[0032] The visual auxiliary screen matching method provided by the embodiments of the present application can be applied to a terminal device connected with multiple display screens, wherein the multiple display screens are in a preset space, and each display screen includes multiple cabinets.

[0033] Referring to Figure 1 An application scenario provided by the embodiments of the present application is shown in FIG. 1. As shown in FIG. 1, a terminal device 100 is connected with multiple display screens 110, and the multiple display screens 110 are in a preset space. Figure 1As shown, the terminal device can be connected with the input source and multiple display screens in a preset space, and the terminal device can include a host computer and a display control device. The visual auxiliary screen matching method provided by the embodiment of the application can obtain the space data of the multiple display screens by operating the host computer, and generate a three-dimensional real scene model including the multiple display screens by using a VR display module in the host computer according to the obtained space data, and display the three-dimensional real scene model in a visual screen matching interface. After the three-dimensional real scene model (for example, a VR real scene model) of the multiple display screens is displayed in the visual screen matching interface of the terminal device, since the multiple display screens are in the same preset space and the display screens are composed of multiple cabinets, the user can first select a target display screen in the three-dimensional real scene model, and configure the cabinet models constituting the target display screen, that is, configure the topological relationship between the cabinets. Then, the terminal device can obtain configuration information including the topological relationship between the multiple cabinets in response to the configuration of the cabinet models of the target display screen (for example, the user's configuration of the cabinet models of the target display screen). The host computer and the display control device can send the configuration information to the target display screen on site, so as to adjust the topological relationship between the multiple cabinets constituting the target display screen on site, thereby achieving the purpose of assisting the target display screen in screen matching.

[0034] The host computer can be a screen matching software on the terminal device.

[0035] The terminal device generally refers to various terminal devices such as a personal computer (PC), a tablet computer, a personal digital assistant (PDA), a mobile internet device (MID), and the like, which can run the visual auxiliary screen matching method program, and the embodiment of the application is not limited thereto.

[0036] It should be understood that Figure 1 To realize one application scenario of the visual auxiliary screen matching method provided by the embodiment of the application, the hardware architecture of the application scenario is only an example, and the visual auxiliary screen matching method provided by the embodiment of the application can also be realized by other hardware architectures, and the application is not limited thereto.

[0037] The visual auxiliary screen matching method provided by the embodiment of the application is implemented as follows:

[0038] The input source display sub-region is arranged in the screen matching software. The screen matching software can acquire spatial data of a plurality of display screens scanned by the 3D scanning software, and then generate a VR real scene model including the plurality of display screens by using a VR display module in the screen matching software according to the spatial data, and display the VR real scene model in a screen matching interface of the screen matching software for user configuration. When the user configures, the user can combine the input source with the VR real scene model to obtain a VR real scene model of the plurality of display screens containing images. The user can configure a plurality of box models of a target display screen selected in the VR real scene model according to a desired display effect, and then obtain configuration information (such as position, rotation angle, and wiring relationship, etc.) of a plurality of boxes of the target display screen constructed on site according to the configuration of each box model, determine the topological relationship between the plurality of boxes constituting the target display screen, and send the configuration information containing the topological relationship between the plurality of boxes to the display screen control device, so that the display screen control device adjusts the topological relationship between the plurality of boxes of the target display screen according to the received configuration information, and realizes visual auxiliary screen matching through the VR real scene model of the plurality of display screens displayed in the screen matching interface.

[0039] The following will be based on the above Figure 1 The application examples provide a visual auxiliary screen matching method. The application examples provide a visual auxiliary screen matching method.

[0040] It should be understood that the size of the serial number of each step in the embodiment does not mean the order of execution, and the execution order of each process should be determined according to its function and inherent logic, and should not constitute any limitation on the implementation process of the application examples.

