Description

Technical Field

[0001] This application relates to the field of video wall display technology, and in particular to a method for displaying a video wall background image, an electronic device, and a computer-readable storage medium. Background Technology

[0002] A video wall is a large-screen display system composed of multiple display devices (such as LCD screens and LED screens). During the display process, the speed at which the background image is uploaded directly affects the system's response time and user experience. Existing methods for displaying background images on video walls require transmitting the complete background image data to each display device, resulting in a high network load and slow upload speed. Therefore, improving the upload speed of the background image has become an urgent problem to be solved. Summary of the Invention

[0003] The main technical problem addressed by this application is to provide a method for displaying background images on a video wall, which can improve the speed of displaying background images on the wall.

[0004] To address the aforementioned technical problems, this application provides a method for displaying a background image on a video wall. The video wall includes multiple display devices. The method includes: acquiring a background image to be displayed and determining the image type of the background image; segmenting the background image to be displayed based on the image type and the distribution of the display devices to obtain multiple display images and determining the image type of each display image; generating a corresponding display instruction based on the image type and sending the display instruction to the display devices to display a target image based on the display instruction; wherein, when the image type matches multiple pixel values, the target image corresponds to the display image; when the image type matches a single pixel value, the target image is generated from the corresponding pixel value.

[0005] To address the aforementioned technical problems, a second aspect of this application provides an electronic device including a memory and a processor coupled to each other, wherein the memory stores program instructions and the processor executes the program instructions to implement the method described in the first aspect.

[0006] To address the aforementioned technical problems, a third aspect of this application provides a computer-readable storage medium storing program instructions executable by a processor, the program instructions being used to implement the method described in the first aspect.

[0007] The above solution obtains the background image to be displayed and determines its image type. Based on the image type and the distribution of display devices, the background image is divided into multiple display images, and the image type of each display image is determined. A corresponding display instruction is generated based on the image type and sent to the display device so that the display device can display the corresponding target image based on the received display instruction. Specifically, when the image type matches multiple pixel values, the target image is the display image; when the image type matches a single pixel value, the target image is generated from the corresponding pixel value. By determining the image type, it is not necessary to transmit the complete image data to the corresponding display device for display every time, thus shortening the time for displaying the background image on the wall and improving the speed of displaying the background image on the wall.

[0013] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments, and different implementation methods can be adaptively combined. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0014] In this paper, the terms "system" and "network" are often used interchangeably. The term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone.

[0015] Please see Figure 1 , Figure 1 This is a flowchart illustrating one embodiment of the video wall background image display method of this application. The video wall includes multiple display devices, and the method includes:

[0016] S101: Obtain the background image to be displayed and determine the image type of the background image to be displayed.

[0017] Specifically, obtain the background image to be displayed on the wall and determine the image type of the background image to be displayed.

[0018] In one application method, the image type of the background image to be displayed is determined based on the pixel values ​​corresponding to the pixels in the background image to be displayed.

[0019] It is understandable that pixel values ​​are usually composed of three color components: R (RED), G (GREEN), and B (BLUE). For example, the pixel values ​​of a 24-bit true color image may be represented as (R, G, B), with each component occupying 8 bits (0-255). The RGB values ​​are the specific values ​​of these three color components.

[0020] In some application scenarios, when the pixel values ​​of all pixels in the background image to be displayed are (255, 0, 0), where the RGB values ​​are R=255, G=0, B=0 respectively, the color of the background image to be displayed is pure red, indicating that the corresponding image type is a solid color type.

[0021] In some application scenarios, when a portion of the pixels in a certain area of ​​the background image to be displayed have a pixel value of (255, 255, 0), where the RGB values ​​are R = 255, G = 255, B = 0, and a portion of the pixels in another area have a pixel value of (0, 255, 0), where the RGB values ​​are R = 0, G = 255, B = 0, it indicates that the background image to be displayed is a combination of yellow and green, and the corresponding image type is a regular type.

[0022] In another application, the information entropy of the background image to be displayed is obtained, and the image type of the background image to be displayed is determined based on the information entropy.

[0023] It should be noted that solid color images have extremely low information entropy, while regular image types have higher information entropy.

[0024] S102: Based on the image type of the background image to be displayed and the distribution of display devices, the background image to be displayed is segmented to obtain multiple display images and the image type of the display images is determined.

[0025] Specifically, based on the image type of the background image to be displayed and the distribution of display devices, the background image to be displayed is divided into multiple display images, and the image type of each display image is determined.

[0026] In one application, when the image type of the background image to be displayed is a regular type, the background image to be displayed is divided into multiple display images based on the distribution of display devices on the video wall and the resolution information of each display device, and the image type of each display image is determined.

