Example

[0027] [First Embodiment]

[0028] See figure 1 , Which is a method for detecting an abnormality in a display screen playback image according to the first embodiment of the present invention, and includes the following steps:

[0029] 101. The picture acquisition step is to acquire periodically shot live pictures, where the live pictures include a playback picture of a target display screen.

[0030] When performing abnormal detection on the playback screen of the target display screen, it is necessary to obtain the playback screen of the target display screen in real time, and the target display screen can play its content normally. For example, a camera device is used to periodically obtain the live image of the target display screen, for example, the period is set to 1. A live image of the target display screen is acquired every minute. The live image also includes information about the surrounding environment of the target display screen installation location, or obstructions in ...

Example

[0051] [Second embodiment]

[0052] See Figure 5 , The second embodiment of the present invention provides a device for detecting an abnormality of a display screen playback picture. The detecting device 10 includes a picture acquisition module 11, an image extraction module 12, a detection analysis module 13, and a fault notification module 14.

[0053] The image acquisition module 11 is used to acquire periodically shot live images, the live images include the playback images of the target display screen, and the first embodiment of the live images is described in detail; the image extraction module 12 is used to obtain images from the images The scene screen obtained in module 11 extracts images according to the target area to obtain multiple consecutive detection images, and each of the consecutive multiple detection images has different contents of two adjacent detection images, and the target area is located in the Within the area where the playback screen of the target disp...

Example

[0064] [Third embodiment]

[0065] Refer to FIG. 9, which is the third embodiment of the present invention, and provides a display screen playback picture abnormality detection system. The detection system 20 includes a cloud server 21. The cloud server 21 is connected to at least one camera 22, and one target is displayed. The screen 23 is arranged corresponding to a camera 22. The camera 22 is used to periodically obtain the live screen containing the playback screen of the target display screen 23, and remotely transmit the live screen to the cloud server 21 via the network, and the cloud server 21 implements the method for detecting abnormality of the screen playback screen of the first embodiment above , Or the cloud server 21 has the device for detecting an abnormality of the display screen playback image of the second embodiment described above.

[0066] In one embodiment, the display screen playback picture abnormality detection system 20 includes, for example, a processor...

Abstract

The embodiment of the invention discloses a display screen playing picture anomaly detection method, device and system. The display screen playing image anomaly detection method comprises the steps of: a surface acquisition step, acquiring a periodically shot field image which comprises a playing image of a target display screen; an image extraction step, continuously extracting images in a targetarea in the field picture, wherein the content of every two adjacent detection images in the plurality of continuous detection images is different, the target area is located in an area where the playing image of the target display screen is located in the field image, and the number of the plurality of continuous detection images is greater than or equal to 3; a detection analysis step, performing image analysis processing on the at least three continuous detection images to judge whether the playing image of the target display screen has a fault or not; and a failure notification step.

Description

technical field [0001] The present invention relates to the technical field of image analysis and video playback picture detection, and in particular to a display screen play picture abnormality detection method, a display screen play picture abnormality detection device and a display screen play picture abnormality detection system. Background technique [0002] At present, the target display screen is widely used, and the target display screen is used to play advertisements, promotional videos and other content. Especially the LED target display, but if the target display fails, such as black blocks, bright blocks, and large-area black screens, if it is not found and resolved in time, it will cause greater losses to users. [0003] The existing LED target display detection method is: the LED target display plays a test picture, the test picture is a solid color picture, and by analyzing the solid color picture displayed on the LED target display, it is known whether the LE...