[0041] Referring to Figure 2 , a flowchart of a visual auxiliary screen matching method provided by an application example is shown. As Figure 2 indicated, the visual auxiliary screen matching method can include the following steps:

[0042] Step 201, acquiring spatial data of a plurality of display screens.

[0043] It should be noted that the visual auxiliary screen matching method of the application examples can be executed by the visual auxiliary screen matching device of the application examples. The visual auxiliary screen matching device of the application examples can be configured in a terminal device connected to a plurality of display screens to execute the visual auxiliary screen matching method of the application examples. For example, the device of the application examples can be configured in the host computer software of the terminal device, and the application examples are not limited thereto.

[0044] The multiple display screens can be multiple display screens in a same preset space. It should be noted that the multiple display screens in the same preset space can have display surfaces in different two-dimensional planes, for example, the multiple display screens are respectively a sky screen and a ground screen in the preset space. The display surfaces of the multiple display screens are in different two-dimensional planes, so that the method of the embodiment of the present application is more comprehensive.

[0045] The space data can be original data obtained by using a three-dimensional scanning device to scan. For example, a three-dimensional scanner obtains shape and spatial position data of a box of each display screen by scanning the multiple display screens in the preset space. It should be noted that the space data, also referred to as geometric data, is used to represent information such as position, shape, size distribution, and the like of an object. In the embodiment of the present application, the space data of the display screen can include shape data and / or position data of the box constituting the display screen.

[0046] In the embodiment of the present application, the multiple display screens can be scanned by using 3D scanning software. Since each display screen includes multiple boxes, shape data and / or position data of the multiple boxes constituting the display screen can be generated. Then, the terminal device can obtain the space data by data transmission. That is, the terminal device automatically obtains the shape data and / or position data of the multiple boxes in each display screen in the 3D scanning software by real-time scanning of the 3D scanning software when new scanning data is added in the 3D scanning software. Alternatively, the 3D scanning software imports the scanning data to the terminal device, that is, the terminal device does not need to monitor the 3D scanning software in real time, and only needs to select whether to respond when the 3D scanning software imports the scanning data to the terminal device. The position data can include three-dimensional spatial coordinates.

[0047] As a possible implementation manner, the terminal device can automatically obtain three-dimensional spatial coordinates of the multiple boxes in each display screen scanned by the three-dimensional scanning device. For example, the 3D scanning software scans the multiple display screens in the preset space, stores the obtained data in the 3D scanning software, and the terminal device monitors the 3D scanning software in real time. After detecting that new scanning data is stored in the 3D scanning software, the terminal device automatically extracts the new scanning data to the screen matching software of the terminal device, so that the screen matching software generates a corresponding three-dimensional real scene model according to the obtained data.

[0048] As a possible implementation manner, the spatial data of the plurality of boxes in each display screen imported by the scanning device can also be received in response to a data import instruction of the scanning device. For example, the plurality of display screens are scanned by the 3D scanning software, and the scanned data is stored in the 3D scanning software. After detecting that new scanning data is stored in the 3D scanning software, the 3D scanning software can send a data import instruction to the terminal device. After receiving the response of the terminal device, the scanning data stored in the 3D scanning software is imported into the screen matching software of the terminal device. The terminal device receives the scanning data imported by the 3D scanning software, so that the screen matching software generates a corresponding three-dimensional real scene model according to the obtained data.

[0049] In step 202, a three-dimensional real scene model containing a plurality of display screens is generated according to the spatial data, and is displayed in a visual screen matching interface.

[0050] The plurality of display screens can be display screens in the same preset space. It should be noted that the display surfaces of the plurality of display screens can be in the same two-dimensional plane, or can be in different two-dimensional planes. The position and orientation of the display surfaces of the plurality of display screens are not limited in the present application.

[0051] The three-dimensional real scene model can be a VR real scene model. It should be noted that in the process of generating a VR real scene model, three-dimensional data of an actual environment is first obtained, and then a corresponding real scene model is established according to the needs of the application. The corresponding real scene model can be established according to the needs of the application by embedding a VR display module in the screen matching software.

