A building model construction method in the embodiment of the present application is described below with reference to fig. 2, where fig. 2 is a schematic flow chart of the building model construction method provided in the embodiment of the present application, and specifically includes the following steps:

step 201, acquiring an engineering drawing of a target building.

The target building may be a building, a garage, a house, and the like, and is not limited in this respect. The engineering drawings can be a plurality of engineering drawings, including external structures, internal structures, pipeline arrangement, electromechanical devices and the like, which are sufficient for constructing a complete building information model of the target building, and are not specifically limited herein.

Step 202, responding to the precision requirement of a target user for the building information model of the target building, and determining the depth grade of the building information model.

The accuracy requirement may represent an accuracy setting of a building information model by a target user, and the depth level represents a model accuracy of a building element in the target building. Generally, the depth levels can be classified as LOD100, LOD200, LOD300, LOD400, LOD500, and the precision of LOD100 to LOD500 increases in sequence. It will be appreciated that the LOD100 represents the solution design stage, i.e., it is provided with basic shapes, coarse sizes and shapes, including non-geometric data, only lines, areas, locations, etc.; the LOD200 represents the preliminary design stage, i.e., the approximate geometry, shape and orientation, that can reflect the approximate geometric characteristics of the object itself. The main appearance size can not be changed, the detail size can be adjusted, and the components comprise geometric size, material and product information (such as voltage, power and the like); LOD300 represents a construction drawing design stage, namely, main components of an object must be expressed accurately in geometry, the actual appearance of the object can be reflected, and it is guaranteed that misjudgment cannot be generated in construction simulation and collision inspection, a component should include geometric dimensions, materials, product information (such as voltage and power) and the like, and the information content of a model is consistent with the information content of a CAD drawing when the construction drawing design is finished and the like; the LOD400 represents a construction stage, namely a detailed model entity, finally determines the size of the model, and can process and manufacture components according to the model, wherein the components comprise geometric dimension, material and product information, and also need to be added with construction information of the model, including aspects of production, transportation, installation and the like; the LOD500 indicates as-built and, in addition to the final dimensions of the model, should include other information required for as-built submission including technical parameters of the process equipment, product specifications/operating manuals, maintenance and repair manuals, after-market information, etc.

LOD100-LOD200 are referred to as "ecological models" or "structural models" for energy consumption analysis or structural stress analysis at the design stage. LOD300-400 is referred to as a "process model" or "solution model" and is applied to the construction process simulation or solution demonstration aspects of the construction phase. The LOD500 is called as an operation and maintenance model, has the highest model grade, is applied to the operation and maintenance stage operation management aspect, and comprises all deeply designed contents, construction process information and various information meeting the operation requirements.

In one possible embodiment, the precision requirement may be a professional precision requirement, since the building field can be roughly divided into five specialties, namely a building specialty, a structural specialty, a drainage specialty, a heating and ventilation specialty, and an electrical specialty. Each professional engineering drawing is independent, so the information requirements corresponding to different depth grades are different according to different professions. The professional precision requirements can comprise any one or any combination of building precision requirements, structure precision requirements, drainage precision requirements, heating and ventilation precision requirements and electrical precision requirements. The amount of information required for each depth level for different specialties is exemplified below:

table one is a partial information category list of BIM models of building specialties LOD100 to LOD 500.

Table one

Table two is a list of partial information categories for BIM models of structure-specific LODs 100-500.

Table two

Table three is a list of information categories of BIM models of the water supply and sewerage specialties LOD100 to LOD 500.

Table four

Table five is a partial information category list of BIM models of the electrical specialties LOD100 to LOD 500.

Table five

From the above table, it is possible to determine the component depth level of each component of the above target building, which represents the amount of information required for modeling of the component element, according to professional accuracy requirements, i.e. the examples listed in the table.

In a possible embodiment, the precision requirement may be an application phase precision requirement, where the application phase precision requirement includes precision requirements of a design phase, a construction phase, and an operation and maintenance phase, for example, a target user may set the precision requirement of the operation and maintenance phase as: the depth level of the civil structure is required to be LOD100 and only models of layer 2 to layer 5 mechatronic devices and pipes are shown. And is not particularly limited herein. And determining an application stage depth level of the target building according to the application stage precision requirement, wherein the application stage depth level represents the amount of information required by modeling at the corresponding application stage for the target building.

