Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

It is explicitly and implicitly understood by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0068] In order to better understand the image enhancement processing method for a spherical screen display provided in an embodiment of the present application, the image enhancement processing method for a spherical screen display in an existing solution is briefly introduced below. In the existing solution, when performing a spherical screen display, the image after fusion processing is usually displayed directly. Because the special curved surface structure of the spherical screen is not fully considered, the image is easily stretched, deformed and distorted when mapped to the spherical surface, and the clarity and proportion of each area of ​​the picture are unbalanced; there is a lack of targeted optimization for different viewing angles and viewing distances, and there will be blurring, color distortion, content occlusion, etc. when viewing at a specific viewing angle or distance; the reflection and scattering characteristics of light inside the spherical screen are not considered, resulting in uneven distribution of image contrast and brightness, which seriously affects the display accuracy and visual effects, and it is difficult to provide a high-quality, high-fidelity visual experience.

[0069] In order to solve the above-mentioned problems, an embodiment of the present application provides an image enhancement image processing method for a spherical screen display, which can fuse and three-dimensionally process the image to be displayed, and directly display the three-dimensional target display image, thereby improving the accuracy of the spherical screen image display and improving the display effect.

[0070] See also Figure 1 , Figure 1 The present invention provides a flowchart of an image enhancement method for a spherical screen display. Figure 1 As shown, the method includes:

[0071] 101. Obtain first attribute information of the target spherical screen.

[0072] The first attribute information may be used to indicate a collection of various characteristic parameters and related description information related to the target ball screen. The first attribute information may include, but is not limited to, the geometric shape characteristics of the ball screen, such as size (radius, diameter, etc.), curvature (the overall spherical curvature, the curvature change in different regions, etc.), the optical properties of the display material used (such as transmittance, reflectivity, etc.), and the specific properties of the light-emitting diode (LED) display module constituting the ball screen display, such as the distribution density of LED lamp beads, the luminous intensity of a single LED lamp bead, the arrangement of LED display modules in different regions, the size specifications of each module, etc.

[0073] By acquiring the first attribute information of the target spherical screen, the image can be processed specifically according to the characteristics of the spherical screen in subsequent steps, and how to adapt and adjust the image can be determined based on the first attribute information to achieve a better display effect.

[0074] 102. Perform three-dimensional processing on the image to be displayed according to the first attribute information to obtain a reference display image.

[0075] The camera can be used to capture multiple sets of static images of real scenes to obtain images to be displayed. Optionally, four cameras can be used to capture static images of the target scene, and the four cameras can respectively capture images of four different areas in the target scene to obtain four images to be displayed, which is not limited in this application.

[0076] The reference display image can be an intermediate product obtained after the image to be displayed is processed into three dimensions. The reference display image can be based on the first attribute information of the target dome (such as the geometric shape, curvature, distribution of LED display modules, etc. of the dome), converting the two-dimensional image to be displayed into an image form that adapts to the three-dimensional surface of the dome. The reference display image is the basis for subsequent enhancement processing and provides a preliminary reference data for adapting to the shape of the dome for further optimizing the display effect.

[0077] Based on the first attribute information of the target spherical screen obtained, corresponding deformation, mapping and other operations are performed, and a three-dimensional conversion operation can be performed on the image to be displayed, so that the original two-dimensional plane image can fit the three-dimensional curved surface structure of the spherical screen. For example, according to the curvature changes at different positions of the spherical screen, various parts of the image are stretched, twisted and adjusted, so that each element of the image can fit naturally and accurately on the surface of the spherical screen after processing, avoiding image deformation and distortion caused by shape mismatch when the plane image is directly projected onto the spherical screen, thereby generating a reference display image that can be displayed relatively reasonably on the spherical screen, which can lay the foundation for further optimization of the display effect in the future.

[0078] 103. Perform enhancement processing on the reference display image to obtain a target display image.

