Technical Field

[0001] This application relates to the technical field of 3D modeling and printing, and particularly to a method, system, device, and medium for 3D conversion of 2D vector files of advertising characters. Background Art

[0002] Currently, with the continuous improvement of the requirements for visual effects in the advertising design industry, the traditional 2D advertising character design method has gradually been unable to meet the needs. Although 2D design is simple and easy to process, in practical applications, especially in scenarios such as billboards and display models, the three-dimensional effect is particularly important. Therefore, the production of 3D advertising character models has become an important development direction in the advertising industry.

[0003] Existing 3D advertising character generation methods usually rely on manual modeling or converting 2D graphics into 3D models through complex 3D modeling software (such as 3DMax, AutoCAD, etc.). These software require users to have strong 3D modeling skills, and the operations are complex with a long learning curve. At the same time, traditional 3D modeling methods are often time-consuming and costly, especially in the design of large-scale customized advertising characters, where the efficiency problem is more prominent. In addition, existing 3D design solutions rarely match the actual needs of users and cannot achieve fast and efficient feedback and adjustment.

[0004] The above-mentioned existing technical solutions have the following defects: Traditional 3D modeling software requires users to have certain modeling skills, which have a high learning threshold and complex operations for non-professionals, so there is room for improvement.

[0016] In one example, the present application can be further configured as follows: The three-dimensional model after preliminary adjustment is simulated by using the augmented reality technology. During the simulation of the three-dimensional model after preliminary adjustment, feedback information is obtained, and based on the feedback information, the three-dimensional model after preliminary adjustment is secondarily adjusted to generate a perfected three-dimensional model, including: Render the three-dimensional model after preliminary adjustment into the required scenario set by the user by using the augmented reality technology; Analyze the feedback information to generate adjustment parameters for the three-dimensional model after preliminary adjustment, and secondarily adjust the three-dimensional model after preliminary adjustment according to the adjustment parameters.

Detailed implementation manners

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] In one embodiment, as Figure 1 shown, the present application discloses a method for three-dimensional conversion of two-dimensional vector files of advertising characters, which specifically includes the following steps: S10: Obtain the imported two-dimensional vector file, parse the two-dimensional vector file, extract the graphic feature information of the two-dimensional vector file, and generate graphic elements of the two-dimensional vector file.

[0028] Specifically, first, obtain the imported two-dimensional vector file. The imported two-dimensional vector file can be in common formats, such as SVG or DXF formats, and the file contains geometric data such as points, lines, and curves. By parsing these files, extract the path data in the files. The path data includes, but is not limited to, straight line segments, arc segments, closed regions, etc. By reading the coordinate points and control points in the path data, analyze the shape and boundary information of each graphic. The generation of graphic elements will be converted into geometric elements according to these path information to form a preliminary two-dimensional graphic description, such as a point set, a line segment set, a closed region, etc., further providing data support for three-dimensional modeling. For example, for a curved path, by parsing its control points, generate a series of continuous line segments or curve segments to form linear or curved graphic elements.

[0029] S20: Obtain the graphic design requirements, and generate a corresponding initial three-dimensional model based on the graphic design requirements and the graphic elements.

[0030] Specifically, when obtaining graphic design requirements, the user may provide specific three-dimensional design requirements, such as dimensions, proportions, thickness, depth, etc. These design requirements can be input through the user interface and passed to the model generation algorithm. Based on these design requirements and the geometric features of the graphic elements, the process of generating the initial three-dimensional model includes extending the two-dimensional graphic elements into the three-dimensional space through three-dimensional modeling algorithms. For example, for a simple rectangular path, the design requirements input by the user may require it to be extruded into a rectangular cube with a certain thickness, while for a circular path, the design requirement may be to rotate it into a cylinder. According to these requirements, three-dimensional modeling algorithms such as extrusion, stretching, and rotation are used to transform the two-dimensional graphic elements into a preliminary three-dimensional model.

[0031] S30: Obtain the user's editing information, and adjust the initial three-dimensional model according to the editing information to generate a preliminarily adjusted three-dimensional model.

