Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0024] The following is combined with Figures 1-5 This invention describes the building renovation and expansion method, apparatus, and electronic equipment provided in embodiments of the present invention.

[0025] Figure 1 This is one of the flowcharts illustrating the building renovation and expansion method provided by the present invention, such as... Figure 1 As shown, the method for renovating and expanding a building includes steps S100 to S300, and the specific steps are as follows:

[0026] S100: Combine the spatial data of the building with the GIS system to obtain the building's GIS data system.

[0027] Spatial data includes above-ground space data and underground space data of buildings.

[0028] It should be noted that the execution subject of the embodiments of the present invention can be a server, computer equipment, such as a mobile phone, tablet computer, laptop computer, handheld computer, vehicle electronic equipment, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), etc.

[0029] The buildings covered by this invention include airports, railway stations, subway stations, and other buildings that require renovation or expansion.

[0030] A GIS system is a software system or platform that combines functions such as geographic data collection, storage, management, analysis, and display. It is used to process and manage geographic location-related data and perform operations such as spatial analysis, spatial decision support, and map creation.

[0031] The process involves acquiring spatial data, specifically: obtaining above-ground structural information of the building based on 3D scanning information; obtaining environmental information of the building within a defined area based on oblique photography information, including geographical information, traffic route information, and ground construction progress information; scanning underground pipes and / or cables of the building to obtain underground space information; and obtaining spatial data based on above-ground structural information, environmental information, and underground space information.

[0032] High-precision spatial data, including information on buildings, terrain, landforms, and underground pipelines, is obtained by integrating 3D scanning technology with a GIS system. Light Detection and Ranging (LiDAR) is used to perform high-precision 3D scanning of the building's ground and terrain, acquiring the building's external outline, facade information, and ground elevation data.

[0033] Based on the 3D scan information of the building, the above-ground structural information of the building is obtained. Specifically, the 3D scan information of the building's external structure and the 3D scan information of its internal structure are stitched together to obtain the above-ground structural information.

[0034] like Figure 2 As shown, a 3D scan of the building's internal structure is performed to obtain its 3D scanning information. A 3D scan of the building's external structure is also performed to obtain its 3D scanning information. The 3D scanning information of the internal and external structures is then automatically stitched together to obtain the building's complete above-ground structural information. Furthermore, the above-ground structural information and underground space information are then automatically stitched together to obtain the building's complete structural information.

[0035] Oblique photography is performed on the building to obtain environmental information about its surroundings, such as geographic information within 5km (obtaining surrounding geographic information), traffic routes, and ground construction progress. Furthermore, the environmental information obtained from the oblique photography is verified against the building's Building Information Modeling (BIM) model.

[0036] Using underground surveying technologies such as Ground Penetrating Radar (GPR), three-dimensional scanning is performed on underground pipes and cables within buildings to obtain information on their location, depth, and type, thus acquiring information about the underground space. Furthermore, the underground pipes, cables, and geology of buildings are surveyed to obtain data on underground obstacles and geological structures, thereby refining the information on the underground space.

[0037] Spatial data includes above-ground structural information, environmental information, and underground structural information. By utilizing a GIS system, various types of spatial data are interactively integrated to obtain the building's GIS data system.

[0038] like Figure 3The building GIS data system includes a data acquisition module, a data processing module, a data storage and management module, a visualization module, and a renovation and expansion scheme determination module. The data acquisition module acquires above-ground structural information, environmental information, and underground space information. The data processing module processes and stitches together the above-ground and underground space data. The data storage and management module stores and manages the above-ground and underground space data. The visualization module displays the building model and the renovation or expansion process. The renovation and expansion scheme determination module performs project planning and design, risk assessment, environmental impact assessment, visualization of renovation and expansion schemes, resource optimization, and resource sharing for the building's renovation and expansion process.

[0039] S200: Based on the building GIS data system, determine the parameters for the renovation and expansion of buildings.

[0040] The parameters for renovation and expansion should include at least the building's optimal access route, construction restriction areas, the difficulty of renovation or expansion, risk information, and environmental impact information.

[0041] Based on a building GIS data system, parameters for building renovation and expansion are determined. Utilizing functions such as buffer analysis, network analysis, and path analysis within the building GIS data system, the optimal location for renovation or expansion, as well as the building's road layout, are determined. For example, buffer analysis identifies construction restriction zones within a preset area, and path analysis determines the optimal traffic routes. Visualization and spatial query tools within the building GIS data system are used to analyze and mine the building's geographic data, aiding in determining the optimal facility arrangement. For example, spatial queries determine the relationship between underground pipelines and above-ground buildings, optimizing the layout of underground pipelines. Buffer analysis, network analysis, path analysis, and geographic weighted regression techniques within the building GIS data system are used to identify and quantify the risk information and construction difficulty of building renovation or expansion. An environmental impact assessment model for the building is established using the building GIS data system. This model is used to analyze above-ground and underground spatial data to assess the environmental impact of building renovation or expansion on the surrounding environment.

