Specific embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to each reality of the invention
The mode of applying is explained in detail.However, it will be understood by those skilled in the art that in each implementation method of the invention,
In order that reader more fully understands the application and proposes many ins and outs.But, even if without these ins and outs and base
Many variations and modification in following implementation method, it is also possible to realize the application technical scheme required for protection.
First embodiment of the invention is related to a kind of implementation method of three-dimensional BIM images, its idiographic flow such as Fig. 1 institutes
Show.The embodiment of Fig. 1 can apply to portable electric appts, such as smart mobile phone, panel computer, personal digital assistant PDA
(Personal Digital Assistant, personal digital assistant, abbreviation PDA), etc..Specifically, the method flow bag of Fig. 1
Include：
Step 101：Load the parametrized drawing data for generating three-dimensional BIM images.
Wherein, the parametrized drawing data in step 101 can be obtained from various modeling softwares, for example：Revit,
Some parametrized drawing data can be obtained in the modeling software of Tekla, MagiCAD etc..In actual applications, it is soft from modeling
Different grades of parametrized drawing data, the parametrized drawing that for example a BIM model can get can be got in part
Data can include one below or its any combination：Basic geometric parameters DBMS, face data DBMS.Wherein, it is substantially several
What parametric degree data includes the minimum geometric parameter for generating geometric figure, and face data level data are included by minimum geometric parameter
The data in the face of generation, and basic geometric parameters DBMS and face data DBMS are used to generation component, i.e. parametrized drawing
Data are set in units of component.Wherein, each DBMS is respectively to that should have preset algorithm for according to this grade of parametrized drawing
Data draw component.So being adopted, it is necessary to be directed to the parametrized drawing data for getting when complete three-dimensional BIM images are built
Component is repainted with its corresponding preset algorithm.
Present embodiment by taking this kind of building element of water pipe as an example, different grades of parametrized drawing data are illustrated as
Under：
If it is understood that the diameter (it is assumed that water pipe be all circular) of water pipe, source location set and final position point, as long as
Having these three data can just draw the water pipe.If starting point, two rounded faces in final position of outlet pipe are calculated, then will
The two rounded faces are connected to be formed to draw by lateral cylindrical face and obtain water pipe, and the fineness of water pipe rounded face completely can be with
Control according to demand.Because there is these three data, the geometric data of the volume, area and various needs of water pipe can
Get.Therefore, such data are the data volume minimum and the most perfect parametrized drawing number of function for generating three-dimensional BIM images
According to such data are the basic geometric parameters DBMS in present embodiment.When cannot from modeling software direct access
During to foregoing basic geometric parameters DBMS, several face data of water pipe can also be obtained, such as water pipe two ends (or top surface
And bottom surface) rounded face and water pipe side the face of cylinder.So the water pipe can just be described by the geometric expression formula in face,
When the water pipe is drawn, it is necessary to parse the geometric expression formula in face by geometry teaching to obtain the drafting information in face, so obtain
The rounded face of the water pipe for taking and the fineness on the face of cylinder are also controllable.
And substantial amounts of tri patch graph data is generally included in existing modeling software.The such as one figure number of water pipe
According to if being stored using tri patch, then not only its data volume be it is maximized, and this data geometry implication
It is also zero, that is to say, that this tri patch data of water pipe are do not have other function in addition to for showing figure,
In other words, it just corresponds to a picture.Therefore, present embodiment replaces with base by by the graph data of tri patch class
This geometric parameter DBMS, face data DBMS so that the data volume of same BIM models can save decades of times to hundreds of
Times.Meanwhile, the various demands of BIM, such as basic three-dimensional data can be still completed by these graph datas for parameterizing
Realize, 2-D data displaying, optimized algorithm that some are rendered realized, the rendering accuracy of water pipe is dynamically realized according to distance
Etc., have parametrized drawing data for realizing the various demands of software, be traditional modeling software mode can not than.
Therefore, in a step 101, when needing to realize three-dimensional BIM images, in order to reduce data volume, reduce to equipment
The requirement of energy, uses light-weighted parametrized drawing data in BIM models.
Step 102：According to parametrized drawing data at different levels and the corresponding preset algorithm generation of parametrized drawing data at different levels
Three-dimensional BIM images.
Step 103：Display three-dimensional BIM images.
In a step 102, various components are drawn using the parametrized drawing data for getting according to geometrical principle.Work as acquisition
When the parametrized drawing data for arriving are basic geometric parameters DBMS, it is possible to which the internal relation according to basic geometric parameters is utilized
Geometrical principle draws component, when the parametrized drawing data for obtaining are face data DBMS, then can be according in the data of face
In relation component is drawn using geometrical principle.
