Abstract

[0034] In response to the problem of low accuracy of scene maps generated by traditional technical solutions, the present application provides a scene map generation system, which uses a design element extraction module to extract the hue, color temperature and visual focus of the scene design drawing, uses a design element storage module to construct a color configuration file based on the hue, color temperature and visual focus, and then uses an image decoding module to generate a scene map corresponding to the scene design drawing based on the color configuration file. In the process of generating the scene map, the design information is fully integrated, which is conducive to improving the accuracy of the scene map. At the same time, by introducing global information, the restoration degree of the scene map to the scene design drawing is effectively guaranteed.
[0035] The scene map generation system provided by this application is described in detail below.
[0036] like Figure 1 As shown, the scene map generation system includes a design element extraction module 101, a design element storage module 102 and an image decoding module 103, and each module is connected in sequence.
[0037] The design element extraction module 101 is used to extract the hue, color temperature and visual focus of the scene design drawing respectively, and send the hue, color temperature and visual focus to the design element storage module 102.
[0038] In an embodiment of the present application, the scene design drawing may be a game screen design drawing or an architectural design drawing, etc. It is an important tool for designers to express design plans, communicate ideas, and demonstrate effects, and presents design concepts and implementation plans in the form of drawings or images.
[0039] The following describes the process of extracting the color tone of the scene design drawing by the design element extraction module 101, which specifically includes steps a to c:
[0040] Step a: convert the scene design drawing from the RGB space to the HSV color space, obtain the HSV image corresponding to the scene design drawing, and extract the hue of the HSV image.
[0041] Specifically, first, the color value of each pixel in the RGB image is converted to the corresponding HSV color value.
[0042] It should be noted that the above conversion can be achieved through mathematical formulas or common color space conversion functions provided in image processing libraries.
[0043] Then, extract the hue channel from the converted HSV image.
[0044] It should be noted that the hue channel represents the color type or category of each pixel in the image. Usually, the hue value range is 0 to 360 degrees.
[0045] Step b: segment the hue according to the number of pixels corresponding to the scene design diagram to obtain multiple pixel blocks, and use the color average of each pixel block as the sub-tone corresponding to the pixel block.
[0046] The plurality of pixel blocks correspond to a plurality of theme colors of the scene design drawing, each theme color corresponds to at least one pixel block, and each pixel block includes at least one pixel of the scene design drawing.
[0047] The above-mentioned process of segmenting the hue is as follows: converting RGB into the color value of the HSV space, sorting and segmenting the hue, and extracting the sub-hue.
[0048] The calculation process of the above color average value is shown in steps I to III:
[0049] Step I: sort the pixels in each pixel block according to the hue value (H).
[0050] Step II: If the number n of pixels in the pixel block is an odd number, the color average is the color value of the (n+1) / 2th pixel after sorting, otherwise execute step III.
[0051] Step III: If the number n of pixels in the pixel block is an even number, the color average is the average of the color values of the sorted n / 2th pixel and the (n / 2)+1th pixel.
[0052] Step c: using the sub-tones corresponding to the plurality of pixel blocks as the tones of the scene design drawing.
[0053] It should be noted that in the embodiments of this application, the color temperature is obtained from the pre-configured information of the scene design. For example, the color temperature is pre-specified by the designer and the data format is a string consisting of a four-digit value such as "6500K" or "3000K" followed by the letter "K". For example, when the color temperature is "6500K", it indicates that the color tone of the scene design is biased towards blue.
[0054] Compared with RGB images, HSV images themselves are composed of three components: hue, saturation, and value, which are more suitable for hue extraction. Therefore, this application converts the scene design diagram from RGB space to HSV color space.
[0055] The following is an exemplary description of the process of extracting the visual focus of the scene design drawing by the design element extraction module 101 in the embodiment of the present application.
[0056] Specifically, a Fourier transform is performed on the scene design drawing to obtain the visual focus. The visual focus represents the low-frequency information corresponding to the scene design drawing. During the decompression and restoration process of the scene design drawing, the visual focus can ensure that the scene map can be accurately restored to the design effect corresponding to the scene design drawing.
