[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 by means of three-dimensional modeling. However, the existing site layout planning method is to first design a two-dimensional site layout scheme, and generate a three-dimensional model based on the two-dimensional site layout scheme. This method is low in efficiency and difficult to realize the forward design of the construction site layout in mountainous areas, and cannot meet the user's demand.

[0032] To solve the above problems, the disclosure provides a site layout method for temporary engineering in mountainous areas, which comprises the following steps: acquiring topographic spatial data, site layout condition data and a to-be-planned model of a site layout area; generating a plurality of three-dimensional pre-selected layout schemes based on the topographic spatial data, the condition data and the to-be-planned model; evaluating the plurality of three-dimensional pre-selected layout schemes according to a preset rule to obtain an evaluation result; selecting a target scheme from the plurality of three-dimensional pre-selected layout schemes according to the evaluation result; acquiring position information of a main road adjacent to the site layout area; generating a three-dimensional model of a shortcut connecting between the site layout area and the main road according to the topographic spatial data, the target scheme and the position information, to obtain a forward design scheme for temporary engineering in mountainous areas comprising the target scheme and the three-dimensional model of the shortcut, thereby improving the generation efficiency of the three-dimensional site layout scheme in mountainous areas and realizing the forward design of the construction site layout in mountainous areas.

[0033] Figure 1 is a flowchart of a site layout method for temporary engineering in mountainous areas according to an exemplary embodiment, as shown inFigure 1 It should be noted that the site layout method of temporary works in mountainous areas of the embodiments of the present disclosure is applied to a site layout device for temporary works in mountainous areas. As shown in Figure 1 The method can include the following steps:

[0034] In step 101, topographic spatial data, site layout condition data, and a to-be-planned model of a site layout area are obtained.

[0035] In some embodiments of the present disclosure, the to-be-planned model is obtained from a pre-established model library. The model library includes a plurality of sub-model libraries, and the plurality of sub-model libraries store different types of models. For example, the model library can include models for forward design of a construction site layout scheme in a mountainous area. The models include corresponding parameter information of the models.

[0036] In addition, the related component models in the model library can be generated according to the component parameters provided by the component manufacturers, so as to facilitate the production of the manufacturers according to the three-dimensional layout and the forward design scheme of the temporary works.

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

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

[0039] It should be noted that the site layout condition data can include demand information and industry specifications and other constraint conditions for construction site layout in mountainous areas. The generated construction site layout scheme in mountainous areas should meet the above constraint conditions.

[0040] In one embodiment, the site arrangement condition data can be stored in the knowledge base, and the site arrangement condition data can include various standards, norms and guidelines related to site arrangement. For example, engineering design documents, topographic spatial data of temporary engineering alternative site areas, engineering geology and hydrology data, site arrangement 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] In step 102, based on the topographic spatial data, condition data and the model to be planned, a plurality of three-dimensional preselected arrangement schemes are generated.

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

[0043] In step a1, a genetic algorithm and / or an annealing algorithm is used to generate a plurality of first preselected schemes according to the topographic spatial data, the site arrangement condition data and the model to be planned.

[0044] In one embodiment, a genetic algorithm can be used to generate a plurality of first preselected schemes according to the topographic spatial data, the condition data and the model to be planned.

[0045] In another embodiment, an annealing algorithm can be used to generate a plurality of first preselected schemes according to the topographic spatial data, the condition data and the model to be planned.

[0046] In yet another embodiment, a genetic algorithm and an annealing algorithm can be used to generate a plurality of first preselected schemes according to the topographic spatial data, the condition data and the model to be planned. For example, a genetic algorithm is used to generate an initial scheme for global planning according to the topographic spatial data, the condition data and the model to be planned, and an annealing algorithm is used to locally optimize the initial scheme to obtain a preselected scheme.

[0047] In one embodiment, constraint conditions can be obtained from the site arrangement condition data, a constraint satisfaction problem (CSP) solver can be used to solve the constraint conditions during the generation of the preselected schemes, and constraint conflict detection can be performed on the solution to handle contradictory constraint conditions.

[0048] In step a2, a feature vector corresponding to each of the plurality of first preselected schemes is generated according to each of the plurality of first preselected schemes.

[0049] In one embodiment, each first preselected scheme can be represented as a feature vector, which can include the following elements: the area proportion of each functional area, the relative position of main facilities, the topological structure of road networks, and topographic utilization indicators (such as flatness, slope utilization, etc.).

[0050] Step a3, calculating the similarity index value of each first preselected scheme according to the eigenvector.

[0051] In one embodiment, the similarity index value can be calculated by calculating the Euclidean distance or cosine similarity of each first preselected scheme.

