Abstract

The invention relates to a monitoring scene change determination method, device and system and an electronic device.The monitoring scene change determination method comprises the steps that whether a hardware interrupt message is generated or not is determined, and the hardware interrupt message is used for indicating that a monitoring scene changes; if yes, the hardware interrupt message is packaged into the collected video code stream, so that the video code stream analysis equipment determines the video frame with the scene change according to the hardware interrupt message, the problem of high computing resource consumption during monitoring scene recognition is solved, and the efficiency of determining the monitoring scene is improved.

Description

technical field [0001] The present application relates to the field of computer vision, in particular to a scene change determination method, device, system and electronic device. Background technique [0002] When performing real-time video abnormal event detection, the movement speed and direction of the target object in the video screen will be affected when the monitoring scene changes, resulting in a large number of false alarms of video abnormal events. [0003] In the existing scheme, it is mainly to obtain multi-frame image data in the video data segment, extract the feature information in the multi-frame image data, and determine whether the monitoring scene has changed according to the current feature information and historical feature information, but the existing The method needs to perform feature extraction on multi-frame images, which requires a lot of computing resources, resulting in the problem of high computing resource consumption in monitoring scene reco...
