[0051] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0052] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0053] In the description of the present invention, "several" means more than one, "plurality" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of "first" and "second" in the description is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0054] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0055] In the description of the present invention, reference to terms such as "one embodiment," "some embodiments," "illustrative embodiments," "examples," "specific examples," or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the exemplary expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

[0056] In recent years, with the emergence of new technologies and materials in the construction industry and the increasing scale of public construction projects, curtain walls, as a key partner for high-rise and super-high-rise buildings, can present diverse shapes and variations under different visual perspectives, and have gradually become one of the main means of expressing designers' artistic inspiration. On-site curtain wall installation at high-rise construction sites primarily utilizes a "building block" construction method. Professional construction personnel use lifting equipment to hoist the curtain wall's supporting structure into place, install it layer by layer in situ at high altitude, and then install the curtain wall panels. As the primary load-bearing support system, component positioning is difficult, requires constant point verification, is time-consuming, and poses significant installation risks.

[0057] Nonlinear curved glass is particularly difficult to locate on-site. Existing technology involves refining the CAD drawings to find three easily located points on the curved glass surface: A, B, and C. The X, Y, and Z values ​​of A, B, and C are then calculated. These three points are then mapped onto the curved glass. A total station is then used to locate A, B, and C on-site. The curved glass is then hoisted to the appropriate location using a crane for installation. The existing technical solutions have the following disadvantages: Finding easily located points A, B, and C is difficult because the curved glass cannot be located, requiring only boundary points. Determining the X, Y, and Z values ​​of A, B, and C using traditional CAD is difficult, and locating the X, Y, and Z values ​​of A, B, and C on-site is tedious.

[0058] Based on this, the present invention provides a positioning method and device, and a storage medium for curtain wall construction. The positioning method for curtain wall construction constructs a main design model according to a pre-set structural construction drawing, scans the main body of the construction site to obtain a main point cloud model, and corrects the main design model according to the main point cloud model to obtain a main correction model. In the process of modeling according to the construction drawings, there will be certain errors. After the modeling is completed, the main design model is corrected by the main point cloud model so that the main design model can meet the accuracy requirements. A main design model that is more in line with the on-site main body can be obtained, which is helpful to improve the accuracy of creating a curtain wall keel design model; according to the main correction The positive model creates a curtain wall keel design model and extracts the control point data of the curtain wall keel design model to obtain the keel point data. The scanning robot installs the curtain wall keel according to the keel point data to obtain the curtain wall keel point cloud model. The curtain wall keel design model is corrected based on the curtain wall keel point cloud model to obtain the curtain wall keel correction model. By correcting the curtain wall keel design model using the curtain wall keel point cloud model, a curtain wall keel design model that is more consistent with the on-site curtain wall keel can be obtained, which helps to improve the accuracy of creating the curtain wall 3D model. The curtain wall keel 3D model is created based on the curtain wall keel correction model, and the control point data of the curtain wall 3D model is obtained to obtain the curtain wall point data. The curtain wall keel model is created through the main body correction model. The curtain wall keel model is created based on the curtain wall keel correction model, and the curtain wall point data is obtained from the curtain wall 3D model. By creating and reviewing the model multiple times, a high-precision three-dimensional model of the curtain wall is obtained, thereby achieving accurate positioning of the curtain wall. In particular, when the positioning method for curtain wall construction provided by the present invention is applied to curtain wall curved glass, a high-precision three-dimensional model of the curtain wall curved glass can be obtained, and the point position data of the control points on the three-dimensional model of the curtain wall curved glass can be easily extracted, thereby solving the problem of difficult positioning of the curtain wall curved glass during construction.

[0059] The embodiments of the present invention are further described below with reference to the accompanying drawings.

[0060] Reference Figure 1 An embodiment of the present invention provides a positioning method for curtain wall construction, which includes but is not limited to step S110, step S120, step S130, step S140, and step S150.

[0061] Step S110 : constructing a main body design model according to a preset structural construction drawing, and scanning the main body at the construction site to obtain a main body point cloud model.

[0062] In one embodiment, BIM software is used to create a 1:1 model based on the architectural and structural construction drawings provided by the design institute, and a design model of the main body of the building, structure, etc. is created. The shape and proportion of the main body design model are completely consistent with the construction blueprint.

[0063] In one embodiment, buildings and structures are distinguished by different colors to facilitate subsequent analysis and comparison.

[0064] In one embodiment, a 3D scanner is used to perform 3D scanning on the outlines of the buildings and structures at the construction site, thereby obtaining a high-precision point cloud model based on the point cloud data and completely consistent with the site.

[0065] Step S120 , correcting the main body design model according to the main body point cloud model to obtain a main body corrected model.