[0052] Step a4, removing the preselected schemes with similarity greater than the preset threshold from the plurality of first preselected schemes according to the similarity index value, and determining the remaining preselected schemes as the plurality of three-dimensional preselected layout schemes.

[0053] In some embodiments of the present disclosure, the first preselected scheme with a high similarity index value can also be adjusted to reduce the similarity of the scheme, for example, exchanging different functional areas of the scheme, randomly selecting two functional areas to exchange positions, moving the main facilities to a new position, reconstructing the road network, and modifying part of the road connection relationship.

[0054] In some embodiments of the present disclosure, the similarity of the first preselected scheme can also be reduced by a genetic algorithm, for example, selecting two parent schemes; identifying the main difference points between the parents; when crossing, preferentially selecting the difference points for information exchange; and locally adjusting the crossing result to further increase the difference. For another example, the mutation rate is dynamically adjusted according to the population diversity. 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 decreased; and 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, representative individuals are ensured to be selected from each cluster; and the number of clusters is dynamically adjusted to balance the diversity and quality.

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

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

[0057] It should be noted that the to-be-planned model can be a model provided by the system itself, or a model imported from outside the system by other means. In order to generate a construction site layout scheme that meets the actual demand, the material of the model needs to be displayed, but some imported models do not have configured materials, so the material information needs to be configured. However, in the prior art, the relevant parameters need to be manually configured by the staff, which is not only low in efficiency, but also may not meet the standards of relevant industry specifications, so the model can be automatically assigned with material parameters.

[0058] In an embodiment, the first feature information of the model can include color distribution, texture pattern, reflection characteristics, and the like.

[0059] Step b2, generating a first feature vector based on the first feature information.

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

[0061] Step b3, selecting a second feature vector matching the first feature vector from a preset material feature database.

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

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

[0064] Selecting the second feature vector corresponding to the maximum similarity value to obtain the second feature vector matching the first feature vector.

[0065] In an embodiment, cosine similarity or Euclidean distance and the like can be used for similarity calculation, and the material with the highest similarity is selected as the matching result.

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

[0067] It can be understood that the second feature vector, the material feature parameter, and the correspondence between different second feature vectors and different material features are stored in the material feature database.

[0068] Step b5, performing a rendering operation on the first model according to the material feature parameter to obtain a rendered first model.

[0069] Step 103, evaluating a plurality of three-dimensional preselected arrangement schemes according to a preset rule to obtain an evaluation result.

[0070] In an embodiment, a multi-dimensional scoring model based on the analytic hierarchy process (AHP) can be used to evaluate the three-dimensional preselected arrangement schemes in terms of economic, safety, environmental protection, efficiency, and the like. The multi-dimensional scoring model can also be used to weight and sum a plurality of evaluation index values to obtain a comprehensive evaluation index value, i.e., the above-mentioned evaluation result.

[0071] Step 104, selecting a target scheme from the plurality of three-dimensional preselected arrangement schemes according to the evaluation result.

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

[0073] In response to the adjustment operation of the user on the second structure in the target scheme, it is determined whether the adjustment operation meets the preset condition;

[0074] In the case where the plurality of three-dimensional preselected arrangement schemes meet the preset condition, the target scheme is updated according to the adjustment operation.

[0075] In one embodiment, after the target scheme is selected, the user can make layout adjustment on the model in the target scheme according to actual needs. In order to ensure that the adjusted scheme can meet the site layout condition, the target scheme can be updated according to the adjustment operation in the case where the plurality of three-dimensional preselected arrangement schemes meet the preset condition, and a related prompt meeting the preset condition is output in the case where the preset condition is not met.

[0076] In step 105, the position information of the main road adjacent to the site layout area is obtained.

[0077] In step 106, a three-dimensional model of a shortcut connected between the site layout area and the main road is generated according to the topographic spatial data, the target scheme and the position information, and a mountainous area temporary engineering forward design scheme including the target scheme and the three-dimensional model of the shortcut is obtained.

[0078] It should be noted that the above-mentioned three-dimensional site layout scheme can be a scheme for arranging the site of the temporary engineering; and the above-mentioned forward design scheme can include an arrangement scheme for the temporary engineering including a road, a communication power and water supply line, a site and a material field, a precast component field such as a beam field, an explosive warehouse, an air compressor room, a mixing station, a construction site laboratory and a production area, and a living area, and further including a sewage treatment, oxygen supply and other supporting facilities.

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

[0080] In some embodiments of the present disclosure, the mountainous area temporary engineering forward design scheme 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; and VR / AR content output.

[0081] The two-dimensional CAD drawing output refers to generating a CAD drawing conforming to the engineering standard, including a general plan, a subarea detail map and a section view, and can use a 3D to 2D projection algorithm to realize orthogonal projection and perspective projection, and accurately generate a plan and a section view.

