Embodiment Construction

[0067] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0068] It should be understood that terms such as "having", "comprising" and "including" as used herein do not entail the presence or addition of one or more other elements or combinations thereof.

[0069] The present invention provides an indoor navigation-oriented spatial topology relationship data organization model, including:

[0070] The data organization part of the semantic elements of the indoor space of the building, which includes the floor and corridor structure, derives the vertical facility class on the basis of the indoor facilities of the building to establish the connection between the two floors and connect the floors;

[0071] The data organization part of the architectural interior space topological relationship, which is used to describe the logical stru...

Abstract

The invention discloses an indoor navigation-oriented spatial topological relation data organization model, which comprises a data organization part of building indoor spatial semantic elements, which comprises floor and corridor structures and is characterized in that a vertical facility class is derived on the basis of building indoor facilities and is used for establishing connection between two floors; and the data organization part of the building indoor space topological relation is used for describing a logic structure between the building indoor space entities and determining a relative position, designing a topological expression object corresponding to the data organization part of the building indoor space semantic elements, and expressing aggregation, adjacent and connected relations commonly existing in the building. The invention further discloses a construction method of the indoor navigation-oriented spatial topological relation data organization model. According to the method, the problem that extraction and query are difficult due to the fact that the spatial topological relation is implicitly stored in the model can be solved, the spatial query efficiency is improved, and a data organization basis can be provided for indoor emergency, indoor navigation and indoor scene display.

Description

technical field [0001] The invention belongs to the technical field of indoor navigation, and relates to an indoor navigation-oriented spatial topology relational data organization model and a construction method. Background technique [0002] With the acceleration of urbanization and the increase in the number of various types of buildings in cities, indoor navigation and location-based services (LBS) are becoming more and more important. Indoor navigation is being widely concerned by the industry and academia because of its many advantages such as making up for the limitations of outdoor map applications, having a potentially large user group, and being driven by innovative technologies and application requirements, and is gradually becoming a research hotspot. [0003] According to research, human beings spend about 90% of their time in indoor environments. In buildings, the complex indoor environment is a burden to people's cognition of indoor space. It is widely belie...
