance cameras at the incident site and its surroundings in order to obtain complete video information related to the security incident; There is a lack of linkage and visual perception capabilities between them, and it is impossible to use the surveillance cameras at the incident site and surrounding areas for early warning, so it is difficult to lock the suspicious targets exposed in fron...

AI Technical Summary

Problems solved by technology

[0003] When a security incident occurs, the police must review the video footage of the surveillance cameras at the incident site and its surroundings in order to obtain complete video information related to the security incident; There is a lack of linkage and visual perception capabilities between them, and it is impossible to use the surveillance cameras at the incident site and surrounding areas for early warning, making it difficult to identify suspicious targets exposed in front of various surveillance cameras at the incident site and surrounding areas before the security incident occurs, and provide early warning

[0004] When the security incident occurred, the information of the surveillance cameras in and around the incident site was stored on the local recording equipment, which could not be read by the emergency offices of governments at all levels in time. , can’t hear, can’t make it through” passive position, unable to deal with security incidents urgently, directly leading to dereliction of duty by leaders in some areas
