Building screen lamp monitoring method and system based on video recognition

Abstract

The invention provides a building screen lamp monitoring method and system based on video recognition. The building screen lamp monitoring method comprises the following steps of S1, obtaining a videosource file played by a screen; S2, playing the video source file, and performing live-action shooting on the played video through a high-definition camera to obtain an actual video file; S3, performing segmented interception on the actual video file to obtain an actual video file interception picture; performing segmented interception on the video source file to obtain a video source file interception picture; and S4, performing comparative analysis on the actual video file intercepted image and the video source file intercepted image, and feeding back the lamp state information of the screen according to a comparative analysis difference result. When the lamp of the building media screen needs to be checked, workers do not need to check on site any more, and the checking difficulty of the lamp of the screen and the workload of maintenance personnel are effectively reduced; and positioning can be accurately achieved, and later maintenance is facilitated.

[0002] Nowadays, LED screens are widely used. For example, large screens are often used in the construction media industry. , the video cannot be displayed and played normally, affecting the playback effect of the video, and may even cause misleading; and in traditional technology, if you want to check the actual working status of the lamps and lanterns on the screen, you must manually check on the spot, which requires huge human resources; construction The video source played by the media screen is generally complex in content and rich in color, which will make the working status of the lamps also complicated and changeable. When manually inspecting the huge architectural media screen on site, some subtle lamps that are not working properly are difficult to detect. It is found; after checking the abnormal lamps, it is difficult to accurately locate the specific location of the bad lamps, which is not convenient for later maintenance
