Problems solved by technology

[0003] In order to solve the problem that the existing surveillance video files are not stored for a long time due to the limitation of storage space (hard disk capacity), the purpose of the present invention is to provide a method for processing surveillance video files, which can be stored in a limited storage space in a more reasonable way. Extend the storage time of surveillance video files, and also provide new technical means for improving the image resolution of surveillance video files

Embodiment Construction

[0018] refer to figure 1 , the monitoring video file format in this embodiment is AVI (or moving JPG) format, there is no distinction between key frame and non-key frame in the video file structure of this format, and each video frame can be decoded separately complete picture, For example A1, A2, A3, A4, A5, A6, A7, A8, A9, A10...An video frame.

[0019] Surveillance video files are stored in local hard disks, memory cards or network disks (hard disks, CDs, tapes and other storage media on the network), and generally have a storage period set. Surveillance video files exceeding the storage period will be deleted to free up storage space for new surveillance video files.

[0020] refer to figure 2 , image 3 , a method for processing surveillance video files in the present invention is: the original surveillance video files (such as figure 1 Surveillance video file in the embodiment) is processed, evenly deletes half of the video frames in the surveillance video file acco...

Abstract

The invention discloses a monitoring video file processing method, relating to the monitoring video file management and storage. The monitoring video file processing method comprises steps of performing frame deletion on an original monitoring video file which achieves the preset storage life limit and is ready to be deleted, uniformly deleting half or more than half of the video frames of the monitoring video files according to the identical interval, generating a new second generation monitoring video file to store after frame deletion is finished, deleting the original monitoring video file, deleting the second generation monitoring video file after the preset second generation monitoring video file storage life limit is achieved, or utilizing the same processing method to generate the third generation, the fourth generation, and N generation monitoring video file. The invention is fast in processing the monitoring video file and is not high in hardware requirement. The beneficial effects of the invention are that: the volume of the monitoring video file is reasonably reduced with the time passing by, and the storage life of the monitoring video file is prolonged.

Description

technical field [0001] The invention relates to a processing method of video files, in particular to a processing method of monitoring video files. Background technique [0002] With the development of electronic technology and network technology, video surveillance has penetrated into all aspects of social management and has become an indispensable tool for maintaining social order. The common application places of video surveillance are: banks, roads, government agencies, rental houses, airports, stations, docks and other densely populated areas, public security prevention and control and sensitive areas. It can be said that in many cities, as long as people leave their homes, they will be photographed by surveillance cameras. In addition, many households are now equipped with surveillance cameras connected to the Internet, and many cars are also equipped with driving recorders to record and archive images. Surveillance cameras generate a huge amount of video data every ...
