[0032] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein.

[0034] Example 1

[0035] According to an embodiment of the present invention, an embodiment of a method for correcting a displayed image is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0036] Figure 1 is a flow chart of a method for correcting a displayed image according to an embodiment of the present invention. Figure 1 As shown, the method comprises the following steps:

[0037] Step S102, obtaining an image to be displayed, wherein the image to be displayed is an image to be displayed on a target display screen, and the target display screen includes a plurality of modules;

[0038] In step S102 provided in the present application, an image to be displayed is obtained.

[0039] The image to be displayed is involved, and the image to be displayed is an image for displaying on a target display screen, and may be a static picture or a dynamic video, and may be image data directly received from an image source.

[0040] Among them, a target display screen is involved, which is an LED display screen used to display the image to be displayed and has a certain splicing error, such as an LED display screen whose splicing accuracy index is lower than a predetermined threshold, a display screen that needs to be corrected for splicing errors, for example, an LED display screen with poor display effect due to splicing errors.

[0041] Among them, multiple modules are involved. The multiple modules are used to display a part of the image to be displayed and constitute the basic unit of the target display screen. The target display screen can be formed by splicing multiple modules. For example, by splicing LED modules, a larger LED display screen can be formed.

[0042] During the installation or on-site use of the display screen, there are deviations in the splicing positions between multiple modules, which leads to visual inconsistency problems on the display screen, affecting the viewing experience. However, considering the unavoidability of splicing errors, it is necessary to obtain the image to be displayed on the target display screen, so as to subsequently establish a display relationship between the target display screen and the image to be displayed on the target display screen, thereby compensating for the problem of poor display effect of the display screen caused by splicing errors based on this display relationship, and providing the necessary data basis.

[0043] It should be noted that there is no specific limitation on the method of obtaining the image to be displayed, and the method can be customized according to the actual application and scenario.

[0044] Step S104, determining the offsets corresponding to the multiple modules respectively;

[0045] In step S104 provided in the present application, the offsets corresponding to the plurality of modules are determined.

[0046] Among them, an offset is involved, which is the deviation between the current positions and the target positions corresponding to multiple modules during the splicing process, and can be a deviation in coordinate values ​​and a deviation in rotation angles.

[0047] Since the target display screen is composed of multiple modules and the stitching errors corresponding to each module are different, by determining the offsets corresponding to the multiple modules, subsequent error correction can be carried out in a targeted manner according to the specific errors of each module, thereby improving the accuracy of the image displayed on the display screen, ensuring the consistency of the display effect of the calibrated display screen, and improving the user's viewing experience.

[0048] It should be noted that there is no specific limitation on the method of determining the offsets corresponding to the multiple modules, and the settings can be customized according to the actual application and scenario.

[0049] Step S106, determining initial sub-images corresponding to the plurality of modules respectively according to the image to be displayed;

[0050] The initial sub-image is involved, and the initial sub-image is the initial sub-image that each module should display, determined before correction based on the size of the corresponding module and the image to be displayed.

[0051] Since the different stitching errors corresponding to each module will affect the display effects of the image displayed on the module, the initial sub-images corresponding to the multiple modules are determined according to the image to be displayed, and the relationship between the module and the corresponding sub-image is established, so that the correction of the image to be displayed in combination with the display device can be realized. In addition, the large image processing problem is decomposed into multiple small image processing problems. By determining the initial sub-images corresponding to the multiple modules, the display image on each module can be adjusted in a targeted manner, while reducing the computational complexity of the target display screen displaying the image to be displayed, which is helpful for subsequent error correction, thereby solving the problem of poor display effect of the LED display screen due to the influence of the stitching error.

[0052] It should be noted that the method for determining the initial sub-images corresponding to the multiple modules is not specifically limited here, and can be customized according to actual applications and scenarios.

