This paper presents a model-based photo registration system for the creation and visualization of environmental content. We utilize freely available Digital Terrain Models of the planet, such as those provided by NASA, to generate a three-dimensional synthetic model around a viewer’s location. Using an array of image processing algorithms we then align photographs to this model. We will demonstrate the precision of the resulting system through the overlaying of Internet content (such as mountain names and GPS tracks), into geo-referenced photos. Additionally, we will show how a metric can be derived for photos that describes not only which mountains can be seen, but also how visible they are.

Abstract
This paper presents a model-based photo registration system for the creation and visualization of environmental content. We utilize freely available Digital Terrain Models of the planet, such as those provided by NASA, to generate a three-dimensional synthetic model around a viewer’s location. Using an array of image processing algorithms we then align photographs to this model. We will demonstrate the precision of the resulting system through the overlaying of Internet content (such as mountain names and GPS tracks), into geo-referenced photos. Additionally, we will show how a metric can be derived for photos that describes not only which mountains can be seen, but also how visible they are.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
