Through BIM technology, functions such as dynamic construction process simulation and real-time progress tracking can be realized, supporting project planning and schedule control.

[0003] The current method for simulating construction progress using BIM models mainly involves coding to bind progress information to the physical model; progress information is then entered by project managers, and the visibility of the physical model is determined based on this information. However, this method cannot meet the timeliness requirements of project management, nor can it synchronize the actual project progress with the displayed progress; furthermore, it suffers from insufficient accuracy in displaying the project progress. Summary of the Invention

Therefore, using the project progress display method provided in this application embodiment, the progress view of the construction site can be combined with BIM in real time, enabling synchronous display of project progress using the BIM model; it has good timeliness and high display accuracy.

[0007] Optionally, in this embodiment of the application, displaying and / or hiding the initial BIM model of the target project based on the target buildings in the majority of the target project site views to obtain the target project BIM model includes: dividing the initial BIM model of the target project into BIM voxels; wherein, a BIM voxel represents the smallest unit of the target project progress display; and displaying and / or hiding the BIM voxels based on the target buildings in the target project site views to obtain the target project BIM model.

[0008] In the above implementation process, after the initial BIM model of the target project is divided into BIM voxels, the BIM voxels are displayed and / or hidden according to the target buildings in the site view of the target project to obtain the target project BIM model. Therefore, the project progress display method provided in this application, by dividing the BIM model into the smallest granular units capable of displaying project progress, namely BIM voxels, and then displaying and / or hiding them, achieves the acquisition of the target project BIM model, enabling the display of the target project with high accuracy.

[0009] Optionally, in this embodiment of the application, before segmenting the initial BIM model of the target project into BIM voxels, the method further includes: preprocessing the initial BIM model of the target project to obtain a preprocessed initial BIM model of the target project; wherein, the preprocessing includes translating, rotating, scaling and / or perspective of the initial BIM model of the target project.

[0010] In the above implementation process, the project progress display method provided in this application preprocesses the initial BIM model of the target project before dividing it into BM voxels, and performs operations such as translation, rotation, scaling and / or perspective on the initial BIM model of the target project.

[0012] In the above implementation process, the image acquisition device is configured to acquire site views of the target project from multiple field angles; a target view can be obtained based on the site views of the multiple target projects, and then the BIM voxels are displayed and / or hidden based on the target buildings in the target view to obtain the BIM model of the target project; that is, the project progress display method provided in this application embodiment accurately combines multiple field angles of the construction site with the BIM model, and can realize the synchronous display of the construction site through the BIM model.

[0013] Optionally, in this embodiment, the comparison line includes the outer contour line and inner boundary line of the target building in the target view; displaying and / or hiding BIM voxels based on the target building in the target view to obtain the target project BIM model includes: extracting the outer contour line and inner boundary line of the target building in the target view; hiding BIM voxels that extend beyond the outer contour line; obtaining all connected components based on the outer contour line and inner boundary line; and displaying BIM voxels that overlap with the connected components to obtain the target project BIM model.

[0014] In the above implementation process, the project progress display method provided in this application compares the BIM model with the building image, showing or hiding model voxels to match the BIM model with the building image. The visibility of each model voxel within the outline is continuously adjusted until the boundary lines match, achieving high-precision display of the project progress from the BIM model through continuous adjustments.

[0015] Optionally, in this embodiment of the application, determining whether the comparison lines of the target building in the BIM model of the target project and the site view of the target project are consistent includes: determining whether the inner boundary line of the target building in the target view is consistent with the inner boundary line of the BIM voxel; if the inner boundary line of the target building in the target view is consistent with the inner boundary line of the BIM voxel, then it is determined that the adjustment of the BIM voxel is completed.

[0016] In the above implementation process, the project progress display method provided in this application, after displaying and / or hiding BIM voxels through the target building in the target view to obtain the target project BIM model, further determines whether the inner boundary line of the target building in the target view is consistent with the inner boundary line of the BIM voxel. If they are consistent, the adjustment can be considered complete, and the project can be rendered and displayed based on the target BIM model.