[0053] Step S108, correcting the initial sub-images corresponding to the multiple modules respectively according to the offsets corresponding to the multiple modules respectively, to obtain target sub-images corresponding to the multiple modules respectively;

[0054] Among them, a target sub-image is involved, and the target sub-image is a sub-image obtained after correcting the corresponding initial sub-image according to the offsets corresponding to multiple modules respectively.

[0055] Since there are stitching errors between multiple modules in the target display screen, the corresponding parts of the images to be displayed on the multiple modules and the stitching parts between the modules may be misaligned, have gaps or overlaps. According to the offsets of the multiple modules previously determined, the initial sub-image of each module is corrected to generate a target sub-image. This correction process can make the target sub-images smoother and more coherent, ensuring that the entire display area presents a consistent and clear image, eliminating the influence of stitching errors on the image display of the display screen, thereby helping to subsequently improve the overall display quality and visual effects of the display screen.

[0056] It should be noted that the method for determining the target sub-images corresponding to the multiple modules is not specifically limited here and can be customized according to the actual application and scenario.

[0057] Step S110 , determining a target display image according to target sub-images corresponding to the plurality of modules, so that the target display screen performs display according to the target display image.

[0058] Among them, a target display image is involved, which is an image spliced ​​together from target sub-images corresponding to multiple modules and is used for actual display on a target display screen.

[0059] Since the target sub-images corresponding to the multiple modules are sub-images obtained by targeted correction based on the offset of the corresponding modules, an overall target display image for actual display on the target display screen is obtained based on the multiple target sub-images, thereby avoiding problems such as misalignment and faults of multiple module display images due to splicing errors, ensuring that the target display image actually displayed on the target display screen is a complete and coherent image, thereby improving the display effect of the target display screen and enhancing the user's comfortable viewing experience.

[0060] It should be noted that the method of determining the target display image based on the target sub-images corresponding to the multiple modules is not specifically limited here and can be customized according to actual applications and scenarios.

[0061] Through the above steps S102-S110, an image to be displayed is obtained, wherein the image to be displayed is an image to be displayed on a target display screen, and the target display screen includes multiple modules. The offsets corresponding to the multiple modules are determined. According to the image to be displayed, initial sub-images corresponding to the multiple modules are determined. According to the offsets corresponding to the multiple modules, the initial sub-images corresponding to the multiple modules are corrected respectively to obtain target sub-images corresponding to the multiple modules. According to the target sub-images corresponding to the multiple modules, a target display image is determined so that the target display screen displays according to the target display image. In this embodiment, based on the target display screen and multiple modules of the target display screen, the stitching error of the target display screen is analyzed to determine the offsets corresponding to the multiple modules, and the display relationship between the target display screen and the image to be displayed is determined by determining the initial sub-images corresponding to the multiple modules respectively, and the initial sub-images corresponding to the multiple modules are corrected in a targeted manner according to the offsets corresponding to the multiple modules to obtain corresponding target sub-images, so that the target sub-images are smoother and more coherent, and based on the corresponding target sub-images, the target display image for actual display on the target display screen is determined, ensuring that the entire display area presents a consistent and clear image, thereby solving the technical problem in the related art that the display screen has a poor display effect due to the influence of the stitching error.

[0062] As an optional embodiment, determining the offsets corresponding to multiple modules respectively includes: determining current position values ​​corresponding to the multiple modules respectively; determining target position values ​​corresponding to the multiple modules respectively, wherein the target position value is the position value corresponding to when the splicing accuracy index corresponding to the multiple modules respectively is greater than a predetermined threshold value; determining the offsets corresponding to the multiple modules respectively based on the current position value and the target position value.

[0063] In this embodiment, the steps of determining the offsets corresponding to the plurality of modules are described.

[0064] Among them, the current position value is involved, which is the position value corresponding to multiple modules after the target display screen is installed and initially positioned. Due to the corresponding splicing errors between multiple modules, there will be a deviation between the current position value and the ideal splicing position, so it is necessary to obtain the current position value and then perform correction.

