Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0048] In the invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the invention can be understood according to the specific circumstances.

[0049] Before describing the construction site arrangement method of the present invention, the considerations before proposing the present invention are briefly described to better understand the present invention, as follows:

[0050] The layout of the construction site is to study the relationship between the facilities in the construction site. The implicit relationship network between the facilities affects the placement of the facilities and the order of the facilities layout, determines the importance of the facilities, and restricts the choice of construction plans. The evaluation of construction site optimization can be considered from multiple aspects such as transportation cost, green construction, safety, and resource utilization. The UAV oblique photography technology has advantages in engineering quantity extraction and real-time safety monitoring. Therefore, the construction site layout based on BIM technology and oblique photography technology mainly considers the two dimensions of transportation cost and safety risk, and explores the relationship between the facilities on the construction site to achieve the effect of reducing transportation costs and reducing safety risks.

[0051] Please refer to Figures 1 to 10 The construction site layout method of the present invention comprises the following steps:

[0052] First, step S1 is executed to construct an oblique photography model and a BIM model of the construction site.

[0053] For further information, please refer to Figure 5 ,This embodiment constructs a BIM model of the construction site based on Revit software.

[0054] Specifically, before constructing the BIM model of the construction site, importing the architectural CAD drawings of the construction site into the BIM modeling software can realize the conversion of the 2D geometric model into a 3D digital model. The spatial characteristics of the building can be visualized through the parametric modeling process. The specific process of constructing the BIM model of the construction site is as follows:

[0055] (1) Create elevations and axis grids. Open the Revit software and execute the "Elevation" and "Axis Grid" commands to establish a three-dimensional spatial coordinate system of field, width, and height to ensure that the "family" added later is in the correct position.

[0056] (2) Establishment of civil engineering model. The core of Revit software modeling is to parameterize the element information, add conventional component families such as walls, columns, beams and slabs to the corresponding positions in the drawings, and establish the project civil engineering model.

[0057] (3) Establishment of electromechanical pipeline model. According to professional classification, pipelines can be divided into water supply and drainage pipes, power and weak electric wire pipes, ventilation and air conditioning HVAC pipelines. There are many types of pipelines and their layout is intricate. In the modeling process, it is necessary to adopt a classification and layered approach to establish them one by one, so as to provide a model basis for the later in-depth design of electromechanical pipelines, collision inspection, auxiliary drawings, etc.

[0058] Furthermore, the process of constructing the oblique photography model of the construction site includes the following steps:

[0059] S101, please refer to Figure 1 , use a drone equipped with an oblique photography system to take oblique photography of the construction site to obtain image data of the construction site (i.e. data collection); specifically, the preparation work required before image data collection is as follows:

[0060] Before the drone takes off, a pre-flight check must be performed, including: 1) whether the remote control, battery, and mobile device are fully charged; 2) whether the camera and gimbal are working properly; 3) whether they can be matched with the mobile software. Data collection is performed according to mission requirements. Plan the flight trajectory of the drone in advance, and observe whether there are any obstacles on site that interfere with the flight route of the drone. Secondly, the weather conditions must be confirmed. In order to ensure the safety of people and equipment within the flight range of the drone, weather conditions such as wind speeds above level 5, snow, rain, and fog are not suitable for flying. Ensure full coverage of the photography area, and optimize parameters such as heading, altitude, and gravity to improve the quality of oblique photography.

[0061] S102, please refer to Figure 2 and Figure 3 , analyze and process the image data of the construction site obtained based on the Context Capture software (i.e., data import) to generate a rough 3D mesh model of the construction site; for details, please refer to Figure 3 Context Capture software matches images by identifying the same feature points between multiple photos. Then, it calculates the positional relationship between the images through these common feature points, imports relevant data, and generates a rough 3D mesh model through point cloud data.

[0062] S103, please refer to Figure 4, optimize and refine the rough 3D mesh model, and map the texture of the original photo of the construction site to the rough 3D mesh model to enhance the sense of reality, so as to generate the oblique photography model of the construction site. At this time, if it is used in related applications, the corresponding coordinates, elevation, distance and other data can be easily obtained on the oblique photography model.

[0063] Next, please refer to Figure 6 , execute step S2, fuse the oblique photography model and the BIM model based on the Skyline platform to generate a fusion model.

[0064] Specifically, S2 includes the following steps:

[0065] S21: Perform model data fusion to fuse the oblique photography model, the BIM model, and the two-dimensional topographic map, the image map, and the elevation data into one map;

[0066] S22: Perform spatial business data fusion to fuse the graph obtained after model data fusion with the business data table to generate a fusion model in which graphs and tables are linked.

[0067] Since the real-life 3D model (i.e., the oblique photography model) uses the WGS84 coordinate system, while the BIM model uses a relative coordinate system, it is necessary to align the spatial positions of the two models. The BIM model is regarded as the source model and the real-life 3D model as the target model. The associative mapping of model attributes and geometric figures is achieved through the fusion of elements, attribute structure and classification coding.

[0068] Next, please refer to Figure 7 , executing step S3, importing the initial layout plan of the construction site arranged on the BIM model into the fusion model to determine the engineering quantity required for the construction site, the coordinate position and size information of the temporary facilities;

[0069] Next, step S4 is executed to optimize the initial layout plan of the construction site based on the ant colony algorithm on the basis of complying with the site layout constraint rules, so as to obtain an optimized construction site layout plan.

