Abstract
Accurate and fast indoor Location-Based Services (LBS) is very important for daily life and emergency response. Indoor map is the basis of indoor LBS. The model construction and data organization of indoor map are the key scientific problems that urgently need to be solved in the current indoor LBS application. In recent years, hybrid models have been used widely in the research of indoor map, because they can balance the limitations of single models. However, the current studies about hybrid model pay more attention to the model accuracy and modeling algorithm, while ignoring its relationship between positioning and navigation and its practicality in mobile indoor LBS applications. This paper addresses a new indoor map model, named Building Information Modeling based Positioning and Navigation (BIMPN), which is based on the entity model and the network model. The highlight of BIMPN is that it proposes a concept of Step Node (SN) to assist indoor positioning and navigation function. We developed the Mobile Indoor Positioning and Navigation System (MIPNS) to verify the practicability of BIMPN. Results indicate that the BIMPN can effectively organize the characteristics of indoor spaces and the building features, and assist indoor positioning and navigation. The BIMPN proposed in this paper can be used for the construction of indoor maps and it is suitable for mobile indoor positioning and navigation systems.
Highlights
With the rise of mobile Internet and the wide application of location services, people’s need for navigation has increased, especially when they are in an unfamiliar and complex indoor environment, such as the library [1], shopping malls [2], and hospital [3]
Based on the above analysis and technical investigations, this paper presents a 3D indoor hybrid building map model, named Building Information Modeling based Positioning and Navigation (BIMPN) for mobile indoor navigation systems
In order to verify the usability of the method in the mobile indoor positioning navigation application, we develop the Mobile Indoor Positioning and Navigation System (MIPNS) and design two different scenario cases
Summary
With the rise of mobile Internet and the wide application of location services, people’s need for navigation has increased, especially when they are in an unfamiliar and complex indoor environment, such as the library [1], shopping malls [2], and hospital [3]. The markers and context information in indoor map can be used to correct indoor positioning errors and plan indoor navigation paths [8,9]. The existing indoor map technology is still in a relatively immature state. It has some problems such as a single model application scenario and incomplete coverage of element information, so it cannot adapt to the challenges of complex building indoor environments and diversified indoor applications. The indoor map cannot be maximally used in the indoor LBS
