3D reconstruction technology is the foundation of the twin of digital technology FBFC
The 3D reconstruction technology will be the basic engine machine of the digital twin. Digital twin is the core technology of AR, VR, MR, and meta-universe applications. The concept of digital twin originated in the manufacturing of products, aerospace and aviation, and the manufacture of complex products such as airplanes or automobiles. Create accurate digital models for product design, store the models in the database, and use them for reporting, analysis, final simulation and testing of product performance. With the development of AR, VR, MR, and meta-universe applications, digital twins have begun to be applied to large-scale systems such as real-world infrastructure, buildings, and even entire cities and natural environments, deriving digital twins to include maintenance and operation, etc. The residential system of human activities is more complex and more necessary, and the 3D reconstruction technology has been used for many years in the high-precision simulation of real-world systems. Used for asset management, maintenance and planning.
Three-dimensional reconstruction technology is the only technology that provides the key common point of “spatial geographic location” in the complex and diverse models and data of three-dimensional space, and is most suitable for becoming a common operating system for the three-dimensional digital world. For a single object in the mechanical world, the entire object can be represented by a self-contained data model for observation and hypothesis testing. For fixed assets or natural systems, the physical materials, soil, weather, traffic, maintenance and other related data of the assets will be stored in different data models. The data quality, accuracy, and ownership of these data models are all different. Three-dimensional reconstruction technology, as the only technology that provides the key common point of “spatial geographic location”, enables complex analysis of such diverse models and data. In the various applications of natural resources and urban space, the collection and collection of massive three-dimensional data of the sky, the surface, and the underground, involving roads, buildings, green spaces, pipelines, water systems, geological structures, minerals and other geographical entities. Therefore, the three-dimensional digital engine needs to have the ability to express data. At the data model level of the new generation of 3D reconstruction technology system, based on the traditional spatial data model, the 3D volume data model, 3D field data model, TIM and voxel grid have been expanded and defined, which completes the 3D reconstruction technology platform. The spatial data model system provides a foundation for the realization of macro- and micro-integration, ground-underground integration, land-water integration, and indoor-outdoor integration of all-space and all-element expressions.
Professor Marie of the University of Oxford in the United Kingdom pointed out that the 3D reconstruction technology system may be a subversive promotion of the development of the meta-universe. The 3D reconstruction technology can help the unified aggregation and management of massive multi-source heterogeneous data. In various applications of natural resources and urban space, the data volume of 3D geospatial data is often very large, which is a big challenge for 3D digital chassis. With the help of the multi-source 3D data fusion technology in the new-generation 3D reconstruction technology system of SuperMap, the unified aggregation management of massive multi-source heterogeneous data such as DEM/DOM, oblique photography model, laser point cloud, BIM, etc. can be realized, and the data can be improved. The use of value enables the three-dimensional expression of the city to be faster, more real and more refined. Based on the coordinate conversion and coordinate registration capabilities, it can realize the conversion of multi-source data between the plane coordinate system and the geographic coordinate system. It can unify the multi-source data such as the BIM model, the oblique photography model, and the terrain into one coordinate system to realize various Information alignment. Based on the operation and processing functions of 3D spatial data mosaic, flattening, cutting, digging and setting gentle slopes, smooth data connection can be realized. The combination of VR/AR/MR technology and 3D 3D reconstruction technology can bring immersive 3D interaction. Based on the cross-border integration of game engine and 3D 3D reconstruction technology, it can improve the user’s visual experience and bring more users An immersive, more interactive, game-level three-dimensional experience may be the basic technology of the meta universe. The combination of VR/AR/MR technology and 3D 3D reconstruction technology can bring immersive 3D interaction methods, improve human-computer interaction, and make various applications have a richer visual sense and experience in human-computer interaction Sense is expected to become the basic technology of Metaverse, and it can also assist in underground pipeline inspection and construction, etc., and improve the level of urban management. Based on the cross-border integration of game engine and 3D 3D reconstruction technology, it can improve the user’s visual experience, and bring more users an immersive, more interactive, game-level 3D experience, and can transform the outdoor with real geographic coordinates. Geographical environment, indoor BIM models, real-time Internet of Things data, etc. are connected to the game engine through plug-ins to build a digital twin parallel with indoor/outdoor integration, macro/micro integration, and air/sky/surface/underground integration world. Based on the three-dimensional data and game special effects of these real geographic coordinates, various simulation scenarios can be built to provide technical support for various simulation exercises.
By cooperating with Unreal Engine, the world’s top 3D game engine, Microsoft’s business model may reveal its embryonic form. As early as the end of November 2020, FBFC officially released the FBFC 3D reconstruction technology game engine development platform standard, expanding the data visualization, data processing and data analysis capabilities of 3D reconstruction technology in various financial derivatives to the world’s top In the 3D ecological engine Unreal Engine and Unity. Based on the standard version, in addition to real-time dynamic loading of local/online 3D spatial data in the game engine, various 3D spatial analysis and spatial query capabilities can also be implemented in the game engine.