[0042] S300: Based on renovation and expansion parameters and spatial data, determine the renovation and expansion plan for the building, and carry out renovation or expansion of the building based on the renovation and expansion plan.

[0043] Based on building GIS data systems and spatial data, multiple simulation models of the building are constructed. Combining the building's renovation and expansion parameters with the simulation models, the renovation or expansion process of the building is simulated. The simulation results of the building's renovation or expansion process are evaluated, and the renovation or expansion plan is determined based on the best-performing simulation result. The building is then renovated or expanded according to the renovation or expansion plan.

[0044] Furthermore, an information sharing platform will be established within the building's GIS data system to integrate various data and information resources, including spatial data, construction plans, and personnel resources. Intelligent algorithms and collaborative work models will be developed to achieve dynamic allocation and optimized utilization of resources. For example, spatial analysis techniques can be used to determine the optimal construction route and resource allocation scheme. A collaborative work platform will be designed to support real-time communication and collaboration among team members, promoting information sharing and teamwork, and improving the overall efficiency of the renovation and expansion plan.

[0045] The building renovation and expansion method provided in this invention combines the building's spatial data with a GIS system to obtain a building GIS data system. The spatial data includes both above-ground and underground spatial data. Based on the building GIS data system, renovation and expansion parameters are determined. These parameters include at least the building's optimal traffic access, construction restriction areas, construction difficulty of the renovation or expansion, risk information, and environmental impact information. Based on these parameters and the spatial data, a renovation and expansion plan is determined, and the building is then renovated or expanded according to this plan. This invention determines renovation and expansion parameters based on spatial data, achieving comprehensive analysis of the spatial data and improving the accuracy of building renovation or expansion. By using the renovation and expansion parameters and spatial data from the building GIS data system, the efficiency of building renovation or expansion is improved.

[0046] Based on the above embodiments, the above-ground and underground space data of a building are combined with a GIS system to obtain a building GIS data system, specifically including steps S110 to S160, each step as follows:

[0047] S110: Spatial data is imported into the GIS system through the software and hardware interfaces of the GIS system. Both the software and hardware interfaces are used to connect the GIS system and the data acquisition equipment.

[0048] S120: Register spatial data in the GIS system to the same coordinate system.

[0049] S130: Filter the registered spatial data to remove noise and outlier data.

[0050] S140: Extract key features from the filtered spatial data to obtain key feature data.

[0051] S150: Segment the key feature data into multiple spatial element data, which include at least building data, ground data, and vegetation data.

[0052] S160: Perform geometric and color calibration on spatial element data, and obtain building GIS data system based on the calibrated spatial element data and GIS system.

[0053] Data acquisition equipment includes 3D scanning equipment and oblique photogrammetry equipment. Point cloud data (spatial data) of the building renovation or expansion site is acquired using this equipment. Software and hardware interfaces for the GIS are pre-designed to ensure data transmission and interaction between the data acquisition equipment and the GIS system. The point cloud data is then imported into the GIS system through these software and hardware interfaces for subsequent processing and analysis.

[0054] The design incorporates data acquisition algorithms to process and calibrate scanned spatial data during the scanning process. These algorithms include point cloud registration, data filtering, feature extraction, point cloud segmentation, and data calibration. Point cloud registration includes Iterative Closest Point (ICP) matching. IPC registers point cloud data from different scanning locations, aligning them in the same coordinate system. Data filtering uses Gaussian filtering to remove noise and outliers from the spatial data, improving its smoothness and accuracy. Feature extraction algorithms include Harris corner detection and feature extraction. These algorithms extract key features from the spatial data. Point cloud segmentation includes K-means clustering. K-means clustering segments the point cloud data into building, ground, and vegetation data to identify different spatial elements such as buildings, ground, and vegetation. Data calibration algorithms are used to perform geometric and color calibration on the spatial data acquired by scanning techniques (including 3D scanning and oblique photogrammetry) to ensure data consistency integrated into the GIS system.

[0055] This invention improves the accuracy of building GIS data systems by filtering, extracting key features, segmenting, and calibrating spatial data, and obtaining a building GIS data system based on a GIS system and calibrated spatial element data.

[0056] Based on the above embodiments, the risk information of building renovation or expansion is determined based on the building GIS data system, specifically including steps S210 to S240, each step as follows:

[0057] S210: Based on the building GIS data system, conduct construction risk assessment on the topography and geomorphology data of the building to obtain the first risk factor of the building. The first risk factor represents the natural disaster of the building.

[0058] S220: Based on the building GIS data system, conduct engineering risk assessment on the underground pipe network data of the building to obtain the second risk factor of the building. The second risk factor characterizes the disasters associated with the underground pipe network of the building.

