Abstract

The invention discloses a video stream processing method, device and equipment, and a storage medium. The method comprises the steps of determining an optical stream sequence corresponding to each path of video stream in multiple paths of acquired video streams; inputting the optical flow sequence corresponding to each path of video flow into a coarse screening classification network, and outputting a first violent sorting behavior set meeting a preset condition, the optical flow sequence corresponding to the first violent sorting behavior set being a target optical flow sequence; and inputting the target optical flow sequence into a fine screening classification network, and outputting a second violent sorting behavior set. According to the method, the requirements on hardware and software during processing of multiple paths of video streams are reduced, and the processing time is shortened.

Description

technical field [0001] The present invention generally relates to the technical field of image processing, and in particular to a video stream processing method, device, equipment and storage medium. Background technique [0002] With the advancement of technology, video surveillance has become an important part of the security system. Now the coverage of video surveillance is very wide, and video surveillance is carried out in most corners. Through video monitoring, you can know the security situation within the monitoring area in real time. Of course, for evidence collection, you can also play back the video. [0003] As the coverage of video surveillance becomes wider and wider, it is necessary to analyze in real time whether there are violent incidents in all videos. At this time, it is necessary to process the video streams of multiple video surveillance at the same time, and the requirements for hardware and software for processing video streams are relatively high. ...
