Description

Technical Field

[0001] This invention relates to the field of engineering management technology, specifically a BIM-based construction management method and system for building projects. Background Technology

[0002] BIM is a three-dimensional building model used for the information management of building projects. It is a digital representation of a building project, describing various information about the project and including various data and simulation information.

[0003] Construction management refers to the effective organization, coordination, supervision, and control of the entire process of a construction project, from planning and design to construction, completion and acceptance, and then to use and maintenance, to ensure that the project is completed smoothly according to the predetermined goals and standards. However, the construction process involves schedule planning, quality and safety control, and construction site management. Therefore, intelligent management of the construction process is necessary to ensure that construction is carried out on time, with quality, and safely, which has important theoretical and practical significance.

To this end, we now provide a BIM-based construction engineering management method and system. Summary of the Invention

[0010] The project acquisition terminal collects comprehensive information on building construction, obtains construction video information, and marks the duration of the collected construction video information.

[0011] Information on construction projects is collected through the project data collection terminal to obtain construction project information.

[0012] The process of obtaining standard construction frame drawings includes:

[0013] The extraction frequency is set according to the obtained video duration, and the obtained construction video information is frame extracted according to the set extraction frequency to obtain construction frame images;

[0014] The video duration is matched with the obtained construction frame images to obtain construction matching nodes;

[0015] The construction frame images are sorted according to the obtained construction matching nodes to obtain the construction frame sequence;

[0016] Based on the obtained construction matching nodes, samples are extracted from the obtained construction project information to obtain standard sample project diagrams and project matching nodes;

[0017] The obtained standard sample project graphs are sorted according to the obtained project matching nodes to obtain a standard sample graph sequence;

[0018] The obtained construction frame sequence is matched with the standard sample image sequence, and the successfully matched construction frame sequence is associated with the corresponding standard sample image sequence.

[0019] The input standard is set according to the obtained standard sample image sequence. The construction frame sequence is then standardized according to the obtained input standard to obtain the standardized construction frame image. The obtained standardized construction frame image is then marked as the input construction frame.

[0020] The process of obtaining construction drawings includes:

[0021] Based on the obtained standard construction frame diagram, a building feature extraction kernel is set, and the building feature extraction kernel includes the verification criteria and the number of kernels;

[0023] Based on the obtained building feature extraction kernel, a building feature extraction layer is set up, and the obtained building feature extraction kernel and the input construction frame are uploaded to the building feature extraction layer;

[0024] The obtained building feature extraction kernel is used to perform moving coverage extraction with the input construction frame to obtain the construction extraction map.

[0025] The process of extracting moving coverage by combining the obtained building feature kernel with the input construction frame includes:

[0026] Set the extraction start point based on the obtained input construction frame, upload the obtained building feature extraction kernel to the extraction start point of the input construction frame, and mark the corresponding area of ​​the building feature extraction kernel in the input construction frame as the extraction area;

[0027] The obtained building feature extraction kernel is convolved with the extraction area to obtain the extraction segment map;

[0028] Based on the obtained movement interval, the building feature extraction kernel at the starting point is moved in the input construction frame and inter-regional convolution is performed with the extraction area to obtain the extraction segment map until the building feature extraction kernel covers all areas in the input construction frame.

[0029] The extracted segmented images are combined based on the obtained input construction frames to obtain the construction extraction image.

[0030] The process of obtaining the sample extraction image includes:

[0031] Obtain the standard sample image sequence associated with the construction extraction drawing, perform standard verification on the obtained standard sample image sequence, and obtain the input sample image;

[0032] The obtained input sample image is uploaded to the building feature extraction layer and building feature extraction kernel for moving coverage extraction to obtain the sample extraction image.

[0033] The process of obtaining non-standard construction drawings includes:

[0034] Set up a BIM conversion space, upload the obtained construction extraction drawings and related sample extraction drawings to the BIM conversion space to obtain construction 3D drawings and sample 3D drawings;

[0035] Match the construction matching nodes of the construction 3D drawing with the project matching nodes of the sample 3D drawing to obtain the management time point;

[0036] At the management time point, the obtained construction 3D drawings and sample 3D drawings are marked with volume to obtain the construction volume and sample volume.