[0079] Among them, the target display image can be used to indicate the image generated after a series of operations such as three-dimensional processing and enhancement processing. The target display image fully considers the various characteristics of the target ball screen and the interference factors that may appear during the display process. Compared with the original image to be displayed, it has significantly improved in terms of fitting the ball screen shape and picture display quality. It is the final image version that can be used for display on the target ball screen and can bring high-quality visual experience to viewers.

[0080] After obtaining the reference display image, in order to overcome various factors that may affect the display effect in the ball screen display, optimization operations can be performed on the image, such as enhancement processing, to comprehensively consider multiple factors, such as the second attribute information of the LED display module, the direction of light beam divergence, and the resulting display interference information. Optionally, the reference display image can be split, the display conditions corresponding to each part can be analyzed, the pixel value, brightness, contrast and other attributes of each area of ​​the image can be adjusted in a targeted manner, and the image can be compensated and corrected to improve the overall display quality of the image, reduce problems such as uneven brightness and color deviation caused by overlapping light, and finally obtain an optimized target display image, so that it can present a clearer, more accurate, and better visual effect when displayed on the ball screen.

[0081] 104. Display the target display image through the target ball screen.

[0082] The target display image obtained through the above steps is presented using the target spherical screen as a specific display carrier. Optionally, the corresponding display control system can be used to accurately map the pixel information of the target display image to the corresponding positions on the spherical screen. With the help of the display function of the spherical screen, the image can be displayed with the expected high-quality effect, so that the viewer can see the optimized spherical screen image, completing the complete process from image preparation to final display.

[0083] In this example, by acquiring the first attribute information of the target spherical screen, the image to be displayed is three-dimensionally processed according to the first attribute information to obtain a reference display image, the reference display image is enhanced to obtain a target display image, and the target display image is displayed through the target spherical screen. Therefore, the image to be displayed can be three-dimensionally processed and then enhanced to obtain a target display image, and finally the target display image is displayed, thereby improving the accuracy of spherical screen image display.

[0084] In a possible implementation, this example uses four images to be displayed as an example for illustration. Specifically, a method for performing enhancement processing on the reference display image to obtain a target display image may include the following steps:

[0085] A1. extracting second attribute information of the LED display module of the target ball screen from the first attribute information;

[0086] A2. Split the reference display image according to the second attribute information of the LED display module to obtain k sub-reference display images;

[0087] A3, obtaining the light beam divergence direction information of the LED display module corresponding to k sub-reference display images, and obtaining k light beam divergence direction information;

[0088] A4, determining initial display interference information of the corresponding sub-reference display image when it is displayed according to the k light beam divergence direction information, and obtaining k initial display interference information;

[0089] A5. Determine display enhancement information of k sub-reference display images according to the k initial display interference information and the pixel values ​​of the k sub-reference display images to obtain k display enhancement information;

[0090] A6. Use k display enhancement information to enhance the corresponding sub-reference display images to obtain k sub-target display images;

[0091] A7. Combining the k sub-target display images to obtain the target display image.

[0092] Among them, the second attribute information of the LED display module of the target ball screen can be used to describe a set of parameters related to the characteristics of the LED display module in the target ball screen. The second attribute information of the LED display module can include but is not limited to the detailed characteristics of the LED display module in terms of physical structure, optical performance, etc., such as the arrangement and layout of LED lamp beads in the module (whether they are evenly distributed or arranged in a specific pattern), the density of the lamp beads (the number of lamp beads contained per unit area, which affects the fineness of the display and the uniformity of brightness), the luminous intensity of a single LED lamp bead (determines the brightness of its own light), the luminous angle range (reflects the angle of light divergence, affecting the coverage and interaction of light), and the splicing method between each LED display module (how to combine together to form a complete ball screen display surface, affecting the coherence of the image) and the size of the module itself (modules of different sizes have different effects on image segmentation and display effects), etc.

