Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0017] Please see Figure 1 , Figure 1 This is a flowchart illustrating a preferred embodiment of a method for automatically marking building functions and calculating area provided by the present invention. The method includes: S1, obtain the planning application drawings and planning verification floor plans for the building project; S2, respectively construct the layer index and spatial location index of the layered map in the planning application map and the planning verification plan; S3, based on the layer index and the spatial location index, map the building functions in the planning application drawing to the planning verification plan to obtain the automatic marking result of the building functions in the planning verification plan; S4. Construct an area calculation semantic library based on preset area calculation rules; S5. Based on the area calculation semantic library and the building function automatic labeling results of the planning verification plan, automatically match the corresponding area calculation rules, perform geometric operations, and output the area calculation results.

[0018] Specifically, this invention addresses the problems of low automation, low accuracy, and low efficiency in existing construction project planning verification and measurement processes. Combining the principles and processes of creating floor plans for construction project planning verification and measurement, it proposes an automatic marking and area calculation method for building functions. First, the planning application drawings and planning verification floor plans of the construction project are obtained. The planning application drawings are detailed construction project planning drawings provided by the construction unit to the administrative approval department, containing information such as the site plan and floor plans. The site plan determines the construction location (plane coordinates), and the floor plans determine the building function, structure, size, and other information for each floor. The planning verification floor plan is used after the construction project is completed to verify whether the construction has been carried out in accordance with the requirements of the application approval. It needs to accurately mark the functional areas of the building and accurately calculate the area to meet regulatory requirements. After obtaining the planning application drawings and planning verification floor plans, layer indices and spatial location indices are constructed for the floor plans in both the planning application drawings and the planning verification floor plans. Then, based on layer index and spatial location index, the building functions in the planning application drawings are mapped to the planning verification floor plan, resulting in automatic building function labeling results for the planning verification floor plan. Next, an area calculation semantic library is constructed according to preset area calculation rules. Finally, based on the constructed area calculation semantic library and the automatic building function labeling results from the planning verification floor plan, the corresponding area calculation rules are automatically matched, geometric operations are performed, and the building area calculation results are output.

[0019] This invention, based on automatic building function marking and area calculation, can automatically mark building functions and calculate area, reducing human judgment and marking, and achieving a high degree of automation. This effectively improves the accuracy and efficiency of building engineering planning verification measurements. It also enhances the calculation efficiency, accuracy, and data security of building area in building engineering planning condition verification measurements.

[0020] In a preferred embodiment, step S2, which involves constructing the layer index and spatial location index of the layered map in the planning application map and the planning verification plan, respectively, includes: S21, For the planning application drawing and the planning verification plan, construct the layer index based on the layer number or layer name of the building in the layer drawing; S22, for the planning application drawing and the planning verification plan, construct the layer space index using the coordinate values ​​of the smallest outer rectangle of the plan position of the layer in the layered drawing, and construct the building function space index using the coordinate values ​​of the geometric boundary of the building function, to obtain the spatial location index.