[0052] The visual screen matching interface can be a screen matching interface of the screen matching software. It should be noted that the visual screen matching interface includes a VR display interface, which can be displayed by the VR display module. The visual screen matching interface also includes at least an input source display sub-region. The terminal device can obtain the input sources of the plurality of display screens and display the input sources in the input source display sub-region. When the three-dimensional real scene model displayed in the VR display interface is configured, the input sources can be displayed in each display screen model in the three-dimensional real scene model, so as to preview the effect diagram of the plurality of display screens displaying corresponding input sources in the preset space.

[0053] As a possible implementation manner, after the spatial data is acquired, the screen matching software in the terminal device can construct a three-dimensional model of the plurality of display screens according to the spatial data. Since each display screen is composed of a plurality of cabinets, the three-dimensional model of each display screen includes three-dimensional models of the plurality of cabinets. Since the spatial data includes position data of the plurality of cabinets, according to the position data and the three-dimensional models of the plurality of cabinets constituting the display screen, the three-dimensional models of the plurality of cabinets can be placed according to the actual positions to generate a three-dimensional model of the display screen same as the actual environment position. Then, the same operation is performed on the cabinets in the plurality of display screens to generate a plurality of three-dimensional models of the display screens same as the actual environment position. According to the plurality of three-dimensional models of the display screens same as the actual environment position, a three-dimensional real scene model of the plurality of display screens same as the actual environment position can be finally generated.

[0054] As a possible implementation manner, a specific mark can also be arranged on the surface of the display screen in the actual environment on site, for example, a specific mark is pasted around the display screen, that is, each display screen surface has a unique corresponding mark. When the three-dimensional real scene model of the plurality of display screens same as the actual environment position is generated according to the three-dimensional models of the plurality of display screens, the following manner can be adopted:

[0055] identifying the mark of each display screen;

[0056] automatically marking the three-dimensional models of the plurality of display screens according to the identified mark of each display screen to obtain the mark of the three-dimensional model of each display screen;

[0057] determining the positions of the three-dimensional models of the plurality of display screens in the three-dimensional real scene model according to the mark of the three-dimensional model of each display screen, and generating the three-dimensional real scene model corresponding to the preset space.

[0058] It should be understood that since each display screen has a unique mark, when the three-dimensional real scene model is displayed in the visual screen matching interface, each display screen in the three-dimensional real scene model also has a mark based on the mark of the display screen. The user can determine the correspondence between the three-dimensional model of the display screen and the display screen on site according to the mark.

[0059] It should be understood that since each display screen has a unique mark, when the three-dimensional real scene model is displayed in the visual screen matching interface, each display screen in the three-dimensional real scene model also has a mark based on the mark of the display screen. The user can determine the correspondence between the three-dimensional model of the display screen and the display screen on site according to the mark.

[0060] In step 203, in response to the cabinet model configuration of the target display screen in the three-dimensional real scene model, the topological relationship between the plurality of cabinets of the target display screen is determined to assist the target display screen in screen matching.

[0061] The box model configuration of the target display screen in the three-dimensional real scene model can refer to that the user edits the three-dimensional real scene model displayed in the visual screen matching interface. For example, by clicking any three-dimensional model corresponding to a display screen in the three-dimensional real scene model, the position, angle and wiring relationship of the three-dimensional model corresponding to the box in the display screen can be edited. In response to the configuration, the screen matching software can pop up an interface for viewing and editing the topologies of the multiple box models included in the three-dimensional model when the user clicks any three-dimensional model corresponding to a display screen. After editing is completed, the three-dimensional real scene model will be changed according to the user's operation, which facilitates the user to intuitively preview the topologies between the boxes of each display screen in the entire preset space without switching two-dimensional planes and editing in each two-dimensional plane, and can improve the efficiency of screen matching.