[0093] According to the extracted second attribute information of the LED display module, the three-dimensionally processed reference display image can be split to obtain k sub-reference display images. The k sub-reference display images can be understood as multiple local images. Since different LED display modules on the spherical screen have different performances and influences when displaying images, subdividing the overall reference display image according to the LED display modules can more accurately analyze the specific situation faced by the image corresponding to each local area in the subsequent display process, which is convenient for subsequent differentiated processing according to the characteristics of each module, so that each sub-reference display image can be better adapted to the corresponding LED display module.

[0094] For each LED display module corresponding to a sub-reference display image, its light beam divergence direction information is obtained, and k light beam divergence direction information can be obtained. The k light beam divergence direction information can be used to indicate the specific direction in which the light beam emitted by each LED display module spreads outward. Because when the LED lamp beads emit light, their light is not absolutely parallel, but has a certain divergence angle. Different LED display modules have different light beam divergence directions due to factors such as their internal lamp bead layout and the characteristics of the lamp beads themselves. Accurately grasping the light beam divergence direction information can more accurately judge the propagation and interaction of light in the spherical screen and the impact on image display, which is conducive to better analysis of display interference in the future.

[0095] Based on the beam divergence direction information of the LED display module corresponding to each sub-reference display image, the interference situation caused by the most initial and direct influence of light propagation during the image display process is analyzed, and k initial display interference information can be obtained. For example, when the light beams of different LED display modules overlap after divergence, the overlapping area may cause uneven brightness (may be too bright or too dark), mixed color deviation, etc., or some areas may appear darker due to insufficient light exposure. The above-mentioned information related to various phenomena caused by light propagation and interaction that are not conducive to normal and high-quality display of images is the initial display interference information. Through the initial display interference information, it is possible to clarify the key issues that need to be solved in the subsequent image enhancement processing.

[0096] The k display enhancement information can be understood as a set of related information used to optimize and enhance the sub-reference display image in a targeted manner after comprehensively considering the initial display interference information of the sub-reference display image and the pixel value characteristics of the sub-reference display image itself. The display enhancement information may include but is not limited to specific parameters or strategies for brightness adjustment, color correction, clarity optimization, and other aspects of the image.

[0097] The k optimized local images obtained after enhancing each sub-reference display image using the corresponding display enhancement information can be used as the above-mentioned k sub-target display images. It can be understood that compared with the original sub-reference display image, the sub-target display image overcomes the display interference problem analyzed previously, and its brightness is more uniform and reasonable, the color is more accurate and realistic, and the image is clearer and sharper. It can better adapt to the display requirements of the corresponding LED display module on the dome screen, and lay a good local foundation for the final integration to form a high-quality target display image.

[0098] The target display image is the complete image obtained by combining all enhanced sub-target display images according to their original corresponding position relationship and splicing order on the ball screen. The target display image can comprehensively consider the characteristics of different LED display modules on the ball screen and possible display interference. After layer-by-layer optimization, it can present better visual effects when displayed on the target ball screen, effectively improving the quality and accuracy of image display.

[0099] In a possible implementation, a method for determining the light beam divergence direction corresponding to each LED display module according to the second attribute information of the LED display module may include the following steps:

[0100] B1. Obtain the second attribute information of the LED display module to determine the light emitting direction information of the peripheral LED lamp beads of each LED display module, and obtain a first light emitting direction information set;

[0101] B2. Determine the edge light beam divergence information of each LED display module according to the first light emitting direction information set;

[0102] B3. Determine the central light beam direction information of each LED display module according to the second attribute information of the LED display module, and obtain a central light beam direction information set;

[0103] B4. Determine the beam divergence direction corresponding to each LED display module according to the central beam direction information and the corresponding edge beam divergence information in the central beam direction information set.

[0104] By analyzing the second attribute information of the LED display module, the light emission direction of the peripheral LED lamp beads of each LED display module is obtained, and the above-mentioned first light emission direction information set can be obtained. Among them, the first light emission direction information set can include the light emission direction vector of each peripheral LED lamp bead, and the direction vector can represent the light emission direction of the lamp bead in a coordinate system. For example, in a two-dimensional rectangular coordinate system, the two components of the vector can represent the angle relationship between the light emission direction and the coordinate axis, and this application does not limit this.

