Synchronous transmission control method for digital retina video stream and characteristic stream

Abstract

The invention provides a synchronous transmission control method and device for a digital retina video stream and a feature stream, electronic equipment, network video monitoring equipment and a computer readable medium. The method comprises the following steps: acquiring a monitoring video stream; generating a concentrated video stream corresponding to the monitoring video stream by adopting a video concentration technology; extracting feature information in the monitoring video stream to form a feature stream; and respectively uploading the concentrated video stream and the feature stream toa cloud server. Because the concentrated video stream has the advantages of small occupied storage space, high fidelity factor and the like, compared with a mode of uploading all monitoring video streams to a cloud server in the prior art, the method has the advantages of small occupied storage space, low network transmission load, high transmission efficiency and the like; meanwhile, the featurestream is extracted according to the monitoring video stream and uploaded to the cloud server, thereby facilitating the quick recognition of the positioning target and the mining of the movement track of the positioning target, and effectively improving the retrieval efficiency of the monitoring video.

Description

technical field [0001] This application relates to the technical field of security monitoring, in particular to a method and device for synchronous transmission control of digital retinal video streams and feature streams, an electronic device, a network video monitoring device, and a computer-readable medium. Background technique [0002] With the rapid development of computer technology and Internet technology, network surveillance cameras have gradually replaced the traditional local surveillance system and have been widely popularized. By uploading the collected surveillance video to the cloud server, users can view and monitor in different places anytime and anywhere. Video recording for remote monitoring. [0003] However, on the one hand, in the prior art, the above-mentioned surveillance videos are still mainly encoded using H.264 and other encoding technologies, which have problems such as low data compression efficiency, large storage space occupation, and heavy ne...

Problems solved by technology

[0003] However, on the one hand, in the prior art, the above-mentioned surveillance videos are still mainly encoded using H.264 and other encoding technologies, which have problems such as low data compression efficiency, large storage space occupation, and heavy network transmission load; on the other hand, the existing The technology often uploads all the surveillance videos collected around the clock to the cloud server. The data redundancy is very high, but it is difficult to extract global valuable information, resulting in huge waste of information, and there is a large waste of storage space and network bandwidth; On the other hand, in the application, surveillance video has the problems of slow video access and difficult analysis. How to find important and valuable clues from massive videos, such as quickly identifying and locating targets and mining their action trajectories, can shorten the event processing time. , reducing work intensity and improving work efficiency is of positive significance
