Video monitoring system and method for detecting moving target of image thereof

Abstract

The invention relates to a video monitoring system and a method for detecting a moving target of an image of the video monitoring system. The video monitoring system comprises a video terminal, a motion detection module and a server terminal. The video terminal acquires and digitalizes a current frame image of a video via a video acquisition module to generate a compressed video stream; the motion detection module is connected with the video acquisition module and used for receiving the compressed video stream and performing a moving target detection pre-treatment, obtaining a motion vector directly from the compressed video stream, and identifying the current frame image which may comprise the moving target by a judgment on the motion vector; and the server terminal is connected with the motion detection module via a network, and used for receiving the compressed video stream subject to the moving target detection pre-treatment, and performing moving target detection on the current frame image which may comprise the moving target to confirm the moving target appears in the current frame image. The system and the method disclosed by the invention have high robustness and high speed, and can precisely detect the moving target.

Description

technical field [0001] The invention relates to an IP monitoring system, in particular to a video monitoring system and a method for detecting a moving object in an image thereof. Background technique [0002] With the popularity of video surveillance systems, motion detection technology has been used more and more. The video motion detection camera cleverly combines alarm and monitoring. In addition to image monitoring through a TV or monitor, it also uses an embedded intelligent analysis module to intelligently analyze the monitored video signal. Once it detects a change in the content of the screen, it will send out an alarm or prompt sound. Please note that at the same time, it can also output linkage signals to trigger the work of related equipment such as video recorders. [0003] At present, most of the intelligent analysis modules in the video surveillance system are located on the server platform to meet the real-time algorithm processing. The server receives the ...

Problems solved by technology

[0003] At present, most of the intelligent analysis modules in the video surveillance system are located on the server platform to meet the real-time algorithm processing. The server receives the video signals transmitted by each camera terminal through the network. Due to the limitation of transmission bandwidth, these multimedia data are stored and transmitted in compressed form. Therefore, when processing, it must be decompressed first, and then intelligently analyzed. The huge calculation makes the number of terminals that can be supported by each server often very limited