[0105] Based on the first light emitting direction information set, the outward diffusion of the light beam in the edge area of ​​the LED display module is further determined, and the edge light beam divergence information of each LED display module mentioned above can be obtained. The edge light beam divergence information may include information such as the direction trend and degree of divergence of the light beam in the edge area. Among them, the degree of divergence can be measured in many ways, such as the angle between the light emitting direction vectors of adjacent lamp beads, the change in the range covered by the light after a certain propagation distance, etc., and this application does not limit this.

[0106] By analyzing the distribution characteristics of LED lamp beads in the central area of ​​the LED display module, the light emission direction and other attribute information, and calculating (such as weighted average method), a set of light beam direction vectors representing the central area can be obtained. The light beam direction vector representing the central area can describe the main emission direction of the light in the central area of ​​each LED display module, and can reflect the main trend of light propagation in the central part of the module.

[0107] For each LED display module, a comprehensive analysis is performed in combination with its central beam direction information and edge beam divergence information. For example, taking the central beam direction as a reference and considering the influence of the edge beam divergence information on the overall beam divergence morphology, a beam divergence model can be constructed with the central beam direction as the axis of symmetry and the left and right sides gradually opening outward at a certain angle. Optionally, a mathematical function can be used to describe the above beam divergence direction, such as using a polar coordinate equation, with the center of the LED display module as the pole and the central beam direction as the polar axis direction, and determining the parameters in the function according to the edge beam divergence angle, thereby accurately representing the beam divergence direction corresponding to the LED display module.

[0108] The above-mentioned beam divergence direction can comprehensively describe the propagation trend of the light emitted by each LED display module in space, which is conducive to more accurately analyzing the interaction between the light beams of different modules and the impact on image display in the subsequent process, and helps to determine more accurate display interference information and perform more precise image enhancement processing.

[0109] In a possible implementation, a method for determining initial display interference information of a corresponding sub-reference display image when displaying the image according to k light beam divergence direction information to obtain k initial display interference information may include the following steps:

[0110] C1. Determine the beam overlap information between the corresponding LED display modules according to the k beam divergence direction information, and obtain a set of k beam overlap information;

[0111] C2. Determine initial display interference information when the corresponding reference display image is displayed according to the k light beam overlap information sets, and obtain k initial display interference information.

[0112] Based on the analysis of the k light beam divergence direction information, k light beam overlap information sets can be obtained to describe the intersection and overlap of light between the LED display modules corresponding to each sub-reference display image. Since the light beams emitted by each LED display module have their own specific divergence direction, in a spatial environment such as a dome screen, the light beams emitted by different modules may intersect together, and the k light beam overlap information sets can be used to specifically describe the intersection.

[0113] Further analysis based on the above-mentioned k sets of light beam overlap information can determine the relevant information used to describe the interference to the normal display of the image caused by the mutual overlap between light beams and other possible light propagation problems when the reference display image is displayed, that is, the above-mentioned k initial display interference information. The initial display interference information can cover multiple aspects of information, such as abnormal brightness caused by the superposition of light in the overlapping area (it may be too bright so that some details of the image are lost, or the light is unevenly mixed, causing local overbrightness or local overdarkness, etc.), color deviation (the overlapping and mixing of light beams of different colors changes the original color of the image, making the color inaccurate), and unclear image display and dark areas caused by the lack of light coverage or uneven coverage in certain areas.

[0114] For example, if the red and blue LED light beams in a certain overlapping area overlap more, the original image in this area should be displayed as green, but after mixing, it becomes cyan. This situation may be interference information regarding color deviation. If in an image area that should be displayed evenly and brightly, an obviously too bright light spot appears due to the overlapping of light beams, making it impossible to see the image details in this area, this situation may be interference information regarding brightness, and the present application does not impose any restrictions on this.

