This paper proposes a vision-based navigation system for Tamsui historical buildings. Most travelers in Tamsui take a picture of the historical buildings by using their mobile phone's camera. Our system is designed to automatically extract the color and edge features out of images, and then search similar images from an image database by comparing with these features. For the searched buildings, their contextual navigation and 3D model will be displayed or projected in a screen. This makes the navigation process easier and more interesting. Experimental results showed that the proposed scheme retrieves the target building images effectively and accurately.