[0032] Specifically, the user inputs editing information through the graphic interface, including but not limited to dimensions, shapes, rotation angles, translation distances, materials, etc. These information can be interactively operated through input boxes, sliders, rotation handles, etc. According to these editing information, geometric transformations are performed on the initial three-dimensional model. For example, the user can adjust the dimensions of a certain graphic element through the interface. The system scales the dimensions of the graphic through a mathematical formula according to the user's input, changing the volume or proportion of the three-dimensional model; if the user adjusts the position of the model, the system moves the graphic element from the original position to the new position through a translation transformation formula; for rotation, the system rotates the model around a certain axis through a rotation matrix according to the rotation angle set by the user. At this time, the generated is a preliminarily adjusted three-dimensional model, which already takes into account the user's editing requirements and reflects the effect after real-time adjustment.

[0033] S40: Use augmented reality technology to simulate the preliminarily adjusted three-dimensional model. During the simulation of the preliminarily adjusted three-dimensional model, obtain feedback information, and perform secondary adjustment on the preliminarily adjusted three-dimensional model according to the feedback information to generate a perfected three-dimensional model.

[0034] Specifically, the enhanced reality technology is used to render the preliminarily adjusted 3D model into the required scenario set by the user. The 3D model can be projected into the actual environment, allowing the user to view the matching situation between the model and the surrounding environment through a smart device. For example, the user may want to see the effect of an advertising word model in a store window. Through the enhanced reality technology, the model is projected into the simulated scenario and adjusted according to the actual requirements in the scenario, such as the relative positions with walls and other advertising items. After the user observes, feedback is provided through input methods such as touch screens or voices. The feedback information may include whether the size of the model is appropriate, whether the position of the model is proper, and whether the visual effect meets the requirements, etc. The system makes secondary adjustments by adjusting parameters to optimize the effect of the 3D model until the user is satisfied, and a perfected 3D model is generated.

[0035] S50: According to the preset format algorithm, the perfected 3D model is output in the file format corresponding to the device.

[0036] Specifically, first, the system identifies the file format requirements according to the device type and performs format conversion on the 3D model according to these requirements. During the format conversion process, the system reorganizes the 3D data of the model according to the specifications of the target format. For example, if the STL format is output, the system will convert the 3D model into a file composed of triangular meshes and perform necessary optimizations, such as reducing the number of faces to adapt to the accuracy requirements of the printer, or simplifying complex geometric data to reduce the file size. Finally, the system will output a 3D file format suitable for printing or display according to the requirements of the target device, ensuring that the file can be correctly displayed or printed on the target device.

[0037] By adopting the above technical solutions, by importing and parsing two-dimensional vector files, automatically extracting the graphic feature information in the files, and converting it into basic graphic elements that can be used for 3D modeling, the complexity of manual modeling is simplified, the efficiency of graphic data processing is improved, and the accurate conversion of graphics and the smoothness of subsequent operations are ensured; by combining the design requirements provided by the user and the extracted graphic elements, an initial 3D model that meets the requirements is automatically generated, ensuring that the design of the 3D model meets the actual usage requirements and improving the automation generation efficiency of the model, reducing manual intervention and design errors; by obtaining the editing information input by the user, dynamically adjusting the initial 3D model, and generating a preliminary adjusted model that meets the user's requirements, the flexibility of personalized customization is enhanced, enabling the user to participate in and modify the model in real time during the design process, further improving the design accuracy and satisfaction; by using augmented reality technology to embed the preliminarily adjusted 3D model into the actual scene, the user can intuitively view the matching degree between the model and the actual environment and provide real-time feedback based on this. According to this feedback information, the system can perform secondary adjustment to optimize the details and performance of the model to ensure its coordination with the environment and the matching degree of the design requirements; by applying the preset format algorithm, the system automatically converts the improved 3D model into the file format supported by the target device, ensuring that the output file can be seamlessly compatible with the target device, simplifying the steps of file conversion, reducing format compatibility issues, and improving the efficiency and accuracy of device adaptation.

[0038] In one embodiment, as Figure 2 shown, in step S10, that is, obtaining the imported two-dimensional vector file, parsing the two-dimensional vector file, extracting the graphic feature information of the two-dimensional vector file, and generating the graphic elements of the two-dimensional vector file, specifically including: S11: Identify and parse the path data in the two-dimensional vector file, where the path data includes straight lines, curves, arcs, closed regions, and boundary information.

