Embodiment Construction

[0024] The technical solutions of the present invention are further described in detail below with reference to the accompanying drawings, but the protection scope of the present invention is not limited to the following.

[0025] like figure 1 As shown, a double-indexed video loop storage and fast retrieval method includes a video image storage step and a fast retrieval step;

[0026] The described video image storage includes the following sub-steps:

[0027] S101, obtain a frame of video data that needs to be saved, determine whether it is I frame data, if so, proceed to step S102, if not, end the operation;

[0028] S102, storing video data;

[0029] S103. Check whether the space of the current storage path is sufficient, if so, create a file, determine whether it is stored in the current path or another path according to the current storage path, and create a video file and a video index file at the same time, if not, delete the oldest file cyclically video files;

Abstract

The invention discloses a double-index video circulating memory and quick retrieval method. The double-index video circulating memory and quick retrieval method comprises a video image storage method and a quick retrieval method, wherein the video image storage method comprises the following steps: judging whether the video data to be stored are I-frame data, conducting storage of the video data, checking the current storage path volume, meanwhile creating a video file and a video index file, and conducting multipath disk management to add the file path indexes to a database; the quick retrieval method comprises the following steps: calculating the name of the video file according to time through the database indexes, directly retrieving the storage position of the files in the database, accurately locating the deviation position of specific point in time in the files according to the file indexes, and directly obtaining the video data from the time point to play. The double-index video circulating memory and quick retrieval method disclosed by the invention has the benefits that the video is stored and retrieved through the double indexes to greatly shorten the retrieval time, increase the storage reliability and reduce the clip files.

Description

technical field [0001] The invention relates to an image storage technology in the computer field, in particular to a double index video loop storage and fast retrieval method. Background technique [0002] In the prior art image storage, there are generally two types of video files, one is to store in a fixed size manner, and the other is to store in a fixed time manner. [0003] Traditional video storage is based on a fixed size. Generally, the files are divided into small files for storage, which will generate a huge number of files. Index retrieval through the database during retrieval will take a long time, especially on embedded devices. [0004] If it is stored at a fixed time, the amount of data in the database is small, but it will take a long time to locate the specific time point of the file. [0005] The storage and retrieval methods of these two methods have slow retrieval times when the recording time is long, especially in embedded devices, the retrieval spe...
