[0015] Digital images on digital space platforms that have been certified through a multi-party joint registration and certification mechanism for digital images will be used as shared digital images.

[0016] In one embodiment, the method further includes:

[0017] When a user logs into the digital space platform with their account but the digital space platform has not yet enabled digital avatar sharing management, the registration process of the multi-party joint registration and authentication mechanism for digital avatars determines whether the user will share and manage the digital avatars in the digital space platform.

[0018] When a user account decides to share and manage a digital avatar in a digital space platform, a digital avatar sharing management key is generated; the digital avatar sharing management key is used for user authentication when managing digital avatars on various digital space platforms.

The shared digital avatars are those used in multiple digital space platforms associated with a user's account; these multiple digital space platforms are digital space platforms other than the virtual branch. Based on the digital space scene characteristics, usage statistics, and digital avatar description information, a recommended digital avatar is determined from among the shared digital avatars. The user account is then recommended to use the recommended digital avatar in the virtual branch. Thus, shared digital avatars from other digital space platforms can be used, solving the problems of limited, monotonous, and simple digital avatars in the virtual branch, enriching the digital avatar resources of the virtual branch. Simultaneously, by combining the digital space characteristics of the user's virtual branch, the usage statistics of shared digital avatars, and the digital avatar description information, accurate recommendations of shared digital avatars can be made for the user.

[0046] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0047] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this disclosure are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure.

[0048] The digital image recommendation method provided in this application can be applied to, for example... Figure 1 In the application environment shown, terminal 102 communicates with server 104 via a network. A data storage system can store the data that server 104 needs to process. The data storage system can be integrated onto server 104 or located on a cloud or other network server. In response to a digital image recommendation request initiated by a virtual business hall for handling financial transactions, server 104 obtains the digital space scene characteristics of the virtual business hall, usage statistics for each shared digital image, and digital image description information. The shared digital image refers to a digital image used for shared use on multiple digital space platforms associated with a user account. These multiple digital space platforms are digital space platforms other than the virtual business hall. Based on the digital space scene characteristics, usage statistics, and digital image description information, server 104 determines the recommended digital image among the shared digital images. Server 104 recommends the user account to use the recommended digital image in the virtual business hall. The user of terminal 102 can use the recommended digital image recommended to their account by server 104 as the digital image for the virtual business hall. The terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices can include smart speakers, smart TVs, smart air conditioners, and smart in-vehicle systems. Portable wearable devices can include smartwatches, smart bracelets, and head-mounted devices. The server 104 can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0049] In one embodiment, such as Figure 2 As shown, a digital image recommendation method is provided, which is then applied to... Figure 1 Taking server 104 as an example, the following steps are included:

[0050] Step S202: In response to the digital image recommendation request initiated by the virtual business hall for handling financial business, obtain the digital space scene characteristics of the virtual business hall, usage statistics and digital image description information corresponding to each shared digital image; the shared digital image is a digital image used for sharing in multiple digital space platforms associated with the user account; the multiple digital space platforms are digital space platforms other than the virtual business hall.

[0051] Financial services can include services such as deposits, withdrawals, and loans that users receive from banks.

[0052] Among them, a virtual branch can be a bank's three-dimensional digital branch. This refers to a digital branch created by the bank based on the characteristics of metaverse immersive experience, digital identity, and virtual-real integration. It fully utilizes digital interaction technology, digital spatial modeling technology, and digital human technology to create a three-dimensional digital space with functions such as guided tours, immersive interaction, product marketing, and simple business processing. It is a type of three-dimensional digital space. Furthermore, a three-dimensional digital space can be a virtual space rendered by a 3D engine using digital interaction, digital spatial modeling, and digital human technologies, possessing functions such as tours, interactions, games, and social interaction.

[0053] Among them, the digital avatar can be a virtual avatar provided by the bank to users in the bank's three-dimensional digital branch, which users can control to be displayed, moved, and interacted with.

[0054] Among them, the digital avatar recommendation request can be a request made by a user when logging into the virtual business hall to select a digital avatar, which is used to request a digital avatar recommendation.

[0055] Among them, digital space scene characteristics can be the typical appearance characteristics of digital space.

[0056] Among them, a shared digital avatar can be a digital avatar that can be used on multiple platforms.

[0057] Among them, usage statistics can include the usage and sharing of digital avatars selected by user accounts, which can reflect user preferences.

[0058] Among them, the digital image description information can be the information obtained by describing the characteristics of the digital image.