Water pipe is exactly in fact a kind of cylinder, also some other geometric descriptions, such as cube, cone, spheroid, is drawn
Body, circumgyration stretch body, setting-out body etc. are stretched, can be according to geometrical principle Fast Drawing.Regardless of whether being simple objects or multiple
Debris body major part can be broken into basic body, is combined by basic body and is formed.
In actual applications, attribute data can be tied to parametrized drawing data.Each component is generally wrapped in BIM models
Include respective attribute data, attribute data for example the key words sorting including component, title, size, construction requirement, installation method,
Installation site etc..Due to including key words sorting in the attribute data of component, key words sorting is for example carried out according to the specialty of component
Classification.So when the 3-D view of BIM is checked, can be shown according to the demand classification of different majors, such that it is able to enter
Requirement of the one step reduction BIM model displays to equipment process performance.
The now application to the attribute data in BIM models in the present embodiment is illustrated：From building itself
Characteristic is set out, when the attribute data to BIM models is divided, can be according to the several basic division of floor, specialty, type etc.
Condition is divided.Such as wall and water pipe can be divided to different specialties, and wall can also be divided into more according to function
Type, such as curtain wall, structural wall etc..Some dividing modes, such as setting some same models can certainly be manually set
Standby to divide one group into, the pipeline of some suitable specifications divides one group etc. into.In a word, can be according to user, the demand of software, to BIM moulds
Various components in type are classified, and the relation of classification is stored.
In addition, the implementation method of the three-dimensional BIM images of present embodiment both to have can apply to process performance relatively good
PC (Personal Computer, PC) ends, NB (NoteBook, notebook) ends, it is also possible to for portable terminal,
Such as smart mobile phone, panel computer etc..For different terminal devices, different applications can also be realized, to a certain extent
The light-weighted purposes of BIM can also be reached.
First to desktop computer or this Performance comparision of notebook terminal high, forced because it can be competent at high-volume, height
Genuine model display, high-volume data processing, calculating and typing compare the intuitively various functions such as data display management, at this
Some advanced BIM functions can be reserved in the terminal of type.Followed by this for mobile phone or panel computer match somebody with somebody
More relatively low mobile terminal is put, because its is easy to carry, various real-time operations can be at the scene carried out, it is possible to carry
For real-time on-site data gathering, such as take pictures, record, record problem etc., in the case where network signal is allowed, can send
Message, the simple data of typing etc..But because equipment performance has bottleneck, so can not distribute heavy as desktop computer
Work.Therefore in terms of model display, can be processed with zoning, such as only show a model for floor, or one
The model of specialty, or the mode such as floor and combination of major, are met on mobile terminals by by model partition being more fritter
The demand being shown.It is worth noting that, for this screen of mobile terminal is not too big equipment, showing excessive
Data can allow user to feel redundancy on the contrary, therefore, the value being shown on mobile terminals is to show the number for needing displaying
According to, rather than show all of data, therefore, in the application aspect of BIM models, then can as far as possible by the data of minimum
To meet the demand of user.
Present embodiment is directed to and is difficult to the huge BIM of processing data on the electronic equipment of mobile terminal etc. in the prior art
The problem of model, getting parms graph data substitutes the data of existing tri patch etc. from modeling software so that data
Amount is greatly reduced, meanwhile, component is drawn using the parametrized drawing data for getting according to geometrical principle, and then three can be realized
Dimension BIM models, the displaying of two dimension BIM data.
Second embodiment of the present invention is related to a kind of implementation method of three-dimensional BIM images.Second embodiment is first
Improvement is made on the basis of implementation method, is mainly theed improvement is that：In this second embodiment, by limiting BIM pattern numbers
According to storage mode so that it is more efficient in real-time rendering three-dimensional BIM models.
Specifically, the flow chart of the implementation method of the three-dimensional BIM images of second embodiment is as follows：
Step 201：By parametrized drawing data storage in database.
Wherein, ginseng is worked as, it is necessary to be analyzed to parametrized drawing data to be stored when parametrized drawing data are stored
Numberization graph data meet first it is pre-conditioned when, by parametrized drawing data storage in the field of database table, work as parameter
Change graph data meet second it is pre-conditioned when, parametrized drawing data are saved as into binary stream data block.Wherein, first is pre-
If condition is more than default access frequency for the access frequency of parametrized drawing data, second it is pre-conditioned can for one below or
Its any combination：The data volume of parametrized drawing data is more than default access speed, data more than preset data amount, access speed
Change is component data more than default changing value, parametrized drawing data.In other words, the parametrization higher for enquiry frequency
Graph data, the attribute data for example bound with parametrized drawing data, can store it in the field of database table, carry
Data search efficiency high.And need not be inquired about for some, access speed is high, data variation is larger data are then with binary stream
Data block mode is stored.Stored in database with binary stream data block mode by by parametrized drawing data, can
Complex parametrized drawing data are stored to avoid designing literary name section in database, data storage is reduced, is accessed multiple
Miscellaneous degree, is conducive to improving access speed.
