Embodiment approach

[0235] As an implementation manner of an embodiment of the present invention, when the feature information includes: reference picture, spatial range, time range, and attribute information,

[0236] Any target storage node 920 is specifically used to perform feature extraction on the reference picture to obtain the picture feature information corresponding to the reference picture; search for a video that matches the spatial range and time range in the locally stored monitoring video index information. Candidate surveillance video index information; in the candidate surveillance video index information, read the surveillance video corresponding to each candidate surveillance video index information in turn, and use the pre-configured feature algorithm to extract the video feature information of the surveillance video, according to the surveillance video The video feature information, and the picture feature information and the attribute information, calculate the matching degre...

Abstract

An embodiment of the present invention provides a video search method, The method comprises the following steps: a management node receives a video search request sent by a client, which includes characteristic information of a video to be searched and monitored, wherein, the characteristic information comprises at least one of the following items: a reference picture, a spatial range, a time range, and attribute information; the management node determines a target storage node storing the monitored video to be searched, and sends the video search request to each of the target storage nodes; Each of the target storage nodes receives the video search request, According to the locally stored surveillance video, the stored surveillance video index information, and the feature information, target monitoring video index information whose matching degree with the feature information is greater than a first preset threshold value is searched, and the target monitoring video index informationis sent to the management node. The embodiment of the invention can realize the searching of the monitoring video in the cloud storage system.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a video search method, device, cloud storage system and computer equipment. Background technique [0002] With the continuous development of video surveillance technology, the construction of safe cities, intelligent communities, and intelligent transportation is becoming more and more common, and the application of video surveillance is becoming more and more extensive. This will lead to a geometric exponential growth of surveillance video. [0003] In order to meet the storage of massive surveillance video, cloud storage system came into being. Specifically, the cloud storage system may include a management node and multiple storage nodes, and the surveillance video collected by the front-end monitoring equipment needs to be written into the cloud storage system through the access node. In the process of monitoring video storage, such as figure 1 As shown, the data ...