[0027] In some application scenarios, when the image type of the background image to be displayed is a regular type, the position of each display device relative to the entire video wall is determined, the resolution information of each display device is obtained, and the background image to be displayed is divided into multiple display images according to the position and resolution information of the display devices, and the image type of each display image is determined.

[0028] In a specific application scenario, when the background image to be displayed is of a regular type, assume there are two horizontally arranged display devices. The left one is labeled display device A with a resolution of 1920×1080, and the right one is labeled display device B with a resolution of 1280×1080. Establish a global coordinate system with display device A as the origin. Then the position coordinates of display device A are (0,0), and the position coordinates of display device B are (1920,0). The global resolution is (1920+1280)×1080. Scale the background image to be displayed to 3200×1080, thus dividing it into a 1920×1080 display image on the left and assigning it to display device A, and a 1280×1080 display image on the right and assigning it to display device B. Determine the image type based on the pixel values ​​corresponding to the pixels in each display image.

[0029] In another application, when the image type of the background image to be displayed is a regular type, the background image to be displayed is divided into multiple display images based on the distribution of the display devices on the video wall and the semantics of the image content of the background image to be displayed, and the image type of each display image is determined.

[0030] In some application scenarios, when the image type of the background image to be displayed is a regular type, the position of each display device relative to the entire video wall is determined, the semantics of the image content of the background image to be displayed are obtained, and the background image to be displayed is divided into multiple display images according to the position of the display device and the semantics of the image content of the background image to be displayed, and the image type of each display image is determined.

[0031] In a specific application scenario, when the image type of the background image to be displayed is a regular type, assuming there are three horizontally arranged display devices, labeled as display device A, display device B, and display device C from left to right, a neural network model is used to obtain the semantics of the image content of the background image to be displayed. The image content corresponding to the central position of the background image to be displayed is the target object, and the image content corresponding to the two side edges is the blurred background. Therefore, the background image to be displayed is divided into three display images. The display image containing the target object is assigned to display device B, and the display images with blurred backgrounds are assigned to display devices A and C respectively. The image type is determined based on the pixel values ​​corresponding to the pixels in each display image.

[0032] S103: Generate corresponding display instructions based on image type, and send the display instructions to the display device so that the display device can display the target image based on the display instructions.

[0033] Specifically, a corresponding display instruction is generated based on the image type, and the display instruction is sent to the display device so that the display device can display the corresponding target image based on the received display instruction. When the image type matches multiple pixel values, the target image corresponds to the display image. When the image type matches a single pixel value, the target image is generated from the corresponding pixel value.

[0034] In one application method, a corresponding type field and display field are generated based on the image type, a display instruction is generated based on the type field and display field, and the display instruction is sent to the display device so that the display device displays the target image based on the type field and display field.

[0035] In another application, an instruction generation model is pre-trained. After obtaining the image type, the image content is analyzed using the model to generate corresponding display instructions. These instructions are then sent to the display device so that the device can display the target image based on the type and display fields.

[0036] It is understandable that when the background image to be displayed is a solid color, there is no need to segment the background image. Instead, the pixel values ​​corresponding to the pixels of the display image are obtained, and the target image is directly generated based on the corresponding pixel values.

[0037] The above solution obtains the background image to be displayed and determines its image type. Based on the image type and the distribution of display devices, the background image is divided into multiple display images, and the image type of each display image is determined. A corresponding display instruction is generated based on the image type and sent to the display device so that the display device can display the corresponding target image based on the received display instruction. Specifically, when the image type matches multiple pixel values, the target image is the display image; when the image type matches a single pixel value, the target image is generated from the corresponding pixel value. By determining the image type, it is not necessary to transmit the complete image data to the corresponding display device for display every time, thus shortening the time for displaying the background image on the wall and improving the speed of displaying the background image on the wall.

[0038] Please see Figure 2 , Figure 2 This is a flowchart illustrating another embodiment of the TV wall background image display method of this application. The method includes:

[0039] S201: Obtain the base image, pre-decode the base image to obtain the base image to be displayed and the pixel values ​​corresponding to the pixels in the base image to be displayed.

[0040] Specifically, the base image is obtained, and the image decoding module is called to pre-decode the base image to obtain the decoded base image to be displayed and the pixel values ​​corresponding to the pixels in the base image to be displayed.

[0041] S202: Determine the image type of the background image to be displayed based on the pixel values ​​corresponding to the pixels in the background image to be displayed.

[0042] Specifically, based on the pixel values ​​corresponding to the pixels in the background image to be displayed, the image type corresponding to the background image to be displayed is determined. The background image to be displayed is obtained by pre-decoding the background image, which avoids the real-time decoding operation when the background image is displayed on the wall, significantly shortens the display time of the background image on the TV wall, and thus improves the speed of displaying the background image on the wall.

[0043] S203: Based on the image type of the background image to be displayed and the distribution of display devices, the background image to be displayed is segmented to obtain multiple display images and the image type of the display images is determined.