[0057] The design element storage module 102 is used to construct a color profile according to hue, color temperature, and visual focus.
[0058] In the embodiments of this application, the color configuration file is independent of the scene design. Its format can be set to JSON and contains the image path (pointing to the original material image to be used for texture generation), image description (providing a detailed description or guidance of the texture content), hue, color temperature, and visual focus information. This file can exist independently of the image and can be loaded from the network or locally based on the association relationship when used.
[0059] The image decoding module 103 is used to generate a scene map corresponding to the scene design drawing according to the color configuration file.
[0060] The following describes the workflow of the image decoding module 103 in detail, as shown in steps A to C:
[0061] In step A, a decoder is used to decode the scene design diagram into original RGB color data, and a visual focus in a color configuration file is written into the original RGB color data to obtain first RGB color data.
[0062] The above-mentioned original RGB color data includes the RGB value corresponding to each pixel in the scene design image.
[0063] Step B: writing the color tone in the color profile into the first RGB color data to obtain second RGB color data.
[0064] Step C: Using the color temperature in the color configuration file as the color temperature of the second RGB color data, obtaining a scene design drawing according to the image path and image description in the color configuration file, and obtaining a scene map according to the scene design drawing and the second RGB color data.
[0065] From the above content, it can be seen that the scene map generation system provided by this application uses a design element extraction module to extract the hue, color temperature and visual focus of the scene design drawing, uses a design element storage module to construct a color configuration file based on the hue, color temperature and visual focus, and then uses an image decoding module to generate a scene map corresponding to the scene design drawing based on the color configuration file. In the process of generating the scene map, the design information such as the hue, color temperature and visual focus of the scene design drawing is fully combined, which is conducive to improving the accuracy of the scene map. At the same time, by constructing a color configuration file as global information, the restoration degree of the scene map to the scene design drawing is effectively guaranteed.
[0066] The following is an exemplary description of the execution process of the scene map generation system in another embodiment of the present application. Figure 2 As shown:
[0067] First, the designer designs the scene and forms a scene design drawing.
[0068] This step corresponds to Figure 2 Design the scene and form the scene design drawing.
[0069] Then, the design drawing information is extracted (the hue, color temperature and visual focus of the scene design drawing are extracted respectively).
[0070] This step corresponds to Figure 2 Extracting design drawing information.
[0071] Then, the design drawing information is written into the color profile (a color profile is constructed based on hue, color temperature and visual focus, and the color profile includes image path, image description, hue, color temperature and visual focus).
[0072] This step corresponds to Figure 2 Write color profiles and file storage in .
[0073] Then, the color profile is stored in Json format.
[0074] This step corresponds to Figure 2 File management in .
[0075] Finally, when the map is generated, the color configuration file is downloaded, and according to the picture path and picture description in the color configuration file, the original scene design picture is downloaded, and finally the scene design picture corresponding to the scene map is generated based on the original scene design picture and the color tone, color temperature and visual focus in the color configuration (picture decoding restoration).
[0076] This step corresponds to color configuration file download, picture download and picture decoding restoration in Figure 2
[0077] The application has the advantages that: the design information is innovatively introduced, the scene global color tone information, color temperature information and local picture own detail information are extracted and stored into the color configuration file, the problem of repeated storage of the local picture color tone information of the consistent or close color tone in the scene is reduced, the color temperature is introduced to increase the consistency of the scene rendering effect and the design effect, the visual focus information of the local picture is introduced, in the case of missing original picture, the picture close to the original picture effect can be generated through the visual focus information, scene color tone information and color temperature information, so that the rendering process can be normally carried out, the rendering effect is close to the design effect, and the client service accessibility and user experience are greatly improved.
[0078] The above is the preferred embodiment of the application, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles described in the application, and these improvements and refinements should also be regarded as the protection scope of the application.
