Servicing Photographs for Route Guidance in Navigation Systems

For successful route guidance, navigation systems should provide to users more realistic and actual information such as photographs than those in either 2-dimensional and 3-dimensional models. In this paper, we propose a method for servicing photographs for route guidance in navigation systems. The method includes how to acquire photographs with the most successful view for the guidance, how to construct link information among them and navigational map data, and how to provide the images to users efficiently.
