[0040] Figure 2 is a flowchart of a control method of a spliced display screen according to an embodiment of the present application. As shown in Figure 2 the method can include the following steps:

[0041] In step S201, image information of the spliced display screen collected by machine vision is acquired, wherein the spliced display screen includes a plurality of sub-displays.

[0042] In the technical solution provided by the above step S201 of the present application, the spliced display screen can be a large liquid crystal display screen spliced by a plurality of sub-displays, wherein the sub-display can be a small liquid crystal display screen constituting the spliced display screen, for example, four sub-displays of 1920*1080 can be spliced into a complete spliced display screen of 3840*2160.

[0043] In this embodiment, the image information of the spliced display screen can be collected by machine vision, and the image information can be obtained, wherein the image information can be a photo obtained by taking a picture of the spliced display screen.

[0044] In this embodiment, the machine vision can be a technology that simulates human vision by using computers and image processing technology, for example, collecting the image information of the spliced display screen by machine vision can be taking a photo of the spliced display screen by the camera of a terminal device, and the terminal device can be a mobile phone, a computer, etc., and the type of the terminal device and the method of collecting the image information of the spliced display screen by machine vision of the terminal device are not limited here.

[0045] In step S202, based on the image information, target material information corresponding to the display areas of the plurality of sub-displays is determined from the material information to be played.

[0046] In the technical solution provided by the above step S202 of the present application, after the image information of the spliced display screen collected by machine vision is acquired, the target material information corresponding to the display areas of the plurality of sub-displays can be determined from the material information to be played according to the image information, wherein the material information to be played can be the overall picture content to be played on the spliced display screen, and the target material information can be the partial picture content to be played on the display area of the sub-display constituting the spliced display screen.

[0047] In this embodiment, the splicing relationship of each sub-display in the splicing display can be obtained based on image information. Then, the material information to be played is segmented based on the splicing relationship to obtain the sub-material information corresponding to each sub-display. After that, the border size of each sub-display in the image information is identified by an algorithm, and the target material information corresponding to the display area of ​​the sub-display is cropped from the sub-material information corresponding to each sub-display based on the proportion of the identified border size to the corresponding sub-display size.

[0048] Optionally, an algorithm can be used to identify the borders of all sub-displays on the splicing display in the image information, calculate the ratio between the size of the border and the size of the splicing display, and crop the material information into target material information that is adapted to the display area of ​​multiple sub-displays based on the ratio.

[0049] Optionally, the number of sub-displays and the number of rows and columns that make up the splicing display can also be identified from the image information. Based on the obtained number and number of rows and columns, as well as the aforementioned border size or proportion, the target material information corresponding to the display area of ​​the sub-display can be determined from the material information.

[0050] It should be noted that the above method of determining the target material information corresponding to the display area of ​​the sub-display screen from the material information is only a preferred embodiment. The method of determining the target material information corresponding to the display area of ​​the sub-display screen from the material information is not specifically limited here. Any method and process for determining the target material information corresponding to the display area of ​​the sub-display screen from the material information is within the protection scope of the embodiments of this application, and will not be described in detail here.

[0051] Step S203: Send the target material information to one or more playback devices connected to multiple sub-display screens, wherein the target material information is used by the playback devices to control the sub-display screens to play and display the material.

[0052] In the technical solution provided by step S203 of the present invention, after determining the target material information corresponding to the display areas of the multiple sub-displays from the material information to be played based on image information, the target material information can be sent to one or more playback devices connected to the multiple sub-displays. The playback device can be a playback control device for the sub-displays, such as a playback box device, which can be used to control the sub-displays to play and display the corresponding target material information in the display area.

[0053] Optionally, each sub-display screen is controlled by one or more corresponding playback devices, which can be uniquely identified by an identification code or serial number.

[0054] In this embodiment, the identification code or serial number of the playing device of the sub-display in the image information of the spliced display screen can be recognized, the target material information corresponding to the sub-display is selected according to the recognition result, and the target material information is sent to the playing device connected to the sub-display, so that the playing device of the sub-display can accurately play the corresponding target material information.

[0055] Through the above steps S201 to S203, the image information of the spliced display screen collected by the machine vision method is obtained, wherein the spliced display screen includes a plurality of sub-displays; based on the image information, the target material information corresponding to the display area of each sub-display is determined from the material information to be played; and the target material information is sent to one or more playing devices connected to the plurality of sub-displays, wherein the target material information is played and displayed by the playing device controlling the sub-display. That is, the image information of the spliced display screen can be collected by the machine vision method in the embodiment of the application. Since the spliced display screen includes a plurality of sub-displays, based on this, the material information to be played can be cropped according to the frame information of the plurality of sub-displays included in the spliced display screen to obtain the target material information corresponding to the plurality of sub-displays, and the target material information is sent to the playing device connected to the sub-display. The target material information is played and displayed by the playing device controlling the sub-display, so as to achieve the purpose of cropping the picture occupied by the frame on the spliced display screen, thereby solving the technical problem that the frame of the spliced display screen cannot eliminate the influence on the display picture ratio, and further achieving the technical effect of eliminating the influence of the frame of the spliced display screen on the display picture ratio.

