Description

Technical Field

[0001] The present invention relates to the field of three-dimensional model display, and specifically relates to a three-dimensional model display interaction method and system based on a multi-dimensional variable expression. Background Art

[0002] With the development of information technology, in the field of BI analysis large screen / cockpit display, more three-dimensional graphics and animations are used to intuitively present complex data relationships, trends, and patterns, helping users better understand the data. However, the application of three-dimensional models is not only integrated with the display of data itself, but also needs to be integrated and linked with other data sources in the business display scenario to achieve comprehensive analysis and dynamic visualization display of data.

[0003] When implementing these business scenarios, it is often necessary for developers to carry out custom development. First, based on the data, logical processing is performed to form data that meets the display requirements. Then, relying on a third-party open-source framework, a three-dimensional data model is displayed, and relevant event listening and processing logics are registered. When the model attributes change, corresponding linkage processing is triggered according to the custom logic; at the same time, event listening and processing logics are registered for the graphic display objects of other data in the page. When the user operates, corresponding changes in the three-dimensional model attributes are triggered according to the custom logic, such as the selected three-dimensional object, camera perspective, triggering three-dimensional animation effects, etc.; through this custom coding, support for complex three-dimensional model display interaction business scenarios is achieved.

[0004] In this mode, first, it has high requirements for the technical capabilities of developers, and in-depth understanding of technologies such as three-dimensional display is required; second, the demand response speed of custom coding is very poor. From the time the demand is proposed to the implementation and deployment in the production environment, it often takes several weeks. When the display requirements change, the above R & D process needs to be repeated, and the demand iteration cannot be quickly responded to.

[0005] The disadvantages of the three-dimensional model rendering and display effects implemented by the prior art also include: The loading of three-dimensional models and their display styles in the page are usually fixed, such as colors, sizes, etc., and cannot change synchronously with external information.

[0038] Based on the patent with the authorization number CN114428823B and the name "Data linkage method, device, equipment and medium based on multi-dimensional variable expression", the present invention utilizes its multi-dimensional variable expression technology to design a flexible configuration three-dimensional model data display and interaction technology and device, which can realize the online configuration ability of three-dimensional model data display and interaction linkage with other chart components on the large screen / cockpit interface without customized coding development, can greatly improve the implementation speed of similar business scenarios, reduce technical requirements, and realize the rapid response to user requirements.

[0039] To better understand the present invention, the content of the present invention will be further described below in conjunction with the specification drawings and embodiments.

[0040] Embodiment 1:

[0041] A three-dimensional model display and interaction method based on a multi-dimensional variable expression, as Figure 1 shown, includes:

[0042] Step 1: A data set queries the storage address of the three-dimensional model required for the current business scenario from the backend according to the data set query condition, wherein the data set query condition is bound to a context variable;

[0043] Step 2: When the storage address queried by the dataset changes, trigger the reload and display of the 3D model display interaction component bound to the dataset.

[0044] The following further introduces each step:

[0045] Step 1: The dataset queries the storage address of the 3D model required for the current business scenario from the backend according to the dataset query conditions. Among them, the dataset query conditions are bound to context variables, including:

[0046] When the data query conditions change, trigger the dataset to re-query the storage address of the 3D model required for the current business scenario from the backend.

[0047] The specific steps of Step 1 are as follows:

[0048] 1) In the present invention, first, a 3D model loading and display technology based on the dataset is constructed. Among them, the dataset is responsible for querying the storage address of the 3D model required for the current business scenario from the backend. The query conditions can depend on context variables. When the context variables change, trigger the dataset to re-query the data. Among them, the 3D model display interaction component is responsible for the loading and display of the 3D model. The component binds to the 3D model storage address column of the dataset. When the address data changes, trigger the 3D model to be reloaded and displayed. The 3D display controller of the 3D model display interaction component realizes the binding of attributes such as camera coordinates and viewing angles to context variables through multi-dimensional variable expressions. When the context variables change, it will automatically trigger the change of camera attributes, and the refresh of the 3D model display effect is realized through the controller.

