Problems solved by technology

[0005] Network video encoder is a professional network transmission equipment for compressing and processing audio and video data. Its advantage is that it does not require a PC on site, and can directly encode and compress analog video signals and send them to the remote monitoring center through the network and accept the control of the monitoring center. signal to realize digital communication with two-way transmission. The development and application of this system is an important step in networked digital video surveillance (such as the "Global Eye" launched by China Telecom, which realizes digital network monitoring through the Internet), but the development of applications puts forward higher requirements. The requirements of this type of system also show the shortcomings of this type of system: ①Networking capability: each node, as a communication node of a digital video network, can only communicate point-to-point with the monitoring center, and authorized customers cannot directly access and visit Even if the monitoring network can be accessed through the Internet, it must pass through the private network provided by the service provider (such as China Telecom's "Global Eye" platform)
This does not enable real-time alarms at the same time as the incident occurs, and thus cannot effectively contain the occurrence of vicious incidents
Moreover, the transmission and storage of a large amount of useless video data not only causes a serious waste of bandwidth and storage resources, but also submerges a small amount of useful information, making it difficult to obtain useful information.

Abstract

The invention belongs to the technical field of monitoring systems, and particularly relates to a distributed network visual monitoring system. A frame difference image processing module is used for performing image foreground segmentation on an image picked up by a monitoring terminal, forming a foreground image, performing inter-frame RGB spatial similarity processing and inter-frame foreground pixel area difference processing on the foreground image, forming frame difference image processing data by statistical data of inter-frame RGB spatial similarity and statistical data of foreground pixel area difference data, and analyzing and processing the frame difference image processing data and a frame difference image threshold to form a motion target detection result. Through adoption of the distributed network visual monitoring system, the key problem of how to enhance the real-time performance of an embedded visual system while ensuring the recognition and tracking efficiency in the prior art is solved. The distributed network visual monitoring system has the beneficial technical effects of enhancing the capability of video monitoring on the aspects of finding abnormal behaviors in real time and transmitting alarm information immediately, greatly lowering the labor cost, generating good economical and social benefits, and increasing the efficiency of security and protection monitoring.

Description

technical field [0001] The invention belongs to the technical field of monitoring systems, in particular to a distributed network visual monitoring system. Background technique [0002] The first type: PC-based video surveillance system: [0003] The PC uses the video capture card to collect the video signal of the camera, and sends the video image remotely through the local area network. The advantage of this system is that the software and hardware resources are abundant, and the networking is simple. High, practicality is greatly limited. [0004] The second type: video surveillance system based on network video encoder: [0005] Network video encoder is a professional network transmission equipment for compressing and processing audio and video data. Its advantage is that it does not require a PC on site, and can directly encode and compress analog video signals and send them to the remote monitoring center through the network and accept the control of the monitoring c...
