Security and protection monitoring video storage and playback methods for improving criminal case solving efficiency

Abstract

The invention provides security and protection monitoring video storage and playback methods for improving the criminal case solving efficiency. The storage method comprises the following steps that a one-dimension timetable is edited by taking the shooting moments of all monitoring picture frames as elements; an image library for storing monitoring pictures is established, the shooting moment of the first monitoring picture frame is added to the starting position of the timetable, and the first monitoring picture frame is stored in the image library; mapping between the shooting moment of the first picture frame and image data is established; the shooting moment of each monitoring picture frame is added to the tail of the timetable; and image data of each monitoring picture frame is compared with image data corresponding to the previous monitoring picture frame, if the difference between the image data of the two monitoring picture frames is in a specified range, the image data of the current frame is abandoned, and the shooting moment of the current frame is mapped to the image data corresponding to the previous monitoring picture frame. According to the method, the storage data volume of a monitoring video can be significantly decreased.

Description

technical field [0001] The invention relates to the field of electronic security systems, in particular to a storage and playback method for security surveillance video. Background technique [0002] In the field of security monitoring, the continuous ingestion, continuous storage, and continuous playback modes of monitoring images are widely used at present. 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 it is necessary 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 pla...

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.
