Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0049] It should be noted that the terms "including" and "specific" in the present invention and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those clearly listed steps or units, but may include other steps or units that are not clearly listed or are inherent to these processes, methods, products, or devices.

[0050] Please refer to Figure 1 , Figure 1 It is a schematic diagram of the structure of an urban renewal project management platform provided by an embodiment of the present invention. The renewal management platform is built on a dual-engine architecture of Unreal and GIS. The urban renewal project management platform 10 includes:

[0051] A current situation data acquisition module 11, configured to acquire the current situation construction data of the urban renewal project at the current moment if it is detected that the urban renewal project has an update; wherein, the current situation construction data includes GIS data, oblique photography modeling data, and three-dimensional planning modeling data;

[0052] A three-dimensional model construction module 12, configured to construct a three-dimensional data model of the urban renewal project at the current moment based on the preset space management coding system according to the current situation construction data;

[0053] A construction project display module 13, configured to simulate and display the current situation real scene and planned virtual scene of the urban renewal project according to the three-dimensional data model;

[0054] The construction project tracking module 14 is used to save all three-dimensional data models of the urban renewal project and track the progress of the implementation of the urban renewal project according to all three-dimensional data models.

[0055] Exemplarily, in the dual-engine architecture of Unreal and GIS, efficient encoding conversion and formatting processing are performed on GIS data, and then a relational database is built for the Unreal Engine to call and parse. With the help of advanced query algorithms, accurate matching between the three-dimensional model and real data is achieved. At the same time, relying on the spatial management coding technology, the processing, aggregation, and replacement of geographical information data in the urban renewal process are completed, and then the dynamic data management and scene visualization presentation of the whole life cycle of urban renewal are realized.

[0056] For example, the three-dimensional oblique OSGB format data (oblique photogrammetry modeling data) of the urban renewal project obtained by low-altitude scanning of drones is used. After monomerization processing of each building in the urban renewal project, it is converted into 3DTILES format data; the planning and design model is processed to reduce the number of faces and lighten the weight, and the OBJ format data is exported; according to the orthophoto aerial images of drones, the top plane inspection of the three-dimensional planning and design model, and the optimization of the current situation and the GIS data of the foundation surface of the planned houses, the two-dimensional GIS data is made to coincide with the vector boundary of the bottom surface of the three-dimensional model, and after processing, the two-dimensional GIS foundation surface of the house and the ground data for regulatory planning are loaded. In the embodiment of the present invention, by connecting the urban platform and the drone scanning system, the whole-cycle control of the urban renewal project is realized, which can cover all stages such as the planning, design, construction, and operation of the project, realize the informatization and intelligent management of the whole process of the renewal construction project, and effectively improve the timeliness and feasibility of the platform in project management.

[0057] Specifically, the three-dimensional model construction module 12 includes:

[0058] Encoding conversion and formatting processing are performed on the current construction data by using a preset data conversion middleware to obtain the target current construction data recognizable by the Unreal Engine; wherein, the preset data conversion middleware is constructed based on the Unreal Engine and GIS technology;

[0059] According to a preset spatial management coding system, a spatial management code for the target current construction data is generated;

[0060] According to the target current construction data and the spatial management code, a three-dimensional data model of the urban renewal project at the current moment is constructed.

[0061] Exemplarily, after obtaining the target current construction data recognizable by the Unreal Engine through the preset data conversion middleware, in order to achieve a seamless link between the three-dimensional model and the two-dimensional GIS data, the data synchronization middleware is used to connect the three-dimensional data and the two-dimensional GIS data in the converted target current construction data, and then construct the three-dimensional data model of the urban renewal project at the current moment according to the connected target current construction data and the spatial management code. It is worth noting that the data synchronization middleware adopts an incremental update strategy and only transmits the changed data, which greatly reduces the amount of data transmission and improves the system response speed. Figure 2 As shown, Figure 2 A schematic diagram of the structure of a data synchronization middleware provided in an embodiment of the present invention is provided. The core of the data synchronization middleware includes a change detection layer, a data comparison layer, and a synchronous transmission layer. The target current construction data is input into the preset data synchronization middleware for data synchronization. The change detection layer quickly identifies the incremental changes of the three-dimensional model and the two-dimensional GIS data through the timestamp and version number mechanism; the data comparison layer uses the spatial hash algorithm to compare the data differences, and the R-tree index accurately locates the specific change content; the synchronous transmission layer adopts the compression channel and queue mechanism to ensure that only the changed data blocks are transmitted. The data synchronization middleware also has a built-in metadata management module to realize data version tracking and consistency verification, and supports data traceability and rapid recovery. The role of the data synchronization middleware in the embodiment of the present invention is to link the converted PostGIS data with the three-dimensional model data, and realize the function of querying and displaying GIS data by clicking on the three-dimensional model. For example, based on the constructed relational database (converted two-dimensional GIS data), with the help of advanced query algorithms, the accurate matching of three-dimensional data and two-dimensional GIS data and the opening of information links are realized, and each three-dimensional building model is associated with its corresponding two-dimensional building base surface data through the Web GIS system.

