[0067] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments in the following description are only examples, and other obvious variations can be conceived by those skilled in the art.

[0068] Embodiment 1

[0069] Please refer to Figures 1-6 As shown, in the first aspect of the present invention, a method for providing feedback on cost consulting services based on BIM is provided, including:

[0070] S101. Take pictures of engineering drawing pictures, obtain the engineering drawing pictures, and perform denoising, enhancement, and segmentation on the engineering drawing pictures;

[0071] S102. Receive the engineering drawing pictures, and form a BIM visualization model according to the dimensions and structural components marked on the drawings. The structural components are divided into beams, columns, walls, foundations, and floors, and the beams, columns, walls, foundations, and floors are mapped to the corresponding floors according to the floors where they are located;

[0072] S103. Number the beams, columns, walls, foundations, and floors generated in the BIM visualization model, and number the floors;

[0073] S104. Generate a project implementation schedule according to the dimensions, costs, and man-hours marked on the beams, columns, walls, foundations, and floors, and transmit the implementation schedule to the database;

[0074] S105. Send the project implementation schedule to the Party A client, and catch up with the progress according to the opinions of the Party A client.

[0075] Those skilled in the art can understand that the drawing photographing module can quickly and accurately acquire and process engineering drawing pictures. By denoising, enhancing, and segmenting, it improves the clarity and readability of the drawings, providing high-quality input for subsequent steps. The acceptance module can automatically construct a BIM (Building Information Modeling) visualization model based on drawing annotations, greatly shortening the model creation time and reducing manual errors at the same time. Structural components (beams, columns, walls, foundations, and floors) can be mapped to the corresponding floors according to the floors where they are located, making the model more intuitive and easier to understand, and helping the project team better grasp the overall structure. The numbering module numbers the structural components and floors in the BIM model, which helps to standardize and regularize project management, improving the efficiency and accuracy of information transmission. The cost service module can generate an engineering implementation schedule based on the dimensions, costs, and man-hours of structural components, providing a more convenient cost consulting service for project budgeting and cost control.

[0076] The denoising of engineering drawing pictures specifically includes the following steps:

[0077] S201. Decompose the high-frequency information and low-frequency information in the engineering drawing picture;

[0078] S202. Perform local pixel grouping processing on the pixel points of the low-frequency information, use the unbiased estimation of the error to approximately represent the similarity between the local pixel block and the target pixel block, and obtain a sample set of similar local pixel blocks;

[0079] S203. Traverse each obtained sample set, and successively use the principal component analysis algorithm for denoising. By calculating the covariance matrix, obtain the orthogonal transformation matrix, and combine the eigenvalue matrix to remove the dimensions with a small amount of information in the sample set to obtain the reconstructed low-frequency component;

[0080] S204. Decompose the high-frequency information into overlapping blocks of the same size, calculate the Euclidean distance to construct groups of similar blocks, use singular value decomposition to learn the adaptive learning dictionary of each group, calculate the sparse coding through the split Bregman iteration algorithm combined with the convex optimization algorithm, and reconstruct the high-frequency component using the sparse coding and the adaptive learning dictionary;

[0081] S205. Aggregate the high-frequency component and the low-frequency component through wavelet inverse transform to obtain the denoised engineering drawing picture.

[0082] Those skilled in the art can understand that by decomposing the high-frequency and low-frequency information in the engineering drawing pictures, the details and overall structure in the pictures can be processed more precisely. High-frequency information usually contains detailed features such as edges and textures, while low-frequency information reflects the overall brightness and contrast of the pictures. This separation provides a basis for subsequent processing. Performing local pixel grouping processing on the pixel points of the low-frequency information helps reduce the computational amount and improve the processing efficiency. By using an unbiased estimate of the error to approximately represent the similarity between the local pixel block and the target pixel block, a sample set of similar local pixel blocks can be obtained. This method can enhance the local features of the picture and improve the visual effect of the picture. Using the principal component analysis (PCA) algorithm to denoise the sample set of the low-frequency information, by calculating the covariance matrix and the orthogonal transformation matrix, and combining the eigenvalue matrix to remove the dimensions containing little information, the reconstructed low-frequency component can be obtained. By performing wavelet inverse transformation to aggregate the high-frequency component and the low-frequency component, the denoised engineering drawing picture can be obtained. This method combines the advantages of high-frequency and low-frequency information, retaining both the overall structure of the picture and enhancing the detailed features of the picture.

[0084] S301. Perform adaptive histogram equalization processing on the engineering drawing picture;

[0085] S302. Determine the cumulative distribution function of the local area by calculating the gray histogram of the engineering drawing picture;

[0086] S303. Based on the cumulative distribution function, adaptively adjust the gray mapping relationship of the local area to obtain the enhanced image of the engineering drawing picture.

[0087] Segmenting the engineering drawing picture specifically includes the following steps:

[0088] S401. Segment the enhanced image of the engineering drawing picture into multiple superpixels through the superpixel segmentation algorithm;

[0089] S402. Determine the similarity matrix between superpixels as the edge weights of the undirected graph, and construct the superpixel graph cut undirected graph;

[0090] S403. Combine the preset probability distribution of the infrastructure engineering area, and solve the global optimal solution of the superpixel graph cut undirected graph through the maximum flow minimum cut algorithm;

[0091] S404. Obtain the segmentation result of the infrastructure engineering area to get the engineering drawing picture.

[0092] Numbering the beams, columns, walls, foundations, and floors generated in the BIM visualization model, and numbering the floors specifically includes the following steps:

[0093] S501. Number the floors generated by the BIM visualization model as C i , where i represents the floor;

[0094] S502. Number the beams generated by the BIM visualization model as where i is the subscript of C on the floor where it is located i ;

[0095] S503. Number the columns generated by the BIM visualization model as where i is the subscript of C on the floor where it is located i ;

[0096] S504. Number the walls generated by the BIM visualization model as where i is the subscript of C on the floor where it is located i ;

[0097] S505. Number the foundations generated by the BIM visualization model as D j ;

[0098] S506. Number the floor slabs generated by the BIM visualization model as where i is the subscript of C on the floor where it is located i .