[0115] In this example, by determining k initial display interference information, various display problems caused by the divergence and overlap of light beams of each LED display module of the dome screen can be comprehensively and meticulously analyzed, so as to provide highly targeted data for subsequent image enhancement processing, so that during the correction process, targeted processing can be performed according to the specific interference conditions of each sub-reference display image, thereby effectively improving the brightness uniformity, color accuracy and detail clarity of the image when displayed on the dome screen, greatly enhancing the optimization accuracy of image display effects and visual experience, and allowing the dome screen display system to adapt to complex light propagation environments more intelligently and accurately, laying a solid foundation for presenting high-quality and high-fidelity images.

[0116] In a possible implementation, a method for determining display enhancement information of k sub-reference display images according to k initial display interference information and pixel values ​​of k sub-reference display images to obtain k display enhancement information may include the following steps:

[0117] D1. determining a display brightness value of a first sub-reference display image according to a pixel value of the first sub-reference display image, where the first sub-reference display image is any one of the k sub-reference display images;

[0118] D2. determining intermediate display interference information according to the display brightness value and the corresponding initial display interference information;

[0119] D3. determining the display enhancement information according to the intermediate display interference information;

[0120] D4. Repeat the above method of determining the display brightness value of the first sub-reference display image according to the pixel value of the first sub-reference display image, and determining the display enhancement information according to the intermediate display interference information, until the display enhancement information of k sub-reference display images is obtained, and k display enhancement information is obtained.

[0121] This embodiment takes the processing of the first sub-reference display image as an example for illustration, and does not constitute a limitation on the present application. A specific algorithm or calculation rule can be used to extract relevant data about brightness from these pixel values, and then determine the display brightness value of the first sub-reference display image. For example, the brightness components of each pixel in the image (in some color spaces such as the Red-Green-Blue (RGB) color space, the brightness can be calculated from the three components of red, green, and blue by a specific formula) can be weighted averaged and the brightness values ​​of all pixels can be merged to obtain a value that can represent the overall brightness of the first sub-reference display image, that is, the above-mentioned display brightness value.

[0122] After obtaining the display brightness value of the first sub-reference display image, the initial display interference information for the sub-reference display image obtained from the previous analysis (such as brightness anomalies and color deviations caused by light beam overlap) can be combined to further analyze and determine the intermediate display interference information, so as to comprehensively consider the original brightness state of the image and the interference caused by various light factors, so as to more accurately quantify the actual impact of these interferences on the image display.

[0123] Further, according to the intermediate display interference information obtained through analysis, corresponding strategies are formulated and specific adjustment parameters are determined, that is, the above-mentioned display enhancement information is determined. The display enhancement information can eliminate or reduce the adverse effects on the image display quality described by the intermediate display interference information through certain image processing means, such as adjusting brightness, color correction, image sharpening, etc., so that the first sub-reference display image can achieve better effects in subsequent display.

[0124] It is understandable that for each of the k sub-reference display images, the above series of operations from determining the display brightness value, to determining the intermediate display interference information in combination with the initial display interference information, and then to determining the display enhancement information can be performed. By processing each sub-reference display image in turn until the relevant calculation and analysis of all the sub-reference display images in the k sub-reference display images are completed, k display enhancement information corresponding to the k sub-reference display images can be obtained, so as to provide a comprehensive and accurate basis for the subsequent targeted enhancement processing of each sub-reference display image, which is conducive to improving the overall image display effect.

[0125] In this example, the display brightness value is determined by the pixel value, so that the original brightness state of the sub-reference display image can be quantified, providing basic data for subsequent processing; the intermediate display interference information is determined in combination with the initial display interference information, so that the actual degree of interference of the image can be accurately analyzed, so as to comprehensively consider the brightness of the image itself and the interference factors; the display enhancement information is determined according to the intermediate display interference information, so that an optimization strategy can be formulated for each sub-reference display image in a targeted manner to ensure that the display problem is effectively corrected; these steps are repeated for all sub-reference display images to obtain k display enhancement information, so as to achieve comprehensive and accurate enhancement of the entire image, thereby effectively improving the overall display quality of the image on the dome screen.
