[0041] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0042] In one embodiment, Figure 1 As shown, a digital twin scene editor is provided, which includes: a data integration layer, a model editing layer, a human-computer interaction layer, and a comprehensive service layer.

[0043] The data integration layer is used to obtain external data and pass it to the model editing layer and the human-computer interaction layer for updating the digital twin model parameters and chart data; the model editing layer is used to edit the digital twin model and associate external data with the digital twin model parameters; the human-computer interaction layer is used to process the interaction process between the user and the digital twin model; the comprehensive service layer is used to optimize the performance of the entire digital twin scene editor.

[0044] The digital twin scene editor is built on a low-code development platform, primarily the Unity 3D virtualization platform. Its primary function is to provide the building tools and runtime environment for the digital twin scene editor, greatly simplifying the creation of digital twin models and lowering the development threshold. This platform allows for low-code editing and configuration of event interactions within the digital twin system, significantly simplifying interaction design and improving system usability.

[0045] Among them, the data integration layer serves as the basis of the digital twin scene editor. Its main function is to integrate external data into the digital twin scene editor according to the needs of digital twin model editing.

[0046] Among them, the model editing layer, as the core of the digital twin scene editor, mainly refers to a series of edits to the digital twin model. It is also the service object of external data in the data integration layer.

[0047] Among them, the human-computer interaction layer is an important part of the digital twin scene editor, which is mainly responsible for processing the interaction process between users and digital twin models.

[0048] The integrated service layer, whose primary function is to optimize the performance of the entire digital twin scene editor, consists of a caching mechanism and a Levels of Detail (LOD) module. The caching mechanism accelerates the operation of the entire digital twin scene editor by caching frequently used digital twin models and data. The LOD module automatically switches between different levels of detail based on the display distance of the digital twin model, reducing computational complexity.

[0049] Among them, the LOD module uses LOD technology to automatically switch between different levels of detail according to the display distance of the digital twin model.

[0050] The aforementioned digital twin scene editor includes: a data integration layer, a model editing layer, a human-computer interaction layer, and an integrated service layer. The data integration layer is used to obtain external data and pass it to the model editing layer and the human-computer interaction layer for updating digital twin model parameters and chart data. The model editing layer is used to edit the digital twin model and associate external data with the digital twin model parameters. The human-computer interaction layer is used to handle the interaction process between the user and the digital twin model. The integrated service layer is used to optimize the performance of the entire digital twin scene editor. Therefore, through this multi-level design, the digital twin scene editor not only achieves comprehensive functional coverage, but also ensures the flexibility and ease of use of the system, allowing even non-professional developers to quickly get started and create high-quality digital twin models, improving work efficiency.

[0051] In one embodiment, the data integration layer includes a sensor data interface and an API integration module; the sensor data interface obtains external data in real time by connecting to external sensors; the API integration module provides an API interface for accessing third-party services or databases to obtain more types of external data.

[0052] Among them, the sensor data interface mainly connects to external sensors to obtain external data in real time and applies it to the digital twin model, thereby realizing dynamic updating of the digital twin model.

[0053] Among them, the API integration module facilitates users to access third-party services or databases by providing API interfaces, thereby obtaining more types of external data.

[0054] In one embodiment, the model editing layer includes a visual modeling module, a parametric modeling module, a material texture editing module and a data processing module; the visual modeling module is used to allow users to create and modify digital twin models in an intuitive manner; the parametric modeling module is used to provide a parametric modeling method, adjusting a series of set parameters to customize and modify the digital twin model; the material texture editing module is used to adjust the appearance characteristics of the surface of the digital twin model to make the digital twin model closer to the real-world model; the data processing module is used to automatically match external data to the corresponding module of the model editing layer according to type, to ensure the association between external data and digital twin model parameters.

[0055] The visual modeling module is an important component for editing digital twin models and realizing their visualization. The visual modeling module can be composed of two parts: a drag-and-drop interface and a model library. In the drag-and-drop interface, users can add and arrange basic geometric bodies (such as cubes, spheres, and cylinders) by simply dragging and dropping, and adjust their position, size, and rotation angle. In the model library, there are pre-reserved digital twin models of various geometric shapes and complex objects. Users can directly choose to reuse the digital twin model or make slight modifications.

[0056] Among them, the parametric modeling module mainly customizes and modifies the digital twin model by adjusting a series of set parameters. The parametric modeling module can include a property panel and a formula support unit. Among them, the property panel is equipped with each digital twin model, and has parameters such as the digital twin model's spatial information, asset information, joint parameter color information, and material type. Its main function is to edit the digital twin model by directly adjusting the parameters, thereby realizing low-code development. In the formula support section, various behavioral rules are reserved in advance by building classes. Users can dynamically generate digital twin model parameters by entering simple mathematical formulas.

[0057] The material texture editing module adjusts the surface appearance of the digital twin model, such as diffuse color, ambient occlusion, metallicity, and smoothness, to make the digital twin model closer to the real-world model. The material texture editing module can include a material library, a texture map import unit, and a PBR material editing unit.

[0058] The data integration layer distributes external data (such as real-time sensor data and API structured data) to the functional modules of the model editing layer through a unified data bus, forming a closed-loop "collection-analysis-application" chain. The digital twin scene editor in this application establishes a data semantic labeling system, automatically matching external data by type (such as environmental data, device status data, and spatial coordinate data) to the corresponding modules in the model editing layer, ensuring a precise association between data and digital twin model parameters.

[0059] In one example, in the parametric modeling module, external data (such as temperature sensor readings and equipment load rates) are converted into digital twin model geometric parameters (such as dimensions and deformation coefficients) and physical properties (such as material strength and thermal conductivity) using a predefined parameter mapping rule library. In the formula support unit, external data is used as input variables in parameter calculations (for example, model stress = sensor pressure value × safety factor), enabling data-driven dynamic reconstruction of the digital twin model.

