Description

Technical Field

[0001] This invention relates to the field of card technology, and in particular to an immersive naked-eye 3D animation effect display system. Background Technology

[0002] Currently, in the field of card collecting and display, traditional interactive methods are mostly limited to appreciating the patterns on the cards themselves or simply scanning QR codes to view two-dimensional information, lacking a deep sense of immersion and visual impact.

[0003] Although naked-eye 3D display technology can provide a stereoscopic visual experience without the need for auxiliary equipment, existing naked-eye 3D content generation and display systems usually rely on local high-performance graphics workstations for real-time rendering, resulting in high overall hardware costs and complex deployment. This makes it difficult to achieve low-cost, deep integration and interaction with lightweight and widely available physical media such as physical cards, thus limiting its application expansion in mass consumer scenarios. Summary of the Invention

[0004] This invention provides an immersive naked-eye 3D animation effect display system to solve existing technical problems, and solves the problem of low-cost and deep integration and interaction with lightweight and popular physical media such as physical cards.

[0005] To solve the above-mentioned technical problems, according to one aspect of the present invention, more specifically, an immersive naked-eye 3D animation effect display system is provided, comprising:

[0006] A card, wherein the card has readable identification information;

[0007] The card recognition module is used to read the identification information on the card;

[0008] The cloud server stores naked-eye 3D effect animation resources that correspond one-to-one with multiple different identifiers.

[0009] An animation parsing and loading module is communicatively connected to the card recognition module and the cloud server. It is used to send the identification information to the cloud server and receive naked-eye 3D effect animation resources that match the identification information returned from the cloud server.

[0010] The multi-view rendering module, connected to the animation parsing and loading module, is used to perform multi-path rendering of the naked-eye 3D effect animation resources to generate an image sequence that meets the requirements of naked-eye 3D display.

[0011] A glasses-free 3D display module, connected to the multi-viewpoint rendering module, is used to display the rendered glasses-free 3D animation;

[0012] The naked-eye 3D effect animation resource is a complete animation file that is pre-generated and stored in the cloud server.

[0013] Furthermore, the identification information is NFC chip information or QR code / barcode information.

[0014] Furthermore, the card recognition module includes an NFC reader or image capture device for contactless reading of the identification information.

[0015] Furthermore, the naked-eye 3D effect animation resources stored in the cloud server are animation files containing multiple viewpoint image data, created based on a pre-built 3D model through animation editing, lighting rendering, and parallax mapping processes.

[0016] Furthermore, the animation parsing and loading module is specifically used for:

[0017] Generate a resource request based on the identification information;

[0018] The resource request is sent to the cloud server to query the storage address of the naked-eye 3D effect animation resource associated with the identification information;

[0019] The corresponding naked-eye 3D effect animation resource file is obtained from the cloud server according to the storage address.

[0020] Furthermore, the animation parsing and loading module is also used to adapt the format or resolution of the animation resource according to the hardware parameters of the naked-eye 3D display module when loading the naked-eye 3D effect animation resource.

[0021] Furthermore, the immersive naked-eye 3D animation effect display system also includes a user account module, which is used to bind the card's identification information to a specific user account. The cloud server provides corresponding naked-eye 3D effect animation resources or records resource usage logs based on the user account information.

[0022] Furthermore, the immersive naked-eye 3D animation effect display system also includes a positioning module, used to determine the physical position of the card placed within the recognition area of ​​the card recognition module;

[0023] The multi-view rendering module controls the display position of the rendered naked-eye 3D animation on the naked-eye 3D display module according to the physical position, so that the naked-eye 3D animation appears to be floating above or associated with the card.

[0024] This invention provides an immersive naked-eye 3D animation effect display system. Compared with existing technologies, the effects achieved by this method are as follows:

[0025] 1. This invention significantly reduces the reliance on local hardware performance by placing complex 3D rendering and animation generation tasks in the cloud for preprocessing. This enables the system to achieve smooth display of high-quality naked-eye 3D content on low-cost, ordinary-configuration terminals, which is conducive to the popularization and application of this technology in commercial displays, education and entertainment scenarios.