[0044] Specifically, based on the image type of the background image to be displayed and the distribution of display devices, the background image to be displayed is divided into multiple display images, and the image type of each display image is determined.

[0045] In one implementation scenario, step S203 specifically includes: matching multiple pixel values ​​in response to the image type of the background image to be displayed, segmenting the background image to be displayed based on the distribution of the display device, obtaining multiple display images, and determining the image type of the display images.

[0046] Specifically, when the image type of the background image to be displayed matches multiple pixel values, that is, when the image type of the background image to be displayed is a regular type, the background image to be displayed is segmented based on the distribution of the display devices on the video wall to obtain multiple display images, and the image type of each display image is determined.

[0047] In one implementation scenario, when the image type of the background image to be displayed matches a single pixel value, that is, when the image type of the background image to be displayed is a solid color, step S203 is skipped and step S204 is executed directly.

[0048] S204: Generate corresponding display instructions based on image type, and send the display instructions to the display device so that the display device can display the target image based on the display instructions.

[0049] Specifically, a corresponding display instruction is generated based on the image type, and the display instruction is sent to the display device so that the display device can display the corresponding target image based on the received display instruction.

[0050] In one implementation scenario, when the image type of the background image to be displayed matches a single pixel value, i.e., the image type of the background image to be displayed is a solid color, step S204 specifically includes: generating a corresponding solid color type field and a pixel value display field based on the single pixel value; generating a display instruction based on the solid color type field and the pixel value display field; sending the display instruction to the display device so that the display device confirms the validity of the pixel value display field based on the solid color type field, generates a target image based on the corresponding pixel value, and displays the target image on the corresponding display device.

[0051] Specifically, based on a single pixel value, a corresponding solid color type field and pixel value display field are generated. Based on the solid color type field and pixel value display field, a corresponding display instruction is generated and sent to the display device. After receiving the display instruction, the display device parses the instruction to obtain the solid color type field contained in the display instruction. Then, based on the solid color type field, it confirms that the pixel value display field is valid. Based on the corresponding pixel value, the target image is generated and displayed on the corresponding display device. There is no need to perform image segmentation operations, which further shortens the time for the base map to be displayed on the wall.

[0052] In a specific implementation scenario, when the background image to be displayed only matches pure red pixel values, the image type of the background image to be displayed is a solid color type. Based on the pure red pixel values, a corresponding solid color type field and a red pixel value display field are generated. Based on the solid color type field and the red pixel value display field, a corresponding display instruction is generated and broadcast to all display devices via a multicast protocol. After receiving the display instruction, each display device parses the solid color type field contained in the instruction, then confirms the validity of the pure red pixel value display field based on the solid color type field, thereby generating the target image based on the corresponding pure red pixel values ​​and displaying the target image on the corresponding display device.

[0053] Optionally, when the pixels of the background image to be displayed contain only the single red channel, as long as the corresponding pixel value is greater than a preset threshold, the image type of the background image to be displayed can be considered as a solid color type. For example, if the preset threshold is set to 250, the pixel value corresponding to 98% of the pixels of the background image to be displayed is (255,0,0), and the pixel value corresponding to the remaining 2% of the pixels is (251,0,0), then the image type of the background image to be displayed can also be considered as a solid color type.

[0054] In one implementation scenario, the display device is assigned a number. Before step S204, the method further includes: generating corresponding pixel value information and associating the pixel value information with the display device's number. Step S204 involves sending a display instruction to the display device so that the display device can confirm the validity of the pixel value display field based on the solid color type field. The steps of generating a target image based on the corresponding pixel value and displaying the target image on the corresponding display device specifically include: sending a display instruction to the display device based on the number so that the display device can confirm the validity of the pixel value display field based on the solid color type field; determining the corresponding pixel value based on the pixel value information; generating a target image based on the corresponding pixel value; and displaying the target image on the corresponding display device.

[0055] Specifically, the display instruction is sent to the display device according to the number of each display device. After receiving the display instruction, the display device parses the instruction to obtain the solid color type field contained in the display instruction, then confirms the validity of the pixel value display field based on the solid color type field, generates the target image based on the corresponding pixel value, and displays the target image on the corresponding display device.

[0056] In other implementation scenarios, the video wall control system can also directly send display commands to all display devices; this application does not impose specific restrictions on this.

[0057] In one implementation scenario, among multiple display devices, there is a corresponding master device. Each display device has a corresponding number, and the storage path of the master device is shared with other display devices. Before step S204, the method further includes: in response to matching multiple pixel values ​​for the image type of the displayed image, naming the displayed image based on the number of the display device, and storing the displayed image in the storage path of the master device; in response to matching a single pixel value for the image type of the displayed image, generating corresponding pixel value information, and associating the pixel value information with the corresponding display device number.