[0062] The embodiment of the present invention accesses the Web GIS system in the Unreal Engine through low-code development, and integrates the large-scale current scene in the geographic information system with the refined planning and design scene in the Unreal Engine, which not only quickly and efficiently realizes the integrated expression of the refined design model of the renewal construction project and the large-scale scene, but also improves the rendering accuracy and rendering effect of the virtual and real scenes, and can simulate the phased effect of urban renewal construction in a close to realistic way. By establishing a spatial management coding management system, the multi-modal and multi-temporal model data of the current situation and planning are managed in an integrated manner, and on this basis, the aggregation, processing, updating and rapid calling of urban renewal model information are realized, thereby improving the dynamic management efficiency of urban renewal projects.

[0063] More specifically, the preset data conversion middleware includes a data parsing module, a format conversion module, a space coordinate mapping module and a data compression module;

[0064] The data parsing module is used to identify and extract the spatial attributes and meta-information of the current construction data;

[0065] The format conversion module uses CUDA parallel computing technology to convert the current construction data structure into a data format recognizable by the Unreal Engine;

[0066] The spatial coordinate mapping module is used to perform coordinate conversion on different coordinates of the current construction data;

[0067] The data compression module reduces the volume of the current construction data by optimizing the data storage structure of the current construction data.

[0068] Exemplarily, an efficient conversion from GIS data to a data format recognizable by the Unreal Engine is achieved through self-developed data conversion middleware. As Figure 3 shown, Figure 3 FIG. is a schematic structural diagram of a data conversion middleware provided by an embodiment of the present invention. The data conversion middleware adopts a modular architecture and mainly includes four core components: a data parsing module, a format conversion module, a spatial coordinate mapping module, and a data compression module. The data parsing module is responsible for identifying and extracting the spatial attributes and meta-information of GIS data. For example, it performs processing such as format recognition, change detection, and attribute extraction on GIS data; the format conversion module uses CUDA parallel computing technology to convert the GIS data structure into a data format recognizable by the Unreal Engine; the spatial coordinate mapping module ensures accurate conversion between different coordinate systems; the data compression module reduces the data volume by optimizing the data storage structure. The entire middleware is based on a plug-in design and can flexibly adapt to the needs of different types of GIS data sources and rendering engines. The middleware adopts CUDA-accelerated multi-threaded parallel processing technology and utilizes the parallel computing power of the GPU to increase the GIS data conversion speed by approximately 300%. The converted data is stored in a specially designed PostGIS spatial relational database, which adopts an R-tree index structure and cooperates with the GiST (Generalized Search Tree) index framework to improve the retrieval efficiency of spatial data by approximately 500% and reduce the query response time to the millisecond level.

[0069] Specifically, the construction project display module 13 includes:

[0070] Define the rendering duration of the three-dimensional data model according to the spatial management code of the three-dimensional data model;

[0071] Simulate and display the current actual scene and the planned virtual scene of the urban renewal project through the rendering duration.

[0072] Exemplarily, platform users can interact with 3D models intuitively through user-friendly interaction designs. After clicking on a 3D model, the system instantaneously retrieves relevant information from the database using an advanced query algorithm, including multi-dimensional GIS data such as building height, building function, building area, and population using the building, to achieve precise data display and query. For example, an advanced query algorithm based on a hybrid index of spatial hashing and R-tree is adopted. This algorithm first quickly locates the target area through spatial hashing and then uses the R-tree for precise matching, significantly improving the query efficiency.

[0073] Furthermore, the construction project display module 13 further includes:

[0074] Select the target 3D data model within the target range and summarize and calculate the building data of the target 3D data model; determine the target rendering duration of the target 3D data model according to the building data;

[0075] Load the corresponding 3D data model in the order of the spatial management code to display the update process of the urban renewal project.

[0076] Exemplarily, according to the order of "data update year, month, and day" in the spatial management code, customize the model rendering duration for each stage, load and render the corresponding 3D oblique photography model one by one, dynamically play the urban renewal process, and automatically record the screen to generate a multimedia video in MP4 format. Click and select or box-select any 3D building models within a range, automatically summarize and calculate the building height, building function, building area, and population data included; retrieve any regulatory planning land code or spatial management code, and replace the 3D oblique photography model with a planning and design model; select any perspective in the platform as a key frame and set the rendering duration between each key frame. The platform screen camera will move and render the planning and design model uniformly according to the key frame order and time parameters, and the platform will automatically record the screen and export a multimedia video in MP4 format.