[0017] Optionally, in this embodiment of the application, before displaying and / or hiding the initial BIM model of the target project based on the target building in the site view of the target project, the method further includes: acquiring spatial information of multiple image acquisition devices; wherein, the spatial information includes three-dimensional coordinates, orientation, focal length, field of view and relative position with the target building; and establishing the initial BIM model of the target project in the project progress display system based on the spatial information.

[0018] In the above implementation process, the engineering progress display method provided in this application integrates the on-site information such as the coordinate position, focal length, and field of view of the image acquisition device into the construction of the BIM model; it can set the perspective, scaling, rotation, and translation parameters of the BIM model according to the coordinate position, focal length, and field of view of the image acquisition device; it achieves the high consistency between the BIM model and the on-site field of view, so that the image rendered by the final BIM model on the display screen is consistent with the position, size, and orientation of the extracted building image.

[0019] Optionally, in this embodiment of the application, the project progress display method further includes: if it is determined that the comparison lines of the target building in the target project BIM model and the target project site view are inconsistent, then the target building in the target project BIM model and the target project site view are adjusted until the comparison lines are consistent.

[0020] In the above implementation process, the project progress display method provided in this application embodiment needs to make the boundary lines of each face inside the building BIM model consistent with the boundary lines between each face inside the building, and continuously adjust the visibility of each model voxel within the outline until the boundary lines match, so as to finally achieve accurate display of project progress.

[0033] The technical solutions of the embodiments of this application will now be described with reference to the accompanying drawings. For example, the flowcharts and block diagrams in the drawings illustrate the architecture, functions, and operations of possible implementations of systems, methods, and computer program products according to various embodiments of the present invention.

It should also be noted that each block in the block diagram and / or flowchart, and combinations of blocks in the block diagram and / or flowchart, can be implemented using a dedicated hardware-based system that performs the specified function or action, or can be implemented using a combination of dedicated hardware and computer instructions. In addition, the functional modules in the various embodiments of the present invention may be integrated together to form an independent part, or each module may exist separately, or two or more modules may be integrated to form an independent part.

[0034] During the research process, the applicant found that the current method for using BIM models to simulate project construction progress mainly involves coding to bind progress information to the entity model; progress information is then entered by project management personnel, and the visibility of the entity model is determined based on this information. Due to the diversity of model entity divisions and the lag in progress information entry, using BIM models to represent the project's visual progress cannot meet project management requirements. Furthermore, the accuracy of the target's progress display is insufficient, and the user experience needs improvement.

[0035] Based on this, and with the continuous development of image recognition technology and BIM technology, the project progress display method provided in this application combines image recognition technology and BIM technology to further improve the accuracy of project progress display and overcome the problem of information transmission lag in existing technical solutions.

[0036] Please refer to Figure 1 , Figure 1 A flowchart illustrating a method for displaying project progress provided in this application embodiment; the method includes the following steps:

[0037] Step S100: The image acquisition device acquires multiple site views of the target project.

[0038] In step S100 above, the image acquisition device acquires multiple site views of the target project; wherein, the site view of the target project refers to the construction site, and the site view of the target project can refer to the site progress images of the target building in various directions or at different levels of the construction site.

[0039] For example, the image acquisition device can be a camera, video camera, or other devices with photographic capabilities; various types of image acquisition devices can be used in the embodiments of this application, such as a camera device fixed at the construction site or a drone that can move autonomously. It should be clearly stated that the types of image acquisition devices listed in this application should not be construed as limiting the scope of protection of the engineering progress display method provided in the embodiments of this application.

[0040] Step S101: Based on the target building in the site view of the target project, display and / or hide the initial BIM model of the target project to obtain the BIM model of the target project.

[0041] In step S101 above, after obtaining the site view of the target project, the target building in each site view is obtained; the initial BIM model is adjusted according to the target building in the site view of the target project; the adjustment method includes showing and hiding, and after adjusting the initial BIM model, the BIM model of the target project is obtained.

[0042] Step S102: Determine whether the alignment lines of the target building in the BIM model of the target project and the site view of the target project are consistent.

[0043] Step S103: If the comparison lines of the target building in the target project BIM model and the target project site view are consistent, the target project BIM model after the comparison is completed will be displayed.

