Description

Technical Field

[0001] The present invention relates to the field of image display, and in particular to a method, device, equipment and medium for splicing images on a display screen. Background Art

[0002] In today's era of rapid development of information technology, LED display screens, as an important information display tool, are highly favored for their excellent display effects and wide applicability. Usually, LED display screens are assembled with cabinets or modules as the basic components. However, in general, the parameters preset at the factory for LED display screens often have limitations. They can only realize the independent lighting of a single module or cabinet, and cannot directly achieve seamless splicing and coordinated display of the entire display screen. This leads to the problem of how to integrate the scattered modules and cabinets into a complete, unified and coordinated display screen after the assembly of the LED display screen is completed on site.

[0003] To solve this problem, the existing common processing method is to rely on professional technicians to follow the detailed drawings prepared in advance, or to check the specific wiring positions of each module or display screen one by one after the display screen is assembled, and then set these position information to the control system one by one. Obviously, this existing splicing solution has many significant defects and shortcomings. First, the solution places high demands on the professional knowledge and skill level of technicians. Second, when facing large or super-large LED display screen projects, due to the large number of modules or cabinets involved, technicians need to spend a lot of time and energy in the process of confirming the wiring position. Third, in the process of workers actually assembling the display screen, they must strictly follow the pre-designed drawings for wiring operations. This means that once any slight deviation or error occurs during the assembly process, it may cause the splicing of the entire display screen to fail or display abnormalities.

[0028] Embodiment 1

[0029] Figure 1 A flow chart of a display screen image splicing method provided in Embodiment 1 of the present invention. This embodiment is applicable to the situation of performing image splicing on multi-box display screens. The method can be executed by a display screen image splicing device. The display screen image splicing device can be implemented in the form of hardware and / or software. The display screen image splicing device can be configured in a terminal or server with a display screen image splicing function.

[0030] like Figure 1 As shown, the method includes:

[0031] S110 , in response to a module splicing instruction from a user, acquiring the module position of each target module in the target display screen to obtain the position of each module.

[0032] Among them, the target display screen is composed of at least one target box, and the target box is composed of at least one target module; further, the module is the smallest display unit of the display screen, such as a common LED module, which is composed of multiple light-emitting diodes and related circuits, and the box is a larger display module composed of multiple modules, such as a rectangular box containing several row and column modules.

[0033] Specifically, the target modules constituting the same target box establish a communication connection with the same receiving card through a flat cable, and the receiving card establishes a communication connection with a sending card through a target network port; it should be noted that in the actual connection method, the target modules constituting the same target box establish a communication connection with the same receiving card through a flat cable, and the flat cable refers to a soft flat cable for realizing signal transmission, and a receiving card is a hardware device for receiving and processing display signals, such as a common LED display receiving card, and the receiving card establishes a communication connection with a sending card through the target network port, and the sending card is responsible for sending the image data to the receiving card, and the network port is a network interface for realizing data transmission.

[0034] Among them, in response to the user's module splicing instruction, the module position of each target module in the target display screen is obtained to obtain each module position, including: in response to the user's module splicing instruction, the first position information of each target module is obtained respectively, wherein the first position information is the serial port number of the target module connected to the receiving card through the cable; after obtaining the first position information of the target module, the cascade serial number of each target module is obtained respectively as the second position information of the target module; based on the first position information and the second position information, a module position matching the target module is generated.

[0035] Exemplarily, in response to the user's module splicing instruction, the module position of each target module in the target display screen is obtained to obtain the position of each module, which includes the following steps: First, in response to the user's module splicing instruction, the first position information of each target module is obtained respectively. The first position information here refers to the serial port number of the target module connected to the receiving card through the cable, such as serial port number 1, serial port number 2, etc. After successfully obtaining the first position information of the target module, the cascade sequence number of each target module is then obtained respectively, and used as the second position information of the target module. For example, the cascade sequence number of a module is 3, indicating its sequential position in the cascade. Finally, based on the first position information and the second position information obtained above, a module position matching the target module is generated.

[0036] Optionally, the method for obtaining the cascade number is as follows: during the process of each target module leaving the factory, the developer pre-sets a unique identification code for each module; when the module is connected to the receiving card, the control system automatically assigns cascade numbers to the modules according to the order of connection, for example, the first connected module is assigned number 1, the second connected module is assigned number 2, and so on; or each module is assigned an initial code during production, and when the module establishes a communication connection with the receiving card, the receiving card sends an inquiry signal to the module, and the module replies with its initial code. The receiving card assigns cascade numbers to the modules according to the order of the received initial codes.

[0037] Relevant personnel in this field should understand that since the method of obtaining the receiving card serial port number and the cascade number of the target module is a mature existing technology, the method of obtaining the cascade number provided in this embodiment is an example of some common methods of obtaining cascade number. In actual applications, different methods may be adopted according to specific hardware and software designs, and this embodiment does not limit this.

[0038] S120 . In response to the user's cabinet splicing instruction, the position of each target cabinet is acquired to obtain the position of each cabinet.