[0077] Specifically, the construction project tracking module 14 includes:

[0078] Save all 3D data models of the urban renewal project according to the spatial management code of the 3D data model;

[0079] Obtain the 3D data model at the current moment according to the spatial management code;

[0080] Determine the update stage of the urban renewal project according to the 3D data model at the current moment to track the implementation progress of the urban renewal project.

[0081] Exemplarily, a real-time ray tracing global illumination technology based on NVIDIA RTX technology is adopted, combined with the Nanite and Lumen systems of the Unreal Engine. The Nanite system supports per-pixel triangle (PPTT) technology, which can render scenes with more than one billion polygons at 4K resolution while maintaining a refresh rate of 60+ FPS. The Lumen system realizes dynamic global illumination, supports real-time reflection, refraction, and indirect illumination calculations, can accurately simulate the lighting effects under different times and weather conditions, and the rendering accuracy is increased by about 500%.

[0082] According to the planned land use code input in the renovation implementation plan, the platform relies on the spatial management coding technology to automatically locate the relevant current situation scene models and replace them with the latest three-dimensional planning and design model solutions. During the user interaction process, the system realizes the intuitive presentation of the planning update effect by intelligently judging and rendering the dynamic conversion of the old and new three-dimensional models in real time. At the same time, the system intelligently statistics and displays the comprehensive information summary of the planned demolished buildings and the planned newly built buildings, supporting the dynamic monitoring and visual analysis of the entire life cycle of the project.

[0083] Exemplarily, according to the spatial management coding and the corresponding vector range line, based on the regular scanning of the urban environment by drones, models at different update stages are output; through the top plane of the RNN machine learning model, the building base plane positions and areas of the original current situation models are compared to identify the demolition progress, and the judgment logic is as follows:

[0084] Assume that the serial number of the original building model is i ∈ [1, N], then the building area of the i-th original building is Si, and the serial number of the updated building model obtained by the x-th scan is j ∈ [1, M], then the building area of the j-th updated building is Sj.

[0085] By comparing the top planes of the original building model and the updated building model through the RNN model, it is identified that there are t building models with consistent positions and building areas (the geometric center position coordinates error < 1 meter and the building area error < 10 ㎡ are regarded as consistent).

[0086] If t = i = j, then the latest building base plane coincides with the current situation model, and the "update stage" is "not demolished", and the corresponding field of the spatial management coding is recorded as 01;

[0087] If t = j and < i, then some of the current situation buildings have been demolished, and the "update stage" is "under demolition", and the corresponding field of the spatial management coding is recorded as 02;

[0088] If t = 0 and j = 0, then the current situation has been demolished flat, and the "update stage" is "demolished and not implemented", and the corresponding field of the spatial management coding is recorded as 03;

[0089] If t = 0 and j > 0, the current situation starts to build a new building, and the "update stage" is "under construction", and the corresponding field of the spatial management code is recorded as 04;

[0090] Refer to the original model code and the update stage recognition result, automatically generate the spatial management codes for the 3D building model and the 2D building base surface, and enter them into the update database to update the 3D data model.

[0091] More specifically, constructing the 3D data model of the urban renewal project at the current moment according to the target current situation construction data and the spatial management code includes:

[0092] Publish the target current situation construction data to the Unreal Engine through low-code development, and perform spatial correction on the target current situation construction data;

[0093] Unify the projection coordinate system and elevation datum of the tilt photography modeling data, 3D planning modeling data and GIS data in the corrected target current situation construction data to obtain the 3D data model of the urban renewal project at the current moment.

[0094] Exemplarily, through low-code development, publish the large-scale current situation tilt photography data to the Unreal Engine, synchronously load the 3D planning design model, 2D current situation and planning house base surface GIS data, and perform spatial correction with the vector range line of the urban renewal unit as a reference. Unify the 3D model and 2D GIS into the CGS2000 plane projection coordinate system and elevation datum to obtain the 3D data model of the urban renewal project at the current moment.

[0095] More specifically, generating the spatial management code for the target current situation construction data according to the preset spatial management code system includes:

[0096] Assign values to the target current situation construction data according to the preset spatial management code system to obtain the corresponding building data group;

[0097] Generate the spatial management code for the target current situation construction data according to the building data group.

[0098] Exemplarily, a spatial management coding system is established according to the coding rule of "planned land number - current / planned building type - building sorting - data update date - update stage" to assign values to the 3D model and GIS data: generate the geometric center points of the regulatory planning land and the building base surface, select the current and planned building data corresponding to the regulatory planning land according to the intersection situation. If the building intersects with multiple plots or does not intersect with any plot, it is included in the adjacent regulatory planning land according to the geometric center distance to form a building data group corresponding to each regulatory planning land; in the order from top to bottom and from left to right, the original code is automatically generated for the building data group in the form of "planned land number - current / planned building type - building sorting - data update date - update stage" (for example, AY010103-01-01-20240708-01).
