Abstract
Different types of maps have specific, limited functions, and to satisfy user requirements under various situations, combinations of types are required. With the development and popularization of mapping applications on mobile devices, efforts have been made to integrate analogue maps with location-based services (LBSs). Previous work in this area has mainly used points as georeferences to calculate positions on map images, but point-based geocoding does not achieve accurate and stable positioning results. This paper introduces a map signboard collage system (MSCS) to enable LBSs using copied images of multiple map signboards on smartphones. The system uses polylines as georeferences, improving the accuracy and stability of positioning results, and supports automatic egocentralization of map images with compass sensors in smartphones. In addition, it collages multiple maps to allow natural, smooth and dynamic map switching for inter-map navigation.