[0044] In steps S102-S103 above, for the adjusted BIM model of the target project, it is necessary to further determine whether the BIM model of the target project meets the display requirements. Specifically, it is determined whether the comparison lines of the target project BIM model and the target building in the site view of the target project are consistent. If the comparison lines are consistent, the target project BIM model after the comparison is completed will be displayed.

[0045] pass Figure 1As can be seen, the project progress display method provided in this application acquires a site view of the target project using an image acquisition device; the initial BIM model is adjusted based on the site view of the target project until the comparison lines of the target project view and the BIM model are consistent, then the comparison ends, and the BIM model of the target project after the comparison is completed is displayed. Therefore, using the project progress display method provided in this application, the progress view of the construction site can be combined with BIM in real time, enabling synchronous display of project progress using the BIM model; it has good timeliness and high display accuracy.

[0046] Please refer to the following: Figure 2 , Figure 2 A first flowchart for obtaining the target project BIM model provided in this application embodiment; in an optional embodiment, the process of displaying and / or hiding the initial BIM model of the target project based on the target buildings in a majority of the target project site views to obtain the target project BIM model includes the following steps:

[0047] Step S200: Divide the initial BIM model of the target project into BIM voxels.

[0048] In step S200 above, the initial BIM model of the target project is divided into BIM voxels. It should be noted that a BIM voxel can be understood as the smallest particle that can realize the visual progress display of the project (such as foundation structure, column structure, wall structure, doors and windows, etc.). In this embodiment of the application, the project progress is accurately displayed by adjusting the smallest particle.

[0049] Optionally, after dividing the initial BIM model of the target project into BIM voxels, the divided voxels are further stored in the project progress display system for subsequent use.

[0050] Step S201: Show and / or hide BIM voxels based on the target building in the target project site view to obtain the target project BIM model.

[0051] In step S201 above, after the initial BIM model of the target project is divided into BIM voxels, the BIM voxels are further displayed and / or hidden according to the target building in the site view of the target project to obtain the BIM model of the target project.

[0052] pass Figure 2As can be seen, after dividing the initial BIM model of the target project into BIM voxels, the BIM voxels are displayed and / or hidden according to the target buildings in the site view of the target project to obtain the target project BIM model. Therefore, the project progress display method provided in this application, by dividing the BIM model into the smallest granular units capable of displaying project progress, namely BIM voxels, and then performing display and / or hiding operations, achieves the acquisition of the target project BIM model, enabling the display of the target project with high accuracy.

[0053] In an optional implementation, before segmenting the initial BIM model of the target project into BIM voxels, the project progress display method further preprocesses the initial BIM model of the target project: preprocessing the initial BIM model of the target project to obtain a preprocessed initial BIM model of the target project. For example, the preprocessing of the initial BIM model generally involves aligning the BIM model; specifically, aligning the BIM model can involve translating, rotating, scaling, and / or perspective manipulation of the initial BIM model of the target project.

[0054] Therefore, the project progress display method provided in this application preprocesses the initial BIM model of the target project before dividing it into BM voxels, and performs operations such as translation, rotation, scaling and / or perspective on the initial BIM model of the target project. Using the preprocessed initial BIM model of the target project can improve the accuracy of project progress display.

[0055] Please refer to Figure 3 , Figure 3 A second flowchart for acquiring the target project BIM model provided in this application embodiment; in an optional embodiment of this application, the image acquisition device is configured to acquire site views of the target project from multiple field angles.

[0056] Optionally, cameras can be installed around the construction site to identify and extract the building from the images captured by the cameras. At least three cameras should be installed, positioned in three directions: front view, left view, and top view of the construction work surface of the building to be monitored. Importantly, at least one camera should be pointed directly at the construction work surface of the target building. Furthermore, the camera's coordinates, focal length, and field of view are stored in a database within the processing system.

[0057] In the aforementioned solution, BIM voxels are displayed and / or hidden based on the target building in the site view of the target project to obtain the BIM model of the target project, such as... Figure 3 As shown, the following steps may be included:

[0058] Step S300: Obtain multiple site views of the target project corresponding to multiple field of view angles.

