Description

[0002] LED screens, with their high brightness, high contrast, rich colors, and flexible splicing capabilities, occupy an important position in many fields such as advertising media, stage performances, live sports broadcasts, and commercial displays. Their splicing display effect directly impacts the viewer's visual experience, especially in scenarios with stringent visual requirements such as large-scale events and high-end commercial displays, where the uniformity of splicing seams and color consistency become key indicators for measuring screen quality.
[0003] When reassembling an LED screen, the corrected seam repair often fails to maintain its effect. This is because the spacing between LED modules is difficult to perfectly match the previous assembly, necessitating re-seaming. Traditionally, to improve the seam repair, a tripod is used to fix the camera in a suitable position. A computer is then connected to the camera and LED display, specialized software is installed, and the camera's aperture and focus are adjusted. A photo is taken, and the LED screen is then re-seamed based on the photograph.

[0038] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.
[0039] This invention applies to scenarios requiring re-grouting of calibrated and repaired LED screens. For example, LED screens calibrated and repaired at the factory often need to be reassembled after being transported to the customer's site due to changes in installation conditions, spatial layout, and customer requirements. Another example is rental LED screens, which frequently move between different customers and locations, requiring reassembly each time. Because of differences in installation environment and splicing requirements at different sites, module spacing inevitably changes, making it difficult to maintain a stable grouting effect. Therefore, grouting needs to be performed during reassembly of the LED screen. Traditional camera-based grouting procedures include: First, using a tripod to fix the camera in a suitable position to ensure shooting stability. Second, connecting the computer to the camera and display screen and installing specialized software. Third, adjusting the camera's aperture and blur (focus) to capture images of the LED screen, and then performing grouting on the captured images. Using a tripod to stabilize the camera not only requires time to adjust parameters such as height and angle, but also presents challenges in finding suitable placement locations in space-constrained environments, increasing the complexity and time cost of camera retouching. Furthermore, connecting the computer to the camera and monitor can lead to interface incompatibility, wiring faults, and other issues, requiring significant time for troubleshooting and resolution, further extending retouching time. Moreover, adjusting the camera focus requires operators to possess certain photographic knowledge and experience to accurately adjust the camera to the optimal shooting state. Improper adjustment results in poor image quality, directly impacting subsequent retouching results and potentially leading to retouching failure, necessitating reshooting and retouching, thus further reducing efficiency. In addition, traditional camera retouching methods are highly dependent on hardware equipment such as the camera, tripod, and computer. If this hardware malfunctions or is damaged, retouching cannot be performed. Moreover, in certain environments, such as harsh outdoor weather conditions or locations without a stable power supply, the normal operation of hardware is limited, making retouching difficult to carry out. To address the shortcomings of the existing technology, this application provides a method for repairing seams in an LED screen, such as... Figure 1 As shown, the method includes:
[0040] Step 101: Use LED screen management software to read the initial gap parameters of the LED screen.
[0041] Specifically, in this embodiment of the invention, the LED screen management software is LED Genie. The initial gap parameters of the LED screen include: the original correction coefficient of the LED screen and the module width and height. The original correction coefficient of the LED screen is data recorded during the factory or initial calibration, reflecting the pixel correction state of the screen before gap correction processing. An LED screen is typically composed of multiple modules spliced together, each module having its fixed dimensions. The module width and height refer to the width and height of a single module within the LED screen.
[0042] Step 102: Determine the removal and repair coefficient of the LED screen based on the initial gap parameters.
[0043] Specifically, after the LED screen undergoes seam repair, its pixel correction state changes, resulting in an inconsistency between the screen display and its original state. When reassembling the LED screens, seam repair or adjustment of the screen display is required, necessitating restoring the screen to its unrepaired state. This application, by determining a seam removal coefficient, avoids the tedious process of re-seaming using traditional cameras, significantly improving seam repair efficiency.