[0059] S230: Based on the first risk factor and the second risk factor, determine the risk information for renovation or expansion.

[0060] By utilizing techniques such as buffer analysis, path analysis, and geographic weighted regression within a building GIS data system, risk factors associated with the renovation or expansion of buildings are identified and quantified. These risk factors include at least geological hazards, topographic hazards arising from terrain complexity, and natural disasters. Based on the building GIS data system, a construction risk assessment is conducted on the building's topographic and geomorphological data to determine construction difficulty and risk areas, and the first risk factor is identified based on these risk areas. The first risk factor includes at least landslides and geological landslides. An engineering risk assessment is then conducted on the building's underground pipeline network data based on the building GIS data system to identify the building's second risk factors. Spatial analysis is used to determine the layout and key nodes of the underground pipeline network, identify potential construction difficulties and risk points, analyze these risk points, and identify the second risk factor. Furthermore, the building GIS data system utilizes machine learning and data mining techniques to analyze and model the building, identifying and predicting potential third risk factors during the renovation or expansion process. Alternatively, a multi-dimensional risk assessment system can be established to assess design and planning risks, construction technology and engineering risks, environmental and sustainability risks, and economic risks during the building renovation or expansion process, achieving a comprehensive risk assessment of the building renovation or expansion process.

[0061] This invention utilizes a building GIS data system to identify various risk factors during the renovation or expansion of buildings, thereby achieving comprehensive risk identification and improving the safety of building renovation or expansion.

[0062] Based on the above embodiments, and based on the renovation and expansion parameters and spatial data, a renovation and expansion plan for the building is determined, specifically including steps S400 to S700, each step as follows:

[0063] S400: Based on environmental information from spatial data, determine the first model of the building. The first model represents the ground undulations and terrain features of the building within a defined range.

[0064] S500: Based on the above-ground structural information of spatial data, determine the second model of the building. The second model at least represents the building's appearance, structure, and internal layout information.

[0065] S600: Based on underground space information from spatial data, determine the third model of the building. The third model at least represents the location and structure of the building's underground pipelines.

[0066] S700: Based on the first model, the second model, the third model, and the renovation and expansion parameters, the renovation or expansion process of the building is simulated, and the renovation and expansion plan is determined based on the simulation results.

[0067] Develop 3D visualization technology. Using a Digital Elevation Model (DEM) and environmental information (e.g., terrain), a first model is created to display the building's ground undulations and terrain features within a defined area. A second model is created using Building Information Modeling (BIM) and the building's above-ground structural information, providing a comprehensive view of the building's appearance, structure, and internal layout. A third model is constructed based on the building's underground space information, representing the location and structure of underground pipelines, including attributes such as location, depth, and diameter. Furthermore, an interactive visualization interface is designed to update data in the building's GIS data system. Changes in data sources, such as sensor data and real-time measurement data, are monitored and reflected promptly on the visualization interface to ensure users receive the latest information. Data accuracy and timeliness are guaranteed: a data quality monitoring and correction mechanism is developed to ensure the accuracy and consistency of above-ground and underground space data. A real-time data processing and rendering engine is established to improve the efficiency of data processing and visualization, ensuring the timeliness and accuracy of results. Based on the first, second, and third models and the renovation / expansion parameters, the renovation or expansion process of the building is simulated. The renovation / expansion plan for the building is determined based on the best simulation results.

[0068] The embodiments of the present invention determine the renovation and expansion scheme based on the first model, the second model, the third model and the renovation and expansion parameters, thereby improving the accuracy of the network in determining the renovation and expansion scheme and improving the efficiency of building renovation or expansion.

[0069] Based on the above embodiments, environmental impact information is determined using a building GIS data system, specifically including steps S250 to S270, each step as follows:

[0070] S250: Based on the building GIS data system, identify multiple environmental impact factors of buildings, including at least land use change information, water consumption information, and ecosystem damage information.

[0071] S260: Set different weights and evaluation indicators for environmental impact factors.

[0072] S270: Determine environmental impact information based on the weights and evaluation indicators of all environmental impact factors.

[0073] By utilizing a building GIS data system, geographic information about buildings, such as natural environment, ecosystem, and human activities, is further integrated to construct an environmental impact assessment model. This model assesses the environmental impacts of building renovations or expansions on the surrounding area, including factors such as land use change, water consumption, and ecosystem damage. Different weights and evaluation indicators are assigned to each environmental impact factor according to the model. Based on the weights and evaluation indicators of all environmental impact factors, the environmental impact information of building renovations or expansions on the surrounding environment is evaluated.

[0074] This invention utilizes a building GIS data system to determine environmental impact information, enabling a comprehensive assessment of the environmental impact of building renovation or expansion processes, thereby improving the efficiency of building renovation or expansion.
