[0031] In the related art, in order to improve the efficiency of construction in mountainous areas, it is necessary to plan the construction site in advance through three-dimensional modeling. However, the existing site layout planning method is to first design a two-dimensional site layout plan, and then generate a three-dimensional model based on the two-dimensional site layout plan. This method is inefficient and difficult to achieve forward design of construction site layout in mountainous areas, and cannot meet user needs.

[0032] In order to solve the above problems, the present disclosure provides a site layout method for temporary projects in mountainous areas, which obtains terrain spatial data, site layout condition data and a model to be planned in the site layout area; generates multiple three-dimensional pre-selected layout schemes based on the terrain spatial data, condition data and the model to be planned; evaluates the multiple three-dimensional pre-selected layout schemes according to preset rules to obtain evaluation results; selects a target scheme from the multiple three-dimensional pre-selected layout schemes according to the evaluation results; obtains location information of a main road adjacent to the site layout area; generates a three-dimensional model of a temporary road connecting the site layout area and the main road according to the terrain spatial data, the target scheme and the location information, and obtains a forward design scheme for temporary projects in mountainous areas including the target scheme and the three-dimensional model of the temporary road, thereby improving the generation efficiency of three-dimensional site layout schemes in mountainous areas and realizing the forward design of construction site layout in mountainous areas.

[0033] Figure 1 is a flow chart showing a method for site layout of a temporary project in a mountainous area according to an exemplary embodiment. Figure 1 As shown, it should be noted that the site layout method for temporary engineering in mountainous areas according to the embodiment of the present disclosure is applied to the site layout device for temporary engineering in mountainous areas. Figure 1 As shown, the method may include the following steps:

[0034] Step 101: Acquire terrain spatial data of the site layout area, site layout condition data and a model to be planned.

[0035] In some embodiments of the present disclosure, the model to be planned is obtained from a pre-established model library, and the model library includes multiple sub-model libraries. The multiple sub-model libraries store different types of models, for example, they may include: the model stored in the model library is used for forward design of construction site layout plans in mountainous areas; the model includes parameter information corresponding to the model.

[0036] In addition, the relevant component models in the model library can be generated based on the component parameters provided by the component manufacturer, so as to facilitate the manufacturer to perform assembly production according to the three-dimensional layout and forward design scheme of the temporary project.

[0037] In some embodiments of the present disclosure, the model library may include a static model library and a parametric model library, wherein the static model library includes a plurality of preset 3D models, covering various elements commonly seen in construction sites, such as machinery and equipment, infrastructure, temporary facilities, vegetation, construction personnel, roads, sites, and various signboards. These models are made according to standard sizes to ensure authenticity and accuracy in site layout; the parametric model library contains models that can be dynamically adjusted according to specific needs, such as steel processing sheds, living areas, office areas, and publicity signs. These models can be automatically generated based on input parameters (such as size, capacity, material, etc.), providing greater flexibility and customization capabilities.

[0038] In some embodiments of the present disclosure, the terrain spatial data may include satellite vector maps and oblique photography data, and the satellite vector maps and the oblique photography data may be fused to obtain a three-dimensional terrain model of the site layout area.

[0039] It should be noted that the site layout condition data may include demand information and industry specifications for construction site layout in mountainous areas. The generated construction site layout plan in mountainous areas shall meet the above constraints.

[0040] In one embodiment, the site layout condition data may be stored in a knowledge base, and the site layout condition data may include various standards, specifications and guidelines related to site layout, such as engineering design documents, topographic spatial data of the temporary engineering alternative site area, engineering geological and hydrological data, site layout condition data, temporary engineering component models, site forward design standards, construction specifications, project delivery requirements, safety and environmental standards, and construction specifications applicable to general and special sites.

[0041] Step 102: Generate multiple three-dimensional pre-selected layout plans based on terrain spatial data, condition data and the model to be planned.

[0042] In some embodiments of the present disclosure, step 102 may specifically include the following steps:

[0043] Step a1, using a genetic algorithm and / or an annealing algorithm, generating a plurality of first pre-selected solutions according to terrain spatial data, site layout condition data and a model to be planned.

[0044] In one embodiment, a genetic algorithm may be used to generate a plurality of first pre-selected solutions based on terrain spatial data, condition data and a model to be planned.

[0045] In another embodiment, an annealing algorithm may be used to generate a plurality of first pre-selected solutions according to the terrain spatial data, condition data and the model to be planned.

