Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
It should be noted that, the calculation of the engineering quantity is implemented by using the calculation software, and because the expression of the component type and the component material attribute in the calculation software is different from the expression in the modeling software, there is a problem that the BIM model built by using the modeling software is directly applied to the calculation software and is not compatible. To solve this problem, it is often employed in the prior art to re-model in the scalar software, or to modify the BIM model again after it is imported into the scalar software, and so on. However, these approaches result in inefficient engineering volume calculations due to the re-construction of the model involved.
Based on the above, the embodiment of the invention provides a component matching method, after a building model is imported into calculation software, electronic equipment automatically performs matching conversion on the component attribute to be matched of a target primitive in the building model so as to obtain the target component attribute which can be directly used for engineering quantity calculation. For example, the expression of a window in the BIM model is a, and the expression that it can be used directly for engineering quantity calculation in the quantity calculation software is B, then a matching needs to be converted into B. Among them, a detailed description will be made below regarding a specific component matching method.
In accordance with an embodiment of the present invention, a component matching method embodiment is provided, it being noted that the steps shown in the flowchart of the figures may be performed in a computer system, such as a set of computer executable instructions, and, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order other than that shown or described herein.
In this embodiment, a component matching method is provided, which may be used in the above electronic device, such as a computer, a mobile phone, a tablet computer, etc., fig. 1 is a flowchart of a component matching method according to an embodiment of the present invention, and as shown in fig. 1, the flowchart includes the following steps:
S11, acquiring a target building model.
The target building model is a building model for engineering quantity calculation, and the target building model can be stored in the electronic equipment in advance or can be imported into the electronic equipment in real time when needed. The target building model may be a RVT or IFC format file. For example, the electronic device provides a file import interface at which to provide the user with a selection of loading the target building model for which calculation is desired.
And S12, analyzing the target building model to obtain the attribute of the member to be matched of the target primitive.
After the electronic equipment acquires the target building model, the target building model is analyzed, each graphic element in the target building model can be determined by a keyword identification method of the target building model, and then the component attribute of each graphic element is extracted to obtain the component attribute to be matched of each graphic element.
The electronic device may perform matching conversion on component attributes of a certain primitive, or may perform matching conversion on component attributes of certain primitives, or the like, and may specifically perform corresponding setting according to actual situations. The primitives that require matching transformations of component attributes are referred to as target primitives in this embodiment.
Specifically, the electronic equipment analyzes the target building model to obtain the attribute of the member to be matched of the target primitive in the target building model. The component attribute to be matched can be a component type, a component material attribute or a component name, etc., and the component material attribute is used for representing the material corresponding to the component type. For example, the target primitive 1 corresponds to the component types A1, A2, A3 and A4, and the component material attribute corresponding to each component type is B1, B2, B3 and B4; target primitive 2, corresponding component types are A5 and A6, component material properties corresponding to each component type are B5 and B6, and so on.
Optionally, in order to ensure the matching efficiency of the components, the electronic device may further analyze the floor information of the target building model, so as to perform batch processing of the target primitives on the same floor. Further alternatively, to ensure calculation of the subsequent engineering quantity, the electronic device may also analyze and obtain floor height and floor elevation information of each floor.
S13, inputting the member attribute to be matched into a preset matching model, and determining the target member attribute corresponding to the member attribute to be matched.
The target component attribute is attribute information directly used for engineering quantity calculation of the target building model.
After the electronic device obtains the member attribute to be matched of the target primitive in S12, the member attribute to be matched may be directly input into a preset matching model, and the target member attribute corresponding to the member attribute to be matched may be determined. Specifically, the input of the preset matching model is the attribute of the member to be matched, and the output is the matched attribute of the target member. That is, the input may be the component type and component material property of the target primitive, for example, the name, material (wall, beam, plate, column, door and window), and the output is a representation of the component type and component material property in the computing software. The specific model structure of the preset matching model is not limited at all, and can be set correspondingly according to actual situations.
The attribute information directly used for engineering quantity calculation of the target building model can be understood as attribute information which can be identified by the quantity software and does not need to be converted again. And utilizing the preset matching model to intelligently match and correlate the attribute of the member to be matched with the attribute of the target member, and determining the attribute of the target member corresponding to the attribute of the member to be matched.
