Abstract

The invention provides a central monitoring system based on a plurality of monitoring cameras and a central monitoring method. The central monitoring system conducts a central monitoring on the image from a plurality of monitoring cameras, which can reduce the monitoring burden on supervisors and reduce the occurring of missing abnormal events. Image processing is conducted based on respective image data of the plurality of monitoring cameras. Motion abnormity of a people can be calculated based on each camera, and display frame rate can be adjusted based on the abnormality. In this case, images from the monitoring cameras with large abnormity can be preferably seen; the monitoring burden on supervisors can be reduced; early discovery on abnormal events can be quickly realized and abnormal events can be quickly dealt with. The monitoring efficiency is improved through emphasizing and displaying the image of the monitoring camera adjacent to one monitoring camera where abnormality occurs or splicing among images.

Description

technical field

[0001] The present invention relates to a centralized monitoring system and a centralized monitoring method for performing wide-area monitoring by a plurality of monitoring cameras. Background technique

[0002] When collectively managing a plurality of surveillance camera images in the central management room, the plurality of surveillance camera images are aligned on one screen and monitored. At this time, monitoring the images of multiple surveillance cameras at the same time is a very boring job for the surveillance staff. In the case of monitoring the images of 25 surveillance cameras at the same time, it is difficult to concentrate after 20 minutes. Furthermore, when monitoring a scene in which the background changes constantly, such as an escalator or a moving passage in a monitoring area, a plurality of screens are constantly changing, and the monitor feels tired just looking at these. In such a situation, when an accident occurs in a plurality of im...