[0049] Before Step 2, it also includes:

[0050] 2) In the 3D model display interaction component of the present invention, when it is created on the cockpit page, it will listen for mouse events. When the mouse clicks on an object in the 3D model, according to the configured multi-dimensional variable expression, the business data information associated with the clicked object is calculated and then updated to the global context variable set.

[0051] Step 2: When the storage address queried by the dataset changes, trigger the reload and display of the 3D model display interaction component bound to the dataset, including:

[0052] The 3D display controller of the 3D model display interaction component binds the attributes to context variables through multi-dimensional variable expressions. When the context variables change, trigger the change of attributes and refresh the 3D model display effect;

[0053] Among them, the attributes include: camera coordinates, viewing angle.

[0054] The specific implementation steps of Step 2 are as Figure 2 shown:

[0055] 3) In the data sets on the current cockpit page (including the data sets associated with various charts and the data set of the storage path of the 3D model), the data query condition can be a multi-dimensional variable expression containing context variables. At this time, it will be bound to the context variables. When the value of the bound context variable changes due to 2), it will trigger the recalculation of the multi-dimensional variable expression and trigger the re-query of the data set. The data change of the data set will, in turn, trigger the reloading and rendering of its associated chart or 3D model.

[0056] The display styles (such as colors, line types, fonts, etc.) of the charts on the current cockpit page can be bound to context variables through multi-dimensional variable expressions. When the value of the bound context variable changes due to 2), it will trigger the recalculation of the multi-dimensional variable expression and trigger the refresh of the display effect of the chart.

[0057] By introducing the multi-dimensional variable expression technology, the present invention can define the two-way binding relationship between data and 3D models and between 3D models and context variables through page configuration for the original customized service linkage logic that needed to be implemented by coding. Through the expression execution engine, the automatic triggering and execution of the configured two-way binding relationship can be realized. In this way, the online configuration and construction of the 3D model display scenario can be achieved without coding development and the participation of R & D personnel, and it can flexibly and agilely respond to user requirements.

[0058] In the large-screen display scenario, the demand for displaying 3D models and interacting with users is becoming more and more common. The conventional implementation solutions generally adopt the customized development method to achieve specific map rendering effects for specific 3D models; in addition, in some BI tools, the function of loading and rendering customized 3D models is also encapsulated, but the ability to dynamically switch models or interactively configure the 3D objects inside the model with other chart items on the large screen is poor. Generally, it lacks flexibility and is difficult to achieve on-demand configuration and dynamic change.

[0059] Based on the flexible binding and triggering mechanism of multi-dimensional variable expressions, the present invention realizes the dynamic loading of 3D models and the flexible and configurable two-way dynamic linkage effect between the internal objects of the models and the large-screen / cockpit charts.

[0060] A 3D model interactive display technology and device based on multi-dimensional variable expressions, including a 3D model dynamic loading and display based on a data set, a dynamic interaction model between a 3D model controller and context variables, and an interactive model of two-way linkage between 3D model graphic objects and context variables / other charts.

[0061] (1) The 3D model display interaction component that realizes 3D display control and 3D model loading and display based on multi-dimensional variable expression technology;

[0062] (2) The interaction model between the 3D model display controller and the context variables based on the multi-dimensional variable expression technology;

[0063] (3) The interaction model between the 3D model graphic object and the context variables based on the multi-dimensional variable expression technology;

[0064] (4) The interaction model between the 3D model graphic object and other charts based on the multi-dimensional variable expression technology.

[0065] Compared with the prior art, the advantages of the present invention are as follows: Through the multi-dimensional variable expression, the dynamic binding of the linkage relationship among business data, context variables, 3D model display effects, and interactive control can be realized, so as to support the flexible dynamic linkage based on the multi-dimensional variable expression between the 3D model display and business data and context variables in analysis and display scenarios such as cockpits and large screens, without the need for custom development (coding), and only configuration is required.