[0026] 2. This invention uses physical cards as an interactive medium, combined with cloud resource scheduling and local multi-view rendering technology, so that users can watch a three-dimensional animation that seems to float out from above the card without wearing any auxiliary equipment, creating an immersive visual experience and enhancing the fun and immersion of the interactive process.

[0027] 3. This invention centrally stores and manages animation resources in the cloud. The system realizes unified maintenance, dynamic updates and copyright protection of content. Operators can add or replace animation materials at any time, and users can continuously obtain fresh content without replacing physical cards or upgrading their local system, thus improving the sustainability and service flexibility of the system.

[0028] 4. This invention innovatively links physical cards with digital 3D animation in spatial location and supports multiple card combinations to trigger specific animations, realizing deep linkage between physical media and virtual content, and providing a novel and attractive technical solution for applications such as card collection, interactive storytelling, and scene-based display. Attached Figure Description

[0029] Figure 1 This is a schematic diagram of the structure of the present invention. Detailed Implementation

[0030] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figure 1 The diagram shown is a structural block diagram of an immersive naked-eye 3D animation effect display system according to the present invention. The system mainly includes: cards, a card recognition module, a cloud server, an animation parsing and loading module, a multi-viewpoint rendering module, and a naked-eye 3D display module. Optionally, the system also includes a user account module and a positioning module.

[0032] Cards serve as the physical medium for user interaction. They are imbued with identification information, which acts as the card's unique "identity ID" in the digital world. In a preferred embodiment of this invention, the cards are "Ultraman cards," with each different Ultraman character card (such as Ultraman Zero or Ultraman Tiga) corresponding to a unique identification information. The identification information can be implemented in ways including, but not limited to, a Near Field Communication (NFC) chip integrated within the card, or a QR code or barcode printed on the card's surface. NFC chips offer advantages such as contactless operation, fast reading speed, and encrypted information; QR codes / barcodes offer advantages such as low cost and ease of mass printing.

[0033] The card recognition module is responsible for sensing and reading the identification information on the cards. Its specific implementation depends on the type of identification information.

[0034] If the identification information is NFC chip information, then the card recognition module is an NFC reader / writer. When the card is brought close to the sensing area of ​​the NFC reader / writer (usually a specific marked location on the system base), the reader / writer reads the unique ID code stored in the chip non-contactly through the principle of electromagnetic induction.

[0035] If the identification information is a QR code / barcode, then the card recognition module is an image acquisition device (such as a camera). When the user places the card in the recognition area, the camera captures the surface of the card, and the information contained in the QR code / barcode is parsed using an image recognition algorithm (such as the OpenCV library).

[0036] After reading the identification information, this module converts it into a digital signal and outputs it to subsequent modules.

[0037] The cloud server is the core data storage and scheduling center of this system. It stores a vast library of naked-eye 3D animation resources. Each animation file in the library is precisely bound to one or more card identification information. For example, a card with the identification information "ULTRA-001" corresponds to a resource file named "Ultraman Zero_Ultimate Shining Type Naked-Eye 3D Display Animation.mp4" on the cloud server.

[0038] These animation resources are not generated locally in real time, but are pre-generated complete files stored in the cloud. Their production process is independent of this presentation system and typically includes:

[0039] 1) Use software such as Maya and Blender to create high-precision 3D models of Ultraman characters;

[0040] 2) Bind the skeleton to the model and design a series of display actions (such as entrance close-ups and skill releases);

[0041] 3) Set lighting and materials in the virtual scene for high-quality rendering;

[0042] 4) The most crucial step, based on the principle of multi-view naked-eye 3D imaging, involves rendering images of the same frame from multiple specific perspectives (such as 9-viewpoint or 16-viewpoint) using rendering engines (such as Unity or Unreal Engine) or dedicated algorithms. These images are then encoded and synthesized into a special video file (such as a multi-viewpoint video stream or raster composite image) conforming to the naked-eye 3D format. Therefore, the animation files stored in the cloud are composite data packets containing temporal sequence and multi-viewpoint spatial information.

