Abstract

The invention discloses a video retrieval method for a video cloud storage system. The method comprises: adding feature information of a shooting object into a video frame; establishing a data block index and a frame index in a cloud storage management cluster and a video storage cluster of the video cloud storage system respectively to establish a multilayer index structure; and performing video retrieval successively for a camera ID, shooting time and the feature information of the shooting object, so that the purposes of quickly reducing a retrieval range in huge video data and accurately obtaining a retrieval result are achieved. Meanwhile, the content of texts, pictures, audios and videos and the like can be analyzed by utilizing various algorithms in the method provided by the method, so that the search in multiple diversified search conditions is realized. Compared with the prior art, the method has the advantages that a large amount of events of manually searching for required video content and tracking monitoring targets are reduced, and the efficiency of searching for videos in massive video data is greatly improved.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a retrieval method of a video cloud storage system in video monitoring. Background technique [0002] Video cloud storage system is an important part of video surveillance, and plays a core role in large-scale video surveillance networks such as safe city video surveillance. [0003] Such as figure 1 As shown, the video cloud storage system is mainly composed of a cloud storage management cluster and a video storage cluster, and the cloud storage management cluster and the video storage cluster are connected through a network. Among them, the video storage cluster is composed of multiple video storage nodes, and each video storage node stores video data from the camera. The video storage cluster is a cluster composed of devices that store video data in the video cloud storage system; the cloud storage management cluster consists of Composed of multiple management nodes, each man...