[0039] Specifically, by parsing the path data in the two-dimensional vector file, various path elements in the file will be scanned first. These paths include straight line segments, curves, arcs, and closed regions. During the parsing process, for straight line segments, by extracting the starting and ending coordinates on the path, its linear characteristics are determined; for curve and arc paths, by calculating the control points in the path, a mathematical representation form of the curve is generated, such as a Bezier curve or a spline curve; for closed regions, it is necessary to identify whether the path forms a closed loop, usually by judging whether the starting and ending coordinates are the same to determine its closedness. After each path type is parsed, it will be converted into a standard geometric data format to ensure that each path element can be correctly identified and used in subsequent processing.

[0040] S12: Extract and classify the path data, generate a graphic structure according to the geometric attributes of the path data, and convert the graphic structure into graphic elements.

[0041] Specifically, after extracting the path data, classify the paths according to the geometric attributes of each path, such as linearity, curvature, and closedness. Straight line segments will be marked as linear elements, curved and arc-shaped paths will be classified as curved elements, and closed paths will be regarded as surface area elements. Each type of path will be converted into a different graphic structure according to its attributes. These graphic structures can be simple sets of line segments, complex curve descriptions, or even polygon regions. For each graphic element, the system will perform optimization processing through mathematical formulas or algorithms according to its type and structure, such as Bezier curve fitting, least squares method, etc., to generate standard graphic elements suitable for 3D modeling. For example, for a closed rectangular path, after parsing, it will be converted into a graphic structure containing four straight line segments, providing operable geometric data for subsequent 3D modeling.

[0042] S13: If the path data contains multiple graphics, based on the graphic segmentation algorithm, separate and optimize the contours and connection methods of each graphic in the path data.

[0043] Specifically, when the path data contains multiple graphics, use the graphic segmentation algorithm to separate these graphic elements from the overall path to ensure that the contour of each graphic can be processed independently. For example, when processing a path containing multiple intersecting or overlapping graphics, first identify the boundaries of each graphic through geometric analysis, use the algorithm to segment these graphics into independent units, and perform optimization processing to ensure that the contour of each graphic is clear and the connection method is reasonable. During the optimization process, by analyzing the boundary points and curve segments of each graphic element, apply algorithms such as convex hull algorithm, discretization segmentation method, or curve smoothing technology to remove redundant points or curves, avoid overlapping and redundant geometric elements, so as to ensure that the contour of each graphic meets the actual requirements and can be used for subsequent modeling and rendering operations. This optimization step can help improve the quality of subsequent 3D modeling and reduce potential geometric errors or invalid calculations.

[0044] In one embodiment, as Figure 3 shown, in step S20, that is, obtaining the graphic design requirements, based on the graphic design requirements and graphic elements, generate the corresponding initial 3D model, specifically including: S21: Deeply analyze the geometric features of each graphic element in the graphic elements, and calculate the 3D space coordinates and shapes corresponding to each graphic element in the graphic elements.

[0045] Specifically, first, according to the types of graphic elements, such as straight lines, curves, arcs, closed regions, etc., analyze the spatial relationships of each graphic element through geometric derivation or mathematical modeling methods. For straight line segments, using the known starting and ending point coordinates, calculate their representations in three-dimensional space by means of simple linear equations to obtain the spatial coordinates and lengths of the straight lines; for curve elements, such as Bezier curves or spline curves, by analyzing the control points of the paths, calculate the parametric equations of the curves in three-dimensional space, and further obtain the coordinate values of each segment of the curves; for arc paths, by calculating the positions of the starting point, ending point, and center of the circle, deduce the geometric relationships of the arcs in three-dimensional space; for closed regions, by detecting whether the paths are closed, convert them into a closed two-dimensional region and provide the required planar coordinate information for subsequent three-dimensional modeling. In these calculation processes, the three-dimensional spatial coordinates and shapes of each graphic element are accurately determined, laying a foundation for subsequent three-dimensional modeling.

[0046] S22: According to the shapes of each graphic element in the graphic elements and the graphic design requirements, calculate the thickness and depth parameters of each graphic element in the graphic elements to generate the design parameters of each graphic element in the graphic elements.