[0066] Embodiment 2

[0067] The present invention based on the same inventive concept also provides a 3D model display interaction system based on the multi-dimensional variable expression, including:

[0068] An address query module, configured to query the storage address of the 3D model required for the current business scenario from the backend according to the dataset query condition for the dataset, wherein the dataset query condition is bound to the context variable;

[0069] A display module, configured to trigger the reloading and display of the 3D model display interaction component bound to the dataset when the storage address queried by the dataset changes.

[0070] Optionally, the display module is specifically configured to:

[0071] The 3D display controller of the 3D model display interaction component binds the attributes to the context variables through the multi-dimensional variable expression. When the context variable changes, it triggers the change of the attributes and refreshes the 3D model display effect;

[0072] Wherein, the attributes include: camera coordinates, viewing angle.

[0073] Optionally, it further includes a variable update module, configured to: when creating a 3D model display interaction component on the page, listen for mouse events and update the context variable set.

[0074] Optionally, the variable update module is specifically configured to: when the mouse clicks on an object in the 3D model, calculate the business data information associated with the clicked object according to the configured multi-dimensional variable expression, and update it to the global context variable set.

[0075] Optionally, the data set includes data sets associated with various types of charts and data sets of three-dimensional model storage paths.

[0076] Optionally, the address query module is specifically configured to:

[0077] When the data query condition changes, trigger the data set to query the storage address of the three-dimensional model required for the current business scenario from the backend again.

[0078] Embodiment 3

[0079] Step 1: The data set queries the storage address of the three-dimensional model required for the current business scenario from the backend according to the data set query condition, where the data set query condition is bound to the context variable, and the specific implementation method is as follows:

[0080] Determine the required three-dimensional model type and characteristic attributes according to the business scenario to form a data set query condition;

[0081] Bind the data set query condition to the context variable to ensure that the query condition can dynamically adapt to the requirements of different business scenarios;

[0082] In the backend database, retrieve the matching three-dimensional model records according to the data set query condition to obtain the model information that meets the conditions;

[0083] Filter and sort the retrieved three-dimensional model records, and preferentially select the model with the highest relevance to the current business scenario.

[0084] Extract the storage address information from the three-dimensional model record and verify the address format and validity.

[0085] Associate the obtained three-dimensional model storage address with the corresponding model attribute information to form complete model acquisition result data.

[0086] Return the model acquisition result data to the front end for use when the business scenario renders and displays the three-dimensional model.

[0087] Determine the required three-dimensional model type and characteristic attributes according to the business scenario to form a data set query condition.

[0088] For example, in the smart city management scenario, it is necessary to obtain three-dimensional models of urban infrastructure such as buildings, roads, and greenery, and at the same time, the models need to include attribute information such as name, type, size, and coordinate position.

[0089] The system dynamically generates a database query statement by binding these conditions to context variables (such as the current city, region, time, etc.).

[0090] The backend database retrieves the matching 3D model records according to the query statement, and uses algorithms such as inverted index and Boolean model to quickly obtain the model information that meets the conditions.

[0091] Then, the retrieval results are filtered and sorted. Considering factors such as the relevance, integrity, and update time of the models, the weighted average algorithm is used to calculate the comprehensive score of each model, and the model with the highest score is preferentially selected.

[0092] Next, the storage address information in the model record is extracted, and the address format is verified through regular expressions to ensure that the address conforms to the URL specification.

[0093] Finally, the model address is associated with the model attribute information, and the result data in JSON format is generated and returned to the front end.

[0094] According to the business scenario requirements, the front end selects a suitable 3D rendering engine and technical framework, loads and displays the obtained model data, and realizes the visualization and interactive operation of the 3D scene.

[0095] Through this series of processes, a complete link from the business scenario to the acquisition and display of 3D models is realized, improving the management and application efficiency of 3D data.