[0046] In another embodiment, a genetic algorithm and an annealing algorithm may be used to generate a plurality of first pre-selected solutions according to the terrain spatial data, the conditional data and the model to be planned. For example, a genetic algorithm is used to generate an initial solution for global planning according to the terrain spatial data, the conditional data and the model to be planned, and an annealing algorithm is used to locally optimize the initial solution to obtain a pre-selected solution.

[0047] In one embodiment, the constraint conditions can be obtained from the site layout condition data, and a constraint satisfaction problem CSP solver is used to solve the problem in the process of generating the pre-selected solution. The constraint conflict detection can also be performed on the solution result to deal with the contradictory constraint conditions.

[0048] Step a2: generating a feature vector corresponding to each first pre-selected solution among the plurality of first pre-selected solutions.

[0049] In one embodiment, each first pre-selected option is represented as a feature vector, which may include the following elements: the area ratio of each functional area, the relative position of major facilities, the topological structure of the road network, and terrain utilization indicators (such as flatness, slope utilization, etc.).

[0050] Step a3: Calculate the similarity index value of each first pre-selected solution according to the feature vector.

[0051] In one embodiment, the similarity index value may be calculated by calculating the Euclidean distance or cosine similarity corresponding to each first pre-selected solution.

[0052] Step a4: according to the similarity index value, remove the pre-selected schemes with similarity greater than a preset threshold value from the plurality of first pre-selected schemes, and determine the remaining pre-selected schemes as a plurality of three-dimensional pre-selected arrangement schemes.

[0053] In some embodiments of the present disclosure, the first pre-selected plan with a higher similarity index value can also be adjusted to reduce the similarity of the plan, such as exchanging different functional areas of the plan, randomly selecting two functional areas to exchange positions, moving major facilities to new locations, reconstructing the road network, and modifying some road connection relationships.

[0054] In other embodiments of the present disclosure, the similarity of the first pre-selected scheme can also be reduced through a genetic algorithm, such as selecting two parent schemes; identifying the main differences between the parents; giving priority to the difference points for information exchange during crossover; and making local adjustments to the crossover results to further increase the differences. For another example, the mutation rate is dynamically adjusted according to the diversity of the population. When the current diversity is lower than the target value, the mutation rate is increased; when the current diversity is higher than the target value, the mutation rate is reduced; the mutation rate is always maintained between the preset minimum and maximum values. For another example, the K-means algorithm is used to cluster the current population, and in the selection operation, it is ensured that representative individuals are selected from each cluster; the number of clusters is dynamically adjusted to balance diversity and quality.

[0055] In some embodiments of the present disclosure, before step 102, the method may further include the following steps:

[0056] Step b1, after receiving a material matching indication for a first model in the to-be-planned models input by a user, a pre-trained neural network model is used to extract features of the first model to obtain first feature information of the first model.

[0057] It should be noted that the model to be planned can be a model that comes with the system, or a model that is imported from outside the system by other means. In order to generate a construction site layout plan that meets actual needs, its material needs to be displayed on the model, but some imported models do not have configured materials, so the material information needs to be configured. However, in the prior art, the staff is required to manually configure the relevant parameters, which is not only inefficient, but may also fail to meet the standards of relevant industry specifications. Therefore, the material parameters can be automatically assigned to the model.

[0058] In one embodiment, the first feature information of the model may include features such as color distribution, texture pattern, and reflection characteristics.

[0059] Step b2: Generate a first feature vector based on the first feature information.

[0060] In one embodiment, a plurality of first feature information of the first model may be combined into a first feature vector.

[0061] Step b3: Select a second feature vector that matches the first feature vector from a preset material feature database.

[0062] In some embodiments of the present disclosure, step b3 may specifically include the following steps:

[0063] respectively calculating the similarity between the first feature vector and each second feature vector in the material feature database;

[0064] The second eigenvector corresponding to the maximum similarity value is selected to obtain a second eigenvector matching the first eigenvector.

[0065] In one embodiment, a method such as cosine similarity or Euclidean distance may be used to calculate similarity, and the material with the highest similarity is selected as the matching result.

[0066] Step b4, selecting material feature parameters corresponding to the second feature vector in the material feature database.

[0067] It can be understood that the material feature database stores the second feature vector, material feature parameters, and the correspondence between different second feature vectors and different material features.

[0068] Step b5, rendering the first model according to the material characteristic parameters to obtain a rendered first model.