[0062] As a possible implementation manner, the target display screen can be selected in the visual interface in response to the configuration instruction, and each box model constituting the target display screen is configured. The position, angle and wiring of each box corresponding three-dimensional model are configured, and the position relationship, angle relationship and wiring relationship between the three-dimensional models corresponding to each box are determined. Then, the topological relationship between each box is determined according to the position relationship, angle relationship and wiring relationship between the three-dimensional models corresponding to each box.

[0063] It should be understood that the user can select any display screen as the target display screen, and can determine the topological relationship between each box constituting the target display screen based on the above operation, and then the topological relationship between the multiple boxes of each display screen in the preset space can be determined.

[0064] The topological relationship can include the position relationship, the angle relationship and the wiring relationship.

[0065] The box model can refer to the three-dimensional model corresponding to the box.

[0066] For example, after the three-dimensional real scene model including the plurality of display screens is displayed on the screen matching interface, a user can click the three-dimensional model corresponding to one of the display screens, and the display screen is the target display screen. After the topology editing interface is popped up, the position, angle, and wiring of the three-dimensional model corresponding to each cabinet of the target display screen can be configured. The terminal device adjusts the topology structure of the three-dimensional model corresponding to each cabinet in the three-dimensional real scene model in response to the configuration of the user, and displays the topology structure. The position relationship, angle relationship, and wiring relationship between the three-dimensional models corresponding to each cabinet can be determined according to the above method. Then, because the three-dimensional real scene model is completely corresponding to the plurality of display screens in the preset space, the topology relationship between the cabinets can be determined according to the position relationship, angle relationship, and wiring relationship between the three-dimensional models corresponding to each cabinet. In this way, the topology relationship between each cabinet in the target display screen is determined. The user can perform the same operation on the plurality of display screens. Then, the terminal device can configure the plurality of display screens in the preset space according to the topology relationship between the cabinets corresponding to each display screen.

[0067] As a possible implementation, after the topology relationship between the cabinets corresponding to each display screen is determined, if it is desired to adjust the topology structure of each display screen in the field, configuration information including the topology relationship can be generated according to the topology relationship between the cabinets of each display screen. Then, the configuration information is sent to a control device (i.e., a display screen control device) that controls the display screen, so that each cabinet of each display screen adjusts its own configuration to complete the adjustment of the topology structure of the plurality of display screens in the preset space. After the adjustment, the corresponding input source is displayed, and the screen matching operation of each display screen can be completed.

[0068] After the spatial data of the plurality of display screens is obtained, the embodiment of the present application can generate a three-dimensional real scene model including the plurality of display screens according to the spatial data, and display the three-dimensional real scene model in the visual screen matching interface. Then, the topology relationship between the plurality of cabinets of the target display screen is determined in response to the cabinet model configuration of the target display screen in the three-dimensional real scene model, to assist the target display screen in screen matching. The above scheme can display the generated three-dimensional real scene model in the visual screen matching interface, so that the user can intuitively operate the generated three-dimensional real scene model, and the problem of difficult topology relationship configuration caused by complex operation is solved.

[0069] Referring to Figure 3 , a flowchart of a visual auxiliary screen matching method provided by an embodiment of the present application is shown. As Figure 3 indicated, the visual auxiliary screen matching method can include the following steps:

[0070] In step 301, spatial data of a plurality of display screens and environmental spatial data of an environment surrounding the plurality of display screens in a preset space are obtained.

[0071] The preset space can be a three-dimensional space in which the plurality of display screens are located. It should be noted that if the plurality of display screens are installed outdoors, the range of the preset space can be freely set, and the present application does not limit this. If the plurality of display screens are installed indoors, the range of the preset space should be the range of the space constituted by the enclosed indoor space, because in the enclosed indoor space, the adjustment range of the cabinet topology structure of the plurality of display screens is limited, and therefore the range of the preset space needs to be set as the range of the space constituted by the enclosed indoor space.

