Research on Digitalization of Non-Exposed Space

Abstract

Non-exposed space is defined relative to exposed space, and mostly refers to indoor or semi-indoor scenes, such as urban rail transit, tunnels, coal mines, factories, shopping malls, hospitals, etc. Navigation and location information are closely related to human production and life. No matter in exposed or non-exposed spaces, it is increasingly urgent to obtain location information of mobile terminals quickly and accurately and to provide navigation and location services. Therefore, it is necessary to use the spatial digital technology to complete the three-dimensional visualization modeling of the spatial structure, buildings and facilities of the non-exposed space using a unified spatial coordinate system and BIM technology, so as to realize the spatio-temporal integration of the non-exposed space and the exposed space. Data twinning and structural perspective, complete the smooth transition of business applications in the two spaces, and enhance people’s sense of comfort and security in non-exposed spaces. This paper will build the structure of the digitalization of non-exposed spaces, discuss the key technologies, and analyze people’s needs for non-exposed spaces.
