Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building information fusion, and particularly relates to a method and device for supporting multi-terminal BIM and GIS fusion. BACKGROUND

[0002] BIM (Building Information Modeling) and GIS (Geographic Information System) are important information technologies in modern engineering construction and urban planning. BIM is mainly used for the design and management of buildings, while GIS is used for the storage, analysis and visualization of geographic spatial data. With the development of technology, combining BIM and GIS and displaying and interacting through the Web can greatly improve the efficiency and effectiveness of building information management and urban planning.

[0003] At present, the existing technology realizes the fusion of Web-end BIM and GIS by using an open-source WebGL graphics engine and an open-source GIS global map Web library to realize the fusion of BIM and GIS on the Web. Under this technical scheme, the graphics engine and the GIS engine are realized by superimposing on the web page. The existing technology usually uses a WebGL graphics engine (such as three.js) on the Web to realize the rendering of BIM objects, and the display effect of the WebGL graphics engine on the Web is general, and there is a large difference from the actual model of the physical world. On the PC, a rendering engine is used to render BIM objects, but since the map engine cannot cross platforms, it cannot realize the fusion of BIM and GIS on the Web. The existing rendering engine supports cross-platform operation, and the GIS global map engine supports cross-platform operation, but the GIS map engine only provides a non-Web technical solution of the rendering engine, so it can only realize the fusion of BIM and GIS on the non-Web. If the existing technical solution is used, the superimposed display is still performed on the Web page, and the Web JavaScript library of the rendering engine and the JavaScript library of the GIS engine are used for development. Under this technical solution, the development complexity is large, the development project cannot have flexibility and reusability, and deep fusion of BIM and GIS cannot be realized.

[0046] Embodiment 1

[0047] With reference to Figure 1 Embodiment 1 of the present application provides a method for supporting multi-end BIM and GIS fusion, comprising the following steps:

[0048] S1, selecting a C++ library of a GIS map engine as a source library for fusion; according to the set functions of the C++ library of the GIS map engine, the C++ library of the GIS map engine is divided into a plurality of GIS map engine C++ function libraries;

[0049] S2, compiling the plurality of GIS map engine C++ function libraries respectively by using an open source compilation tool chain, to obtain a plurality of browser executable format libraries meeting the requirements of running in a browser;

[0050] S3, performing interface encapsulation processing on the plurality of browser executable format libraries by using a readable programming language, to obtain a plurality of browser-side libraries; the browser-side libraries are provided with a unified interface layer;

[0051] S4, using a rendering engine code language by a rendering engine, and calling the browser executable format libraries of the GIS map engine by using the interface layer of the browser-side libraries, to realize reading and processing of geographic spatial data in the GIS map engine;

[0052] S5, after the rendering engine completes the calling of the browser executable format libraries of the GIS map engine, compiling the rendering engine into a WebGL platform or a PC platform by using a configured strategy, to realize fusion display of BIM rendering engine and GIS map engine data.

[0053] In this embodiment, in step S1, a C++ library of a GIS map engine is selected as a source library for fusion; according to the set functions of the C++ library of the GIS map engine, the C++ library of the GIS map engine is divided into a plurality of GIS map engine C++ function libraries;

[0054] Specifically, the existing code library of the GIS map engine is generally divided into a C++ library, a game engine library and a Web library for external use. In order to realize deep application of the bottom interface of the GIS map engine and deep fusion from the bottom, the C++ library is selected as the source library for fusion.

[0055] In practical applications, the complete GIS map engine C++ library often has many functions and is large in size. In some specific BIM and GIS integration scenarios, only part of the functions of the GIS engine may be needed. In order to improve the flexibility and lightness of the system, the present application proposes a method for split compilation of a GIS map engine, which splits the C++ library of the GIS map to form multiple browser executable format libraries for the rendering engine. The rendering engine can call the browser executable format library of the GIS engine as needed to achieve flexibility and lightness. The GIS map engine is analyzed to determine its various functional modules and interfaces. For example, the GDAL library of the GIS map engine is split according to functional modules such as data reading, data processing, and map rendering. The C++ code of each module should be relatively independent and have preset input and output interfaces.

[0056] In this embodiment, in step S2, a number of GIS map engine C++ function libraries are respectively compiled by an open source compilation tool chain to obtain a number of browser executable format libraries that meet the requirements for running in a browser;

[0057] Specifically, referring to Figure 2 The C++ code of each functional module is individually compiled using a browser executable format compilation tool chain to generate independent browser executable format libraries. During the compilation process, the code and resources corresponding to the functions of each GIS map engine C++ function library are compiled to reduce the size of the browser executable format libraries, thereby reducing the size of the browser executable format libraries.

[0058] As shown in Figure 3 the specific compilation steps are as follows:

[0059] S21, select the GIS map engine C++ function library that needs to be compiled;

[0060] S22, install the browser executable format file compilation tool chain;

[0061] S23, download and decompress the source code package of the GIS map engine, enter the source code directory, and ensure that the source code can be compiled in the local C++ compilation environment;

[0062] S24, write the compilation file of the GIS map engine C++ function library;

[0063] S25, configure and compile the C++ function library of the GIS map engine by using the compilation tool chain to convert the C++ function library of the GIS map engine into the browser executable format library.

