Description

Technical Field

[0001] The present invention relates to the technical field of building information fusion, and in particular to a method and device supporting multi-terminal BIM and GIS fusion. Background Art

[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, the combination of BIM and GIS, through the display and interaction of the Web terminal, can greatly improve the efficiency and effectiveness of building information management and urban planning.

[0003] At present, the existing technology realizes the integration of BIM and GIS on the Web side, adopts the open source WebGL graphics engine and the open source GIS global map Web class library to realize the integration of BIM and GIS on the Web side. Under this technical solution, the graphics engine and the GIS engine are integrated by superimposing on the web page. The existing technology usually uses the WebGL graphics engine (such as three.js) on the Web side to realize the rendering of BIM objects. The display effect of the WebGL graphics engine on the Web side is relatively general, which is quite different from the actual model of the physical world. The rendering engine is used on the PC side to render BIM objects, but because the map engine cannot be cross-platform, the integration of BIM and GIS cannot be realized on the Web side. 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 technical solution for the non-Web side of the rendering engine, so it can only realize the integration of BIM and GIS on the non-Web side. If the existing technical solution is adopted, the overlay display is still performed on the Web page, and the development is carried out using the Web-side JavaScript library of the rendering engine and the JavaScript library of the GIS engine. The development complexity under this technical solution is relatively large, and the development project cannot be flexible and portable and reusable, and cannot achieve deep integration of BIM and GIS.

[0004] Therefore, how to invent a method for integrating BIM and GIS to solve the problem that the existing BIM and GIS integration on the Web side has poor display effect and that the BIM and GIS integration on the PC side cannot be applied across platforms has become an urgent problem to be solved.

[0045] The following is a description of the implementation of the present invention by specific embodiments. People familiar with the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] Example 1

[0047] See also Figure 1 Embodiment 1 of the present invention provides a method for supporting multi-terminal BIM and GIS integration, comprising the following steps:

[0048] S1. Select the C++ library of the GIS map engine as the fusion source library; divide the C++ library of the GIS map engine into several GIS map engine C++ function libraries according to the set functions of the C++ library of the GIS map engine;

[0049] S2. Compile several GIS map engine C++ function libraries respectively through an open source compilation tool chain to obtain several browser executable format libraries that meet the requirements for running in the browser;

[0050] S3, performing interface encapsulation processing on a plurality of the 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 through a rendering engine, and using the interface layer of the browser-side library to call the browser executable format library of the GIS map engine, so as to realize reading and processing of geographic spatial data in the GIS map engine;

[0052] S5. After the rendering engine completes the call to the browser executable format library of the GIS map engine, the rendering engine is compiled into a WebGL platform or a PC platform through the configured strategy to realize the integrated display of the BIM rendering engine and the GIS map engine data.

[0053] In this embodiment, in step S1, the C++ library of the GIS map engine is selected as the fusion source library; according to the set function 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 base of GIS map engine is generally divided into C++ library, game engine library and Web library for external use. In order to realize the deep application of the underlying interface of GIS map engine and perform deep integration from the bottom layer, C++ library is selected as the source library for integration.

[0055] In practical applications, a complete GIS map engine C++ library is often multifunctional and bulky. In some specific BIM and GIS fusion scenarios, only part of the GIS engine's functions may need to be used. In order to improve the flexibility and lightweight of the system, the present invention proposes a method for split compilation for the GIS map engine, which splits and compiles the C++ library of the GIS map to form multiple browser executable format libraries for use by the rendering engine. The rendering engine can call the browser executable format library of the GIS engine as needed to achieve flexibility and lightweight. Analyze the GIS map engine 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, several GIS map engine C++ function libraries are compiled respectively through an open source compilation tool chain to obtain several browser executable format libraries that meet the requirements of running in the browser;

[0057] For details, see Figure 2 The browser executable format compilation tool chain is used to compile the C++ code of each functional module separately to generate an independent browser executable format library. 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 library to reduce the size of the browser executable format library.

[0058] like Figure 3 As shown, the specific compilation steps are:

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

[0060] S22. Install a tool chain for compiling files in a format that can be run in the browser;

[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, compile 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 through the compilation tool chain, and convert the C++ function library of the GIS map engine into the browser executable format library.

[0064] The present invention realizes the flexibility and lightness of the GIS map engine. The rendering engine can load and call the browser executable format library of each functional module as needed, thereby reducing system resource occupation and improving operation efficiency.

[0065] In this embodiment, in step S3, several browser executable format libraries are subjected to interface encapsulation processing by a readable programming language to obtain several 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, its readability is poor. Considering improving the readability of the browser executable format library and facilitating development and application, the present invention proposes 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] like Figure 4 As shown, the generated browser executable format library is encapsulated in a readable programming language, providing a browser executable format library with a highly readable and easy-to-use interface. This interface enables the loading and calling of the browser executable format library, and provides an easy-to-use access interface to the outside world, so that the rendering engine can use its own programming language to schedule and call.

[0068] In this embodiment, in step S4, the rendering engine uses the rendering engine code language and uses the interface layer of the browser-side library to call the browser executable format library of the GIS map engine to realize the reading and processing of the geographic spatial data in the GIS map engine;

[0069] Specifically, Figure 5 As shown, 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 the reading and processing of geographic spatial data. The rendering engine code language is used for calling to ensure seamless integration with the rendering engine.

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

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

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

[0073] In summary, the present invention selects the C++ library of the GIS map engine as the fusion source library; divides the C++ library of the GIS map engine into several GIS map engine C++ function libraries according to the set function of the C++ library of the GIS map engine; compiles several of the GIS map engine C++ function libraries respectively through the open source compilation tool chain to obtain several browser executable format libraries that meet the requirements of running in the browser; performs interface encapsulation processing on several of the browser executable format libraries through a readable programming language to obtain several browser-side libraries; the browser-side library is provided with a unified interface layer; uses the rendering engine code language through the rendering engine, and uses the interface layer of the browser-side library to call the browser executable format library of the GIS map engine to realize the reading and processing of geographic spatial data in the GIS map engine; after the rendering engine completes the call to the browser executable format library of the GIS map engine, the rendering engine is compiled into a WebGL platform or a PC platform through the configured strategy to realize the fusion display of the BIM rendering engine and the GIS map engine data. The present invention splits the C++ library of the GIS engine according to functional modules, and compiles it into an independent browser executable format library using a compilation tool chain. The browser executable format library generated in this way is small in size and high in performance, and is easy to load and run on the Web side. At the same time, it solves the problem that the rendering engine cannot integrate the GIS engine on the Web side. The modular browser executable format library can be flexibly selected and loaded according to actual needs, which improves the flexibility and scalability of the system; reduces unnecessary code loading and improves operation efficiency. The generated browser executable format library provides a unified interface layer for easy calling by the rendering engine. The encapsulated browser executable format library provides an easy-to-call API through the unified interface layer, so that the rendering engine can easily access the functions of the GIS engine. The readability and ease of use of the browser executable format library are improved, and the learning cost and development time of developers are reduced; the encapsulated interface layer simplifies the loading and management of the browser executable format library. The rendering engine uses its own code language to call the encapsulated browser executable format library to realize the integration 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 integrate with BIM data to display on the Web side. The seamless integration of the rendering engine and the browser executable format library improves the system performance and user experience; through the WebGL platform display, cross-platform, high-performance Web applications are realized. The present invention not only improves the performance and flexibility of the system, but also simplifies the development process and reduces the development cost, and has high practical value and innovation.