[0047] Specifically, according to the design requirements provided by the user, such as the thickness, depth, surface material, etc. of the graphic elements, calculate the specific dimensions and forms of each graphic element in three-dimensional space. For two-dimensional graphic elements, such as rectangles, circles, etc., according to the design requirements, convert them into three-dimensional graphics with depth through mathematical formulas. For example, for a rectangular path, the design requirements may require it to be extruded into a cuboid. During the calculation process, according to the input thickness parameter, each vertex of the rectangle will be pushed along the vertical direction to generate a three-dimensional shape with thickness; for a circular path, it can be stretched along the normal direction into a cylinder. For more complex graphic elements, the depth parameter in the design requirements can determine how to "stretch" or "compress" these graphic elements in three-dimensional space to generate three-dimensional models that meet the requirements. Through these calculations, accurate three-dimensional design parameters can be generated for each graphic element, including information such as thickness, depth, and surface material.

[0048] S23: Based on the three-dimensional spatial coordinates, shapes, and design parameters, use three-dimensional modeling algorithms for transformation to generate an initial three-dimensional model.

[0049] Specifically, in combination with the three-dimensional space coordinates, graphic shapes, and design parameters calculated previously, a three-dimensional modeling algorithm is used to convert two-dimensional graphic elements into a three-dimensional model. Commonly used modeling methods include extrusion modeling, revolution modeling, sweeping modeling, etc. For example, for a closed two-dimensional rectangle, first, according to the thickness information in the design requirements, it is extruded along the normal direction to form a cuboid; for a circular path, according to its radius and the required depth in the design, a cylinder is generated through revolution modeling. For more complex graphics, such as multi-segment curves or complex geometric shapes, the sweeping modeling algorithm may be used to stretch or rotate it along a certain path to form a three-dimensional object. In these steps, the geometric transformation algorithm continuously adjusts and optimizes each graphic element, and finally generates an initial three-dimensional model that meets the design requirements.

[0050] S24: During the conversion of the initial three-dimensional model, Boolean operations are performed for merging and connecting to ensure the complete generation of the initial three-dimensional model.

[0051] Specifically, during the process of generating the initial three-dimensional model, different graphic elements are merged or connected through Boolean operations. These Boolean operations can ensure the correct combination of multiple three-dimensional graphic elements in space. For example, for two overlapping cylinders, they are merged into a complete three-dimensional model through the Boolean addition operation; for the intersection of a rectangle and a circle, the three-dimensional form of the overlapping part of the two graphics is generated through the Boolean intersection operation; for the unnecessary parts, the areas that do not meet the design requirements are removed through the Boolean subtraction operation. In these operations, the connection and merging between geometric elements are precisely executed through mathematical algorithms, ensuring the integrity and accuracy of the initial three-dimensional model, avoiding unnecessary overlaps or voids, and ensuring the reasonable layout and connection of each graphic element in three-dimensional space.

[0052] In one embodiment, as Figure 4 shown, in step S21, that is, the geometric features of each graphic element in the graphic elements are deeply analyzed, and the three-dimensional space coordinates and shapes corresponding to each graphic element in the graphic elements are calculated, specifically including: S211: Calculate the spatial relationships of different types of graphic elements in the graphic elements through geometric derivation, and generate the three-dimensional space coordinates corresponding to each graphic element in the graphic elements.

[0053] Specifically, for each graphic element, such as a straight line, curve, arc, or closed region, its relative position and relationship in three-dimensional space are first calculated through geometric derivation. Taking the straight-line element as an example, by obtaining the starting and ending coordinates of the straight line and using vector operations in linear algebra, the direction and length of this straight line in three-dimensional space are derived; if the path is a curve or arc path, through the control points of the Bezier curve or circular arc, the equation of the curve in three-dimensional space is derived through analytic geometry, thereby calculating the specific three-dimensional space coordinates of each curve or arc. During the calculation process, the spatial trajectory of the entire curve or arc is derived based on the position and angular relationship of the control points; for a closed region, it is determined whether it forms a closed loop by the starting and ending points of the path, and then the region is transformed into a three-dimensional planar region through curve fitting to ensure accurate calculation of the coordinates of each point on the path in three-dimensional space and generate the corresponding three-dimensional coordinate data for this region.

[0054] S212: Use a surface fitting algorithm to calculate each graphic element in the graphic elements and generate the shape of each graphic element in the graphic elements.