It should be noted that, the attribute of the member to be matched, which is input to the preset matching model, may be the attribute of the member to be matched of all the primitives in the target building model, or may be the attribute of the member to be matched of one or some primitives selected by the user, etc., where the data input to the preset matching model is not limited, and the corresponding input setting may be specifically performed according to the requirement.
According to the component matching method provided by the embodiment, the target component attribute is matched with the component attribute to be matched by using the preset matching model, and the target component attribute is attribute information which can be directly used for subsequent engineering quantity calculation. The attribute of the member to be matched can be matched into attribute information which can be directly used for calculating the engineering quantity by using a preset matching model, so that the subsequent engineering quantity can be calculated by directly using a target building model, a complicated and time-consuming process of modeling is omitted, and the efficiency of calculating the subsequent engineering quantity is improved.
In this embodiment, a component matching method is provided, which may be used in the above electronic device, such as a computer, a mobile phone, a tablet computer, etc., fig. 2 is a flowchart of the component matching method according to an embodiment of the present invention, and as shown in fig. 2, the flowchart includes the following steps:
s21, acquiring a target building model.
Please refer to S11 in the embodiment shown in fig. 1 in detail, which is not described herein.
S22, analyzing the target building model to obtain the member attribute to be matched of the target primitive.
The attribute of the member to be matched of the target primitive can be sequentially performed on each primitive in the target building model, or can be performed on different floors.
For example, as shown in fig. 3, the electronic device analyzes the target building model to obtain floor information of each floor in the target building model, and then obtains the attribute of the member to be matched of the target primitive from the floor information. Fig. 3 is merely an example of floor information, and it is specifically analyzed or shown which information can be set according to actual requirements. The processing procedure of the preset matching model is described in detail in this embodiment.
In some optional implementations of this embodiment, the step S22 may include the following steps:
(1) And analyzing the target building model to obtain floor information in the target building model.
Wherein the floor information comprises member attributes to be matched of the primitives in each floor.
The electronic equipment can identify keywords of the target building model, determine each floor in the target building model, and extract floor information of each floor after determining each floor. The floor information may include each primitive in the floor and a component attribute of the primitive, and may further include an elevation, a height, and the like of the floor.
(2) And determining the attribute of the member to be matched of the target primitive based on the floor information in the target building model.
After floor information in the target building model is obtained, component attribute extraction is carried out on the target graphic element, and the component attribute to be matched of the target graphic element is determined.
For example, the electronic device may extract primitive information of each primitive in each floor information, where the primitive information includes a component type and a component material attribute corresponding to the primitive.
The rest of the detailed steps refer to S12 in the embodiment shown in fig. 1, and are not described herein.
S23, inputting the member attribute to be matched into a preset matching model, and determining the target member attribute corresponding to the member attribute to be matched.
The target component attribute is information directly used for engineering quantity calculation of the target building model.
Whether the data input into the preset matching model is floor information of all floors, or certain floor information, or the component attribute of certain graphic element, the preset matching model is internally processed according to the component attribute to be matched of each graphic element in each floor information.
For example, the floor information input to the preset matching model is floor information of a certain floor, and the floor information includes attributes of members to be matched of 4 primitives, so that the preset matching model can sequentially perform matching conversion on the attributes of the members to be matched. In other words, the preset matching model sequentially extracts the attributes of the members to be matched of each primitive in the floor information to obtain the target member attributes corresponding to the attributes of the members to be matched of each primitive.
Specifically, the step S23 includes the following steps:
s231, extracting field characteristics of the member attribute to be matched.
And after extracting the component attribute to be matched of the target primitive, the electronic equipment extracts the field characteristics of the component attribute to be matched. For example, the structure of the preset matching model employed in the present embodiment is shown in fig. 4. The model is used for intelligently identifying and relating attribute information of the user uploading model in the same language or cross language through a field matching technology, so that component attributes in the BIM model can be accurately and intelligently matched.
The model generates a prediction text by a field matching method, and mainly can be divided into two stages of feature extraction mapping and text matching, and the semantic space of the model is always similar although grammar structures and expression rules of different languages are different, so that a nonlinear mapping relation can be realized by utilizing a high-dimensional feature space of each text semantic.
