Problems solved by technology

DVR combines video control and video storage, which makes the system more integrated and applicable, but it can only store data on the entire disk of the machine, which limits the scale of system data. Now it has developed into a NVR with network forwarding function, NVR not only has the functions of receiving IPC data, video codec, storage, real-time display and other functions owned by DVR, but also can forward the video data stored locally to other storage systems through the network

Abstract

The invention provides a monitoring video storage method and system. The storage method comprises the following steps: receiving request information for storing a monitoring video, wherein the requestinformation carries the monitoring video and a plurality of identifier information of the monitoring video; respectively setting the monitoring video and a storage path of a key frame in the monitoring video, and combining all identifier information of the monitoring video to save metadata as each subdata in the metadata of the monitoring video; saving the monitoring video according to the storage path of the monitoring video recorded in the metadata; and extracting the key frame in the monitoring video, and saving the key frame according to the storage path of the key frame recorded in the metadata, so that users can find the monitoring video according to the metadata. The monitoring video storage method provided by the invention can greatly reduce the reading amount of the monitoring video, and effectively improve the query efficiency.

Description

technical field [0001] The present invention relates to the technical field of surveillance, and more specifically, to a method for storing surveillance videos. Background technique [0002] With the increase of video types and the increasing amount of data, how to effectively organize and manage these data so that people can easily find relevant video clips they are interested in from a large amount of video data has become an urgent need. The technology to meet this requirement is the content-based video retrieval technology that people are generally concerned about. Content-based video search engines can greatly improve the efficiency and accuracy of video retrieval, and play an important role in promoting the sharing and effective use of videos. Not only has important theoretical research significance, but also has broad application prospects, which can drive the development of the emerging industry of video search. [0003] An existing key frame-based video stream ind...