[0056] It should be noted that the above-mentioned control method of the spliced display screen in the embodiment of the application can be applied to any scene of splicing LCD display screens and the like, and the application is not limited thereto. It can also be an organic light emitting display (Oranic Light Emitting Display, abbreviated as OLED) and other types of display screens. The application is not specifically limited in the application, and based on this, the application can be used in the embodiment of the application. The image information of the spliced display screen collected by the machine vision method is obtained, wherein the spliced display screen includes a plurality of sub-displays; based on the image information, the target material information corresponding to the display area of each sub-display is determined from the material information to be played; and the target material information is sent to one or more playing devices connected to the plurality of sub-displays, wherein the target material information is played and displayed by the playing device controlling the sub-display, so as to achieve the technical effect of eliminating the influence of the frame of the spliced display screen on the picture ratio.

[0057] The above method of this embodiment will be further introduced below.

[0058] As an optional implementation, in step S202, the target material information corresponding to the display area of each sub-display is determined from the material information to be played based on the image information, including: determining the splicing relationship of the sub-displays and the frame information of the sub-displays based on the image information; segmenting the material information to be played according to the splicing relationship of the sub-displays to obtain sub-material information corresponding to the sub-displays respectively; and performing picture cropping on the sub-material information based on the frame information of the sub-displays to obtain the target material information.

[0059] In this embodiment, since the image information is the image information of the spliced display, that is, the image information includes the splicing relationship of the plurality of sub-displays in the spliced display, based on this, the material information to be played can be segmented according to the splicing relationship of the plurality of sub-displays to obtain sub-material information corresponding to the plurality of sub-displays respectively, that is, the material information to be played is segmented according to the layout and splicing mode of the sub-displays to determine the sub-material information to be played corresponding to each sub-display.

[0060] For example, the material information to be played can be a complete picture, assuming that the spliced display includes 9 sub-displays, and the 9 sub-displays are arranged in the form of three rows and three columns, based on this, the material information to be played can be segmented according to the splicing mode of the sub-displays, that is, the material information to be played is segmented into 9 sub-material information of the same size, wherein the position of the sub-material information to be displayed by each sub-display in the material to be played corresponds to the position of the corresponding sub-display in the spliced display.

[0061] In this embodiment, the frame information of the plurality of sub-displays in the spliced display can also be obtained based on the image information, wherein the frame information can be the ratio information between the frame size of the sub-display and the size of the corresponding sub-display, and then the sub-material information corresponding to each sub-display is cropped based on the frame information to obtain the target material information corresponding to each sub-display.

[0062] As an optional implementation, the frame information of the sub-displays is determined based on the image information, including: identifying the frame of the plurality of sub-displays in the image information to obtain the frame information of the sub-displays, wherein the frame information is used to obtain the ratio information between the frame size of the sub-display and the size of the sub-display.

[0063] In this embodiment, after obtaining the image information of the spliced display collected by the machine vision method, the frames of the plurality of sub-displays in the image information can be identified to obtain the frame information of the plurality of sub-displays in the spliced display, wherein the frame information is the ratio information between the frame size of the sub-display and the size of the corresponding sub-display.

[0064] For example, since the image information is image information of the spliced display screen, the spliced display screen includes a plurality of sub-displays, based on this, the frame of each sub-display in the image information is identified, and the proportion information of the frame of each sub-display occupying the size of the corresponding sub-display can be obtained, for example, the frame of the sub-display may occupy 1 / 9 of the corresponding sub-display, which is only an example and does not limit the specific value of the proportion of the frame of the sub-display occupying the corresponding sub-display.

[0065] Optionally, the frames of the plurality of sub-displays in the image information can be identified by an OCR recognition algorithm to obtain the frame information of the sub-displays, which is only an example and does not limit the algorithm for identifying the frame of the sub-display.

[0066] As an optional implementation, based on the frame information of the sub-display, the picture of the sub-material information is cropped to obtain target material information, including: based on the proportion information of the frame size of the sub-display and the size of the sub-display, determining the cropping information of the sub-material information, wherein the cropping information is used to represent the pixel range of the sub-material information; and cropping the sub-material information according to the cropping information to obtain the target material information.

