Localization and building identification in outdoor environment for smartphone using integrated GPS and camera

In this study, we aim at studying for an inexpensive-but-effective real-time localization and identification of known buildings or large permanent structures within user´s current position in outdoor environment using integrated GPS and camera on smartphone. In addition to this, we also provide users guidance by augmenting text information describing about detected building over live image on display. A prototype application of this proposed approach could be used for guiding tourists at tourist sites as well as general users at any unfamiliar areas. The problem is solved using GPS for initial location estimation. Then the result is refined using visual identification technique. Experiments show that the proposed method could localize the user´s position and identify nearby, known buildings in real-time.