[0059] In step S300 above, multiple target engineering site views corresponding to multiple field of view angles are acquired. It is understood that the image acquisition device in the engineering progress display method provided in this application embodiment can be set in front of the construction work surface, and the number of image acquisition devices and their installation positions can be adaptively adjusted.

[0060] Step S301: Based on the target management items of the target project, perform weighted discrimination on multiple site views of the target project to obtain the target view.

[0061] In step S301 above, multiple site views of the target project are weighted and judged according to the target management items of the target project to obtain the target view. It can be understood that the image acquisition device acquires multiple site views of the target project, but the images used for BIM model display are filtered or weighted.

[0062] To better understand the necessity of weighted judgment, an example is given to illustrate the process of obtaining the target view. For example, in the case of a building, the building's working surface is its cross-section, and the key element for project schedule management is its height. Therefore, the image acquisition device directly facing the building has a higher weight because its image directly reflects the building's height. The image acquisition device directly facing the building's working surface has a relatively lower weight because its image reflects a more accurate progress at the building's working surface, serving as a supplement to the building's project schedule. In other words, the weight allocation in the target view generation process in this embodiment is related to the building's working surface and the key elements of project schedule management.

[0063] It should be noted that a target view can include one target view or multiple target views, and the number of target views can be adjusted according to actual needs.

[0064] Step S302: Obtain the target building in the target view.

[0065] Step S303: Show and / or hide BIM voxels based on the target building in the target view to obtain the target project BIM model.

[0066] In steps S302-S303 above, after obtaining the target view in step S301, the target building in the target view is extracted; further, the BIM voxels are displayed and / or hidden according to the target building in the target view to obtain the target project BIM model.

[0067] pass Figure 3It is understood that the image acquisition device is configured to acquire site views of the target project from multiple field angles; a target view can be obtained based on the site views of multiple target projects, and then BIM voxels can be displayed and / or hidden based on the target buildings in the target view to obtain the BIM model of the target project; that is, the project progress display method provided in this application embodiment accurately combines multiple field angles of the construction site with the BIM model, and can realize the synchronous display of the construction site through the BIM model.

[0068] Please refer to Figure 4 , Figure 4 A third flowchart for obtaining the target project BIM model provided in this application embodiment; in an optional embodiment of this application, the comparison lines include the outer contour line and inner boundary line of the target building in the target view; BIM voxels are displayed and / or hidden according to the target building in the target view to obtain the target project BIM model, such as Figure 4 As shown, it includes the following steps:

[0069] Step S400: Extract the outer contour lines and inner boundary lines of the target building in the target view.

[0070] In step S400 above, the outer contour line and inner boundary line of the target building in the target view are extracted; it can be understood that there is only one outer contour line, and it is a closed curve; while there can be multiple inner boundary lines, all of which are located inside the outer contour line.

[0071] Step S401: Hide the BIM voxels that extend beyond the outer contour line.

[0072] Step S402: Obtain all connected components based on the outer contour line and the inner boundary line.

[0073] Step S403: Display the BIM voxels that overlap with the connected domains to obtain the BIM model of the target project.

[0074] In steps S401-S403 above, after obtaining the outer contour line and inner boundary line, the portion of the BIM voxel that extends beyond the outer contour line is hidden. Further, all connected components are obtained based on the outer contour line and inner boundary line, and BIM voxels that overlap with the connected components are displayed to obtain the target project BIM model. Optionally, the display and hiding of the outer contour line and inner boundary line can be performed using a deep learning algorithm, thereby improving the display accuracy.

[0075] The display and hiding of the model can be understood as follows: First, based on the outer contour of the extracted building image, hide all BIM model voxels outside the outer contour; then, based on the inner boundary line of the extracted building image, continuously adjust the visibility of the remaining voxels until the inner boundary line of the BIM model matches the inner boundary line of the building image.

[0076] pass Figure 4 As can be seen, the project progress display method provided in this application compares the BIM model with the building image, showing or hiding model voxels to match the BIM model with the building image. The visibility of each model voxel within the outline is continuously adjusted until the boundary lines match, achieving high-precision display of the project progress using the BIM model through continuous adjustments.