[0021] For details, please refer to Figure 2 , Figure 2 This is a schematic diagram of the layer index and spatial location index in the automatic marking and area calculation method for building functions provided by this invention. In this embodiment of the invention, for both the planning and approval drawings and the planning verification plan, layer indexes are constructed based on the floor numbers of the buildings in the layered drawings. For example, the layer index is either a floor number or a floor name, named after the floor number or floor name of the building in the layered drawing; for example, the layer index corresponding to the first floor of a building is 1. The spatial location index includes a layer spatial index and a building function spatial index. For both the planning and approval drawings and the planning verification plan, the layer spatial index is constructed based on the coordinate values ​​of the smallest bounding rectangle (top left, bottom left, top right, bottom right) of the planar position of each layer in the layered drawing. For example, the layer spatial index MBR is: TopLeft: X1, Y1, H1 TopRight: X2, Y2, H2 BottomLeft: X3, Y3, H3 BottomRight: X4, Y4, H4 A building function space index (COORS) is constructed using the coordinate values ​​of the building's functional geometric boundaries. For example, assuming the corresponding floor's planar position is used as a reference to establish an independent coordinate system, with the origin (0,0,0) at the bottom left corner (BottomLeft), north as the X-axis (BottomLeft-TopLeft), and east as the Y-axis (BottomLeft-BottomRight), the coordinate values ​​of the building's functional geometric boundaries are obtained counter-clockwise from the bottom left corner coordinates to form a coordinate set, which serves as the building function space index (COORS). Point0: X0, Y0, H0 Point 1: X1, Y1, H1 Point 2: X2, Y2, H2 Point 3: X3, Y3, H3 Point 4: X4, Y4, H4 … In another preferred embodiment, step S3, based on the layer index and the spatial location index, maps the building functions in the planning application drawing to the planning verification plan, obtaining the automatic building function labeling result of the planning verification plan, including: S31, based on the layer index and the spatial location index, perform spatial index matching calculation, and map the building functions in the planning application drawing to the planning verification plan according to the calculation result, so as to obtain the building function automatic marking result of the planning verification plan.

[0022] Specifically, in this embodiment of the invention, based on layer index and spatial location index, spatial index matching calculation is performed on the planning application drawing and the planning verification plan layer by layer, and the building functions in the planning application drawing are mapped to the planning verification plan according to the spatial index matching calculation results, so as to obtain the automatic marking result of building functions in the planning verification plan.

[0023] In another preferred embodiment, step S31 involves performing spatial index matching calculations based on the layer index and the spatial location index, and mapping the building functions in the planning application drawing to the planning verification plan according to the calculation results, thereby obtaining the automatic building function labeling results of the planning verification plan, including: S311, Based on the layer index and the layer space index, determine the layer correspondence between the planning application map and the planning verification plan; S312, based on the layer correspondence, traverse all building function space indices under the corresponding layer, and calculate the overlap ratio of the corresponding building functions between the planning application drawing and the planning verification plan; S313, when the overlap ratio is greater than a preset threshold, it is determined that the two building functions correspond, and the building functions in the planning application drawing are assigned to the building functions corresponding to the planning verification plan, so as to obtain the automatic marking result of the building functions in the planning verification plan.

[0024] Specifically, this embodiment of the invention determines the layer correspondence between the planning application drawing and the planning verification plan based on layer index and layer spatial index MBR. Then, according to the layer correspondence, it traverses all building function space indices under the corresponding layer, i.e., COORS1, COORS2, ..., and calculates the overlap ratio of corresponding building functions between the planning application drawing and the planning verification plan. For example, the formula for calculating the overlap ratio is: ; In the formula, , These represent the area of ​​the building functions in the layered diagrams of the planning application drawings and the planning verification floor plan, respectively.

[0025] When the calculated overlap ratio is greater than a preset threshold, the two building functions in the planning application drawing and the planning verification plan are determined to correspond. After successful building function matching, the building functions in the planning application drawing are assigned to the corresponding building functions in the planning verification plan, resulting in an automatic building function labeling result for the planning verification plan. For example, in this embodiment of the invention, the preset threshold is preferably 95%.

[0026] In another preferred embodiment, step S4 involves constructing an area calculation semantic library based on preset area calculation rules, including: S41, construct a third-order area calculation semantic library according to the preset area calculation rules; wherein, the third-order area calculation semantic library includes a first-order building type dimension, a second-order building function dimension, and a third-order calculation coefficient dimension in sequence; The first-order building type dimension is used to match the area calculation rules for the corresponding building type; The second-order building function dimension is used to determine the area calculation rules for building functions under the corresponding building types; The third-order calculation coefficient dimension is used to construct a Boolean matrix with the three elements of floor height, enclosure, and roof, and map the corresponding area calculation coefficients.