[0065] Among them, a target position value is involved, which is the position value corresponding to multiple modules when the splicing is accurate, that is, when the expected splicing effect is achieved, and the splicing index of the corresponding module is greater than the predetermined threshold position value.

[0066] Among them, the splicing accuracy index is involved. The splicing accuracy index is a quantitative indicator used to represent the accuracy of the splicing corresponding to multiple modules. For example, if the splicing accuracy index between module A and module B is higher, it means that the accuracy of the splicing of module A and module B is higher, and the display effect after splicing is better.

[0067] Among them, a predetermined threshold is involved, which is pre-set and used to judge whether the splicing accuracy index of multiple modules, that is, the accuracy of splicing, has reached a predetermined accuracy threshold.

[0068] In the steps involved in this embodiment, the current position values ​​corresponding to the multiple modules are first determined, and the target position values ​​corresponding to the multiple modules are determined. Then, the offsets corresponding to the multiple modules can be determined based on the current position values ​​and the target position values. Since it is difficult to avoid splicing errors when multiple modules are spliced ​​together, resulting in deviations between the current position values ​​corresponding to the multiple modules and the target position values, by determining the current position values ​​corresponding to the multiple modules, an accurate data basis can be provided for the subsequent determination of the offsets corresponding to the multiple modules, thereby helping to improve the accuracy and efficiency of the entire correction process. By setting the splicing accuracy index and the predetermined threshold, a quantitative evaluation of the splicing effects corresponding to the multiple modules is achieved, so that the target positions corresponding to the multiple modules can be accurately determined, thereby helping to ensure that the multiple modules can achieve the expected splicing effects after correction. By determining the current position values ​​corresponding to the multiple modules and the target position values ​​corresponding to the multiple modules, the accurate calculation of the offsets corresponding to the multiple modules can be achieved, thereby providing reliable data support for the correction of the image to be displayed on the entire target display screen, thereby helping to compensate for the influence of the splicing error and ensuring the consistency of the display of the entire display screen.

[0069] As an optional embodiment, initial sub-images corresponding to multiple modules are determined based on the image to be displayed, including: determining a predetermined viewing point and an initial virtual camera center point corresponding to the image to be displayed, wherein the predetermined viewing point is a position point predetermined in the real space for viewing a target display screen, and the initial virtual camera center point is a position point for shooting the image to be displayed; determining a positional relationship between the predetermined viewing point and the initial virtual camera center point; and determining initial sub-images corresponding to multiple modules based on the positional relationship.

[0070] In this embodiment, the step of determining initial sub-images corresponding to a plurality of modules is described.

[0071] Among them, it involves a predetermined viewing point, which is a predetermined viewing point in real space for viewing the target display screen. At this predetermined viewing point, the viewer can clearly see the content of the entire display screen with the best visual effect. For example, in front of a large LED display screen, the predetermined viewing point can be the center of the auditorium.

[0072] Among them, an initial virtual camera center point is involved, which is the point in the virtual space corresponding to the image to be displayed where the virtual camera renders the scene in the virtual space, thereby affecting the perspective effect and viewing angle of the image.

[0073] Among them, the positional relationship is involved, which is the relative spatial relationship between the predetermined viewing point and the initial virtual camera center point. This relationship reflects how the image to be displayed is mapped from the corresponding virtual space to the target display screen in the real space, and the visual effect of the image seen by the viewer at the predetermined viewing point. For example, if the predetermined viewing point and the initial virtual camera center point are on the same horizontal line and the distance is moderate, then the image seen by the viewer at the predetermined viewing point should be clear and undistorted. If there is a large height difference or horizontal distance between the two, then the viewing angle or zoom ratio of the image may need to be adjusted to ensure that the viewer can see the best display effect.