[0044] Step 103: Use the removal seam repair coefficient to restore the LED screen to its unrepaired state.
[0045] Specifically, by applying the calculated removal seam repair coefficient, the repaired LED screen is restored to its unrepaired state, that is, the original seam repair effect is stripped away.
[0046] Step 104: Repair the grout lines on the LED screen in its unrepaired state.
[0047] Specifically, after the screen is restored to its unrepaired state, the LED screen is repaired again as needed.
[0048] The method for repairing gaps in LED screens provided in this application reads the initial gap parameters of the LED screen through LED screen management software, determines the removal gap repair coefficient of the LED screen based on the initial gap parameters, and then restores the LED screen to the unrepaired state based on the removal gap repair coefficient. This method enables direct operation via mobile terminal (such as mobile phone) without relying on professional cameras or complex equipment, achieving the goal of one-click restoration to the unrepaired state and greatly improving gap repair efficiency.
[0049] Furthermore, the following section details how to determine the removal and repair coefficient of the LED screen based on the initial gap parameters, specifically including the following solutions:
[0050] First, the gap coordinates of the LED screen are determined based on the module width and height. Second, the average value of the correction coefficients in the gap area and the average value of the correction coefficients in the non-gap area are determined based on the original correction coefficients of the LED screen and the gap coordinates of the LED screen. Finally, the removal and repair coefficients are determined based on the average value of the correction coefficients in the gap area and the average value of the correction coefficients in the non-gap area.
[0051] Specifically, the module's width and height are used to locate the gap positions, i.e., coordinates (x, y). For example, assuming the LED screen module's width and height are 192*108, the first vertical gap's coordinates are at x=192, and the second vertical gap's coordinates are at x=384. The location of horizontal gaps is similar to that of vertical gaps and will not be elaborated here. Furthermore, while determining the gap coordinates based on the module's width and height, this application can also distinguish between gap areas and non-gap areas of the LED screen.
[0052] The correction coefficient reflects the degree of brightness or color adjustment of each pixel on the screen. By calculating the average value, we can understand the overall correction status of the gap area and the non-gap area after the gap repair process. The average correction coefficient of the gap area refers to the average value of the attributes (brightness, color) of all pixels in the gap area of the LED screen. Assuming an LED screen with a gap, the gap area contains 10 pixels. The original correction coefficient of the LED screen is obtained by obtaining the original correction coefficient corresponding to each pixel in the gap area (denoted by C1, C2, C3...C10). Then the average correction coefficient of the gap area = (C1+C2+C3+...+C10) / 10. The calculation of the average correction coefficient of the non-gap area is similar and will not be repeated here.
[0053] The method provided by this invention, based on deep modeling of the physical parameters and correction coefficients of LED modules, designs a seam correction coefficient stripping algorithm. It only needs to read the screen's basic coefficients to achieve pixel-level seam correction coefficient removal, effectively improving seam correction accuracy. Furthermore, by eliminating hardware dependencies, it further reduces seam correction costs.
[0054] The present invention uses the following formula to calculate the removal repair coefficient:
[0055]
[0056] in, To remove the seam allowance; The coordinates of the gap are The original correction coefficients corresponding to the pixels; This represents the average value of the correction coefficients for the non-seamless area. This represents the average value of the correction coefficient for the gap area.
[0057] Specifically, for a pixel (x, y) at the seam, if the pixel has not been specially seamed, then (seamMean ≈ ScreenMean), the ratio is approximately 1; if the pixel has been significantly improved by seam repair (seamMean > ScreenMean), the ratio is less than 1. This application restores the pixel to its "unsealed" state by multiplying the excessively high original coefficient oriCoef(x, y) of the pixel at the seam by this factor less than 1.
[0058] The method provided in this application achieves precise stripping of the repair coefficient by statistically analyzing the average value of the correction coefficients in the gap area and the non-gap area, and uses these average values to calculate the removal repair coefficient, thereby improving the repair accuracy.
