Pervasive Scene Map on Wireless Devices for City Navigation

Abstract

Mobile devices equipped with GPS provide powerful tools for location-aware applications. Adding views to locations further augments users’ perception of spaces. This work creates a new type of visual map suitable for access on mobile platform. It can provide views at pervasive locations in an area. We propose a systematic approach to establish scene maps of an urban area with different types of panoramic images aligned with geospatial spaces in display. We also design comprehensive visual indexes for virtual travel and real guidance of the area on wireless devices. The extended fields of view enhance the perception of spaces on small mobile devices. Densely embedded indexes allow free transitions and exploration of the area. The resulting scene map will be an ideal digest to access spatial and dynamic information in urban environments.