[0074] In the steps involved in this embodiment, first determine the position point of the predetermined viewing target display screen in the real space, that is, the predetermined viewing point, and the initial virtual camera center point corresponding to the image to be displayed. Then, the positional relationship between the predetermined viewing point and the initial virtual camera center point can be determined. Thus, based on the positional relationship, the initial sub-images corresponding to the multiple modules are determined. By determining the predetermined viewing point, the initial virtual camera center point corresponding to the image to be displayed, and the positional relationship between the predetermined viewing point and the initial virtual camera center point, it can be ensured that the image to be displayed mapped from the virtual space to the real space can maintain the correct perspective effect and viewing angle, and then it can be determined how to accurately divide the image to be displayed into the corresponding multiple modules, which is helpful for subsequent correction of the stitching errors corresponding to the multiple modules, so that the multiple modules jointly present a complete, high-quality image, ensuring the consistency of the display of the entire display screen.

[0075] As an optional embodiment, initial sub-images corresponding to multiple modules are determined based on positional relationships, including: when a predetermined viewing point does not coincide with an initial virtual camera center point, adjusting the initial virtual camera center point based on the predetermined viewing point to obtain a target virtual camera center point, wherein the target virtual camera center point coincides with the predetermined viewing point; adjusting an image to be displayed based on the target virtual camera center point to obtain a viewpoint-adjusted image; and determining initial sub-images corresponding to multiple modules based on the viewpoint-adjusted image.

[0076] In this embodiment, the step of determining initial sub-images corresponding to a plurality of modules is described.

[0077] Among them, the target virtual camera center point is involved. The target virtual camera center point is adjusted according to the predetermined viewing point when the predetermined viewing point does not coincide with the initial virtual camera center point, so that the initial virtual camera center point and the predetermined viewing point are aligned, that is, the point where the perspective of the virtual camera matches the perspective of the viewer in the real space. Through the target virtual camera center point, the image to be displayed seen by the viewer at the predetermined viewing point can be undistorted.

[0078] Among them, a viewpoint adjustment image is involved, which is an image re-rendered at the target virtual camera center point after adjusting the virtual camera rendering viewing angle according to a predetermined viewing point, that is, the initial virtual camera center point.

[0079] In the steps involved in this embodiment, when the predetermined viewing point does not coincide with the initial virtual camera center point, it indicates that the image to be displayed needs to be adjusted. Therefore, the initial virtual camera center point can be adjusted according to the predetermined viewing point to obtain the target virtual camera center point so that the target virtual camera center point coincides with the predetermined viewing point. Then, according to the target virtual camera center point, the image to be displayed is adjusted to obtain a viewpoint adjustment image. Finally, according to the viewpoint adjustment image, the initial sub-images corresponding to the multiple modules are determined. Because in the process of stitching error correction of the target display screen, if the initial virtual camera center point does not coincide with the predetermined viewing point, the displayed image may cause perspective distortion or inconsistent viewing angles. By adjusting the position of the virtual camera to obtain the target virtual camera center point and re-rendering the viewpoint adjustment image, the image can be accurately segmented and allocated to the corresponding module according to the viewpoint adjustment image, which is helpful for the subsequent stitching error correction.

[0080] As an optional embodiment, according to the offsets corresponding to the multiple modules, the initial sub-images corresponding to the multiple modules are corrected respectively to obtain target sub-images corresponding to the multiple modules, including: when the corresponding offsets include corresponding coordinate offsets and corresponding rotation angle offsets, according to the coordinate offsets corresponding to the multiple modules, the initial sub-images corresponding to the multiple modules are coordinate-shifted to obtain corrected sub-images corresponding to the multiple modules; according to the rotation angle offsets corresponding to the multiple modules, the corrected sub-images corresponding to the multiple modules are coordinate-shifted to obtain target sub-images corresponding to the multiple modules.

[0081] In this embodiment, the step of determining target sub-images corresponding to a plurality of modules is described.