[0059] The user account can be an account that the user registered in the virtual business hall.

[0060] Among them, digital space platforms can be game digital space platforms, banking digital space platforms, social digital space platforms, etc.

[0061] In practice, the server responds to the digital image recommendation request initiated by the virtual business hall for handling financial business, and obtains the digital space scene characteristics of the virtual business hall, the usage statistics of user accounts when using each shared digital image, and the digital image description information corresponding to each shared digital image.

[0062] Step S204: Based on the characteristics of the digital space scene, usage statistics, and digital image description information, determine the recommended digital image from among the shared digital images.

[0063] Among them, the recommended digital avatar can be the digital avatar with the highest recommendation rate for the user account.

[0064] In practice, the server determines the most likely shared digital image for the user to use, i.e., the recommended digital image, based on the digital space scene characteristics of the virtual business hall, the usage statistics of the user account when using each shared digital image, and the digital image description information corresponding to each shared digital image.

[0065] The server combines digital space scene characteristics, usage statistics, and digital image descriptions to obtain a shared digital image recommendation ranking through semantic correlation collaborative recommendation, which users can then choose to use in the virtual business hall.

[0066] Specifically, the server recommends digital avatars based on statistical data about user preferences and the characteristics of the avatars within their target digital spaces. It then retrieves the relevant avatar modeling files based on the user's final selection and renders them in the virtual banking hall for user interaction. For example, if a user uploads a realistic humanoid avatar from a social digital space platform and a cartoon-style avatar from a game digital space platform, the system will initially recommend realistic humanoid avatars during the first few logins to the bank's virtual banking hall. However, if the user repeatedly uses cartoon-style avatars, the system will subsequently recommend cartoon-style avatars based on the user's preferences.

[0067] Step S206: Recommend user accounts to use the recommended digital avatar in the virtual business hall.

[0068] In practice, the server recommends that user accounts use a recommended digital avatar in the virtual business hall.

[0069] In the aforementioned digital avatar recommendation method, in response to a digital avatar recommendation request initiated by a virtual branch for handling financial transactions, the method obtains the digital space scene characteristics of the virtual branch, usage statistics of each shared digital avatar, and digital avatar description information. Shared digital avatars are those used across multiple digital space platforms associated with a user's account. These multiple digital space platforms are those other than the virtual branch. Based on the digital space scene characteristics, usage statistics, and digital avatar description information, a recommended digital avatar is determined from among the shared digital avatars. The recommended digital avatar is then recommended for the user's account to use in the virtual branch. This method utilizes shared digital avatars from other digital space platforms, addressing the issues of limited, monotonous, and simplistic digital avatars in the virtual branch, thus enriching the digital avatar resources of the virtual branch. Furthermore, by combining the digital space characteristics of the user's virtual branch, the usage statistics of shared digital avatars, and digital avatar description information, the method accurately recommends shared digital avatars to the user.

[0070] In another embodiment, the method further includes: when a user account selects to use a recommended digital avatar in a virtual business hall, determining the digital avatar model data corresponding to the recommended digital avatar; and using the rendering engine of the virtual business hall to load the digital avatar model data in the virtual business hall to render the recommended digital avatar.

[0071] Among them, the digital image model data can be the three-dimensional model data corresponding to the digital image.

[0072] The rendering engine can be Blender (an open-source, cross-platform, all-in-one 3D animation production software), Unity (a real-time 3D interactive content creation and operation platform), Unreal Engine (a game engine), etc.

[0073] In practice, when a user account selects to use the recommended digital avatar in the virtual business hall, the server determines the digital avatar model data corresponding to the recommended digital avatar. Among them, the digital avatar model data is most compatible with the rendering engine type of the virtual business hall. The server uses the rendering engine of the virtual business hall to load the digital avatar model data in the virtual business hall so as to render the recommended digital avatar in the virtual business hall.

[0074] The technical solution of this embodiment determines the digital image model data corresponding to the recommended digital image when the user account selects to use the recommended digital image in the virtual business hall; it uses the rendering engine of the virtual business hall to load the digital image model data in the virtual business hall to render the recommended digital image; in this way, the most suitable digital image model data can be determined to be loaded in the virtual business hall according to the rendering engine type of the virtual business hall, realizing the cross-platform sharing and application of digital images.