[0069] Step 103 , evaluating multiple three-dimensional pre-selected layout solutions according to preset rules to obtain evaluation results.

[0070] In one embodiment, a multi-dimensional scoring model based on the analytic hierarchy process (AHP) can be used to evaluate the three-dimensional pre-selected layout scheme based on relevant evaluation indicators such as economy, safety, environmental protection, and efficiency. Multiple evaluation indicator values ​​can also be weighted and summed to obtain a comprehensive evaluation indicator value, that is, to obtain the above-mentioned evaluation result.

[0071] Step 104 , selecting a target solution from a plurality of three-dimensional pre-selected layout solutions according to the evaluation result.

[0072] In some embodiments of the present disclosure, after step 104, the method may further include the following steps:

[0073] In response to a user's adjustment operation on the second structure in the target solution, determining whether the adjustment operation satisfies a preset condition;

[0074] When multiple three-dimensional pre-selected layout solutions meet preset conditions, the target solution is updated according to the adjustment operation.

[0075] In one embodiment, after selecting a target solution, the user can adjust the layout of the model in the target solution according to actual needs. In order to ensure that the adjusted solution can meet the site layout conditions, the target solution can be updated according to the adjustment operation when multiple three-dimensional pre-selected layout solutions meet the preset conditions. If the preset conditions are not met, relevant prompts that meet the preset conditions are output.

[0076] Step 105: Acquire location information of main roads adjacent to the site layout area.

[0077] Step 106, generating a three-dimensional model of a temporary road connecting the site layout area and the main road based on the terrain spatial data, the target solution and the location information, and obtaining a forward design solution for temporary works in mountainous areas including the target solution and the three-dimensional model of the temporary road.

[0078] It should be noted that the above-mentioned three-dimensional site layout plan may be a plan for arranging the site of a temporary project; the above-mentioned forward design plan may include temporary projects including roads, communication power and water supply lines, residences and material yards, beam yards and other prefabricated component yards, explosives depots, air compressor rooms, mixing stations, construction site laboratories and other production areas, as well as living areas, and also includes layout plans for supporting facilities such as sewage treatment and oxygen supply.

[0079] In some embodiments of the present disclosure, after obtaining the forward design scheme for temporary engineering in mountainous areas, a multi-perspective switching function can be implemented based on the Unreal Engine, supporting first-person walking perspective, driving perspective, and free flight perspective. A camera controller is implemented. An intelligent path generation algorithm is developed to automatically create the most representative roaming route. An AI-controlled camera is implemented. An interactive annotation tool is designed to allow users to mark problem points and optimization suggestions during roaming.

[0080] In some embodiments of the present disclosure, the forward design plan for temporary engineering projects in mountainous areas can be output in any one or more of the following ways: two-dimensional CAD drawing output; intermediate format file export; 3D model export; data report generation; interactive Web display; VR / AR content output.

[0081] Among them, 2D CAD drawing output refers to the generation of CAD drawings that meet engineering standards, including general plan, partition details, section drawings, etc. It can use 3D to 2D projection algorithms to achieve orthogonal projection and perspective projection, and accurately generate plan and section drawings;

[0082] Intermediate format file export refers to supporting the output of intermediate format files that are compatible with various project management platforms, facilitating data sharing and display. The data structure mapper is used to convert the internal data model into the format of various project management platforms, and the export function of common data exchange formats such as XML and JSON is realized. The metadata wrapper is used to ensure that the exported data contains the necessary context information;

[0083] 3D model export means supporting the export of complete 3D site models into common 3D formats for subsequent processing in other software. Supports export of multiple 3D formats, such as FBX, OBJ, etc., develops a level of detail LOD generator, allows users to select models of different precision for export, designs material and texture packaging tools to ensure the integrity of the exported model, implements the block export function of large models, and handles the situation of super-large sites;

[0084] Data report generation refers to the automatic generation of various statistical reports, including area statistics, equipment lists, material requirements, etc., developing a configurable report template engine, supporting custom report formats, implementing data aggregation and analysis functions, automatically calculating key statistical indicators, and designing interactive chart generators to allow users to customize data visualization methods. Develop report export functions to support multiple formats such as PDF and Excel;

[0085] Interactive Web display refers to generating interactive 3D site display pages that can be viewed in a browser and developing a lightweight 3D scene rendering engine;

[0086] VR / AR content output refers to supporting the generation of site experience content suitable for virtual reality VR and augmented reality AR devices, and developing scene converters compatible with mainstream VR / AR devices. Realizing VR / AR scene conversion, implementing an interactive point marking system, supporting the addition of information tags in VR / AR environments, implementing interactive point management in VR / AR environments, and designing spatial audio generators to enhance the immersion of virtual environments.