For example, the preset matching model in the embodiment is established based on an ESIM algorithm, and the algorithm is matched with the advantages of high precision and short global legs, and the characteristic learning is performed by decomposing relevant fields into a word vector format, so that the rapid self-learning of the algorithm is facilitated. As shown in fig. 4, the component properties to be matched are component type and component material properties, for example, component type fields including a building model, wall, beam, plate, column, door and window, foundation, etc. are input; and cast-in-place concrete, precast concrete, masonry, brick, stone, glass, and other component material attribute fields.
After extracting the field characteristics of each member attribute to be matched, carrying out characteristic coding on the field characteristics. For example, LTSM feature extraction encoding is employed, i.e., a two-layer time-series neural network is invoked to learn and feature encode the input word vector and record feature concealment values according to the time series.
In some alternative implementations of this embodiment, if the target primitive is a fusion primitive, it may be necessary to perform hierarchical extraction. For RVT model components, such as a wall primitive, different components of multi-layer materials can be added in the structure, and then intelligent layered extraction of the installation materials of different components is needed. For example, as shown in fig. 5, for floor. A-floor slab surface layer-30, which is a combination of three layers of materials, it is necessary to extract field characteristics for each layer of material attribute.
Specifically, the step S232 may further include the following steps:
(1) Judging whether the component attribute to be matched has at least two component material attributes.
For example, as shown in fig. 5, the electronic device may determine for a field of a component material attribute of the target primitive. When at least two component material properties exist in the target graphic element, executing the step (2); otherwise, extracting field characteristics of the member attribute to be matched of the target primitive directly.
(2) And extracting field characteristics according to the component material properties.
And the electronic equipment extracts field characteristics and performs subsequent matching conversion on the material properties of each component of the target graphic element.
The field characteristics of the component attributes to be matched are extracted in a layered mode, namely, the field characteristics are extracted according to the different component material attributes, so that the field characteristics corresponding to the different component types and the component material attributes in the target graphic element are obtained, and the accuracy of the target component attributes corresponding to the target graphic element is improved.
S232, performing text prediction based on the extracted field characteristics to obtain the target component attribute.
Referring to fig. 4, after extracting the field features of the attribute of the member to be matched in S231, a step of local reasoning is performed, in which a attention model is mainly used, and the coded feature values are mainly subjected to differential calculation and analysis. The human attention is simulated mainly by constructing an attention machine model, high-value information is screened from a large amount of information, the high-value information is mainly used for assisting in receiving and screening out feature vectors output by LSTM, and similarity matrixes and differences of two short texts are further calculated.
Further, after the local reasoning, global reasoning is performed on the features, namely global information is integrated to perform reasoning and synthesis on the features. And extracting connection semantic information of the context through the LSTM, and performing five-fold combination on all subregions in the input features, namely splicing all segments of features by adopting maximum pooling and average pooling operation to form complete semantic association.
And finally, carrying out text speculation prediction on the basis of global reasoning to obtain the target component attribute corresponding to the component attribute to be matched of the target graphic element. Specifically, the obtained pooled semantic features are transmitted to a full-connection layer and received by a classification function softmax, meanwhile, an activation function sigmoid is called to realize nonlinear mapping and classification in a multidimensional space, and a final predicted value is displayed in a form of a matching field.
Wherein fig. 5 shows the corresponding expressions of the component types and the component material properties before and after matching. Wherein, the first column in the left frame of fig. 5 represents the floor, and the third column represents the material property of the component in the floor information; the first column in the right frame of fig. 5 shows the thickness of the floor, the second column shows the type of the matched member, and the third column shows the material property of the matched member.
After the electronic device sequentially performs the repetition processing of S231-S232 for each target primitive, the target component attribute corresponding to the component attribute to be matched of all the target primitives can be determined.
According to the component matching method, the target component attributes corresponding to the component attributes to be matched are obtained by extracting field features and predicting texts of the component attributes to be matched, namely, the accuracy of the obtained target component attributes is guaranteed by utilizing the high-precision prediction characteristics of deep learning, and reliable guarantee is provided for subsequent high-accuracy engineering quantity calculation.