[0075] In another embodiment, the method further includes: establishing a multi-party joint registration and authentication mechanism for digital images; the multi-party joint registration and authentication mechanism for digital images is used to share digital images in the digital space platform across platforms; and digital images on the digital space platform that have been certified through the multi-party joint registration and authentication mechanism for digital images are used as shared digital images.

[0076] Among them, the digital image multi-party joint registration and certification mechanism can be a certification mechanism that unites multiple digital space platforms, enabling digital images to be shared among digital platforms certified through this mechanism.

[0077] In practice, the server establishes a multi-party joint registration and authentication mechanism for digital images, and uses digital images on the digital space platform that have been certified through this mechanism as shared digital images.

[0078] The technical solution of this embodiment establishes a multi-party joint registration and authentication mechanism for digital images. This mechanism is used to share digital images across digital space platforms. Digital images on digital space platforms that have been certified through the multi-party joint registration and authentication mechanism are used as shared digital images. In this way, the digital images of user accounts on various digital space platforms can be shared and reused, solving the problem of the lack of digital images in virtual business halls, enriching the digital images that can be displayed in virtual business halls, and improving the development efficiency of virtual business halls.

[0079] In another embodiment, the method further includes: when a user account logs into a digital space platform and the digital space platform has not yet enabled digital image sharing management, determining whether the user will share and manage the digital image in the digital space platform through a registration process of a multi-party joint registration and authentication mechanism for digital images; when the user account confirms that it will share and manage the digital image in the digital space platform, generating a digital image sharing management key; the digital image sharing management key is used for user authentication when managing digital images on various digital space platforms.

[0080] Digital avatar sharing management can include specific operations such as collecting, managing, storing, converting, and sharing digital avatars.

[0081] The registration process can be a process that displays an information registration interface to users to determine whether they need to activate digital image sharing management.

[0082] The digital image sharing management key can be the key obtained by the user after activating digital image sharing management.

[0083] In practice, when a user logs into the digital space platform and the digital space platform has not yet enabled digital avatar management, the server asks the user whether to share and manage the digital avatar in the digital space platform through the registration process of the multi-party joint registration and authentication mechanism for digital avatars. If the user confirms that the digital avatar in the digital space platform will be shared and managed, the server generates a digital information management shared key. When the user subsequently manages the digital avatar on various digital space platforms, they can use this key for authentication. After successful authentication, the user can manage the digital avatar.

[0084] The technical solution of this embodiment determines whether a user will share their digital image on the digital space platform when the user account logs into the digital space platform but the digital space platform has not yet enabled digital image sharing management. This is achieved through a registration process using a multi-party joint registration and authentication mechanism for digital images. If the user account confirms that it will share their digital image on the digital space platform, a digital image sharing management key is generated. This key is used for user authentication when managing digital images on various digital space platforms. In this way, based on the multi-party joint registration and authentication mechanism for digital images, the registration process can be flexibly sent to users, and digital images can be shared quickly, allowing user accounts to quickly gain the authority to manage digital images.

[0085] In another embodiment, the method further includes: obtaining digital avatar model files uploaded by user accounts from various digital space platforms; authentication by any digital space platform through a multi-party joint registration and authentication mechanism for digital avatars; the digital avatar model files are model files used to render the corresponding digital avatars on various digital space platforms; and converting the digital avatar model files into digital avatar model data suitable for various digital space platforms and storing them.

[0086] Among them, the digital image model file can be a three-dimensional model file corresponding to the digital image.

[0087] In practice, the server obtains the digital avatar model files uploaded by the user account from various digital space platforms, then converts the digital avatar model files into digital avatar model data applicable to each digital space platform and stores them.

[0088] In practical applications, the server can count and categorize the digital avatar model files uploaded by users for storage. To ensure the shared digital avatars have high versatility, the server needs to adapt and convert the uploaded digital avatar's engine type to common mainstream engines such as Blender, Unity, and Unreal Engine, and then save the converted data. This improves compatibility when sharing and using the avatar across different digital space platforms. The adaptation and conversion includes file format adaptation, material adaptation, and animation adaptation, and is also associated with the target engine type and mapped to the corresponding digital avatar.

[0089] The technical solution of this embodiment obtains digital avatar model files uploaded by user accounts from various digital space platforms; each digital space platform is certified through a multi-party joint registration and authentication mechanism for digital avatars; the digital avatar model files are model files used to render the corresponding digital avatars on various digital space platforms; the digital avatar model files are converted into digital avatar model data suitable for various digital space platforms and stored; in this way, the engine type of the uploaded digital avatar can be adapted and converted to the model data of the mainstream engine and saved, improving the compatibility when the digital avatar is shared and used between different digital space platforms in the future.