[0067] In this embodiment, after obtaining the frame information of the plurality of sub-displays included in the spliced display screen, since the frame information is used to indicate the proportional relationship between the frame size of the sub-display and the size of the sub-display, based on this, the cropping information of the sub-material information corresponding to the plurality of sub-displays can be determined according to the proportional relationship, wherein the cropping information is used to represent the pixel range of the sub-material information, and the pixel range is used to indicate the cropping proportion of the material information. Then, the sub-material information corresponding to each sub-display can be cropped according to the cropping information to obtain the target material information corresponding to each sub-display, so as to achieve the purpose of cropping the material information to be played into the target material information matched with the display area of the plurality of sub-displays, and further realize the technical effect of eliminating the influence of the frame on the picture proportion of the spliced display screen.

[0068] For example, after the proportion information that the frame of each sub-display occupies the corresponding sub-display is determined, the cutting information of the corresponding sub-material information of each sub-display can be determined according to the proportion information, wherein the cutting information is used to represent the pixel range of cutting the sub-material information, that is, the cutting proportion of cutting the sub-material information. For example, the frame size of the sub-display occupies 1 / 9 of the size of the sub-display. Based on this, in order to avoid the display screen from appearing a sense of fragmentation after the corresponding sub-display plays the corresponding sub-material information, the corresponding sub-material information of the corresponding sub-display can be cut according to the proportion information that the frame size of each sub-display occupies the size of the corresponding sub-display, to obtain the target material information after cutting. For example, if the frame of the sub-display is located below the corresponding sub-display and occupies 1 / 9 of the size of the corresponding sub-display, based on this, it can be determined that when the sub-material information to be displayed corresponding to the sub-display is cut, the pixel range occupying 1 / 9 of the sub-material information below the sub-material information can be cut, and then the target material information after cutting is obtained. Here, only an example is exemplified.

[0069] In this embodiment, after the cutting of the material information to be played is completed to obtain the target material information displayed in the sub-displays respectively, since the target material information displayed in the sub-displays is cut by some pixels, based on this, the cut target material information is spliced together, which is equivalent to a blank row and column divided by the cut pixels, the original picture after division, for example, Figure 3 is a schematic view of displaying the material information to be played in a spliced display screen according to an embodiment of the application, as shown in Figure 3 If the material information to be played is not cut according to the proportion information that the frame of each sub-display of the spliced display screen occupies the corresponding sub-display, the display screen will cause the picture played on the spliced display screen to appear a sense of fragmentation when the material information to be played is displayed on the spliced display screen. Figure 4 is a schematic view of displaying the target material information in a spliced display screen according to an embodiment of the application, as shown in Figure 4 Since the target material information is obtained by cutting the sub-material information to be displayed of each sub-display according to the proportion information that the frame of each sub-display occupies the corresponding sub-display, when the target material information is displayed in the corresponding sub-display, the picture displayed in the spliced display screen will not appear a sense of fragmentation, which achieves the purpose of eliminating the influence of the frame of the spliced display screen on the display picture proportion.

[0070] Optionally, when the target material information corresponding to the display area of the sub-display is determined from the material information to be played based on the image information, the material information can also be cut according to the frame size of the sub-display. This will be further introduced below.

[0071] As an optional implementation, in step S202, the target material information corresponding to the display area of each of the plurality of sub-displays is determined from the material information to be played based on the image information, including: extracting the spliced display screen image in the image information to obtain the frame size information of the plurality of sub-displays; and generating the target material information, wherein the target material information is obtained by cropping the material information according to the frame size information.

[0072] In this embodiment, after obtaining the image information of the spliced display screen collected by the machine vision method, the spliced display screen image in the image information can be extracted to obtain the frame size of the plurality of sub-displays, and the target material information obtained by cropping the material information according to the frame size can be obtained, so as to achieve the technical effect of eliminating the influence of the frame of the sub-display on the picture ratio of the spliced display screen.

[0073] Optionally, the cropping of the material information according to the frame size information can be to crop the content occupied by the frame of the sub-display in the material information, so as to achieve the technical effect of ensuring that the picture displayed on the spliced display screen is not deformed.

[0074] In this embodiment, the image information can further include identification information of the playing device, and when the target material information is sent to one or more playing devices connected with the plurality of sub-displays in step S203, the association between the position information of the sub-display on the spliced display screen and the identification information of the playing device can be realized, which will be further introduced below.

[0075] As an optional implementation, the method can further include: determining the position information of the plurality of sub-displays on the spliced display screen based on the image information; and in step S203, sending the target material information to one or more playing devices connected with the plurality of sub-displays, including: sending the target material information to one or more playing devices connected with the plurality of sub-displays based on the association between the position information and the identification information, wherein the association is used to represent the corresponding relationship between the display area of the sub-display and the playing device.
