Modelling of building interiors with mobile phone sensor data
Creating as-built plans of building interiors is a challenging task. In this paper we present a semi-automatic modelling system for creating residential building interior plans and their integration with existing map data to produce building models. Taking a set of imprecise measurements made with an interactive mobile phone room mapping application, the system performs spatial adjustments in accordance with soft and hard constraints imposed on the building plan geometry. The approach uses an optimisation model that exploits a high accuracy building outline, such as can be found in topographic map data, and the building topology to improve the quality of interior measurements and generate a standardised output. We test our system on building plans of five residential homes. Our evaluation shows that the approach enables construction of accurate interior plans from imprecise measurements. The experiments report an average accuracy of 0.24 m, close to the 0.20 m recommended by the CityGML LoD4 specificatio
Dynamic navigation indoor map using Wi-Fi fingerprinting mobile technology
This paper presents the exploitation of Wi-Fi signals sensors using
fingerprinting method to capture the location and provide the possible
navigation paths. Such approach is practical because current smartphones
nowadays are equipped with inertial sensors that can capture the Wi-Fi
signals from the Wi-Fi’s access points inside the building. From
the comparative study conducted, the AnyPlace development tool is used for
the development of dynamic navigation indoor map. Its components, namely;
Architect, Viewer, Navigator and Logger are used for different specific
functions. As a case study, we implement the proposed approach to guide
user for navigation in Sunway Pyramid Shopping Mall, Malaysia as floor
plan as well as using Google Maps as the base map for prove of concept.
From the developer point of view, it is observed that the proposed approach
is viable to create a dynamic navigation indoor map provided that the floor
plans must be generated first. Such plan should be integrated with the SDK
tool to work with the navigation APIs. It is hoped that the proposed work can
be extended for more complex indoor map for better implementatio
