The MR mixed reality technology provides a virtual reality combined interactive solution for project surrounding environment analysis, historic building protection, city planning, project scheme comparison and project planning approval in the planning and reporting process.

S103: and exporting unified format files for establishing hyperlink data in the BIM by adopting a lightweight tool, and respectively applying the unified format files to the BIM scene, the GIS scene and the VR scene.

The lightweight tool compresses and encrypts data by using a Lzma compression algorithm to further obtain lightweight geometric data, and converts GIS data, drawing data, document data, process data and service data into a uniform format file by using the Lzma compression algorithm, wherein the uniform format file comprises the lightweight geometric data.

At present, the BIM is almost stored in a file mode, is an independent model file, is discrete data, and cannot be effectively integrated, mined and processed. The BIM data platform at the cloud side needs to be established, data needs to be structured, only structured BIM data can be used as the basis of BIM big data and can be better associated with other structured and unstructured data, so that the realization of the planning approval platform firstly needs to extract BIM data from different dimensions and stores and applies the BIM data according to reasonable structure and hierarchy, reasonable utilization of land is most concerned in the planning approval process, the comparison of areas or areas such as construction land, greening land, planning land and the like is a land management data source, and the structured data can provide convenience for comparison and display of various area data more flexibly.

The data preparation and conversion need to include two levels of data, one is GIS data, the GIS data needs to include processing of image, terrain, inclination and point cloud data, the other is BIM data, the conversion of the BIM data needs to support the currently popular mainstream BIM platform, simplified models in GIS display need to be converted at the same time, and meanwhile, the requirement for detailed BIM model data in the approval process also needs to be met. The GIS three-dimensional geographic information system is fused with the BIM graphic engine, so that the actual comparison of a planning scheme can be conveniently carried out according to the actual spatial position of a coordinate positioning project more visually, and the BIM data is utilized more fully.

The common point of the data format files generated by different BIM software is that the capacity is large, 10GB is added to a project full-professional model data, and 1GB is also added to a planning and reporting BIM data model file, so if lightweight model data conversion is not carried out, the model original data is simply taken in, a large number of reporting projects can cause the requirement of a large amount of storage hardware, and the purchasing cost is increased; meanwhile, a large amount of reported and established data consumes computer hardware resources, and at least five minutes are needed for opening a model for examination, so that time is wasted, and the administrative examination and approval efficiency is reduced.

S104: and storing the unified format files in the BIM scene, the GIS scene and the VR scene so as to enable the building performance index statistics to be checked, wherein the building performance index statistics checking comprises large scene performance index statistics, single model performance index statistics and multi-terminal data checking.

Referring to fig. 2, a BIM model is created based on a Revit model and an AECOsim model, wherein the BIM model is created according to Revit model specifications and AECOsim model specifications, then a local conversion plug-in, i.e., a lightweight tool, is used for data conversion, if data verification is not passed in the data conversion process, the BIM model is returned again for processing, files in a unified format are uploaded and applied to BIM + GIS + VR multiple scenes, and the unified format files in the BIM scene, the GIS scene and the VR scene are stored so that building performance index statistics can be checked, and large scene performance index statistics, single model performance index statistics and multi-terminal data checking can be obtained through background data extraction.

The BIM model data is stored in a lightweight and structured mode: in the whole cycle of the BIM project, project documents, components in the documents, attribute information, geometric information, material information and the like of the components are indispensable components. The structured storage algorithm of the data can store a large amount of data information in a light weight mode. The BIM platform realizes rapid and light collaborative management and shows BIM projects through an algorithm of structured storage data. The geometric data is the most intuitive data and is the core part of the whole algorithm. The geometry processed by the algorithm is a three-dimensional geometry and does not contain pure two-dimensional geometries such as straight lines, points and the like.

Geometric data storage principle: a component may be composed of a plurality of identical or different geometric bodies, which at the same time may be composed of different, smaller minimum geometric body elements. Different members may have the same minimum geometric units or different minimum geometric units. The geometry that can no longer be segmented is the smallest geometry unit. The position of the smallest geometric unit in the member is realized by a transformation matrix.

