Embodiment Construction

[0025] An algorithm for realizing indoor and outdoor cross-domain navigation functions based on indoor electronic maps, including cross-layer road network field settings, cross-layer node field settings, and cross-domain space path selection; cross-layer road network field settings include line segment start codes , line segment termination code, line segment forward length, and line segment reverse length parameter settings; field settings for cross-layer nodes include node code, node type, node name, and node floor code parameter settings.

[0026] In some implementations, its main principles involved in the calculation of parameters related to elements include the following points: planning the road network under the current area according to different area maps, abstracting it into line segments, and constructing its topological relationship, that is, adding all the road networks in the current area Line segment start and end codes, and generate codes for each node; add the...

Abstract

The invention discloses an algorithm for realizing an indoor and outdoor cross-domain navigation function based on an indoor electronic map. The algorithm comprises field setting of a cross-layer road network, field setting of cross-layer nodes and cross-domain spatial route selection, wherein the field setting of the cross-layer road network comprises parameter settings of initiative codes of line segments, terminating codes of the line segments, positive lengths of the line segments and negative lengths of the line segments. According to the technical scheme disclosed by the invention, an indoor map service system is developed and can provide a map layer, route planning and PIO (Point Of Interest) search service for a client user. A concept model of an indoor map is designed by analyzing a space structure of an indoor environment of a large-scale building; on the basis, an organization structure and a transforming process of the indoor map are optimized by combining with an access requirement of indoor map data, and a converting process from a vector map to a data map is realized; data initialization of the same building is finished by a geographic coordinate system in a storey manner. The algorithm facilitates the calling during route planning.

Description

technical field [0001] The invention relates to the field of indoor navigation, in particular to an algorithm for realizing indoor and outdoor cross-domain navigation functions based on an indoor electronic map and an implementation method for large-scale stadium areas including indoor and outdoor transitions and switching between different floors. Background technique [0002] People spend an average of 80% to 90% of their time indoors. Along with the development and construction of the city, large indoor buildings such as commercial buildings, exhibition centers, airports and museums line up one after another, and the internal structure of the buildings is becoming increasingly complex. Traditional indoor map services can no longer meet people's needs, and indoor map services emerged as the times require. People spend an average of 80% to 90% of their time indoors. Along with the development and construction of the city, large indoor buildings such as commercial building...