[0027] Specifically, this embodiment of the invention constructs a third-order area calculation semantic library based on preset area calculation rules. For example, the area calculation rules are shown in Table 1 below: Table 1. Rules for Calculating Building Area (Partial)

[0028] Based on the above area calculation rules, a third-order area calculation semantic library for building area calculation is constructed, and it can be freely expanded according to the area calculation rules. In this embodiment of the invention, the third-order area calculation semantic library sequentially includes a first-order building type dimension, a second-order building function dimension, and a third-order calculation coefficient dimension. The first-order building type dimension is used to match the area calculation rules for the corresponding building type, because different building types may have different calculation rules for the same building function space. Building types include residential, commercial, industrial, and others. The second-order building function dimension is used to determine the area calculation rules for the building function under the corresponding building type. For example, building functions include elevator shafts, pipe shafts, lobbies, halls, enclosed balconies, etc. The third-order calculation coefficient dimension is used to construct a Boolean matrix using the three elements of floor height, enclosure, and roof, mapping to obtain the corresponding area calculation coefficients. For example, the area coefficients are 1.0, 0.5, and 0, representing the calculation of full area, half area, and no area, respectively. It is mainly used to determine the calculable mathematical judgment, that is, to directly obtain the area calculation coefficient, multiply it by the geometric area to obtain the final building area.

[0029] For example, the Boolean matrix based on the three elements of floor height, enclosure, and roof yields the corresponding area coefficient as shown below: The mapping relationship is: f(story height, enclosure, roof) → {1.0, 0.5, 0} Floor height: H≥2.2m→1, H<2.2m→0 Enclosure: W=present → 1, W=absent → 0 Top cover: R=present → 1, R=absent → 0 JSON matrix: {"111": 1.0, "110": 0.5, "101": 0.0, "011": 0.0, ... } Assuming a building has a function, a floor height of 3m, an enclosure, and a roof, the key value for the query is determined to be "111" according to the above rules, and the area calculation coefficient is 1.0.

[0030] Based on the above-mentioned third-order area calculation semantic library, the calculation process is as follows: 1) Based on the building type, such as residential or commercial, obtain the corresponding JSON area calculation rules. For example, JSON["residential"] retrieves the area calculation rules for residential buildings, and the result is also a JSON semantic library. 2) Based on the building function, obtain the three elements of the building function: floor height, enclosure, and roof, and determine the area calculation rules for the building function under the corresponding building type; 3) Obtain the area calculation coefficient based on the three elements of floor height, enclosure, and roof, and calculate the building area.

[0031] Based on the above planning, the automatic marking results of the building functions in the layered plan of the floor plan are verified. The building functions of the building elements are automatically identified. By querying the area calculation semantic library, the function type of the building elements is automatically matched, the corresponding area calculation rules are called, geometric operations are performed, and the building area calculation results are output.

[0032] In yet another preferred embodiment, the method further includes: The calculated building area is automatically verified in multiple dimensions according to the preset verification operator rule library; wherein, each verification rule in the verification operator rule library corresponds to an independent single-function verification operator; the verification types include geometric consistency verification, logical rationality verification, standard compliance verification and data integrity verification, and each verification type includes multiple verification rules.

[0033] Specifically, after calculating the building area, this embodiment of the invention also performs multi-dimensional automatic verification of the calculated building area according to a preset verification operator rule library. Each verification rule in the verification operator rule library corresponds to an independent single-function verification operator to avoid confusion between verification operator functions, which would hinder maintenance. Verification types include geometric consistency verification, logical rationality verification, specification compliance verification, and data integrity verification. Each verification type includes multiple verification rules, as shown in Table 2 below: Table 2. Area Verification Rules (Partial)

[0034] According to the preset verification operator rule library, the present invention iterates through and executes each verification operator to automatically verify the calculated building area in multiple dimensions. After the verification is completed, the output error results are classified and corresponding modification guidelines are generated to improve the rectification efficiency of construction project planning verification measurement, avoid the omissions of manual inspection, and ensure the accuracy and efficiency of planning verification measurement.