[0039] Among them, in response to the user's cabinet splicing instruction, the position of each target cabinet is acquired to obtain the position of each cabinet, including: in response to the user's cabinet splicing instruction, third position information matching the target cabinet is respectively acquired, and the third position information is the receiving card serial number of the target receiving card that is communicatively connected to the target cabinet; after acquiring the third position information, the sending card serial number of the sending card that is communicatively connected to the target receiving card is acquired as the fourth position information; the network port serial number of the target network port is acquired as the fifth position information, and a cabinet position matching the target cabinet is generated based on the third position information, the fourth position information and the fifth position information.

[0040] Specifically, in response to the user's cabinet splicing instruction, the position of each target cabinet is obtained to obtain the position of each cabinet, which includes the following steps: First, in response to the user's cabinet splicing instruction, the third position information matching the target cabinet is obtained respectively. The third position information here refers to the receiving card serial number of the target receiving card that has a communication connection with the target cabinet, for example, the receiving card serial number may be 1, 2, 3, etc. After successfully obtaining the third position information, the sending card serial number of the sending card that has a communication connection with the target receiving card is then obtained, and it is used as the fourth position information, for example, the sending card serial number may be A, B, C, etc. Then, the network port serial number of the target network port is obtained as the fifth position information, and the network port serial number may be 01, 02, 03, etc. Finally, based on the obtained third position information, fourth position information and fifth position information, a cabinet position matching the target cabinet is generated.

[0041] It should be noted that in actual applications, the implementation rules of the receiving card serial number, the sending card serial number and the network port serial number can be numbers, letters or a combination of numbers and letters, which can be set by the developer according to the actual implementation scenario. This embodiment does not limit this.

[0042] S130, obtaining a picture to be displayed, dividing the picture to be displayed into target picture blocks respectively matching the target modules according to the positions of the modules and the boxes, and displaying the target picture blocks matching the target modules through the target modules, so as to splice the target picture blocks to obtain a target image matching the display screen image.

[0043] The technical solution of the embodiment of the present invention first responds to the module splicing instruction of the user to obtain the module position of each target module in the target display screen to obtain the position of each module, then responds to the cabinet splicing instruction of the user to obtain the position of each target cabinet to obtain the position of each cabinet, and finally obtains the picture to be displayed, divides the picture to be displayed into target blocks that match each target module respectively according to the position of each module and the position of each cabinet, and displays the target blocks that match the target module through the target module, so as to splice each target block to obtain a target image that matches the display screen image, thereby realizing image splicing of a multi-cabinet display screen when displaying images, improving the efficiency of image splicing work, and reducing the manpower consumption of display screen image splicing work.

[0044] Embodiment 2

[0045] Figure 2 A flow chart of a display screen image splicing method provided in the second embodiment of the present invention. This embodiment is refined based on the above embodiment. In this embodiment, a method of dividing the image to be displayed into target blocks that match each target module according to the position of each module and the position of each box is specifically refined.

[0046] like Figure 2 As shown, the method includes:

[0047] S210 , in response to a module splicing instruction from a user, acquiring the module position of each target module in the target display screen to obtain the position of each module.

[0048] S220 . In response to the user's cabinet splicing instruction, the position of each target cabinet is acquired to obtain the position of each cabinet.

[0049] S230, calculating the display area of ​​each target box, and dividing the to-be-displayed picture based on the display area and the box position of each target box to obtain target pictures respectively matching each target box.

[0050] Specifically, the display area of ​​each target box is calculated, and based on the area of ​​each display area and the box position of each target box, the image to be displayed is segmented to obtain each target screen that matches each target box, including: displaying the box position that matches the target box through each target box; using an image acquisition device to acquire the current image of the target display screen, and processing the current image through a preset image processing system to obtain a box segmentation result that matches the target screen, wherein the box segmentation result includes a display area and a zone number corresponding to each target box, and the zone number is the same as the box position of the target box; calculating the zone area of ​​each display area to obtain the display area of ​​each target box; based on the size ratio of each display area area of ​​each target box, the image to be displayed is rectangularly segmented to obtain screens to be displayed that match each target box; and each screen to be displayed and the zone number that matches the screen to be displayed are aggregated to obtain each target screen.

[0051] Among them, the image acquisition device can be a digital camera, a scanner or an industrial camera, etc., which is used to obtain image information of the display screen. The image processing system is a software system that includes a series of image processing algorithms and tools, such as Photoshop or a program specially developed for display screen image processing.