[0077] Please refer to Figure 5 , Figure 5 This application provides a flowchart for determining the completion of BIM voxel adjustment in an embodiment of the present application; in an optional embodiment of the present application, it determines whether the alignment lines of the target building in the target project BIM model and the target project site view are consistent, such as... Figure 5 As shown, it includes the following steps:

[0078] Step S500: Determine whether the inner boundary line of the target building in the target view is consistent with the inner boundary line of the BIM voxel.

[0079] In step S500 above, after adjusting the visibility of the target project BIM model based on steps S400-S403 in the aforementioned scheme, it is determined whether the inner boundary line of the target building in the target view is consistent with the inner boundary line of the BIM voxel.

[0080] Step S501: If the inner boundary line of the target building in the target view is consistent with the inner boundary line of the BIM voxel, then the adjustment of the BIM voxel is determined to be complete.

[0081] In step S501 above, if it is determined that the inner boundary line of the target building in the target view is consistent with the inner boundary line of the BIM voxel, then the adjustment of the BIM voxel is completed.

[0082] pass Figure 5 As can be seen, the engineering progress display method provided in this application, after displaying and / or hiding BIM voxels by the target building in the target view to obtain the target engineering BIM model, further determines whether the inner boundary line of the target building in the target view is consistent with the inner boundary line of the BIM voxel. If they are consistent, the adjustment can be considered complete, and the model can be rendered and displayed based on the target BIM model.

[0083] Please refer to Figure 6 , Figure 6 The flowchart for obtaining the initial BIM model of the target project provided in this application embodiment; before displaying and / or hiding the initial BIM model of the target project based on the target buildings in the site view of the target project, the method for displaying the progress of the target project further includes:

[0084] Step S600: Obtain spatial information of multiple image acquisition devices.

[0085] In step S600 above, spatial information of multiple image acquisition devices is acquired; wherein, spatial information may include three-dimensional coordinates, orientation, focal length, field of view, and relative position to the target building, etc.

[0086] Step S601: Establish the initial BIM model of the target project in the project progress display system based on the spatial information.

[0087] In step S601 above, an initial BIM model of the target project is established in the project progress display system based on spatial information. For example, the perspective, scaling, rotation, and translation parameters of the BIM model are set according to the coordinate position, focal length, and field of view of the image acquisition device. This is equivalent to establishing a viewpoint in the BIM model space. This viewpoint maintains consistency with the spatial relationship between the BIM model and the spatial relationship between the image acquisition device and the building, thereby ensuring that the image rendered on the BIM model on the display screen maintains consistency with the position, size, and orientation of the extracted building image.

[0088] according to Figure 6 As can be seen, the engineering progress display method provided in this application integrates the coordinate position, focal length, and field of view of the image acquisition device into the construction of the BIM model; it can set the perspective, scaling, rotation, and translation parameters of the BIM model according to the coordinate position, focal length, and field of view of the image acquisition device; it achieves high consistency between the BIM model and the field of view, so that the image rendered by the final BIM model on the display screen is consistent with the position, size, and orientation of the extracted building image.

[0089] In an optional embodiment, the project progress display method further includes: if it is determined that the alignment lines of the target building in the target project BIM model and the target project site view are inconsistent, then adjusting the target building in the target project BIM model and the target project site view until the alignment lines are consistent.

[0090] Therefore, the project progress display method provided in this application requires that the boundary lines of each surface inside the building BIM model be consistent with the boundary lines between each surface inside the building, and the visibility of each model voxel within the outline is continuously adjusted until the boundary lines match, so as to finally achieve accurate display of project progress.

The visibility adjustment module 110 displays and / or hides the BIM voxels based on the target buildings in the target project site views to obtain the target project BIM model.

[0096] In an optional embodiment, the project progress display system 100 further includes a preprocessing module 130; before the voxel segmentation module 111 segments the initial BIM model of the target project into BIM voxels, the preprocessing module 130 preprocesses the initial BIM model of the target project to obtain a preprocessed initial BIM model of the target project; wherein, the preprocessing includes translating, rotating, scaling and / or perspective of the initial BIM model of the target project.

[0097] In an optional embodiment, the visibility adjustment module 110 further includes a target view acquisition module 112. The image acquisition device is configured to acquire target project site views from multiple view angles.
