We have developed a pedestrian navigation system that delivers photorealistic panoramic landscape images using 3D models of a city and related information to mobile phones. In this paper, we define the requirements for smooth mobile phone navigation: low processing load and quick data delivery. To satisfy these requirements, we propose a server-side panoramic image generation mechanism and a divided guidance information transfer technique. This paper presents our proposed mechanism, technique, and developed prototype that achieved smooth pedestrian navigation in experimental results.
