A security monitoring video storage and playback method

Abstract

The invention provides a security monitoring video storage method; comprising the following steps: taking the ingestion time of each frame of monitoring picture as an element, compiling a one-dimensional time table; establishing an image library for storing monitoring pictures, and first The ingestion moment of the first frame is added to the starting position of the time table, and the first frame of monitoring picture is stored in the image library; and the mapping between the ingestion moment of the first frame of picture and the image data is established; for each frame of monitoring screen, add its capture time to the end of the timetable; compare its image data with the image data corresponding to the previous frame of monitoring screen, and when the difference between the two is within the specified range, discard the image data of the current frame and replace it with The capture moment of the current frame is mapped to the image data corresponding to the previous frame of the monitoring picture; this method can significantly reduce the amount of stored data of the monitoring video.

Description

technical field [0001] The invention relates to the field of electronic security systems, in particular, to a method for storing and replaying security monitoring videos. Background technique [0002] In the field of security monitoring, continuous capture, continuous storage, and continuous playback of monitoring images are widely used. According to this mode, in the case of continuous monitoring, since the total number of frames of the monitoring picture is huge, for the high-definition monitoring picture, the data amount of each frame picture itself is also very large. In this way, the data amount of the monitoring video in a short period of time is It is very huge, which is a great test for the video storage space of the currently popular network cameras. If you need to apply for a network server for monitoring video storage, the cost is very expensive. On the other hand, for the current security surveillance video, if you want to retrieve the playback surveillance vide...

Problems solved by technology

According to this mode, in the case of continuous monitoring, since the total number of frames of the monitoring picture is huge, for the high-definition monitoring picture, the data volume of each frame picture itself is also very large, so the data volume of the monitoring video in a short period of time is only It is very large, which is a great test for the video storage space of the currently popular network cameras. If you need to apply for a network server for monitoring video storage, the cost is very expensive

On the other hand, for the current security monitoring video, if you want to retrieve and playback the monitoring video after a security incident occurs, you can only play the video continuously in a fast-forward manner, and capture occasional incidents in the video. The waiting time is very long. In the case of multi-angle monitoring, multiple videos need to be played back in this way. The workload is very arduous, which is not conducive to quickly solving the case.
