Problems solved by technology

[0003] Under the existing video coverage method based on file value rating, it is found that there are two deficiencies: first, when video coverage is performed, it is only covered according to the morning and evening of the time. It is very likely that there are valuable video files in the video files, and there may be worthless video files in the recent video files that have been preserved
This is not conducive to the rational use of the generated video files
Second, when retrieving video files, it may be necessary to traverse the entire storage space to obtain the corresponding file list, which leads to low retrieval efficiency, and long-term high-intensity access to the storage space shortens the life of the storage device

Embodiment Construction

[0011] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0012] Such as figure 1 As shown, the flow chart of the video coverage method based on the file value rating of the present invention is provided, which is realized by the following steps:

[0013] a). Collect video information, use monitoring equipment to collect video information of the scene environment, and form a video file;

[0014] b). Establish a directory of video files. According to the folder names at all levels from top to bottom, they are root directory, custom video folder name, date, and video type, and establish a directory for storing video files in order to save video files. ;

[0015] In this step, according to the folder name from top to bottom, it is named in the form of root directory, custom video folder name, date, and video type, which is beneficial to the search and retrieval of video files.

[0016] c). Naming and saving th...

Abstract

The invention discloses a file value rating-based video coverage method, which comprises the following steps of (a) acquiring video information; (b) establishing a video file directory; (c) naming and storing files; (d) rating the video files according to value estimation indexes; (e) establishing a file rate list; (f) judging whether a memory space is sufficient or not; (g) searching the file directory for the files; (h) searching for the rating information of the files; (i) deleting the files with the lowest value rates; (j) judging whether the memory space from which the files are deleted is sufficient or not; and (k) covering the video files. According to the video coverage method, the video files are rated according to the value estimation indexes when being generated, and the video files with the lowest rates are deleted during file coverage, so that the reserved video files are the most valuable, and the shortcomings of the conventional time-based sequential deletion are overcome.

Description

technical field [0001] The present invention relates to a video overlay method based on file value rating, more specifically, to a video overlay method based on file value rating that can ensure that the remaining video files are the most valuable. Background technique [0002] With the continuous advancement of technology in the security monitoring industry and the innovation of storage hardware, it is possible to store massive video data. In the existing video surveillance system, a central storage method is generally adopted. The recording server records according to the recording plan made in advance for later viewing. However, because the capacity of the storage device is limited, generally only the most recent video is kept, that is, when the capacity is insufficient, the earliest video is overwritten. In addition, when the video needs to be played back, the entire storage space needs to be traversed. How to find video information that meets specific conditions fro...