[0052] Exemplarily, the display area of ​​each target box is calculated, and based on the display area and the box position of each target box, the image to be displayed is segmented to obtain each target screen that matches each target box. The specific steps are as follows: First, each target box displays the box position that matches itself, for example, by indicating the position information of the box through the indicator light or display screen on the box. Then, the current picture of the target display screen is collected using an image acquisition device, such as using a mobile phone camera to shoot the entire display screen. Then, the current picture is processed by a preset image processing system to obtain a box segmentation result that matches the target screen, where the box segmentation result includes the display area and area number corresponding to each target box, and the area number is the same as the box position of the target box. For example, the image processing system divides the display screen into different areas by identifying the boundaries and features between the boxes, and assigns a unique number to each area. After that, the area area of ​​each display area is calculated respectively, so as to obtain the display area area of ​​each target box. For example, the length and width of each area are accurately measured through an image analysis algorithm, and then the area is calculated. Then, based on the size ratio of each display area of ​​each target box, the image to be displayed is divided into rectangles to obtain the images to be displayed that match each target box. For example, if a box is located in the upper left corner of the display screen, and the display area accounts for 20% of the total display area, then 20% of the upper left corner of the image to be displayed is correspondingly divided as its image to be displayed. Finally, the images to be displayed and the area numbers matching the images to be displayed are aggregated to obtain the target images, so that each target box can accurately obtain the corresponding image content that is adapted to its display area.

[0053] S240, respectively calculating the display area of ​​each target module in each target box, and dividing each target screen based on the display area and the module position of each target module to obtain target picture blocks respectively matching each target module.

[0054] The method comprises: obtaining target images matching each target box by using the area number of the target image and the box position of each target box, and displaying the module position matching the target module by using the target module; acquiring the current box image of the target box by using an image acquisition device, and processing the current box image by using a preset image processing system to obtain a module segmentation result matching the target box, wherein the module segmentation result includes a display area and a module number corresponding to each target module, and the module number is the same as the module position of the target module; calculating the area area of ​​each display area to obtain the module area area of ​​each target module; performing rectangular segmentation on the target image based on the size ratio of each module area area of ​​each target module to obtain the to-be-displayed picture blocks matching each target module; and binding each to-be-displayed picture with the module number matching the to-be-displayed picture to obtain the target picture blocks matching each target module.

[0055] Exemplarily, the display area of ​​each target module in each target box is calculated respectively, and based on the display area and the module position of each target module, each target screen is segmented to obtain each target picture block that matches each target module. The specific process includes: first, the target screen that matches each target box is accurately obtained by the area number of the target screen and the box position of each target box, and the module position that matches itself is displayed by the target module, for example, the position information is clearly identified by a specific indicator light or a small display screen on the module. Then, the current box image of the target box is collected using an image acquisition device, for example, an industrial camera with ultra-high pixels is used to clearly shoot the target box. Then, the current box image is processed by a preset image processing system to obtain a module segmentation result that matches the target box. This module segmentation result covers the display area and module number corresponding to each target module, and the module number is the same as the module position of the target module. For example, the image processing system uses image recognition and analysis algorithms to accurately identify the boundaries and features between modules, divide the box display area into different module areas, and assign numbers to each module. After that, the area of ​​each display area is calculated respectively, so as to obtain the module area area of ​​each target module. For example, by using image analysis and calculation methods, the length and width of each module display area are measured, and then its area is accurately calculated. Then, based on the size ratio of each module area of ​​each target module, the target screen is divided into rectangular blocks to obtain the to-be-displayed picture blocks that match each target module. For example, if the module area of ​​a target module accounts for 15% of the display area of ​​the box to which it belongs, then 15% of the part is divided from the corresponding position of the target screen as its to-be-displayed picture blocks. Finally, each to-be-displayed picture block is bound to the module number that matches the to-be-displayed picture block, so as to obtain each target picture block that matches each target module. In this way, it can be ensured that each target module can obtain the picture content that is adapted to its display area.

[0056] It should be noted that in this embodiment, since the area of ​​each display area can be automatically calculated using image analysis and calculation methods, in order to maintain the accuracy of the results, the display area of ​​each target box and the display area corresponding to the target module in this embodiment are all rectangular. Based on the above definition, the image segmentation algorithm, semantic segmentation model and target detection model can be used to automatically calculate the area of ​​each display area, saving human resources.

[0057] S250 , displaying the target picture blocks that match the target module through the target module, so as to splice the target picture blocks to obtain a target image that matches the display screen image.

[0058] The technical solution of the embodiment of the present invention first responds to the module splicing instruction of the user, obtains the module position of each target module in the target display screen, and obtains the position of each module; then responds to the cabinet splicing instruction of the user, obtains the position of each target cabinet, and then obtains the picture to be displayed, calculates the display area of ​​each target cabinet, and divides the picture to be displayed based on the display area area and the cabinet position of each target cabinet to obtain each target screen that matches each target cabinet respectively; then calculates the display area area of ​​each target module in each target cabinet respectively, and divides each target screen based on the display area area and the module position of each target module to obtain each target picture block that matches each target module respectively; finally, the target picture block that matches the target module is displayed through the target module, so as to splice each target picture block to obtain a target image that matches the display screen image, thereby realizing image splicing of a multi-cabinet display screen when displaying images, improving the efficiency of image splicing work, and reducing the manpower consumption of display screen image splicing work.