[0064] The application realizes flexibility and light weight of the GIS map engine. The rendering engine can load and call the browser executable format library of each function module on demand, thereby reducing system resource occupation and improving operation efficiency.

[0065] In the embodiment, in step S3, the browser executable format libraries are interface-encapsulated by a readable programming language to obtain a plurality of browser-side libraries; the browser-side libraries are provided with a unified interface layer.

[0066] Specifically, since the browser executable format is a compilation target, the readability is poor. In order to improve the readability of the browser executable format library and facilitate development and application, the application provides a method for encapsulating the browser executable format library formed by the C++ library of the GIS engine, so that the subsequent rendering engine can better access the underlying interface of the GIS engine.

[0067] As shown in Figure 4 The generated browser executable format library is encapsulated by a readable programming language to provide an interface with strong readability and high usability of the browser executable format library. The interface realizes loading and calling of the browser executable format library and provides an easy-to-use access interface, so that the rendering engine can use its own programming language to schedule and call.

[0068] In step S4, the rendering engine uses the rendering engine code language and calls the browser executable format library of the GIS map engine through the interface layer of the browser-side library, so as to realize reading and processing of geospatial data in the GIS map engine.

[0069] Specifically, as shown in Figure 5 In the rendering engine, the browser executable format library of the GIS map engine can be called through the interface layer of the browser-side library to realize reading and processing of geospatial data. The rendering engine code language is used for calling to ensure seamless integration with the rendering engine.

[0070] In step S5, after the rendering engine completes calling of the browser executable format library of the GIS map engine, the rendering engine is compiled into a WebGL platform or a PC platform through a configured strategy to realize fusion display of BIM rendering engine and GIS map engine data.

[0071] Specifically, the rendering engine uses its own code language to call the encapsulated browser executable format library to realize the fusion and display of BIM and GIS data. The rendering engine can efficiently call the browser executable format library to realize the processing and display of GIS data and the fusion and display of BIM data on the Web. The seamless integration of the rendering engine and the browser executable format library improves the performance and user experience of the system; through the WebGL platform display, cross-platform and high-performance Web applications are realized.

[0072] The rendering engine in the application includes but is not limited to Unity or Unreal Engine, and the own code language includes but is not limited to using the rendering engine programming language, C# or C++ code to call the encapsulated browser executable format library. The rendering engine project integrated with the browser executable format library calling is compiled into the WebGL platform or the PC platform to realize the fusion and display of BIM and GIS data.

[0073] In summary, the application selects the C++ library of the GIS map engine as the source library for fusion; according to the set functions of the C++ library of the GIS map engine, the C++ library of the GIS map engine is divided into a plurality of GIS map engine C++ function libraries; the plurality of GIS map engine C++ function libraries are compiled respectively by using an open source compilation tool chain, and a plurality of browser executable format libraries meeting the requirements of running in a browser are obtained; the plurality of browser executable format libraries are subjected to interface encapsulation processing by using a readable programming language, and a plurality of browser-side libraries are obtained; the browser-side libraries are provided with a uniform interface layer; the browser executable format libraries of the GIS map engine are called by using the interface layer of the browser-side libraries through a rendering engine using a rendering engine code language, so that reading and processing of geospatial data in the GIS map engine are realized; after the rendering engine completes the calling of the browser executable format libraries of the GIS map engine, the rendering engine is compiled into a WebGL platform or a PC platform through a configured strategy, so that the fusion display of BIM rendering engine and GIS map engine data is realized. The C++ library of the GIS engine is split according to function modules, and is compiled into independent browser executable format libraries by using a compilation tool chain. The browser executable format libraries generated in this way are small in size, high in performance, easy to load and run on the Web, and solve the problem that the rendering engine cannot fuse the GIS engine on the Web. The modularized browser executable format libraries can be flexibly selected and loaded according to actual needs, improving the flexibility and expansibility of the system; unnecessary code loading is reduced, and the running efficiency is improved. The generated browser executable format libraries are provided with a uniform interface layer, which facilitates the calling of the rendering engine. The encapsulated browser executable format libraries provide easy-to-call APIs through the uniform interface layer, so that the rendering engine can conveniently access the functions of the GIS engine. The readability and ease of use of the browser executable format libraries are improved, the learning cost and development time of the developers are reduced; the encapsulated interface layer simplifies the loading and management of the browser executable format libraries. The rendering engine uses its own code language to call the encapsulated browser executable format libraries, realizes the fusion and display of BIM and GIS data, and the rendering engine can efficiently call the browser executable format libraries, realize the processing and display of GIS data, and fuse and display the BIM data on the Web. The seamless integration of the rendering engine and the browser executable format libraries improves the performance and user experience of the system; through the WebGL platform display, cross-platform and high-performance Web applications are realized. The application not only improves the performance and flexibility of the system, but also simplifies the development process, reduces the development cost, has high practical value and innovation.
