The embodiment of the invention provides a video scene change detection method, a device thereof and video acquisition equipment, wherein, the method comprises the steps of obtaining a first block scene fluctuation array of a first video code stream; acquiring a second block scene fluctuation array of the second video stream; judging whether the video scene of the second video stream is stable ornot based on the second block scene fluctuation array; when the video scene of the second video bit stream is stable, detecting the change of the video scene through the first block scene fluctuationarray and the second block scene fluctuation array. The method comprises the steps of firstly determining the stability of the detected video scene, and then detecting the change of the video scene, and detecting the stability of the video scene by using the fluctuation of the video scene, so that the interference of the noise generated by the video capture device on the judgment of the change ofthe video scene can be eliminated, and the accuracy of the change detection of the video scene can be improved.
Description
Technical field [0001] The invention relates to the field of video monitoring, in particular to a detection method, device and video acquisition equipment for video scene changes. Background technique [0002] In a video surveillance system, a video capture device is an indispensable device for scene monitoring. Among them, the camera is the most widely used. The camera needs to use automatic exposure, automatic focus, automatic white balance and other algorithms to adjust the camera parameters according to the image conditions of the current scene to ensure that the output image is in a high-quality state, which is reflected in the clear image, correct exposure, and correct color. [0003] In many camera application scenarios, the shooting target may change. For example, people enter or leave, the distance of the subject from the camera changes, and the proportion of the subject in the screen changes. This may cause image quality problems such as blurred images or color distorti...