[0072] The environmental space data can be space data of an environment surrounding the plurality of display screens, such as space data of obstacles in the surrounding environment.

[0073] As a possible implementation manner, the method for acquiring the environmental space data of the environment surrounding the plurality of display screens is the same as the method for acquiring the space data of the plurality of display screens in Embodiment 1, and details are not described herein again. For details, refer to the method for acquiring the space data of the plurality of display screens in Embodiment 1.

[0074] For example, in Embodiment 1, the space data of the plurality of display screens is acquired by using 3D scanning software to scan the plurality of display screens, to generate shape data and position data of the cabinet of the plurality of display screens, and then the terminal device can acquire the space data by data transmission. In this embodiment, the environmental space data is acquired by using 3D scanning software to scan the entire preset space, and other objects except the plurality of display screens are taken as the environmental space data of the environment surrounding the plurality of display screens.

[0075] It should be understood that the above examples are only exemplary and cannot be regarded as a limitation of the present application. In actual use, the method for acquiring the space data of the plurality of display screens in Embodiment 1 can be referred to.

[0076] In step 302, a three-dimensional model of the plurality of display screens and the surrounding environment is constructed according to the space data of the plurality of display screens and the environmental space data of the environment surrounding the plurality of display screens.

[0077] In this embodiment, the space data of the plurality of display screens includes shape data and / or position data of the cabinet constituting each display screen. After the terminal device acquires the space data of the plurality of display screens and the environmental space data of the environment surrounding the plurality of display screens, the screen matching software in the terminal device can construct a three-dimensional model of the plurality of display screens and the environment surrounding the plurality of display screens according to the space data of the plurality of display screens and the environmental space data of the environment surrounding the plurality of display screens, to completely restore the actual scene corresponding to the preset space. For example, a table is placed around the display screen, and therefore a three-dimensional model of the table needs to be constructed. The display screen is installed on a wall, and therefore a three-dimensional model of the wall needs to be constructed.

[0078] In step 303, a three-dimensional real scene model corresponding to the preset space is generated according to the plurality of display screens and the three-dimensional model of the surrounding environment.

[0079] It should be noted that in the process of generating the VR real scene model, three-dimensional data of the actual environment is first acquired, and then a corresponding real scene model is established according to the application requirement. The corresponding real scene model can be established according to the application requirement by embedding a VR display module in the screen matching software.

[0080] As a possible implementation manner, after obtaining the three-dimensional models of the plurality of display screens and the surrounding environment, the actual positions of each three-dimensional model in the preset space can be determined according to the spatial data of the display screens and the environmental spatial data of the surrounding environment, the objects of the plurality of display screens and the surrounding environment are placed according to the obtained actual positions, and finally a three-dimensional real scene model of the preset space which is the same as the actual scene can be generated.

[0081] As a possible implementation manner, a specific mark can also be set on the surface of the display screen in the actual scene, for example, a specific mark is pasted around the display screen, that is, each display screen surface has a unique corresponding mark, and the following manner can be used to generate the three-dimensional real scene model corresponding to the preset space:

[0082] identifying the mark of each display screen;

[0083] automatically marking the three-dimensional models of the plurality of display screens according to the identified mark of each display screen to obtain the mark of the three-dimensional model of each display screen;

[0084] determining the positions of the three-dimensional models of the plurality of display screens in the three-dimensional real scene model according to the mark of the three-dimensional model of each display screen, and generating the three-dimensional real scene model corresponding to the preset space.

[0085] It should be understood that the positions of the three-dimensional models of the plurality of display screens in the three-dimensional real scene model can be determined according to the mark of each three-dimensional model, and the positions of the objects existing around the plurality of display screens can be obtained according to the environmental spatial data, and the mark on the display screen can mainly facilitate the user to determine the corresponding relationship between the three-dimensional model of the display screen and the on-site display screen box according to the mark.