[0066] It should be noted that there will be certain errors in the process of creating a model based on construction drawings. After the scene is completed, the main design model will be corrected so that the created main design model can meet the accuracy requirements.

[0067] The main point cloud model is further processed to remove the interfering point cloud model data outside the main body, and the main point cloud correction model of the construction site area is obtained. The main design model is corrected according to the main point cloud correction model.

[0068] Due to the deviations between the main design model and the main construction site, these deviations will directly affect the deepening and positioning of the curtain wall frame vertical braces, and the installation of the curtain wall vertical braces directly affects the installation of the curtain wall nonlinear curved glass, thereby affecting the construction quality of the curtain wall nonlinear curved glass and material loss. Therefore, reviewing the deviations between the construction site dimensions and the drawing dimensions and correcting these deviations will improve the construction quality of the curtain wall nonlinear curved glass.

[0069] Step S130 , creating a curtain wall keel design model based on the main body correction model, extracting the control point data of the curtain wall keel design model, obtaining keel point data, and scanning the curtain wall keels installed by the robot based on the keel point data to obtain a curtain wall keel point cloud model.

[0071] In one embodiment, the curtain wall keel point cloud model is processed, for example, point cloud data splicing, point cloud model denoising, point cloud data smoothing, point cloud data interpolation, and point cloud data segmentation processing. The processed curtain wall point cloud model can better reflect the actual installed curtain wall keel.

[0072] Step S140 , correcting the curtain wall keel design model according to the curtain wall keel point cloud model to obtain a curtain wall keel corrected model.

[0073] In one embodiment, BIM software is used to create a curtain wall keel design model based on the main body correction model, and the curtain wall keel design model is deepened and optimized based on the curtain wall keel point cloud model to obtain a curtain wall keel correction model, thereby reducing the impact of the deviation of the main structure size at the construction site on the positioning of the curtain wall keel.

[0074] Step S150 , creating a three-dimensional curtain wall model based on the curtain wall keel correction model, and acquiring data of control points of the three-dimensional curtain wall model to obtain curtain wall point data.

[0076] Among them, point data includes: plane coordinate point data and high-level point data.

[0077] In one embodiment, extracting the position data of the curtain wall control points based on the curtain wall 3D model is equivalent to decomposing the curtain wall 3D model, and producing a processing and blanking list based on the curtain wall 3D model to perform processing and blanking of the curtain wall.

[0078] Reference Figure 2 Another embodiment of the present invention further provides a positioning method for curtain wall construction, which further includes but is not limited to: step S210 and step S220.

[0079] In step S210, the scanning robot obtains a curtain wall point cloud model by scanning the installed curtain wall according to the curtain wall point data.

[0080] In one embodiment, the free-range robot installs the curtain wall according to the curtain wall point data until the last row of curtain walls, and uses a three-dimensional scanner to scan the curtain wall installed on site to obtain a curtain wall point cloud model.

[0081] Step S220 , correcting the curtain wall three-dimensional model according to the curtain wall point cloud model to obtain an optimized curtain wall model.

[0082] In one embodiment, a model of the last row of curtain walls is obtained based on the curtain wall optimization model, and the point data of the control points of the last row of curtain walls are extracted based on the model of the last row of curtain walls. The robot installs the last row of curtain walls based on the point data of the control points of the last row of curtain walls, so as to eliminate all accumulated errors of the previously installed curtain walls when installing the last row of curtain walls.

[0083] In one embodiment, the curtain wall three-dimensional model is reviewed based on the curtain wall point cloud model to obtain the deviation area between the curtain wall point cloud model and the curtain wall three-dimensional model, the deviation area is marked to obtain deviation data, and the curtain wall three-dimensional model is corrected according to the deviation data to obtain the curtain wall optimization model.

[0084] Another embodiment of the present invention further provides a control method, such as Figure 3 As shown, Figure 3 yes Figure 1 FIG. 1 is a schematic diagram of another embodiment of a detailed process of step S110 in FIG. 1 , wherein step S110 includes but is not limited to:

[0094] Step S520 : performing a deviation review on the main body design model based on the first merged model to obtain a deviation area between the main body design model and the main body point cloud model.

[0095] In one implementation, the main design model and the main point cloud model are merged, and the main design model is comprehensively reviewed based on the merged model. The model features of the subject equipment model and the main point cloud model are obtained for merging, wherein the model features include: elevation of each floor, axis network, verticality of wall columns, degree of convexity and concavity of the facade, pre-embedded points of the structure, etc. By comparing and analyzing the model features of the subject equipment model and the main point cloud model, the deviation area between the main design model and the scanned point cloud model is found, and the area is clearly marked to determine the deviation report.