[0055] Specifically, for the generation of the shape of each graphic element, a surface fitting algorithm is used to smooth and optimize the form of the path data, such as least squares fitting. Taking a circular path as an example, first, by identifying the control points and radius parameters of the circle, a surface fitting algorithm is used to calculate the smooth curve of this circular path, and by calculating the relationship between this curve and the surrounding environment, its three-dimensional surface is generated. During the curve fitting process, the algorithm matches the path data with the curve equation to minimize the error between all points on the path and the fitted curve, thereby obtaining an optimal curve shape that approximates the path data; for more complex shapes, such as polygons or free curves, polynomial surface fitting or spline curve fitting is used. By adjusting the parameters of the control points and curve segments, it is ensured that the obtained three-dimensional surface meets the requirements of the graphic design and generates a three-dimensional form that meets the design requirements. In this process, the algorithm not only generates a preliminary shape but also performs detailed calculations and optimizations for the specific characteristics of each graphic element, thereby ensuring that the obtained three-dimensional shape meets the actual application requirements and is smooth, continuous, and without mutations.

[0056] In one embodiment, as Figure 5 shown, in step S30, that is, obtaining the editing information of the user and adjusting the initial three-dimensional model according to the editing information to generate a preliminarily adjusted three-dimensional model, specifically including: S31: Obtain the editing information input by the user through the graphic interface. The editing information includes but is not limited to the size, shape, rotation angle, translation distance, material, and texture of the graphic element.

[0057] Specifically, through the graphical interface, the user can input editing information in ways such as input boxes, sliders, and rotation controllers. This information includes the dimensions, shapes, rotation angles, translation distances, materials, and textures of graphic elements. For example, for a rectangular graphic, the user can specify the length and width of the rectangle through an input box or adjust its dimensions through a slider; if it is a circular path, the user can select its radius; in the adjustment of the rotation angle, the user can specify the angle by which the graphic rotates around a certain axis in three-dimensional space through a rotation controller, such as rotating 45 degrees; the translation distance can be set by inputting specific X, Y, and Z coordinate values to determine the new position of the graphic. Materials and textures are specified by selecting preset material options or uploading texture images to decorate the graphic surface and affect its appearance. All this editing information is transmitted to the subsequent geometric transformation algorithm through the graphical interface interaction method to achieve precise three-dimensional model adjustment.

[0058] S32: According to the editing information, perform geometric transformation on the initial three-dimensional model to generate a preliminarily adjusted three-dimensional model.

[0059] Specifically, according to the editing information provided by the user, the initial three-dimensional model will be adjusted through geometric transformation operations. For example, for size adjustment, if the user requests to adjust the length and width of a rectangular model to new values respectively, the scaling factor can be calculated to change the proportion of the rectangle. At this time, the coordinates of each point will be enlarged or reduced accordingly according to the scaling factor to ensure that the shape of the graphic in three-dimensional space meets the new size requirements; if the user specifies a rotation angle, then the system will calculate the rotation change of each graphic element relative to the specified axis according to the rotation matrix. During the rotation process, the coordinates of each point will be calculated with the original coordinates through the rotation matrix to obtain a new position; for the translation operation, through addition operations, the coordinates of each point of the graphic element are increased by the translation amount specified by the user to achieve position movement in three-dimensional space; when the user adjusts the material or texture, this transformation will affect the visual effect of the model surface without changing its geometric shape, and the system will map the new material information to the corresponding graphic surface. Through these geometric transformation operations, the initial three-dimensional model will be gradually adjusted to a state that meets the user's editing requirements, and finally a preliminarily adjusted three-dimensional model will be generated.

[0060] In one embodiment, as Figure 6 shown, in step S40, that is, using augmented reality technology to simulate the preliminarily adjusted three-dimensional model. During the simulation of the preliminarily adjusted three-dimensional model, feedback information is obtained, and according to the feedback information, the preliminarily adjusted three-dimensional model is adjusted for the second time to generate a perfected three-dimensional model, which specifically includes: S41: Use augmented reality technology to render the preliminarily adjusted three-dimensional model into the required scene set by the user.