The geometric data multiplexing is realized as follows: the geometric body information of the member comprises the following types: geometric solid, face, geometric example. The surface is composed of three-dimensional point coordinates, material coordinates and triangular grid indexes of the point coordinates. Geometric solid, consisting of faces. And the geometric example consists of a geometric example, a geometric solid and a surface. The geometric information of the member is read, and the geometric entity and the surface are directly stored as the minimum geometric unit by taking the same material ID as a unit. Reading the geometric information of the member, and for the geometric example, recursively traversing the internal information of the read geometric example to end up being unable to traverse to the geometric example. In the process of recursively traversing the geometric examples, reading the ID of the geometric examples and the transformation matrix, grouping and storing the geometric entities and the geometric surfaces into the minimum geometric unit by taking the same material ID as a unit and taking the ID of the geometric examples + the material ID as a new geometric body ID, and calculating and storing the transformation matrix. And separately storing the minimum geometry unit and the geometry ID read in the process of traversing the geometry example into the minimum geometry multiplexing container. In the process of reading the geometric information of the component, searching a minimum geometric multiplexing container while recursion, directly multiplexing the minimum geometric when the same geometric ID is encountered, and additionally calculating and storing a transformation matrix. And if the same geometry ID cannot be found in the minimum geometry multiplexing container, the read geometry entity is faced, the geometry instance ID + the material ID is used as a new geometry ID, the geometry instance ID + the material ID is grouped and stored as a minimum geometry unit, and the transformation matrix is calculated and stored at the same time.

Geometric data storage implementation. And for the minimum geometric unit, storing three-dimensional point coordinates, material coordinates and triangular grid indexes of the point coordinates in a triangular grid mode. And compressing and encrypting the point coordinates, the material coordinates and the point sequence by using an Lzma compression algorithm, and finally realizing lightweight geometric data.

External software dependencies: the BIM + GIS reporting platform realized based on the internet technology does not depend on foreign software to carry out secondary development of software functions, reserves various expansion interfaces, provides convenience for planning and reporting multi-platform data sharing and data management, and reduces the difficulty of updating and upgrading the platform.

And (3) personnel management and control authority allocation: personnel authority management is flexible and diverse, a planning approval platform manager can perform approval authorization on approval for approval demand personnel on line, and the approval personnel can apply for, approve and the like planning approval work at any place at the present of gradual popularization of a network based on the internet technology.

The online measurement function is as follows: the planning and reporting platform based on BIM + GIS can realize the measurement of the spatial relationship among buildings on line, provides a real scene and a judgment tool for planning and reporting approval, does not need to search the surrounding building archive data of a project, provides help for decision analysis such as project construction planning, soil utilization condition, environmental influence and the like, and improves the approval efficiency of planning and reporting. Measurement function: distance-space measurement, distance-ground contact measurement, area measurement, angle measurement, height-height difference measurement, height-triangulation measurement, and floor-to-floor planar distance measurement.

The specification limiting factor is: due to the characteristics of the information model and the object-oriented classification mode of all the components of the information model, a simple and convenient classification basis is provided for information extraction and selection. And the compilation of 'BIM information model submission standard for planning and approval of Guangzhou city cities' provides standard constraint for future planning and submission, so that the universal application of a planning and submission platform based on BIM + GIS is provided.

The information interaction mode is as follows: the planning review platform based on the BIM + GIS can provide a more real and humanized interaction mode besides the traditional interaction mode (such as a keyboard, a mouse, touch equipment, a microphone and the like), such as a VR/MR interaction mode based on voice, touch, eye movement, gestures and body feeling.

Information security: a planning review platform established based on a private cloud provides various solutions from hardware and software angles for guaranteeing data security, such as encrypted data transmission, digital-analog separation and the like.

At present, BIM design software in the field of construction engineering is numerous, BIM technical solutions of each unit are different, selected BIM design software is also different, three platforms including Autodesk, Microstation and Catia which are mainstream in the market at present have different data formats, and a design institute cannot be appointed to adopt certain platform software, so that a BIM planning and reporting platform needs to be capable of reading and recording the BIM format data of the three mainstream.

At present, BIM design, construction, operation and maintenance software is foreign software basically, BIM information of engineering projects contains a large amount of data, and the data can have obvious influence on information safety and enterprise risk. Under the confidential environment of intranet operation, foreign software with uncertain security factors should not be deployed, so that the localization of the BIM report review software is very important, and the complete localization comprises a core of the software, namely a BIM graphic engine.

The original two-dimensional planning reporting and building software increases the design cost of a design unit, and special personnel are needed to make and check reporting and building data. The three-dimensional BIM planning and reporting emphasizes that the cost of additional BIM model construction of a design unit is not increased, the statistics of area data attributes is automatically carried out by assigning the attribute information of the model space, and the labor cost for manufacturing reporting and reporting files in the prior art is reduced.

The invention improves the spatial experience of BIM approval and establishment and realizes the sharing of BIM data in the GIS. The GIS three-dimensional geographic information system is fused with the BIM graphic engine, so that the actual comparison of a planning scheme can be conveniently carried out according to the actual spatial position of a coordinate positioning project more visually, and the BIM data is utilized more fully.