[0082] Intermediate format file export refers to supporting the output of intermediate format files adapted to various project management platforms, facilitating data sharing and display, using a data structure mapper to convert internal data models into various project management platform formats, implementing XML, JSON, and other common data exchange format export functions, using a metadata wrapper to ensure that exported data contains necessary context information.

[0083] 3D model export refers to 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 to allow users to select different precision models for export, designs a material and texture packing tool to ensure the integrity of exported models, and implements large model chunking export functions to handle ultra-large site scenarios.

[0084] Data report generation refers to automatically generating various statistical reports, including area statistics, equipment lists, material requirements, etc. Develops a configurable report template engine to support custom report formats, implements data aggregation and analysis functions, automatically calculates key statistical indicators, designs an interactive chart generator to allow users to customize data visualization, and develops a report export function to support multiple formats such as PDF and Excel.

[0085] Interactive Web presentation refers to generating interactive 3D site presentation 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 a scene converter compatible with mainstream VR / AR devices. Implements VR / AR scene conversion, implements an interactive point marking system, supports adding information tags in the VR / AR environment, implements interactive point management in the VR / AR environment, and designs a spatial audio generator to enhance the immersion of the virtual environment.

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

[0088] Step c1, using a path planning algorithm to plan a path between the site layout area and the main road according to the terrain spatial data, the target scheme, and the position information, to obtain a plurality of planning results.

[0089] It can be understood that after the target scheme is generated, a shortcut connecting the site layout area and the main road needs to be generated for personnel passage and material transportation.

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

[0091] Step c2, obtaining the constraint condition associated with the detour. The constraint condition is selected from the site layout condition data.

[0092] Step c3, for each of the plurality of planning results, determining whether the planning result meets the constraint condition.

[0093] Step c4, selecting the planning result meeting the constraint condition from the plurality of planning results as the planning path of the detour.

[0094] Step c5, generating the detour three-dimensional model according to the planning path and the terrain space data.

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

[0096] generating an initial detour model according to the planning path;

[0097] obtaining the terrain feature within the neighborhood of the initial detour model, and determining the type of the terrain feature;

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

[0099] generating the transition segment model of the detour three-dimensional model and the neighborhood of the detour three-dimensional model according to the interpolation method, to obtain the detour three-dimensional model including the initial detour model and the transition segment model.

[0100] It can be understood that, due to the complex terrain in mountainous areas, in order to more accurately generate the construction site layout scheme in mountainous areas, after generating the detour model, transition processing needs to be performed between the detour model and the neighborhood model. In a complex terrain environment, different interpolation methods are used to generate transition segments for different terrains, which can improve the accuracy of the model.

[0101] In an embodiment, a correspondence relationship between different terrains and interpolation methods can be preset. After identifying the terrain feature type of the target region, the interpolation method matched with the type is selected to generate the transition segment model of the detour three-dimensional model and the neighborhood of the detour three-dimensional model, to obtain the detour three-dimensional model including the initial detour model and the transition segment model.

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

[0103] For example, Kriging method: suitable for gently changing terrain, such as hilly, plains. Consider spatial correlation, suitable for processing irregularly distributed sampling points. Suitable for drawing large-scale topographic features, such as valley plains or gentle hilly areas. Inverse distance weighted method (IDW): suitable for drawing local relief terrain such as small hills or intermountain basins. Fast calculation speed, suitable for processing areas with dense sampling points.

[0104] In some embodiments of the present disclosure, the site arrangement condition data includes ecological environmental protection constraints for the site arrangement area, and the mountainous area construction site arrangement scheme meets the ecological environmental protection constraints. For example, for areas with high altitudes, relevant constraints for oxygen generators, oxygen supplement cabins, and oxygen supply pipelines are added.

[0105] In addition, the model library is configured with a related model for photovoltaic power generation to achieve the purpose of ecological environmental protection.

[0106] According to the site arrangement method for temporary projects in mountainous areas proposed in the embodiments of the present disclosure, the topographic spatial data of the site arrangement area, the site arrangement condition data, and the to-be-planned model are obtained; based on the topographic spatial data, the condition data, and the to-be-planned model, a plurality of three-dimensional preselected arrangement schemes are generated; the plurality of three-dimensional preselected arrangement schemes are evaluated according to a preset rule to obtain evaluation results; a target scheme is selected from the plurality of three-dimensional preselected arrangement schemes according to the evaluation results; the position information of a main road adjacent to the site arrangement area is obtained; a three-dimensional model of a shortcut connected between the site arrangement area and the main road is generated according to the topographic spatial data, the target scheme, and the position information, and a mountainous area construction site arrangement scheme is obtained, thereby improving the generation efficiency of the three-dimensional site arrangement scheme for the mountainous area and realizing the forward design of the construction site arrangement in the mountainous area.
