The invention provides a multi-scene video monitoring method and a device thereof, and the method is applied to a monitoring device which monitors N scenes through an analysis monitoring module of M monitoring paths, where N is greater than M; the method comprises the following steps: acquiring video stream data of N scenes; receiving a maximum value Y of the number of scenes which may have a predetermined target at the same time in the N scenes; extracting a frame of picture from the video stream data of each scene at an interval of a first preset duration to form a first picture stream; judging whether a predetermined target exists in the pictures in the first picture stream or not through an X-path analysis monitoring module; wherein the path number of the X paths is not greater than the difference between M and Y; and when the picture in the first picture stream has the predetermined target, analyzing and monitoring the video stream data of the scene corresponding to the picture with the predetermined target. According to the method, each video channel does not need to be always kept in an analysis open state, resources can be saved, and the intelligent analysis performance isgreatly improved.
Description
technical field [0001] The invention relates to the technical field of intelligent video monitoring, in particular to a multi-scene video monitoring method and device. Background technique [0002] With the wide application of video surveillance services, video surveillance services are often used to monitor abnormal events in some scenarios. [0003] At present, in order to monitor abnormal events in some scenes, it is generally to set up multiple cameras in these scenes to collect real-time video in corresponding scenes, and then monitor and analyze several independent real-time video channels respectively; specific , using the tracking relationship of the target in the front and back frames in the video channel to identify whether there are abnormal events that violate the established rules in the image frames of each real-time video channel. [0004] However, the existing methods need to keep the analysis turned on for each video channel, which will cause waste of resou...