[0060] In one example, in the visual modeling module, real-time external data (such as equipment vibration frequency and energy consumption) is bound to the digital twin model's visual status tagging system, dynamically displaying data changes through color gradients and particle effects. GPS / indoor positioning data obtained through an API drives the digital twin model's spatial position update in the 3D field, achieving positional mapping between physical entities and the digital twin model.

[0061] In one example, in the material texture editing module, external data such as external lighting, temperature and humidity are input into the PBR material calculation engine to dynamically adjust parameters such as the metallicity and roughness of the surface of the digital twin model (such as enhancing the metal oxidation effect in a high temperature environment).

[0062] Before data is injected into the digital twin model, pre-set data validation rules (range thresholds, logical conflict detection) filter out anomalous data to prevent model distortion caused by incorrect parameters. After the digital twin model parameters are updated, a change log is automatically generated and transmitted back to the data integration layer, triggering external device control instructions (such as adjusting real-world device operating parameters through APIs), forming a closed "perception-modeling-control" loop.

[0063] In one embodiment, the visual modeling module includes a drag-and-drop interface and a model library; in the drag-and-drop interface, the user adds and arranges basic geometric bodies by simply dragging and dropping, and adjusts the position, size, and rotation angle of the basic geometric bodies to create and modify the digital twin model; in the model library, there are a variety of geometric shapes and complex object digital twin models reserved in advance, and the user can directly choose to reuse the user's digital twin model or modify it based on the existing digital twin model as needed.

[0079] In one embodiment, the integrated service layer includes a caching mechanism and an LOD module. The caching mechanism is used to cache frequently used digital twin models and data. The LOD module automatically switches to different levels of detail according to the display distance of the digital twin model.

[0081] The above-mentioned digital twin scene editor combines a graphical interface and a small amount of code, which greatly simplifies the operation process, allowing many non-professionals to participate in digital twin projects, greatly improving work efficiency.

[0082] In one embodiment, Figure 2 As shown in the figure, the digital twin scene editor is completed based on the low-code development platform (Unity3D virtual platform). The data integration layer serves as the foundation of the digital twin scene editor. The sensor data interface allows real-time collection of various data in the physical world, such as temperature, humidity, location, etc. These data can be directly fed back into the digital twin model, enabling the digital twin model to reflect real environmental changes. The API integration module provides access to third-party data sources, such as weather forecasts and traffic flow, which can be used to simulate the behavior of the digital twin model under specific conditions. In summary, the data obtained from the external data integration layer can be passed to the model editing layer and the human-computer interaction layer for updating model parameters and chart data, thereby enhancing the authenticity and real-time performance of the digital twin model and charts.

[0083] like Figure 2 As shown in the figure, the model editing layer, as the core of the digital twin scene editor, is primarily responsible for editing the digital twin model. The visual modeling module allows users to create and modify digital twin models in an intuitive manner (drag and drop, rotate, scale, and so on for 3D objects). The parametric modeling module provides a parametric modeling approach, allowing users to change the shape and size of the digital twin model by adjusting parameters. The material and texture editing module allows users to customize the surface materials and textures of the digital twin model to enhance the realism and visual effects of the digital twin model. In summary, this model editing layer receives data from the data integration layer to dynamically adjust model parameters and ensure that the digital twin model reflects the latest environmental status. At the same time, the data and model structure generated by this layer can be used by the integrated service layer for performance optimization. The digital twin model created by this layer can be used as material by the human-computer interaction layer to provide users with a rich interactive experience.

[0084] like Figure 2As shown, the human-computer interaction layer is a crucial component of the digital twin scenario editor, primarily responsible for handling user interaction with the digital twin model. The process animation editing module allows users to define animated representations of the digital twin model during different process flows, such as the movements of a robotic arm on a production line, thereby helping users better understand the process flow. The interaction design module provides user interface elements, allowing users to interact with the digital twin model through clicks, dragging, and other methods. The chart management module displays key indicators and data during the digital twin model's operation, helping users understand the model's behavior and status. In summary, this layer receives data from the data integration layer to dynamically update the interactive interface and charts, ensuring timely information. Furthermore, the integrated service layer provides performance optimization technologies for its operation, ensuring smooth and seamless interaction.

[0085] like Figure 2 As shown in Figure 1, the main function of the integrated service layer is to optimize the performance of the entire digital twin scene editor. The caching mechanism caches frequently accessed data and resources, reducing repeated loading and improving system responsiveness. The LOD module automatically adjusts the model's level of detail based on the distance between the observer and the model, saving computing resources and improving rendering efficiency. Overall, the caching mechanism reduces data transmission between the data integration layer and the model editing layer, reducing latency. The LOD module directly influences the rendering quality of the human-computer interaction layer, ensuring a good user experience under different hardware conditions.

[0086] The aforementioned digital twin scene editor uses a low-code development platform (Unity 3D virtual platform) as the foundation for the development of the entire digital twin scene editor. By providing a development environment that integrates all of the aforementioned functions, it enables the rapid construction of digital twin models and scenes. By providing a rich set of built-in animation editing tools and interactive design components, it simplifies the implementation process of complex functions. By providing an efficient rendering engine, it presents high-quality three-dimensional graphics. In short, all data integration, model editing, human-computer interaction, and performance optimization functions are implemented on this platform. Through the scripting language provided by Unity, developers can implement low-code development of the digital twin scene editor. Through this multi-level design, the digital twin scene editor not only achieves comprehensive functional coverage, but also ensures the system's flexibility and ease of use, allowing even non-professional developers to quickly get started and create high-quality digital twin models.