[0090] In another embodiment, the method further includes: when the digital image model data cannot be exported in a common data format by the digital space platform, using a 3D model format conversion tool to convert the digital image model data to a common data format to obtain converted common model data; and exporting the converted common model data from the 3D model format conversion tool.

[0091] Among them, the general data format can be a 3D model data format that can be applied to different digital space platforms.

[0092] Among them, 3D model format conversion tools can be libraries and tools such as Assimp (a library for loading and processing geometric scenes from various 3D data formats), Open3D (an open-source library that supports rapid development and processing of 3D data), and Blender (a permanently open-source and free 3D creation software that supports the entire 3D creation process: modeling, sculpting, skeleton assembly, animation, simulation, real-time rendering, compositing, and motion tracking, and can be used for video editing and game creation).

[0093] The converted general model data can be model data that can be loaded on various digital space platforms.

[0094] In practice, when the digital image model data cannot be exported in a common data format from the digital space platform, the server uses a 3D model format conversion tool to convert the digital image model data into a common data format, and then exports the converted common model data from the 3D model format conversion tool.

[0095] The technical solution of this embodiment, when the digital image model data cannot be exported in a universal data format from the digital space platform, uses a 3D model format conversion tool to convert the digital image model data into a universal data format, obtaining the converted universal model data; the converted universal model data is then exported from the 3D model format conversion tool; in this way, the digital image model data can be quickly converted when the digital space platform cannot export the digital image model data in a universal data format, improving the convenience and applicability of digital image sharing.

[0096] To facilitate understanding by those skilled in the art, the following exemplifies an operation a user can perform on a digital space platform after uploading a digital avatar. Specifically, after obtaining authentication through a multi-party joint registration and authentication mechanism on a digital space platform, the user chooses to upload and share the digital avatar from this platform. The following method is required for digital avatar collection:

[0097] The system uses the relatively universal OBJ format for 3D model files and a common interface for uploading. This interface includes mesh data, materials, textures, maps, rotation, scaling, engine type and version, and a description of the model's characteristics. It also reserves space for details such as the head, face, hair ornaments, body, and clothing to support more detailed model uploads. If the upload platform cannot export to the universal format, libraries and tools such as Assimp, Open3D, and Blender are used to read and process digital image model data in different formats, converting and then exporting the data to a universal model data format.

[0098] During the upload process, key encryption must be used to ensure the privacy of the digital avatar model data.

[0099] In addition, the server also provides a B / S architecture client for users to manage their uploaded digital avatars after authentication and login on the digital space platform. Management includes front-end operations and back-end statistics. The front-end provides users with thumbnail browsing functionality and allows naming and description features, including the avatar's origin, characteristics, and advantages, such as describing an anime character from a game platform as cute. The back-end statistics track user selection, usage, and sharing of digital avatars, reflecting user preferences. Both the digital avatar descriptions and statistics can provide a basis for recommendation and ranking when using digital avatars in the future.

[0100] In another embodiment, the method further includes: in response to a user account's modification operation on the digital image description information of a digital image on a digital space platform, obtaining the modification content corresponding to the modification operation; and updating the digital image description information of the digital image based on the modification content.

[0101] Among them, the operation of modifying the description information of a digital image can be the operation corresponding to modifying the description information of a digital image.

[0102] The modifications can include changes to the digital image's origin, characteristics, advantages, and other aspects.

[0103] In practice, the server responds to the user account's modification operation on the digital image description information on the digital space platform, obtains the modification content corresponding to the modification operation, and updates the digital image description information of the digital image according to the modification content.

[0104] The technical solution of this embodiment responds to the user account's modification operation on the digital image description information of the digital image on the digital space platform, obtains the modification content corresponding to the modification operation, and updates the digital image description information of the digital image according to the modification content. In this way, the description information of the digital image can be modified flexibly, thereby improving the convenience of sharing and managing digital images.

[0105] For the convenience of those skilled in the art, Figure 3 An exemplary method for cross-platform sharing and recommendation of user digital images in a bank's 3D digital branch is provided, which includes four functional modules: "Digital Image Registration and Authentication Module 301", "Digital Image Acquisition and Management Module 302", "Digital Image Storage and Conversion Module 303", and "Digital Image Sharing and Application Module 304".

