A Video Surveillance Method Based on Dynamic Image Detection

Abstract

The invention discloses a video monitoring method based on dynamic image detection, which includes the following steps: step S1: wirelessly connect the dynamic image detection system to the image monitoring system of the existing architecture; step S2: the dynamic image detection system Perform dynamic image analysis on the collected image information, store the identified dynamic image and send the dynamic image and its time stamp to the background storage server and / or remote monitoring terminal via the Internet; step S3: the background storage server receives the dynamic image detection system Send the dynamic image, and use the dynamic image and its time stamp to mark the corresponding time point in the stored video surveillance information collected by the first image acquisition module, and preferentially cover unmarked video surveillance information during cyclic storage. Compared with the prior art, since the dynamic image detection system is wirelessly connected to the original image monitoring system, there is no need to change the hardware structure of the original image monitoring system.

Description

technical field [0001] The invention belongs to the field of video monitoring, in particular to a video monitoring method based on dynamic image detection. Background technique [0002] At present, most of the widely used image monitoring systems in the market adopt static image monitoring, regardless of whether there are moving objects in the monitoring area, they are all collected and stored, which requires a large amount of storage space for the system and increases the cost of the system. In order to reduce storage costs, the existing technology usually adopts a circular storage method, that is, the latest video is used to overwrite the older content, but since the earlier video is overwritten, the information contained in it will be lost, and the general monitoring system has a minimum Requirements for effective storage time. With the maturity of high-definition camera technology, high-definition cameras are used more and more widely. The cameras in traditional monitor...

Problems solved by technology

[0002] Most of the image monitoring systems widely used in the market currently use static image monitoring, regardless of whether there are moving objects in the monitoring area, they are collected and stored, which requires a large amount of storage space for the system and increases the cost of the system

In order to reduce storage costs, the existing technology usually adopts a circular storage method, that is, the latest video is used to overwrite the older content, but since the earlier video is overwritten, the information contained in it will be lost, and the general monitoring system has a minimum Effective Storage Time Requirements

With the maturity of high-definition camera technology, high-definition cameras are used more and more widely. The cameras in traditional monitoring systems have been upgraded to high-definition cameras. According to the existing storage technology, the storage space required is getting larger and larger, resulting in the original monitoring system. After upgrading the camera, the effective storage time cannot meet the storage requirements of the user, resulting in the need to upgrade the entire system, resulting in a waste of resources and an increase in cost

In practice, in some applications, such as schools, factories, office buildings, etc., few people appear at night, but the camera is working as usual. The video recorded in this way may have no effect at all. takes up storage space

[0003] At the same time, the static image monitoring adopted in the prior art cannot give early warning of emergencies, and the monitoring video can only be viewed manually in real time or afterwards. Loss