[0061] Specifically, through augmented reality technology, the preliminarily adjusted 3D model can be virtually superimposed onto the actual scene specified by the user, which is usually achieved through the device's camera or sensors. First, by identifying the user's scene environment, such as obtaining the real-time image of the camera through the device, the system calculates the spatial coordinates of the current scene and places the 3D model at the position specified by the user based on this data. For example, the user can specify the position of the advertising word model in the store window through the touch screen or other input methods, and the augmented reality technology will calculate and adjust the position, angle, and scaling ratio of the 3D model to seamlessly dock it with the real environment, making the model look as if it exists in the actual scene. This process is not just simple rendering, but rather captures and analyzes environmental data in real time through sensors to ensure the accurate coordination of the 3D model with the real-world scene, giving it a real sense of space and perspective effect.

[0062] S42: Analyze the feedback information to generate adjustment parameters for the preliminarily adjusted 3D model, and perform secondary adjustment on the preliminarily adjusted 3D model according to the adjustment parameters. The adjustment parameters include but are not limited to size, shape, position, and material.

[0063] Specifically, the user interacts with the 3D model in the augmented reality scene, such as through zooming, rotating, or touch screen feedback, to provide feedback information about the model, including size, shape, position, and material. For example, the user may find that the size of the 3D model is inappropriate or the color does not match the environment. At this time, the feedback information will reflect these problems. The user can provide specific feedback through the interface, and the system will analyze this feedback information to generate corresponding adjustment parameters. Suppose the user requests to enlarge the model size by 10%, the system will calculate the adjustment ratio and adjust the 3D coordinates and size data of the model; if the user adjusts the position of the model, the feedback information will provide new coordinate data, and based on these new data, the 3D model will be adjusted secondarily in position; if the material needs to be changed, such as from a metal material to a wood grain material, the feedback analysis will determine the material change requirements and reprocess the surface of the 3D model based on the texture mapping algorithm. After generating specific adjustment parameters according to all these analysis results, the model will be precisely adjusted secondarily based on these parameters to finally obtain a perfect 3D model that meets the user's expectations.

[0064] In one embodiment, as Figure 6 shown, in step S50, that is, according to the preset format algorithm, output the perfected 3D model into the file format corresponding to the device, specifically including: S51: Obtain the target device type selected by the user, and determine the target device requirements according to the target device type selected by the user.

[0065] Specifically, the user first selects the target device type through the interface. For example, the user selects a 3D printer, a virtual reality device, an augmented reality device, etc. After the selection is completed, the system will identify its specific requirements according to the device type. For example, if the user selects a 3D printer, the system will automatically identify and determine the corresponding requirements according to the printing capabilities and requirements of the device, such as the supported file formats (such as STL, OBJ), printing accuracy, material type, etc.; if a virtual reality device is selected, it may be necessary to output formats such as GLTF or FBX. The system will determine the required file formats and parameters according to the device's graphics processing capabilities, supported rendering technologies, etc. During this process, the user's selection drives the specific requirements of the target device, and these requirements affect the file format, accuracy, and subsequent processing steps.

[0066] S52: During the output process of the file format, according to the requirements of the target device, apply the preset format algorithm to convert the refined 3D model into the format required by the target device, and generate the file format corresponding to the device.

[0067] Specifically, after obtaining the device requirements, the file format conversion process applies the preset format algorithm according to the requirements supported by the device. For example, for a 3D printer, if the target device requires the STL format, the algorithm will convert the data of the 3D model into a format that conforms to the STL standard according to the requirements of the STL file format. This includes dividing the 3D model into multiple triangular patches and accurately calculating the coordinate points, normal vectors, etc. of each patch to ensure the accuracy and structural stability of the 3D model during printing; for a virtual reality device, if it is required to output the GLTF format, the preset algorithm will convert the 3D model into the node, material, and animation data structures of the GLTF format to ensure that the model can be correctly rendered and interacted in the virtual reality environment; during this process, the format algorithm will automatically adjust and convert the structure of the file by parsing the geometric data of the 3D model, remove redundant data, compress the file size, while retaining the visual effect and geometric accuracy of the model, and finally generate the file format that meets the requirements of the target device.

[0068] It should be understood that the magnitudes of the sequence numbers of the steps in the above embodiments do not mean the order of execution. The order of execution of each process should be determined according to its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.