[0037] The difference volume is obtained based on the construction volume and the sample volume.

[0038] Set a volume difference threshold, compare the obtained volume difference with the volume difference threshold, and obtain standard construction drawings and abnormal construction drawings.

[0039] Based on the above-mentioned BIM-based building construction management system, the present invention also provides a BIM-based building construction management method, comprising the following steps:

[0040] Step 1: Collect comprehensive project information for building construction projects;

[0041] Step 2: Extract frames from the collected comprehensive project information to obtain construction frame sequences and standard sample image sequences. Set input standards based on the obtained standard sample image sequences. Perform standard verification on the construction frame sequences based on the obtained input standards to obtain standardized construction frame images. Mark the obtained standardized construction frame images as input construction frames.

[0042] Step 3: Set up the building feature extraction kernel based on the obtained standard construction frame image, set up the building feature extraction layer based on the obtained building feature extraction kernel, upload the obtained building feature extraction kernel and the input construction frame to the building feature extraction layer for moving coverage extraction, and obtain the construction extraction image;

[0043] Step 4: Standardize and verify the obtained standard sample drawing sequence and upload it to the building feature extraction layer for moving overlay extraction to obtain sample extraction drawings. Set up the BIM conversion space, upload the obtained construction extraction drawings and sample extraction drawings to the BIM conversion space to obtain construction 3D drawings and sample 3D drawings. Perform multiple volume comparisons on the obtained construction 3D drawings and sample 3D drawings to obtain abnormal construction drawings.

[0044] Compared with the prior art, the beneficial effects of the present invention are: by extracting frames from the collected construction video information to obtain a construction frame sequence, and by extracting samples from the construction project information to obtain a standard sample image sequence, the comparison of construction progress is carried out under the same conditions, thereby increasing the accuracy of the comparison.

[0045] By setting a building feature extraction layer on the input construction frame and performing moving coverage extraction, a construction extraction image is obtained, which greatly improves the feature extraction accuracy of the construction frame image and improves the clarity of the feature image.

[0046] Setting up a BIM conversion space allows for multiple volume comparisons between construction 3D drawings and sample 3D drawings at management time points to obtain abnormal construction drawings. By converting one-dimensional planar construction drawings into three-dimensional 3D construction drawings and comparing them with sample 3D drawings, it is beneficial to intuitively obtain construction progress, provide more accurate construction data, and greatly improve construction efficiency.

Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0048] Figure 1 This is a schematic diagram of the present invention. Detailed Implementation

[0049] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] like Figure 1 As shown, a BIM-based building construction management system includes a management center, which is connected to a data acquisition module, a project processing module, a status analysis module, and an intelligent control module.

[0051] The data acquisition module is used to collect comprehensive project information for building construction projects. This comprehensive project information includes construction video information and construction project information. The specific process includes:

[0052] Set up the engineering data acquisition terminal and the project data acquisition terminal;

[0053] The project acquisition terminal collects comprehensive information on building construction, obtains construction video information, and marks the duration of the collected construction video information.

[0054] Furthermore, the construction video information includes information on all buildings, construction personnel, and construction materials;

[0055] Information on construction projects is collected through the project data collection terminal to obtain construction project information;

[0056] Furthermore, the construction project information includes the construction project name, planned construction drawings, start and completion dates, and quality and safety requirements.

