Abstract
Abstract. 3D models are more powerful than 2D maps for indoor navigation in a complicate space like Hubei Provincial Museum because they can provide accurate descriptions of locations of indoor objects (e.g., doors, windows, tables) and context information of these objects. In addition, the 3D model is the preferred navigation environment by the user according to the survey. Therefore a 3D model based indoor navigation system is developed for Hubei Provincial Museum to guide the visitors of museum. The system consists of three layers: application, web service and navigation, which is built to support localization, navigation and visualization functions of the system. There are three main strengths of this system: it stores all data needed in one database and processes most calculations on the webserver which make the mobile client very lightweight, the network used for navigation is extracted semi-automatically and renewable, the graphic user interface (GUI), which is based on a game engine, has high performance of visualizing 3D model on a mobile display.
Highlights
Built environment is an important factor in people's daily life as they spend most of their time indoors
A successful implementation of the proposed system would provide visitors of Hubei Provincial Museum with their current locations displayed in a 3D model of the museum on their mobile device and the shortest route when searching for an object of interest
This research project has clearly demonstrated that the proposed 3D model is valuable for indoor navigation since it can describe the location in object-level, provide context information of spatial objects, and more importantly offer a very realistic navigation environment as well as a good overview of it
Summary
Built environment is an important factor in people's daily life as they spend most of their time indoors. Most indoor navigation systems such as Google map (Google, n.d.), Wifarer (Wifarer Indoor Positioning, n.d.) and BuildNGO (Android Apps on Google Play, n.d.) use 2D maps to represent the environment. These maps do not provide adequate information about object features, such as 3D shape, colours and textures. A successful implementation of the proposed system would provide visitors of Hubei Provincial Museum with their current locations displayed in a 3D model of the museum on their mobile device and the shortest route when searching for an object of interest (e.g., exhibit, exit or restroom).