[0070] Specifically, the site layout constraint rules include the following:

[0071] 1) Without affecting the construction, the construction area and production and office area shall be reasonably divided, the material yard shall be arranged, and the construction roads shall be reasonably arranged according to each construction stage to reduce secondary handling and ensure smooth transportation roads;

[0072] 2) Strictly follow the construction process to reduce interference with professional work;

[0073] 3) The layout of facilities shall meet the fire protection requirements of construction, shall not affect the layout of underground pipelines, and the layout of temporary facilities shall not occupy the construction site as much as possible;

[0074] 4) After the overall construction begins, temporary facilities and material yards that affect the construction in the construction area shall be adjusted and relocated accordingly;

[0075] 5) According to the construction process of the cross-construction principle, the construction will be arranged in stages according to time periods. At the same time, the on-site machinery will be arranged according to the geographical, architectural and structural characteristics of the project to meet the needs of the site and the construction process;

[0076] 6) The construction of temporary facilities at the construction site shall not damage the measurement marks of the measurement control network and shall not affect the visibility conditions of the measurement marks;

[0077] 7) During the construction period, an effective drainage system shall be established and routine maintenance shall be carried out to prevent pollution to the surrounding roads, and temporary drainage measures at the construction site shall be smooth and effective, so that there is no water accumulation at ordinary times and the water recedes quickly after rain;

[0078] 8) After the final acceptance, all temporary facilities shall be dismantled by the project owner and removed within 15 days.

[0079] Next, please refer to Figure 8 , execute step S5, and arrange the construction site according to the optimized construction site arrangement plan.

[0080] Preferably, before executing S4, it also includes: according to the degree level of the evaluation index and the weight of the evaluation index, the correlation value between the on-site facilities can be calculated to evaluate the initial layout plan of the construction site as an index evaluation system. Wherein, the evaluation index includes: primary index and secondary index, wherein the primary index includes: transportation cost and safety risk; the secondary index includes: material flow, personnel flow, information flow, risk source, accident probability, and impact degree; the degree level of the evaluation index is set according to the actual situation; the weight of the evaluation index is assigned according to the actual situation, and the weight assignment range is: 1 to 10, the most important one gets 10 points, and the least important one gets 1 point, that is: the larger the assigned value, the more important the current evaluation index is. The weight of the evaluation index can be obtained by interviewing participants or managers, obtaining relevant data through questionnaires, and determining the weight of the evaluation index.

[0081] In order to better understand the degree level and weight concept of the evaluation indicators here, the following takes the logistics relationship as an example:

[0082] The logistics relationship can be expressed by the logistics intensity to indicate the closeness of the relationship between two operating units, which is divided into six levels: A, E, I, O, U, and X. A indicates extremely high logistics intensity; E indicates extremely high logistics intensity; I indicates relatively high logistics intensity; O indicates average logistics intensity; U indicates relatively low logistics intensity; and X indicates negligible logistics intensity. If the six levels AEIOUX are assigned values, and the mutual relationship between the levels is quantified, they are 4, 3, 2, 1, 0, and -1 respectively. Assuming that there are 4 facilities on the construction site, the hierarchical relationship between the 4 facilities is obtained through analysis. By substituting the values, the degree level values ​​of the 4 facilities can be obtained.

[0083] In order to better understand steps S3 to S5, they are explained in detail below: Taking into account the actual situation, the construction site flow lines and functional areas are divided according to the site principles. The division of functional areas is based on the actual division of the fusion model and is the premise of site layout. The functional areas are divided into living areas, office areas, and production areas. Different facilities need to be arranged in different functional areas.

[0084] According to the needs of the on-site construction phase, preliminary site layout is carried out for temporary facilities, mechanical equipment, and personnel production and office needs. The traffic organization, the use of large equipment, the layout of material stacking and processing sites are simulated. Comprehensive consideration of relevant factors such as on-site traffic organization and safety risks is carried out, and the site layout is reasonably carried out on the BIM model (based on the current project site and according to past experience) to determine the initial layout plan of the construction site.

[0085] The initial layout plan of the construction site is imported into the fusion model to determine and extract the engineering quantity required for the construction site, the coordinate position and size information of temporary facilities (i.e., the relevant data of the initial layout plan of the construction site) to determine the material consumption level required for the construction site, in order to provide a reference for the analysis of the initial layout plan of the construction site ( Figure 7 ) to lay the foundation for determining the optimization goals.

[0086] Specifically: Based on the topological relationship between facilities, the aerial survey function of the drone oblique photography technology is used to obtain the coordinates and geometric dimensions of the relevant facilities, and batch data can be extracted to calculate the shortest transportation distance, reduce secondary handling, and reduce transportation costs. The facility engineering statistics table, coordinates and geometric dimensions extracted in this embodiment are shown in Table 1:

[0087] Table 1 Facility engineering quantities, coordinates, geometric dimensions

[0088]

[0089] The integration of BIM technology and oblique photogrammetry technology has outstanding advantages in terms of traffic organization and safety risks. For example, based on the fusion model, the site engineering volume can be automatically extracted and the coordinate position and size information of temporary facilities can be obtained.

[0090] According to the degree level and weight of the evaluation index, the correlation value between the on-site facilities can be calculated, combined with the initial layout plan of the construction site ( Figure 7 ), determine the on-site traffic organization requirements, safety risk relationship values, and the level weights of each indicator, input them into the objective function for solution, and obtain the initial value of the objective function of the scheme as A. Please refer to Fig.10 , using python3.0 and other software to implement the ant colony algorithm for the initial layout plan of the construction site ( Figure 7 ) is used for optimization analysis. The site layout constraints must be followed and the relationship between the facilities on site must be combined to optimize the initial value of the objective function to obtain the optimal value of the objective function to be B. The result of B is the optimal result after continuous iterative optimization of each evaluation index.

[0091] The construction site layout based on BIM and oblique photogrammetry technology is a digital solution that realizes the three-dimensional reconstruction of the actual construction site, closely links with the actual site, effectively improves construction efficiency and quality, and reduces construction costs and risks.