[0057] The project processing module is used to process the collected comprehensive project information to obtain the input construction frame. The specific process includes:

[0058] Set the extraction frequency based on the obtained video duration;

[0059] The obtained construction video information is frame-by-frame extracted according to the set extraction frequency to obtain construction frame images;

[0060] The video duration is matched with the obtained construction frame images to obtain construction matching nodes;

[0061] Furthermore, the obtained construction matching nodes are at the same time nodes as the extracted construction frame image frames;

[0062] The construction frame images are sorted according to the obtained construction matching nodes to obtain the construction frame sequence;

[0063] Based on the obtained construction matching nodes, samples are extracted from the obtained construction project information to obtain standard sample project diagrams and project matching nodes;

[0064] It should be further explained that, in the specific implementation process, the project matching node and the construction matching node are at the same time point, that is, according to the construction schedule, the standard construction drawings must be completed at the corresponding progress time node.

[0065] The obtained standard sample project graphs are sorted according to the obtained project matching nodes to obtain a standard sample graph sequence;

[0066] The obtained construction frame sequence is matched with the standard sample image sequence, and the successfully matched construction frame sequence is associated with the corresponding standard sample image sequence.

[0067] The input criteria are set based on the obtained standard sample image sequence, and the input criteria include image length, image width, and recognition channel;

[0068] It should be further explained that, in the specific implementation process, the image length and image width determine the pixels of the input image; the recognition channel represents the number of color channels in the input image, and each recognition channel represents a color;

[0069] The obtained construction frame sequence is standardized according to the input standard to obtain the standardized construction frame diagram, and the obtained standardized construction frame diagram is marked as the input construction frame.

[0070] The state analysis module is used to analyze the obtained input construction frames to obtain construction extraction diagrams. The specific process includes:

[0071] Based on the obtained standard construction frame diagram, a building feature extraction kernel is set. The building feature extraction kernel includes a verification standard and a number of kernels. The verification standard indicates the size of the building feature extraction kernel, including the standard length and standard width.

[0072] It should be further explained that, in the specific implementation process, the building feature extraction kernel is a matrix containing several elements, used to capture the local features of the input construction frame. Therefore, the building feature extraction kernel determines the different local features extracted from the input construction frame. In order to obtain a larger range of local features from the input construction frame, it is necessary to set a larger verification standard. In particular, the number of kernels represents the number of building feature extraction kernels, which determines the clarity of the extracted local features of the input construction frame.

[0073] Set the movement interval based on the obtained input construction frames and verification standards;

[0074] Based on the obtained building feature extraction kernel, a building feature extraction layer is set up, and the obtained building feature extraction kernel and the input construction frame are uploaded to the building feature extraction layer;

[0075] The obtained building feature extraction kernel is used to perform motion coverage extraction with the input construction frame to obtain the construction extraction map;

[0076] The process of extracting moving coverage from the building feature extraction kernel and the input construction frame includes:

[0077] Set the extraction start point based on the obtained input construction frame, upload the obtained building feature extraction kernel to the extraction start point of the input construction frame, and mark the corresponding area of ​​the building feature extraction kernel in the input construction frame as the extraction area;

[0078] The obtained building feature extraction kernel is subjected to interval convolution with the extraction area to obtain the extraction segment map. The interval convolution is to multiply the elements in the building feature extraction kernel with the pixel values ​​in the extraction area, and then add the obtained products to obtain the extraction segment map.

[0079] Based on the obtained moving interval, the building feature extraction kernel at the starting point is moved in the input construction frame to obtain the next extraction area. The obtained extraction area is then convolved with the building feature extraction kernel to obtain the extraction segment map. This process continues until the building feature extraction kernel is convolved with all extraction segment maps in the input construction frame.

[0080] The obtained extracted segmented images are combined based on the obtained input construction frames to obtain the construction extraction image.

[0081] The intelligent control module is used to perform three-dimensional transformation on the obtained construction extraction drawings to obtain three-dimensional construction drawings. Multiple volume comparisons are then performed on the obtained three-dimensional construction drawings to identify abnormal construction drawings. The specific process includes:

[0082] Obtain the standard sample image sequence associated with the construction extraction drawing, perform standard verification on the obtained standard sample image sequence, and obtain the input sample image;

[0083] The obtained input sample image is uploaded to the building feature extraction layer. The obtained building feature extraction kernel is then moved and covered with the input sample image to extract the sample image.