In one possible embodiment, the accuracy requirement may further include an individualization requirement, and generally, after the depth level is determined, the depth level corresponds to a fixed related component, for example, the LOD100 includes a structural wall column, a structural plate, a building wall, an electromechanical device, a pipe, the LOD200 includes a structural wall column, a structural beam, a structural plate, a building wall, a door, a window, an electromechanical device, a pipe and a pipe fitting, the LOD300: including structure wall post, the structure roof beam, the structural slab, building wall, door and window, electromechanical device, pipeline and pipe fittings, no longer give unnecessary details here, it is visible, the component that the needs that different degree of depth levels correspond were modeled is preset, in this application, the target user can acquire the first component of predetermineeing that corresponds with above-mentioned component degree of depth level and predetermine the component with the second that the above-mentioned application stage degree of depth level corresponds, and carry out individualized screening, if remove the structure roof beam in the LOD300 and door and window and model. The first feedback data generated thereby may facilitate screening of a first target component from the first preset component, and the second feedback data generated thereby may facilitate screening of a second target component from the second preset component.

Therefore, the depth levels of all parts of the target building and the corresponding first target component and second target component can be automatically determined according to the requirements of the target user, and the accuracy and the efficiency of building model construction are greatly improved.

And 203, processing the engineering drawing according to the depth grade to generate a building information model according with the depth grade.

Wherein, the depth level may represent the depth levels of all the partial components, and an identification policy may be determined according to the depth level, the first feedback data and the second feedback data, that is, a first level of detail identification is performed on the first target component and the second target component with the depth level of LOD 100; performing a second level of detail identification on the first target component and the second target component having the depth level LOD 200; performing a third level of detail identification on the first target component and the second target component having the depth level LOD 300; performing a fourth level of detail identification on the first target component and the second target component with the depth level of LOD 400; and performing fifth level of detail recognition on the first target component and the second target component with the depth level of LOD500, wherein the recognition accuracy from the first level of detail recognition to the fifth level of detail recognition is increased in sequence.

The specific identification method may be an image identification technology, or may also be a search according to a component identifier, where different component structures have different component identifiers, and the component structure may be at least one of the following: rectangular columns, circular columns, i-beams, structural walls, building walls, electromechanical devices, pipes, panels, and the like, without limitation. In the embodiment of the present application, each component in the engineering drawing may correspond to a component identifier, and the component identifier may be at least one of the following: reference numerals, names, location marks, etc., which are not limited herein. Specifically, a component identification set in an engineering drawing can be obtained; and then, identifying and analyzing the target engineering drawing according to the component identification set to obtain component data required by building an information model. Therefore, the efficiency and the accuracy of engineering drawing identification can be improved.

For example, when the first detail level is identified, the structural plate only needs to identify the outline sideline of each layer of drawing, a plate with the default plate thickness as the preset value is generated, the electromechanical equipment is built according to the appearance shape, and the pipeline is built according to the same material and family type; during the second detail level identification, the structural plate identifies the outline according to the boundary of each plate on the engineering drawing, the plate with the default plate thickness as a preset value is generated according to the uniform elevation, the electromechanical equipment is built according to the appearance shape, and the pipeline accessory are built according to the same material and family type; and when the third detail level is identified, the structural plate identifies the outline according to the boundary of each plate on the engineering drawing, the structural plate is generated according to the elevation and the plate thickness on the drawing, the electromechanical equipment is established according to the detailed information of the drawing, the electromechanical equipment comprises an internal section of the electromechanical equipment, and the pipeline accessory are established according to different pipe diameter materials. The fourth level of detail identification and the fifth level of detail identification are not described in detail herein.

Therefore, the identification strategy can be determined, different identification modes are adopted in different areas, and the identification efficiency of the engineering drawing is improved.

Further, the identification range may be determined based on third feedback data of the target user, the third feedback data representing a range of the building information model. If the target user can select a modeling floor or a modeling range, the modeling range can be selected in a mode of selecting partitions through frames or only selecting an outer vertical surface range (selected in a mode of screening pull-down conditions), the background algorithm identifies a corresponding range image layer in a drawing through the corresponding pull-down conditions, an original image is copied, and other unnecessary image layers are deleted.

And finally, identifying the engineering drawing according to the identification strategy and the identification range so as to generate the building information model according with the depth grade.