Furthermore it is also possible to the multiplexing for passing through component data reduces the data volume of entirety BIM models.Generally, parametrized drawing
Data can include that some is one with the one-to-one components pattern data of component, the i.e. minimum unit of parametrized drawing data
Component data cell.When BIM includes multiple identical components, one is stored in database and corresponds to multiple identical structures
The components pattern data of part.Have 100 same chair in such as one office, if also using 100 in model
Individual data deposit the increase data volume that chair will be unnecessary, and the way of present embodiment only needs to store a chair
Data, and chair hundred can be entered line translation and obtain by this by the data of this chair.For BIM models, largely
Component between there is repeatability, therefore, use this kind of data multiplexing technique for identical component, can equally save a large amount of
Data, be conducive to the lightweight of BIM.
Step 202：Load the parametrized drawing data for generating three-dimensional BIM images.
In some cases, the data for being obtained from database need parse obtaining intermediate data, if from data
The parsing duration of the parametrized drawing data obtained in storehouse is more than default parsing duration, or the data volume that parsing is obtained is more than pre-
If parsing data volume, then in step 201, the data that obtain of parsing can be preserved to local, so that in step 202., can be with
The data that the parsing preserved from local loading is obtained.
Due to reading out parametrized drawing data (i.e. lightweight data) from database afterwards, it is necessary to resolve to what can be rendered
Graph data, because the parsing time of the graph data that can be rendered may be more long, can have a strong impact on Consumer's Experience.Wherein, can wash with watercolours
The graph data of dye refers to the image being eventually displayed in terminal, that is, foregoing tri patch.Wherein, finer figure
Picture, including tri patch it is more, although and light-weighted data can be simplified very much, the graph data of final rendering is necessary
Being converted to tri patch could show.For example, to one spheroid of display, then lightweight data can be that a centre of sphere adds
One radius, but the spheroid graph data of final rendering then includes a fairly large number of tri patch, that is, and the spheroid for showing is more smart
Carefully, the tri patch for rendering is more, therefore resolving is exactly that, by lightweight data, a centre of sphere adds a radius, raw
Tri patch on substantial amounts of spheroid, this resolving contains some geometric algorithms, with the complexity of different algorithms
Degree is different, and the time complexity needed for calculating is also variant, therefore, the parsing of the lightweight data of whole BIM models is superimposed upon
Together, may cause to consume longer time.Therefore, it can for some to take rendering of being generated of resolving more long
Graph data is preserved to local.
Preserve the intermediate data that obtains of parsing to it is local when, can specifically parse the intermediate data for obtaining with binary system
Stream file form is directly preserved to local hard drive, without being stored in database.Due to being directly from local hard drive receive data
According to so access speed from data compared to line access is entered faster, it only needs binary stream file to be opened up in tag memory
Open.These binary stream files are typically all the data access of file-level, so the internal storage structure after launching is fixed, and
Data in database are component ranks, therefore can individually access component data according to demand so that the combination spirit of data
Activity is bigger.
Step 203：According to parametrized drawing data at different levels and the corresponding preset algorithm generation of parametrized drawing data at different levels
Three-dimensional BIM images.
Step 204：Display three-dimensional BIM images.
When existing BIM models are applied on mobile terminals, situation about typically encountering is, if the data of loading are too many too
Greatly, software crash, or CPU (Central Processing Unit, center treatment may be caused due to Out of Memory at any time
Device) do not process stuck, or video card renders too slow interim card etc., and present embodiment can then be tackled using following methods.
It is for instance possible to use dynamic loading, the method for unloading data, such as in step 203, if current system is deposited
The occupation proportion for storing up space is more than predetermined threshold value, then unloading is more than untapped data of default waiting time.For example, predetermined threshold value
Can be 80%, i.e., when mobile terminal main memory or video card display memory use ratio more than 80% when, then carry out
The unloading of data, will be greater than default waiting time untapped load shedding and falls, or, then may be used for some data not used
Directly to uninstall, the utilization ratio of internal memory is improved.Those skilled in the art can determine needs according to user function demand
Loading and the data of unloading, present embodiment are not restricted for its specific implementation.Therefore, the core of present embodiment exists
In equalization point can be found in user function demand and equipment performance, so as to realize the maximum value of mobile terminal.