[0084] Set up a BIM conversion space, upload the obtained construction extraction drawings and related sample extraction drawings to the BIM conversion space to obtain construction 3D drawings and sample 3D drawings;

[0085] It should be further explained that, in the specific implementation process, BIM conversion space is to convert one-dimensional construction extraction drawings and sample extraction drawings into three-dimensional stereoscopic drawings using BIM software;

[0086] Match the construction matching nodes of the construction 3D drawing with the project matching nodes of the sample 3D drawing to obtain the management time point;

[0087] Furthermore, the matching involves acquiring identical construction matching nodes and project matching nodes;

[0088] At the management time point, multiple volume comparisons were performed on the obtained construction 3D drawings and sample 3D drawings to obtain abnormal construction drawings.

[0089] The process of performing multiple volume comparisons between the construction 3D drawing and the sample 3D drawing includes:

[0090] At the management time point, the obtained construction 3D drawings and sample 3D drawings are marked with volume to obtain the construction volume and sample volume.

[0091] The obtained construction volume is labeled as SG. i Let i represent the number of the construction 3D drawing, where i = 1, 2, 3, ..., u1, where u1 is a positive integer. The obtained sample volume is labeled YB. j j represents the number of the sample 3D image, where j = 1, 2, 3, ..., u2, and u2 is a positive integer;

[0092] Furthermore, the construction volume is the volume of the construction 3D drawing, and the sample volume is the volume of the sample 3D drawing.

[0093] At each management time point, the difference volume is obtained based on the acquired construction volume and sample volume. This difference volume is denoted as ΔV, where ΔV = SG. i -YB j ;

[0094] Set a volume difference threshold and mark the obtained volume difference threshold as V0;

[0095] The obtained difference volume is compared with the volume difference threshold to obtain standard construction drawings and abnormal construction drawings. The abnormal construction drawings include excess construction drawings and excess reduction construction drawings.

[0096] It should be further explained that, in the specific implementation process, in this embodiment, the volume difference threshold is set to 0. When ΔV = V0, it means that the construction volume and the sample volume are equal, that is, at the management time point, the construction progress has reached the planned construction progress; when ΔV > V0, it means that the construction volume is greater than the sample volume, that is, at the management time point, the construction progress exceeds the planned construction progress at the current time point, that is, the construction personnel have exceeded the construction plan at the planned time point; when ΔV < V0, it means that the construction volume is less than the sample volume, that is, at the management time point, the construction progress is behind the planned construction progress.

[0097] Upload the obtained non-standard construction drawings to the management center, obtain the name of the construction project corresponding to the non-standard construction drawings from the management center, record it as a non-standard project, and notify the person in charge of the non-standard project to conduct a safety inspection of the non-standard project.

[0098] Based on the above-mentioned BIM-based building construction management system, the present invention also provides a BIM-based building construction management method, comprising the following steps:

[0099] Step 1: Collect comprehensive project information for building construction projects;

[0100] Step 2: Extract frames from the collected comprehensive project information to obtain construction frame sequences and standard sample image sequences. Set input standards based on the obtained standard sample image sequences. Perform standard verification on the construction frame sequences based on the obtained input standards to obtain standardized construction frame images. Mark the obtained standardized construction frame images as input construction frames.

[0101] Step 3: Set up the building feature extraction kernel based on the obtained standard construction frame image, set up the building feature extraction layer based on the obtained building feature extraction kernel, upload the obtained building feature extraction kernel and the input construction frame to the building feature extraction layer for moving coverage extraction, and obtain the construction extraction image;

[0102] Step 4: Standardize and verify the obtained standard sample drawing sequence and upload it to the building feature extraction layer for moving overlay extraction to obtain sample extraction drawings. Set up the BIM conversion space, upload the obtained construction extraction drawings and sample extraction drawings to the BIM conversion space to obtain construction 3D drawings and sample 3D drawings.