[0082] Among them, the coordinate offset is involved. The coordinate offset is the coordinate value deviation of the current position value relative to the target position value corresponding to multiple modules. The coordinate value represents the values ​​of multiple modules in the horizontal, vertical and depth directions, which can be expressed by the displacement values ​​of the three axes of x, y and z. For example, in the splicing process of the LED display screen, if the position of a certain LED module is slightly to the left or upward, then its coordinate offset will be a negative or positive x-axis or y-axis offset value. By adjusting the coordinate offset of this module, it can be moved to the correct position.

[0083] Among them, the rotation angle offset is involved, which is the rotation angle deviation of the current position direction of multiple modules relative to the target position direction during the splicing process. It can be represented by three rotation angles α, β, and γ, where α represents rotation around the x-axis, β represents rotation around the y-axis, and γ represents rotation around the z-axis.

[0084] Among them, a correction sub-image is involved, which is the corresponding sub-image obtained after the initial sub-image is corrected by the coordinate offset. The correction sub-image has been moved according to the coordinate offset of the corresponding module to ensure that the image parts corresponding to multiple modules are in the correct position, which is the basis for the subsequent rotation angle offset correction.

[0085] In the steps involved in this embodiment, according to the coordinate offsets corresponding to the multiple modules, the initial sub-images corresponding to the multiple modules are coordinate-shifted to obtain the correction sub-images corresponding to the multiple modules. According to the rotation angle offsets corresponding to the multiple modules, the correction sub-images corresponding to the multiple modules are coordinate-shifted to obtain the target sub-images corresponding to the multiple modules. By coordinate-shifting the initial sub-image according to the coordinate offset of each module, it is possible to ensure that the image portion corresponding to each module is located in the correct position, which solves the problem that the initial sub-image corresponding to each module is inaccurately positioned on the display screen due to the deviation of the splicing positions of multiple modules during the target display screen splicing process, thereby causing the image displayed on the target display screen to be misplaced, broken or overlapped, and also provides a basis for the subsequent rotation angle offset correction. By rotating the correction sub-image according to the rotation angle offset of each module, it is possible to ensure that the image portion corresponding to each module presents the correct direction, which solves the problem that the image portion corresponding to each module is tilted, distorted or deformed on the display screen due to the rotation angle deviation corresponding to the multiple modules during the target display screen splicing process. By correcting according to the coordinate offset and the rotation angle offset, target sub-images corresponding to multiple modules are obtained, which ensures the accuracy and reliability of the entire correction process and helps to achieve a consistent, flat and aligned display effect for the overall target display screen.

[0086] As an optional embodiment, according to the offsets corresponding to the multiple modules, the initial sub-images corresponding to the multiple modules are corrected respectively to obtain target sub-images corresponding to the multiple modules, including: determining extended images corresponding to the multiple initial sub-images, wherein the extended image is an image obtained by extending the edge of the corresponding initial sub-image; according to the offsets corresponding to the multiple modules, the extended images corresponding to the multiple modules are corrected respectively to obtain target sub-images corresponding to the multiple modules.

[0087] In this embodiment, the step of determining target sub-images corresponding to a plurality of modules is described.

[0088] Among them, an extended image is involved, which is the corresponding image obtained by extending the edge of the initial sub-image. For example, when correcting the initial sub-image corresponding to each module, if these initial sub-images are directly corrected, some problems will appear in the edge part. Therefore, an extended image is first generated for each initial sub-image. This extended image adds extra pixels outside the edge of the original image, and then these initial sub-images are corrected. Since the extended image adds extra pixels, the edge part problem can be better handled during the correction process, thereby obtaining a higher quality corrected image.

[0089] In the steps involved in this embodiment, the extended images corresponding to the multiple initial sub-images are determined, wherein the extended images are images obtained by extending the edges of the corresponding initial sub-images. According to the offsets corresponding to the multiple modules and the extended images corresponding to the multiple modules, the target sub-images corresponding to the multiple modules are obtained. By determining the extended images, the edge problems that may occur during the correction of the multiple initial sub-images are solved, that is, when the initial sub-images corresponding to the multiple modules are corrected according to the offsets corresponding to the multiple modules, if the original image is directly transformed, it may cause blank, blurry or distorted edges. By determining the extended images corresponding to the initial sub-images, it can be ensured that there is enough pixel information to fill these edge areas during the correction process, thereby improving the quality of the corrected image.

