It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the application described herein may be used.

It should be noted that the embodiments and features of the embodiments in the present application may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
According to an embodiment of the present application, there is provided a method for displaying a BIM model, as shown in fig. 1, the method includes the following steps:
s101, the server side obtains current space position information or building drawing information sent by the AR equipment.
The server provides the BIM stored with the user's desire to show to AR equipment, the AR equipment refers to the AR equipment such as Microsoft HoloLens and MagicLeap, and system software of the equipment comprises basic voice instruction and information input and processing functions of gesture operation and basic space position calculation and recognition functions. In addition to the general AR device function, the AR device in this embodiment further embeds a client corresponding to the server. Thus, data interaction can be carried out between the client and the server through the client installed in the AR device.
The service end acquires the current spatial position information or the construction drawing information so as to match a BIM (building information modeling) corresponding to the current spatial position information or the construction drawing information from the database according to the current spatial position information or the construction drawing information. The current spatial position information is the spatial position information where the AR device is currently located, namely the visible visual field range of the user wearing the AR device. The construction drawing information is information contained in the construction drawing lock corresponding to the BIM model to be displayed. The current spatial position information or the construction drawing information can be obtained by the AR device through spatial position calculation and image recognition functions.
And S102, the service end matches a BIM corresponding to the current spatial position information or the building drawing information from all BIM models according to the current spatial position information or the building drawing information.
All BIM models are stored in a database corresponding to the server side, and all BIM models refer to all BIM models corresponding to the whole building structure. Wherein the entire building structure is referred to in this embodiment as a building or a group of buildings. The specific storage mode of the BIM model in the database is that each BIM model is correspondingly stored with a corresponding unique identity, wherein the identity is configured by self-definition during storage. Each BIM model is stored in the database in the form of BIM data, and the BIM data comprises geometric data and non-geometric data corresponding to the BIM model. Non-geometric data includes attribute data, modeling related other data, and the like.
The principle that the server matches the corresponding BIM model according to the current spatial position information or the construction drawing information is that matching is performed according to an Artificial Intelligence (AI) algorithm. Before matching, training of the algorithm model is required according to the sample to obtain a matched algorithm model, the input of the algorithm model is the spatial position information or the construction drawing information of the AR equipment, and the output of the algorithm model is the unique identity corresponding to the BIM model. It should be noted that, when a set of spatial location information or a set of construction drawing information is input, the unique identifier that can be obtained is one or one set, because a set of spatial location information or a set of construction drawing information may correspond to multiple BIM models, and each BIM has a unique identifier. Therefore, the acquired current spatial position information or the acquired construction drawing information is input into the matched algorithm model to obtain the unique identity of the BIM corresponding to the current spatial position information or the construction drawing information, and then the BIM data corresponding to the corresponding BIM can be searched in the database according to the unique identity.
The matching of the BIM model through AI can improve the matching efficiency.
And S103, sending the BIM corresponding to the current spatial position information or the construction drawing information to the AR equipment so that the AR equipment displays the BIM corresponding to the current spatial position information or the construction drawing information.
The method comprises the steps of sending a BIM corresponding to current spatial position information or construction drawing information to AR equipment, namely sending BIM data corresponding to the BIM corresponding to the current spatial position information or construction drawing information to the AR equipment, and displaying the BIM in an all-dimensional mode through the AR equipment.
From the above description, it can be seen that, in the method for displaying a BIM model in the embodiment of the present application, first, the AR device determines current spatial position information or construction drawing information through a spatial position calculation and recognition function; sending the current spatial position information or the construction drawing information to the server; after receiving current spatial position information or building drawing information sent by AR equipment, the server matches BIM models corresponding to the current spatial position information or the building drawing information from all BIM models according to the current spatial position information or the building drawing information, wherein all BIM models are all BIM models corresponding to the whole building structure; sending the BIM corresponding to the current spatial position information or the construction drawing information to the AR equipment; and enabling the AR equipment to receive and display the BIM corresponding to the current spatial position information or the construction drawing information sent by the server. In this application, can show BIM model through AR equipment, compare with current VR equipment show BIM model that uses, show more all-round, can improve BIM model's rate of utilization.
As a further supplement and refinement to the above embodiments, according to the embodiments of the present application, another method for BIM model display is provided, as shown in fig. 2, the method includes the following steps:
s201, the server side obtains the classification screening requirements sent by the AR equipment.
The classified screening requirement is that the user sends the information to the AR equipment through voice so that the AR equipment receives the information. An example of specific classification screening requirements is given for explanation, and if a user wants to view a BIM model of a water heating pipeline in a certain building, the corresponding classification screening requirements may be the water heating pipeline; if the user wants to see the BIM model of a certain floor of a certain building, the corresponding classification screening requirement can be the Xth floor first.
S202, the server side screens the BIM which meets the classification screening requirements from all the BIM based on the artificial neural network model according to the classification screening requirements.