[0087] In some embodiments of the present disclosure, step 106 may specifically include the following steps:

[0088] Step c1, using a path planning algorithm, performing path planning between the site layout area and the main road according to terrain spatial data, target plan and location information, and obtaining multiple planning results.

[0089] It is understandable that after the target plan is generated, it is necessary to generate a shortcut connecting the site layout area and the main road for personnel passage and material transportation.

[0090] In one embodiment, the path planning algorithm may be an A* algorithm.

[0091] Step c2, obtaining the constraint conditions associated with the access road, wherein the constraint conditions are selected from the site layout condition data.

[0092] Step c3: for each of the multiple planning results, determine whether the planning result meets the constraint condition.

[0093] Step c4, selecting a planning result that meets the constraint conditions from multiple planning results as the planning path of the shortcut.

[0094] Step c5, generating a three-dimensional model of the access road based on the planned path and terrain spatial data.

[0095] In some embodiments of the present disclosure, step c5 may specifically include the following steps:

[0096] Generate an initial access road model according to the planned path;

[0097] Obtain the terrain features within the neighborhood of the initial access road model and determine the types of terrain features;

[0098] Determine the interpolation method corresponding to the type;

[0099] The three-dimensional model of the sidewalk and the transition segment model of the neighborhood of the three-dimensional model of the sidewalk are generated in an interpolation manner, so as to obtain the three-dimensional model of the sidewalk including the initial sidewalk model and the transition segment model.

[0100] It is understandable that due to the complex terrain in mountainous areas, in order to more accurately generate the layout plan for construction sites in mountainous areas, after the access road model is generated, it is necessary to perform transition processing between the access road model and the neighborhood model. In an environment with complex terrain, using different interpolation methods to generate transition sections for different terrains can improve the accuracy of the model.

[0101] In one embodiment, the correspondence between different terrains and non-interpolation methods can be preset. After identifying the terrain feature type of the target area, an interpolation method matching the type is selected to generate a three-dimensional model of the sidewalk and a transition segment model of the neighborhood of the three-dimensional model of the sidewalk, and a three-dimensional model of the sidewalk including an initial sidewalk model and a transition segment model is obtained.

[0102] As an embodiment, the above interpolation methods may include any one or more of the following: such as Kriging method, inverse distance weighted method IDW; digital elevation model DEM processing: such as filtering, resampling technology; slope stability analysis: such as limit equilibrium method, finite element analysis; GIS-based ecosystem model.

[0103] For example, Kriging: Applicable to terrain with gentle changes, such as hills and plains. Considering spatial correlation, it is suitable for processing irregularly distributed sampling points. It is suitable for mapping large-scale landform features, such as river valley plains or gently sloping hilly areas. Inverse distance weighted method (IDW): Applicable to mapping local undulating terrain such as small hills or intermountain basins. It has fast calculation speed and is suitable for processing areas with dense sampling points.

[0104] In some embodiments of the present disclosure, the site layout condition data includes ecological and environmental protection constraints for the site layout area, and the construction site layout plan in mountainous areas meets the ecological and environmental protection constraints. For example, for areas with higher altitudes, relevant constraints for oxygen generators, oxygen supplementation cabins, oxygen supply pipelines, etc. are added.

[0105] In addition, the model library is equipped with relevant models for photovoltaic power generation to achieve the purpose of ecological and environmental protection.

[0106] According to the site layout method for temporary projects in mountainous areas proposed in the embodiment of the present disclosure, terrain spatial data, site layout condition data and a model to be planned of the site layout area are obtained; multiple three-dimensional pre-selected layout schemes are generated based on the terrain spatial data, condition data and the model to be planned; the multiple three-dimensional pre-selected layout schemes are evaluated according to preset rules to obtain evaluation results; according to the evaluation results, a target scheme is selected from the multiple three-dimensional pre-selected layout schemes; the position information of the main road adjacent to the site layout area is obtained; according to the terrain spatial data, the target scheme and the position information, a three-dimensional model of a temporary road connecting the site layout area and the main road is generated to obtain a construction site layout plan in mountainous areas, thereby improving the generation efficiency of the three-dimensional site layout plan in mountainous areas and realizing the forward design of the construction site layout in mountainous areas.