[0090] As an optional embodiment, after determining the target display image according to the target sub-images corresponding to the multiple modules respectively, so that the target display screen displays according to the target display image, it also includes: determining the update offsets corresponding to the multiple modules respectively. According to the update offsets corresponding to the multiple modules respectively, the target sub-images displayed by the multiple modules are corrected respectively to obtain the update sub-images corresponding to the multiple modules respectively. According to the update sub-images corresponding to the multiple modules respectively, an update display image is determined so that the target display screen displays according to the update display image.

[0091] In this embodiment, the step of determining to update the display image is described.

[0092] Among them, the update offset is involved. The update offset is the offset confirmed in real time when multiple modules are calibrated in real time to optimize the display effect in real time after calibration (i.e. after the target sub-image is obtained). The offset comes from various factors, such as deformation caused by thermal effects during the display process, or mechanical wear after long-term use.

[0093] Among them, an updated sub-image is involved, and the updated sub-image is a corresponding sub-image obtained after correction based on the target sub-image and the updated offset. For example, after obtaining the updated offset, the target sub-image corresponding to each LED module can be fine-tuned based on the updated offset.

[0094] Among them, it involves an updated display image, which is an image formed by splicing updated sub-images corresponding to multiple modules and is used for actually displaying on a target display screen.

[0095] In the steps involved in this embodiment, the update offsets corresponding to the multiple modules are first determined. According to the update offsets corresponding to the multiple modules, the target sub-images displayed by the multiple modules are corrected to obtain the update sub-images corresponding to the multiple modules. According to the update sub-images corresponding to the multiple modules, the update display image is determined so that the target display screen is displayed according to the update display image. By determining and applying the update offset in real time, the display position of each module can be dynamically adjusted to adapt to the changes in the display process, and the display position offset of the module caused by various factors (such as deformation caused by thermal effects, mechanical wear after long-term use, etc.) during the display process of the target display screen is effectively solved, which causes the display image to be distorted or misaligned, and ensures that each module can accurately display the image part that it should display, thereby maintaining the accuracy and consistency of the overall display, and achieving the improvement of the display effect of the target display screen and the optimization of the user experience.

[0096] Based on the above embodiments and optional embodiments, an optional implementation is provided, which is described in detail below.

[0097] In the related art, in the LED display manufacturing industry, the conventional color correction method is mainly carried out at the factory, usually by performing pixel-by-pixel color correction on each module installed in the standard unit to perform color correction on the LED display to ensure the color consistency of each module. However, when assembling LED modules on the factory production line and installing LED displays on site, there is a problem of poor display effects of LED displays due to the influence of installation errors.

[0098] In view of this, an optional embodiment of the present invention provides a method for correcting a displayed image, which can also be called a real-time display screen calibration method, which can effectively solve the technical problem in the related art that the display screen has poor display effect due to the influence of splicing errors.

On the basis of this conventional product factory correction, a new pre-stage correction is added, that is, a visual deviation extraction and algorithm compensation is formed between the display image source and the customer's use site where the final LED product is assembled, and the image source is adjusted in real time to achieve a perfect visual effect. It can be understood that conventional correction is the correction of LED display devices, and the optional implementation method of the present invention is how to combine the display content with the correction of the display device.

[0101] By combining the actual installation conditions and visual deviations of the display device, the image source is adjusted in real time to compensate for visual inconsistencies caused by installation errors or other factors. This ensures that the display screen can present a perfect visual effect in the actual use environment. The focus of the optional implementation of the present invention is how to establish a closer connection between the display content and the display device to achieve higher display accuracy and consistency.