[0106] The main interaction process between the four functional modules is as follows: The Digital Image Registration and Authentication Module 301 provides joint user registration and authentication functions for various digital space platforms. After obtaining registration and authentication through this method, each digital space platform exports the digital image's modeling, materials, textures, and mapping files, and calls the "Digital Image Acquisition and Management Module 302" to upload the relevant model files and dynamic video files, saving them in the "Digital Image Storage and Conversion Module 303". Users log in to the "Digital Image Acquisition and Management Module 302" provided by this method to manage the digital images uploaded from different platforms, including digital image model files and their descriptions of the image's characteristics and the characteristics of the corresponding digital space, providing a basis for digital image recommendations in the "Digital Image Sharing and Application Module 304". The "Digital Image Storage and Conversion Module 303" provides digital image storage functions for both the "Digital Image Acquisition and Management Module 302" and the "Digital Image Sharing and Application Module 304", storing textures, skeletons, materials, and related animation data files in common model formats such as OBJ. The "Digital Image Sharing Application Module 304" provides users with a digital image recommendation and sharing application function on multiple digital space platforms. It recommends digital images based on the user's preferences for digital images, the characteristics of digital images and the characteristics of the digital space scene, and retrieves the relevant digital image modeling file according to the user's final selection, renders it on the target digital space platform, and makes it available for user operation.

[0107] Specifically, the digital image registration and authentication module 301 includes, for example, the following: Figure 4 The diagram shows a user joint registration unit and a user joint authentication unit. The user joint registration unit is triggered when a user logs into a digital space platform that has adopted the cross-platform sharing and recommendation method for digital avatars. After registering and obtaining a key, the user can collect, manage, store, convert, and share their digital avatar on other digital space platforms that have adopted the same method. The user can subsequently authenticate their identity through the user joint authentication unit to log in to the digital space platform and manage their digital avatar.

[0108] Digital Image Acquisition and Management Module 302, this module includes, for example: Figure 5The diagram shows a digital avatar acquisition unit and a digital avatar management unit. After a user obtains authentication on a digital space platform, they select the digital avatar to be uploaded from that platform, which then invokes the digital avatar acquisition unit to upload the relevant model files. The upload uses the relatively universal 3D model file OBJ format and a common interface. This interface includes mesh data, materials, textures, mapping, rotation, scaling, engine type and version, and model descriptions, and reserves space for more detailed model uploads such as heads, faces, hairstyles, bodies, and clothing. If the upload platform cannot export to the universal format, libraries and tools such as Assimp, Open3D, and Blender are used to read and process model data in different formats, converting them before exporting to the universal model format. Furthermore, key-encrypted transmission is used during the upload process to ensure the privacy of the avatar data. The digital avatar management unit provides a B / S architecture client for users to manage their uploaded digital avatars across multiple platforms after authentication and login. Management includes front-end operations and back-end statistics. The front-end provides users with thumbnail browsing functionality, along with naming and description features. The description function allows users to describe the digital avatar's origin, characteristics, and advantages; for example, describing the digital avatar as "a cute anime character from a game platform." The back-end statistics track user selection, usage, and sharing of digital avatars, reflecting user preferences. Both the digital avatar descriptions and statistics can provide a basis for recommendation and sorting when using digital avatars in the subsequent "Digital Avatar Sharing Application Module 4."

[0109] Digital image storage and conversion module 303, which includes, for example: Figure 6 The diagram shows a digital avatar storage unit and a digital avatar conversion unit. The digital avatar storage unit provides storage management functions for the "Digital Avatar Acquisition and Management Module 2" and the dynamic video data of the models that need to be converted. It can map and categorize user digital avatar models for storage. The digital avatar conversion unit, to ensure high versatility of shared digital avatars, will adapt and convert the model data for common mainstream engines such as Blender, Unity, and Unreal Engine based on the engine type of the uploaded digital avatar in the background and save it, thereby improving compatibility when sharing and using it across different platforms. The adapted and converted content includes file format adaptation, material adaptation, animation adaptation, etc., and is simultaneously mapped and stored in the corresponding digital avatar along with the target engine type.

[0110] Digital Image Sharing Application Module 304, this module includes, for example: Figure 7The diagram illustrates a digital avatar recommendation unit and a digital avatar sharing application unit. When a user selects another digital space platform to share their digital avatar on the target digital space platform, the target digital space platform invokes the digital avatar sharing application module to obtain recommended digital avatars.
