Abstract

The invention provides an indoor floor-spanning path planning method and an indoor floor-spanning path planning device. The method comprises the following steps: acquiring indoor GIS (Geographic Information System) map data, and generating multilayer road network data and vertical communication data among floors; receiving a starting point and an ending point inputted by a user; judging whether the starting point and the ending point are at the same floor or not; if not, selecting a vertical communication facility meeting a preset optimized condition, a path L1 between the starting point and the vertical communication facility and a path L2 between the vertical communication facility and the ending point from the vertical communication data among the floors and the multilayer road network data; connecting the L1, a channel L3 formed by the vertical communication facility and the L2 to obtain a path planning between the starting point and the ending point. According to the indoor floor-spanning path planning method and the indoor floor-spanning path planning device disclosed by the invention, the path planning of all the floors is realized on the basis of a method for analyzing layer by layer, and the path planning among floor-spanning position points is realized by using connection information among the floors.

Description

technical field [0001] The present application relates to the technical field of GIS application, in particular, to an indoor cross-floor path planning method and device. Background technique [0002] With the development of geographic information system (GIS, Geographic Information System) technology, the application field of location service has also expanded from traditional outdoor space to indoor space. Indoor route planning is a research and application hotspot of indoor location-based services. It can combine indoor positioning technology and mobile communication technology to realize indoor real-time dynamic navigation and support applications such as indoor public safety, emergency rescue, business intelligence and public services. For example, users in complex indoor buildings such as large department stores and airports can use precise positioning technology to determine their own location, and based on indoor map data, generate road network information to achieve...
