Description
Technical Field
The invention relates to a video storage and backup method thereof, in particular to a high-efficiency low-capacity video storage and backup method thereof.
Background
With the rapid development of society, the safety awareness of people is increasing day by day, more and more companies, banks, communities, schools, hospitals and the like adopt a video monitoring mode to monitor a core area in real time, so that a large number of monitoring videos are generated, the storage and backup problems of the videos are increasing day by day, and the videos which need to be stored and backed up are increasing day by day as the number of the monitoring videos is increasing day by day. Particularly, the storage requirement of videos is increased day by day due to the fact that the videos need to be stored for a long time in the industries of banks, transportation and the like, and the problem that how to solve the storage and backup of the videos with high efficiency and low capacity is a problem to be solved urgently.
In order to solve the above problems, people are always seeking an ideal technical solution.
Disclosure of Invention
The invention aims to overcome the defects of the prior art, and provides a video storage and backup method thereof, which has the advantages of scientific design, strong practicability, small occupied space and strong storage purpose.
In order to achieve the purpose, the invention adopts the technical scheme that: a video storage and backup method thereof comprises the following steps:
step 1, denoising and filtering an original video, and storing the processed original video;
step 2, analyzing the frame-by-frame pictures of the stored video to determine the most frames of pictures;
step 3, video copying is carried out, the copied video is deleted, and deletion delay is set;
step 4, comparing the original video with the most frames of pictures, deleting the frames of pictures if the subsequent frames of pictures in the original video are the same as the most frames of pictures, and saving the frames of pictures if the subsequent frames of pictures in the original video are different from the most frames of pictures;
and 5, when the time of the most frames of pictures exceeds the deletion delay, repeating the step 4 until the video backup is finished.
Based on the above, the video is captured frame by frame in step 2, and then the captured pictures are compared one by one, so as to determine the most frames of pictures.
Based on the above, the most frame of picture is a monitoring video feature picture.
Based on the above, after the video backup is completed in the step 5, the backup video is compressed.
Compared with the prior art, the invention has outstanding substantive characteristics and remarkable progress, and specifically, the invention is different from the traditional direct storage mode, and filters sound to reduce the size of the video through the noise reduction processing of the video, thereby reducing the storage capacity; during further backup, effective pictures are stored through comparison, so that the requirement on backup capacity is greatly reduced; the storage system has the advantages of scientific design, strong practicability, small occupied space and strong storage purpose.
Detailed Description
The technical solution of the present invention is further described in detail by the following embodiments.
The invention provides a video storage and backup method thereof, which are used for storing and backing up various monitoring videos at low capacity so as to reduce the pressure of video storage. The method specifically comprises the following steps:
step 1, denoising and filtering an original video, and storing the processed original video; the original video is subjected to noise processing or the like by using techniques such as noise reduction or the like to reduce the video size, and then stored.
Step 2, analyzing the frame-by-frame pictures of the stored video to determine the most frames of pictures; the most frame picture can be the first frame picture, and can also be the picture appearing most times in the video, and the most frame picture is selected according to the needs aiming at different monitoring videos.
Step 3, video copying is carried out, the copied video is deleted, and deletion delay is set; the video needing to be backed up does not need to be backed up completely, and deletion delay is set according to the requirement so as to ensure the integrity of effective pictures.
Step 4, comparing the original video with the most frames of pictures, deleting the frames of pictures if the subsequent frames of pictures in the original video are the same as the most frames of pictures, and saving the frames of pictures if the subsequent frames of pictures in the original video are different from the most frames of pictures; and a great amount of deletion is carried out on the pictures with the most frames through comparison, so that the storage of effective pictures is ensured.
Step 5, when the time of the most frames of pictures exceeds the deletion delay, repeating the step 4 until the video backup is completed; by adopting the method, the problem of deleting the picture when the maximum frame of picture occurs at each time is prevented, so that the problem of deleting the effective picture is avoided, and further the comprehensiveness of the effective video is ensured.
Therefore, the storage and backup of the whole video are completed, the comprehensiveness of video storage is guaranteed, the storage capacity is reduced, and the utilization rate of the storage space is improved.
In order to ensure the accuracy of the selected most frames of pictures, the video is captured frame by frame in the step 2, and then the captured pictures are compared one by one, so that the most frames of pictures are determined. The most frame pictures adopt different pictures for different industries, such as: and for the floors, the pictures of five persons in the corridor are taken as the pictures with the most frames.
In order to ensure the comprehensiveness of monitoring, the most frames of pictures are monitoring video characteristic pictures, and are properly selected according to different fields. And meanwhile, in order to further compress the storage space, after the video backup is completed in the step 5, the backup video is compressed.
Finally, it should be noted that the above examples are only used to illustrate the technical solutions of the present invention and not to limit the same; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