[0043] The animation parsing and loading module serves as a bridge connecting local hardware and cloud resources. Logically, this module can be a software unit integrated into the local device (such as the built-in host of the demonstration stand). Its workflow is as follows:

[0044] Receiving and Requesting: Receives identification information from the card recognition module. Then, generates a structured resource request data packet based on this information, which includes at least the identification information and the authentication information of the local device.

[0045] Network communication: Sending resource requests to a specified API interface of a cloud server via the Internet.

[0046] Resource matching and acquisition: After receiving a request, the cloud server queries its database for the storage address (such as a URL) of the animation resource associated with the identifier information. Then, it streams or downloads the corresponding naked-eye 3D effect animation resource file to the local machine via a content delivery network (CDN) or direct transmission.

[0047] Parsing and Adaptation: After receiving the animation file, the animation parsing and loading module first parses it, reading the file header information to confirm parameters such as format, encoding, resolution, and number of viewpoints. Next, it performs adaptation processing based on the hardware parameters of the naked-eye 3D display module. For example, if display module 6 is a 9-viewpoint lenticular lens screen, and the animation resource is in 16-viewpoint format, the module needs to call the embedded viewpoint conversion algorithm to adapt the 16-viewpoint data to 9-viewpoint data. Alternatively, if the display module's resolution is 4K, but the animation resource is 2K, the animation parsing and loading module can call a super-resolution algorithm for image quality enhancement or perform intelligent scaling to avoid distortion.

[0048] The multi-view rendering module receives adapted animation data from the animation parsing and loading module. Its core task is to perform multi-path rendering. This "rendering" differs from real-time rendering in computer graphics; it primarily involves the final "compositing and mapping" rendering of the already rendered multi-view image sequence. Specifically:

[0049] The multi-view rendering module reads animation data frame by frame in a time sequence. Each frame contains sub-images captured from N different viewpoints.

[0050] The multi-view rendering module applies a multi-view sub-pixel mapping algorithm based on the optical structural parameters of the naked-eye 3D display (such as lens pitch, tilt angle, and sub-pixel arrangement). This algorithm calculates which viewpoint sub-image each RGB sub-pixel on the screen should extract its color value from in the current frame, and sometimes even requires interpolation calculations from images of two adjacent viewpoints to generate a smooth transition effect.

[0051] Ultimately, the naked-eye 3D display module outputs a special sequence of images that meets the optical requirements of the naked-eye 3D display screen and can directly drive it. If the system includes a positioning module (such as through a camera combined with image recognition, or by deploying a pressure sensor array under the recognition area), this module can detect the precise physical coordinates (X, Y) of the card's placement. The multi-view rendering naked-eye 3D display module incorporates this coordinate information into its calculations, dynamically adjusting the content of its output image sequence so that the "visual position" of the 3D animation ultimately presented on the screen is correlated with the physical position of the card. For example, it can make Ultraman's 3D image appear to rise precisely above the card, achieving an augmented reality (AR) visual effect of "animation floating above the card."

[0052] The glasses-free 3D display module is the system's output terminal, typically a lenticular (lens or slit grating) glasses-free 3D display screen. It receives and displays image sequences generated by the multi-viewpoint rendering glasses-free 3D display module. Because the image sequence has undergone precise optical mapping processing, when a user stands in front of the screen, their left and right eyes receive pixels from sub-images at different viewpoints. The brain fuses these two images with subtle parallax, creating a strong sense of depth and allowing the user to observe Ultraman 3D animation floating on the screen, without wearing any 3D glasses.

[0053] The user account module is an optional value-added service module. Users can register an account through a mobile app or a display system terminal and bind the identification information 11 of their owned card 1 to the account. This brings the following benefits:

[0054] 1) Personalization: The cloud server can provide customized animations based on account information, such as displaying the subtitle "Welcome [Username]" before Ultraman animation plays.

[0055] 2) Digital Collections and Logs: The system records every card use and animation playback, forming a digital collection record for the user.

