Problems solved by technology

However, the application field of this method is in video downloading rather than real-time storage, and there is no concept of time. For example, if I want to play a video at 1:00, this patent cannot be applied; and this patent is traversing folders, without indexing, and the speed will be relatively slow

Embodiment Construction

[0030] see Figure 1 to Figure 3 As shown, a kind of massive video data retrieval method of the present invention comprises the following steps:

[0031] Step 1. An index directory structure is established in the video storage system. The index directory structure is divided into two layers of folders. The first layer of folders is named with time, which can be named with year, month, and day, such as January 1, 2014 The folder named 2014010101. The second layer of folders is named after the channel ID; the second layer of folders contains I frame index, video file index and video file; the I frame index includes I frame information; the video file index includes channel ID, recording time period , video file name, channel name and playback device name; the channel ID is used to identify the uniqueness of the playback device.

[0032] Step 2. When the video data is retrieved for a period of time (i.e. when the video data is retrieved), locate the folder on the first layer co...

Abstract

The invention provides a method for searching large volume of video data. The method comprises the following steps that 1, creating an index list structure in a video storing system, wherein the index list structure is divided into two layers of file folders; 2, when video within a period of time is searched in video data, positioning the video to the first layer of file folder of corresponding time according to time, positioning the video to the second layer of file folder of a corresponding channel according to a channel ID (identity) of the video, obtaining a required video file from the second layer of file folder, at a client, listing the video of the channel ID of the video within a searching time interval, and storing the searching result; 3, clicking to play the video of a target time by a user, wherein the video file corresponding to the target time can be directly and quickly positioned according to the searching result. The video file of some second can be quickly positioned, the searching speed is high, and the performance of the system is improved.

Description

Technical field [0001] The invention involves the technical field of big data storage systems conducted in video surveillance in security, especially a method of massive video data retrieval and its system. Background technique [0002] The existing video storage systems all store data to the disk, write information such as video file paths into the database, and then the user retrieves according to the specific time, and selects the time to play back. [0003] If the user wants to quickly and precisely positions it to a second, or if you want to see if there is audio in this time, or to find an event video, the existing storage system only includes the basic information such as video file paths and time, which will not be able to meet the user’s whichThese needs. [0004] In the existing technology, a kind of "monitoring video video traceable method" is public number: 102055946A, and the public date is: 2011-05-11 China Patent.Retanement retrospective method, no complicated inco...