Furthermore it is also possible to some data conversions for expending CPU and internal memory are transferred out, other time, or handle is placed on
During these are operated to equalization to less operation, such that it is able to reduce period of reservation of number, or software crash is avoided.Specifically
Ground, obtains the corresponding operational set of preset algorithm, and operational set includes some operational orders, estimates estimating for each operational order occupancy
Meter handling duration, obtains estimating that handling duration is more than the first operational order of default handling duration, and adopt the first operational order
Processed with following either type：The first operational order is sent to obtain the corresponding operating result of the first operational order.So as to by one
The transition of operation that a little this mobile terminal are not processed is processed to such as server, cloud platform.Or, by the first operational order
Some second operational orders are decomposed into, wherein the estimation handling duration of the second operational order is less than default handling duration, so as to keep away
Exempt from software crash.
Above the step of various methods divide, be intended merely to description it is clear, can be merged into when realizing a step or
Some steps are split, multiple steps are decomposed into, as long as comprising identical logical relation, all in the protection domain of this patent
It is interior；To adding inessential modification in algorithm or in flow or introducing inessential design, but its algorithm is not changed
With the core design of flow all in the protection domain of the patent.
Embodiment of the present invention is by efficient data base administration mechanism, dynamic data loading, unloading, by cloud platform etc.
Powerful data processing function, and reduce the methods such as the equipment performance requirement of single operation and ensure in disposal ability relatively
Realize that BIM is applied on weak mobile terminal, be application of the BIM technology in engineering project such that it is able to improve BIM application scenarios
The obstacle of reduction, the more personnel allowed in project can be linked up by BIM technology, coordinate solve problem, more effectively complete
On the premise of appointed task, it is also possible to effectively promote the development and propagation of BIM technology.
What third embodiment of the invention was related to a kind of three-dimensional BIM images realizes device, and its structure is as shown in Figure 3.This three
That ties up BIM images realizes that device can apply to portable electric appts, and such as smart mobile phone, panel computer, individual digital are helped
Reason PDA (Personal Digital Assistant, personal digital assistant, abbreviation PDA), etc..Specifically, the three-dimensional BIM
Image realizes that device 300 includes：

Wherein, parametrized drawing data can be obtained from various modeling softwares, for example：Revit, Tekla, MagiCAD
Deng modeling software in can obtain some parametrized drawing data.In actual applications, can be obtained from modeling software
To different grades of parametrized drawing data, the parametrized drawing data that such as one BIM model can get can include
One below or its any combination：Basic geometric parameters DBMS, face data DBMS.Wherein, basic geometric parameters DBMS
Including the minimum geometric parameter for generating geometric figure, face data level data include the number in the face generated by minimum geometric parameter
According to, and basic geometric parameters DBMS and face data DBMS are used to generation component, i.e., parametrized drawing data are with component
For unit is set.Wherein, each DBMS is respectively to that should have preset algorithm for drawing component according to this grade of parametrized drawing data.
So when complete three-dimensional BIM images are built, it is necessary to be directed to the parametrized drawing data for getting and corresponding pre- using its
Imputation method repaints component.
Present embodiment by taking this kind of building element of water pipe as an example, different grades of parametrized drawing data are illustrated as
Under：
If it is understood that the diameter (it is assumed that water pipe be all circular) of water pipe, source location set and final position point, as long as
Having these three data can just draw the water pipe.If starting point, two rounded faces in final position of outlet pipe are calculated, then will
The two rounded faces are connected to be formed to draw by lateral cylindrical face and obtain water pipe, and the fineness of water pipe rounded face completely can be with
Control according to demand.Because there is these three data, the geometric data of the volume, area and various needs of water pipe can
Get.Therefore, such data are the data volume minimum and the most perfect parametrized drawing number of function for generating three-dimensional BIM images
According to such data are the basic geometric parameters DBMS in present embodiment.When cannot from modeling software direct access
During to foregoing basic geometric parameters DBMS, several face data of water pipe can also be obtained, such as water pipe two ends (or top surface
And bottom surface) rounded face and water pipe side the face of cylinder.So the water pipe can just be described by the geometric expression formula in face,
When the water pipe is drawn, it is necessary to parse the geometric expression formula in face by geometry teaching to obtain the drafting information in face, so obtain
The rounded face of the water pipe for taking and the fineness on the face of cylinder are also controllable.
Present embodiment is directed to and is difficult to the huge BIM of processing data on the electronic equipment of mobile terminal etc. in the prior art
