Problems solved by technology

[0005] Compared with the past, the existing video surveillance system only has certain technological progress in terms of physical storage media and information transmission mode, and the realized functions are still only real-time video viewing and post-event video playback, and cannot realize early warning. , so for the end user, its utility is not maximized

Embodiment Construction

[0042] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0043] like figure 1 As shown, it is a schematic structural diagram of an embodiment of the video surveillance warning system of the present invention. In this embodiment, the video monitoring and warning system mainly consists of three parts: bayonet monitoring unit 1 , comparison server 3 and central management platform 4 .

[0044] The checkpoint monitoring unit 1 is usually located at the checkpoint site to monitor each checkpoint (such as station entrances and exits, airport entrances and exits, etc.). The checkpoint monitoring unit 1 can monitor the preset monitoring area. When the object entering the monitoring area) enters the preset monitoring area, one or more images are taken for the monitoring object, and the imaging effect in the one or more images is selected to meet the requirements (for example, it is ...

Abstract

The invention relates to a video monitoring and warning method, comprising the following steps: when a bayonet monitoring unit detects that a monitored object enters a preset monitoring region, one or more images are shot for the monitored object; the bayonet monitoring unit selects the image with the imaging effect which is in line with the requirements from one or more images to carry out the catch, the optimization and the characteristic extraction of an human face image, the extracted characteristic data is sent to a comparison server, the comparison server calls the characteristic data in a human face characteristic database to be compared with the extracted characteristic data, if the comparison result is consistent, a warning instruction is issued. The invention also relates to a video monitoring and warning system. The video monitoring and warning method and the system adopt the active monitoring, the remote comparison and the warning mode to improve the effectiveness and the activity of the system and reduce the pressure of management staff, thereby being applicable to network video monitoring industry and government safety urban construction and realizing the unified and large-scale people tracking by the mode with more convenience and lower cost.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a video monitoring warning method and system. Background technique [0002] Looking back on the development history of more than 20 years, video surveillance technology has experienced the first generation of analog systems (VCR), to the second generation of semi-digital systems (DVR / NVR), and then to the third generation of fully digital and networked systems (network camera and video server) three stages of development and evolution. Among the existing video surveillance systems, digital and networked video surveillance systems have become the mainstream. [0003] Common video surveillance systems consist of figure 1 As shown, it includes a front-end video unit 1 , a client unit 2 and a central management platform 3 . The front-end video unit 1 installed at the monitoring point is used for functions such as acquisition, buffering, encoding, forwarding, and storage of audio an...
