Construction method of 3D model of underground space based on multi-source data fusion
Realistic three-dimensional(3D)is a digital virtual space that reflects and expresses human production,life,and ecological space in a realistic,3D,and temporal manner.It can achieve real-time correlation and interoperability between digital space and real space,and component-level 3D models are an important part of it.As an important carrier of urban development and the foundation of urban planning and construction,the realistic 3D construction of urban underground space is essential.This article focused on the characteristics of urban underground space,analyzed the national new basic surveying and mapping pilot project in Beijing:underground space real-scene data production project of Lize Business District,and proposed a multi-source data fusion method for constructing component-level 3D models of urban underground space.The article also explored the development of urban underground space and data application scenarios,providing assistance for the widespread application of 3D data of urban underground space.