[0096] Step 2: When the storage address queried by the dataset changes, trigger the 3D model display interaction component bound to the dataset to reload and display. The specific implementation steps are as follows:

[0097] Obtain the storage address queried by the dataset, and determine whether the address has changed. If it has changed, trigger the reloading of the 3D model display interaction component associated with the dataset;

[0098] Obtain the 3D display controller of the 3D model display interaction component, and bind attributes such as camera coordinates and viewing angles to context variables through multi-dimensional variable expressions;

[0099] Monitor the changes of context variables. If changes are detected, trigger the changes of attributes such as camera coordinates and viewing angles, and pass the changed attribute values to the 3D display controller;

[0100] The 3D display controller adjusts the display effect of the 3D model according to the received changed values of attributes such as camera coordinates and viewing angles, and realizes the refresh of the 3D model display.

[0101] Adopt the support vector machine algorithm to train the historical display effect data of the 3D model to obtain the optimal combination of camera coordinates and viewing angle parameters for subsequent optimization of the 3D model display effect.

[0102] Analyze the user's interaction behavior data through a clustering algorithm to obtain the interaction preferences of different user groups, and dynamically adjust the display effect of the 3D model according to the interaction preferences to provide personalized 3D model display services.

[0103] Construct an evaluation model for the display effect of the 3D model, use the decision tree algorithm to evaluate the display effect of the 3D model, and dynamically optimize attributes such as camera coordinates and viewing angles according to the evaluation results to continuously improve the quality of 3D model display and user experience.

[0104] First, the system will obtain the storage address of the dataset query. For example, by accessing the metadata table in the database, the storage path of the dataset is obtained as " / data / dataset / model_data".

[0105] Then, the system will compare the currently obtained storage address with the previously stored address. If it is found that the address has changed, it will trigger the reloading of the 3D model display interaction component associated with the dataset.

[0106] Next, the system will obtain the 3D display controller of the 3D model display interaction component, and bind attributes such as camera coordinates (x, y, z) and viewing angles (yaw, pitch, roll) to context variables (such as user ID, timestamp, etc.) through multi-dimensional variable expressions.

[0107] The system will monitor the changes of context variables in real time. For example, if user A accesses the system at 10:30:00 on May 20, 2023, the generated context variables will be {userID: "A", timestamp: "2023-05-20 10:30:00"}. Once it is detected that the context variables have changed, it will trigger changes in attributes such as camera coordinates and viewing angles, and pass the changed attribute values, such as (15, 28, 12) and (45°, 60°, 30°), to the 3D display controller.

[0108] The 3D display controller adjusts the vertex coordinates and rendering parameters of the 3D model through algorithms such as matrix transformation according to the received changed values of attributes such as camera coordinates and viewing angles to achieve the refresh of 3D model display.

[0109] At the same time, the system will also use the support vector machine (SVM) algorithm to train the historical display effect data of the 3D model.

[0110] By selecting the Gaussian kernel function, setting the penalty coefficient C = 0, and training 10,000 sample data, the optimal combination of camera coordinates (13, 17, 6) and viewing angle parameters (60°, 45°, 25°) is obtained for subsequent optimization of the 3D model display effect.

[0111] In addition, the system will also analyze the interaction behavior data (such as the number of clicks, access duration, etc.) of 5000 users through the K-means clustering algorithm, divide the users into 3 groups, and respectively obtain the interaction preferences of each group (such as group A prefers the top-down angle, group B prefers the horizontal perspective, etc.). According to the interaction preferences, the display effect of the 3D model is dynamically adjusted to provide a personalized 3D model display service.

[0112] Finally, the system will also construct an evaluation model for the display effect of the 3D model, adopt the CART decision tree algorithm, and generate a decision tree model by analyzing the characteristics (such as frame rate, loading time, etc.) of 1000 3D model display effect samples and user ratings.

[0113] The display effect of the new 3D model is evaluated according to the decision tree model, and the score of the display effect is obtained as 2 points (full score 5 points). According to the evaluation results, the attributes such as the camera coordinates and perspective are dynamically optimized, such as adjusting the camera coordinates to (18, 12, 11) and the perspective to (55°, 50°, 20°), so as to continuously improve the quality of 3D model display and user experience.
