Embodiment Construction

[0095] Embodiments of the present application provide a video frame detection and processing method, device, system, and storage medium, which can be applied to the field of video stream detection. The video stream detection system includes a terminal and a video processing device communicating with the terminal. In the video stream detection system, the terminal is used to detect whether the video stream received from the video processing device is abnormal.

[0096] The detection method of this video frame can be applied to different systems, such as being applied to a video surveillance system, and the video surveillance system can be figure 1 In the home monitoring system shown, the monitoring device is the video processing device provided in the embodiment of the present application, and is used to send the video stream to the terminal, and the terminal is used to detect whether the video stream sent by the monitoring device is abnormal.

Abstract

The invention provides a method, apparatus and system for detecting and processing video frames. The method comprises the following steps: receiving the video stream sent by a video processing device,wherein the video stream comprises a plurality of video frames arranged according to a time sequence, and each video frame in the video stream carries a mark; extracting the marks of at least two video frames arranged according to the time sequence from the video stream; and determining whether the incidence relation between the marks of at least two video frames arranged according to the time sequence in the video stream meets a preset first change rule, and if not, determining that the video stream is abnormal. By adoption of the scheme, the accuracy and the efficiency of detecting the abnormality of the video stream can be improved.

Description

technical field [0001] The present application relates to the field of media stream technologies, and in particular to a video frame detection and processing method, device and system. Background technique [0002] When deploying a video surveillance system, it is necessary to check the quality of the monitored video. Generally, the deployment personnel observe the video played on the screen of the terminal connected to the video surveillance system with the naked eye, and observe whether the video has dropped frames or freezes. Or blurred screen phenomenon, but this detection method is time-consuming and laborious, and there are also misjudgments or subjectivity. In order to improve the detection efficiency, at present, the method of similarity comparison is mainly used for detection, that is, to obtain continuous multi-frame pictures in the video to be detected, and to determine that the similarity between each adjacent two frames of pictures in the continuous multi-frame ...