[0058] Specifically, when the image type of the displayed image matches multiple pixel values, the displayed image is named based on the display device number, and all displayed images are stored in the shared storage path of the main device. When the image type of the displayed image matches a single pixel value, the corresponding pixel value information is generated and associated with the corresponding display device number. Through the shared path configuration, the displayed image only needs to be stored on the main device, and other display devices can access the shared storage path. The pixel value information only needs to be associated with the corresponding display device number, avoiding the need to repeatedly transmit the displayed image to each display device and greatly reducing the transmission load of the system network.

[0059] It is understandable that after the background image to be displayed is divided into multiple display images, the image type of the display images can include solid color type and regular type, or only regular type.

[0060] In one implementation scenario, step S204 specifically includes: responding to a single pixel value matching the image type of the displayed image, generating a corresponding pixel value display field and a solid color type field based on the single pixel value, generating a display instruction based on the pixel value display field and the solid color type field, sending the display instruction to the corresponding display device based on a number, so that the display device confirms the validity of the pixel value display field based on the solid color type field, determining the corresponding pixel value based on the corresponding pixel value information, generating a target image based on the corresponding pixel value, and displaying the target image on the corresponding display device; responding to multiple pixel values ​​matching the image type of the displayed image, generating a corresponding main device storage path field and a regular type field based on the display device number, generating a display instruction based on the main device storage path field and the regular type field, sending the display instruction to the corresponding display device based on a number, so that the display device confirms the validity of the main device storage path field based on the regular type field, and retrieving the display image from the main device storage path as the target image based on the display device number, and displaying the target image on the corresponding display device.

[0061] Specifically, when the image type of the displayed image matches a single pixel value, a corresponding pixel value display field and a solid color type field are generated based on the single pixel value. A corresponding display instruction is then generated based on the pixel value display field and the solid color type field and sent to the display device. After receiving the display instruction, the display device parses the instruction to obtain the solid color type field contained in the display instruction. Then, it confirms the validity of the pixel value display field based on the solid color type field, generates the target image based on the corresponding pixel value, and displays the target image on the corresponding display device, thus realizing the rapid display of the base image on the wall.

[0062] In one implementation scenario, generating a target image based on corresponding pixel values ​​and displaying the target image on the corresponding display device specifically includes: generating a target image by calling the screen clearing command of the display device based on corresponding pixel values ​​and displaying the target image on the corresponding display device; or generating a target image by calling the fill function of the display device based on corresponding pixel values ​​and displaying the target image on the corresponding display device.

[0063] Specifically, based on the corresponding pixel values, the screen clearing command of the display device is invoked to generate the target image, and the target image is displayed on the corresponding display device. Alternatively, the fill function of the display device is invoked to generate the target image, and the target image is displayed on the corresponding display device. This eliminates the need to retrieve the corresponding display image from the shared storage path, and instead directly generates the target image based on the corresponding pixel values, reducing the image data transmission time and further improving the speed of mounting the base map on the wall.

[0064] In a specific implementation scenario, the GPU is used to call screen clearing instructions, such as OpenGL's glClearColor, or COU's memory filling function, such as Linux Framebuffer's memset, to generate the corresponding target image based on the corresponding pixel values ​​and display the target image on the corresponding display device.

[0065] Furthermore, when the image type of the displayed image matches multiple pixel values, a corresponding storage path field and general type field of the main device are generated based on the display device number. Based on the storage path field and general type field of the main device, a corresponding display instruction is generated and sent to the corresponding display device according to the display device number. After receiving the display instruction, the display device parses the instruction to obtain the general type field contained in the display instruction. Then, based on the general type field, it confirms that the storage path field of the main device is valid. Based on the display device number, it retrieves the display image from the shared storage path of the main device as the target image and displays the target image on the corresponding display device.

[0066] In the above scheme, when the image type of the background image to be displayed is a solid color, there is no need to segment the background image. Instead, a display command is directly generated and sent to the display device. After parsing the command, the display device confirms that the corresponding pixel value display field is valid and generates the corresponding target image based on the corresponding pixel value, which is then displayed on the display device. When the image type of the background image to be displayed is a regular type, the background image is segmented to obtain multiple display images. A display command is then generated and sent to the display device. When the image type of the display image is a solid color, the display device confirms that the corresponding pixel value display field is valid after parsing the command and generates the corresponding target image based on the corresponding pixel value, which is then displayed on the display device. When the image type of the display image is a regular type, the corresponding display image is retrieved from the shared storage path of the main device according to its number and displayed as the target image on the corresponding display device. Thus, when the image type is a solid color, there is no need to obtain image data; the target image is directly generated based on the pixel value. When the image type is a regular type, the display image is retrieved from the shared storage path of the main device according to its number as the target image. This facilitates quick location and acquisition of image data by each device, improving the speed of background image display.