[0056] 3) Social and Updates: Users can unlock special animations based on card combinations or receive animation updates pushed from the cloud (such as new Ultraman forms).

[0057] Example 1: Display of Ultraman Individual Cards

[0058] The user places a "Ultraman Zeta" card (with a built-in NFC chip, ID: "ZETT-003") on the recognition area of ​​the display stand. The card recognition module (NFC reader / writer) reads the ID. The animation parsing and loading module sends the ID to the cloud server. The cloud server finds that the ID "ZETT-003" corresponds to the "Ultraman Zeta_Alpha Armor Form Display Animation" file and streams that file to the local machine. The animation parsing and loading module detects that the local naked-eye 3D display module is a 9-viewpoint 4K screen, while the animation resource is a 16-viewpoint 2K screen, so it performs viewpoint conversion and super-resolution adaptation. The processed data is sent to the multi-viewpoint rendering naked-eye 3D display module, which performs sub-pixel mapping rendering based on the screen parameters.

[0059] Finally, on the naked-eye 3D display module, users can watch a stunning 3D animation of Ultraman Zeta, in his iconic Alpha Armor form, spinning out from the card position and making a fighting pose in the air. The animation is vibrant in color, has a clear depth effect, and is highly immersive.

[0060] Example 2: Multi-player interaction and card combination display

[0061] The system supports multiple recognition areas. Two users placed their "Ultraman Taro" card and "Mother of Ultra" card into two different recognition slots. The positioning module accurately pinpointed the positions of the two cards. After the system recognized the two cards, the animation parsing and loading module requested a special "combination animation" from the cloud server. The cloud server found that IDs "TARO-006" and "MOTHER-001" met the combination conditions, and thus sent a unique 3D animation of "Mother and Son Ultraman's Joint Beam." The multi-view rendering naked-eye 3D display module rendered and "anchored" the 3D images of Ultraman Taro and Mother of Ultra above their respective cards based on their positions, and then played the combined animation of them firing beams together, realizing a dynamic spatial narrative based on the physical card positions.

[0062] Example 3: User Account Linked Display

[0063] The logged-in user "Xiaoguang" placed their account-linked "Ultraman Zero Infinite Form" card in the recognition area. After the system recognized the card ID, the animation parsing and loading module requested basic animation resources from the cloud, along with the user's account information. Before returning the standard animation, the cloud server first pushed a short voice-over subtitle customized for the user: "Xiaoguang, Zero Infinite Form, unlocked!" This subtitle was integrated into the animation's opening in 3D. Simultaneously, this playback was recorded in "Xiaoguang's" account's collection log, accumulating points.

[0064] In summary, the immersive naked-eye 3D animation effect display system provided by this invention significantly reduces local computing load and hardware costs through the core architecture of "binding physical card identifiers to cloud-based pre-rendered 3D animation resources": complex 3D modeling, lighting and shadow rendering, and disparity map generation and other heavy computing tasks are pre-processed in the cloud, and local devices only need to perform resource loading, format adaptation, and final optical compositing rendering, which enables the system to be deployed on terminals with relatively low performance requirements, thus lowering the threshold for popularization.

[0065] It achieves centralized management and dynamic updates of animation resources: all animation resources are stored in the cloud for unified management, encryption, and copyright protection. Production teams can update, replace, or add animation content at any time, and users can experience the latest content without changing cards or upgrading their local devices.

[0066] It ensures a high-quality naked-eye 3D visual experience: cloud pre-rendering can utilize high-performance computing clusters to produce multi-view animations with cinematic quality, and the level of detail and smoothness of its visual effects is far superior to local real-time rendering solutions.

[0067] It creates an immersive interactive experience that deeply integrates the physical and digital worlds: using cards as a familiar physical medium as an entry point, combined with precise positioning and spatial mapping technology, it links cool naked-eye 3D animations with the location of physical cards, providing users with an intuitive, magical, and fun interactive experience that transcends the scope of traditional screen displays.

[0068] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
