Problems solved by technology
[0004] In the traditional technology, the video review is generally based on the detection and analysis of the complete video. It is difficult to accurately identify whether the video is divided into multiple screens, which leads to the problems of small effective screen ratio and low video quality due to split screen, which is difficult to be detected.

Embodiment Construction
[0044] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0045] The split-screen video detection method provided by this application can be applied to such as figure 1 shown in the application environment. Wherein, the terminal 102 communicates with the server 104 through the network. The terminal 102 sends the video to be detected to the server 104, and the server 104 performs frame sampling processing on the video to be detected to obtain an image sequence, performs edge detection on each frame in the image sequence, identifies edge pixels in the image, and identifies the edge pixels Point coordinates, according to the coord...

The invention relates to a split-screen video detection method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a to-be-detected video, performing frame extraction processing on the to-be-detected video to obtain an image sequence, performing edge detection on each frame of image in the image sequence, identifying edge pixel points in the image, identifying coordinates of the edge pixel points, according to the coordinates of the edge pixel points in the same image, detecting whether the edge pixel points form a horizontal straight line or a vertical straight line in the image to obtain a straight line detection result, and collecting the straight line detection result of each frame of image in the image sequence to obtain a split screen detection result of the to-be-detected video. By adopting the method, whether the video is segmented into a plurality of pictures can be accurately identified, and the problems of small effective picture proportion and low video quality of the video caused by screen splitting can be effectively detected based on a screen splitting detection result.
Description
technical field [0001] The present application relates to the technical field of video processing, in particular to a split-screen video detection method, device, computer equipment and storage medium. Background technique [0002] With the development of multimedia technology, video, as a kind of multimedia information, has been widely disseminated on major video platforms. Major video platforms also need to review videos, such as video content review and video quality inspection. [0003] As video display methods become more and more diverse, videos displayed in various forms appear. For example, there are multiple images in the video to be played simultaneously, or the horizontal screen video is re-made into a vertical screen video suitable for mobile phone display. Since the same screen may exist in multiple screens played at the same time, when the horizontal screen video is converted to the vertical screen video, the upper and lower parts of the vertical screen video...