The input of the artificial neural network model in this step is category keywords extracted from the classified screening requirements, and the output is the identification information of the BIM model corresponding to the category keywords. The artificial neural network model is also obtained by training according to the training sample.
And extracting category keywords after the server side obtains the classification screening requirements, outputting the category keywords to the artificial neural network model in the step, obtaining the identity identification information of the BIM model corresponding to the classification screening requirements, and searching in a database according to the identity identification information of the corresponding BIM model to obtain the BIM model corresponding to the classification screening requirements.
Step S201 and step S202 are equivalent to performing a weight reduction process on all BIM models, so that efficiency can be improved when matching the BIM models to be displayed subsequently.
And S203, the AR equipment determines the current spatial position information or the construction drawing information through a spatial position calculating and identifying function.
The current spatial position information or the construction drawing information in this embodiment is the same as the current spatial position information or the construction drawing information in step S101 in fig. 1, and is not described herein again.
And S204, the AR equipment sends the current spatial position information or the construction drawing information to the server.
And S205, matching a BIM corresponding to the current spatial position information or the building drawing information from the BIM meeting the classification screening requirement based on the artificial neural network model according to the current spatial position information or the building drawing information.
Specifically, the implementation of this step includes: firstly, matching the identity of a BIM (building information modeling) model corresponding to current spatial position information or building drawing information from BIM models meeting the classification screening requirements based on an artificial neural network model according to the current spatial position information or the building drawing information; and searching a BIM corresponding to the identity from a database according to the identity, and correspondingly storing all BIM in the database and the corresponding identity.
It should be noted that the input of the artificial neural network model in this step is current spatial position information or construction drawing information, and the output is the unique identity of the BIM model.
In addition, description is made regarding storage of the BIM model in the server: firstly, a server side obtains original files of all BIM models of the whole building and formats the original files; and the formatting process is to analyze and convert the original file of the BIM model into file data which is in line with the calling of a server and is in line with the storage of a database. And then, correspondingly storing the formatted BIM in a database according to the identity. And storing the BIM and the corresponding unique identity according to a storage mode of a relational structure, wherein the specific BIM is stored in a database in the form of BIM data.
S206, the server side obtains real-time data of real equipment corresponding to the BIM corresponding to the current spatial position information or the construction drawing information through a data transmitting port of the sensor.
The sensor is a device used for detecting and acquiring equipment implementation data on actual equipment corresponding to the BIM model. The real-time data can be temperature, humidity, water flow speed, direction and the like, and the corresponding real-time data of different equipment is different. In practical application, in order to monitor real-time data, the sensor needs to send the real-time data to the data center or the management center in real time or at intervals through the data transmitting port, so that the server can acquire the real-time data by connecting the data transmitting port.
And S207, the server side superimposes the real-time data and the BIM corresponding to the current spatial position information or the construction drawing information and sends the superimposed BIM to the AR equipment.
And S208, the AR equipment displays the BIM corresponding to the current spatial position information or the construction drawing information and the real-time data in an overlapping mode.
During the display in a superimposed manner, if the real-time data is real-time data of a plurality of devices, the real-time data needs to be superimposed to the corresponding positions of the corresponding devices for display.
Furthermore, the embodiment can also perform intelligent prediction, that is, a BIM model which may need to be displayed by the user in the next step is predicted to be displayed according to the action of the user and the change of the visual field visible range. The principle of the specific intelligent prediction is to predict the change of the current spatial position information, determine the predicted spatial position information, then match and display the BIM model corresponding to the predicted spatial position information according to the predicted spatial position information, and the implementation manners of matching and displaying the BIM model corresponding to the predicted spatial position information and matching and displaying the BIM model corresponding to the current spatial position information are the same, and are not repeated here. It should be added that how to determine the predicted spatial location information, the specific principle is that the AR device determines the predicted spatial location information according to the real-time data of the change of the spatial location of the AR device and/or the change of the visual direction of the user wearing the AR device and the current spatial location information. Namely, on the basis of the current spatial position information, the predicted spatial position information is obtained by calculation and synthesis according to the changed real-time data. The intelligent prediction is carried out according to the action of the user and the change of the visual field visible range, and the BIM model display speed can be improved.
Further, this embodiment provides an architecture schematic diagram corresponding to the BIM model display method, as shown in fig. 3, including an AR device, a Data interface (Data API), a server, a BIM model original file, and a sensor. The AI edge calculation refers to the initial calculation of data based on an end at an AR equipment end, and mainly refers to the determination of space position information; the AI intelligent prediction mainly refers to matching a pre-displayed BIM model according to predicted spatial position information; "DataAPI" refers to the data acquisition, access layer; the intelligent analysis of data part is mainly the analysis, storage and matching of BIM model.
It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order different than presented herein.
According to an embodiment of the present application, there is also provided an apparatus for performing BIM model display of the method described in fig. 1 to 2, as shown in fig. 4, the apparatus includes:
