[POSTER] Browsing Spatial Photography using Augmented Models

Both digital and physical 3D models of buildings as well as historical photographs of architecture are used for a wide range of needs; from research in humanities and information technologies; museum contexts and library studies; to touristic applications. Spatially oriented photographs play an important role in visualizing and browsing contemporary as well as historical architecture; starting with the ground-breaking Photo Tourism project [6]. We present a technique to combine physical 3D models of buildings with spatially registered historical photographic documents in a hand-held Augmented Reality (AR) environment. Users are enabled to spatially explore historical views of architecture by selecting photos from a collection of images which are then utilized as textures for the physical model rendered on their respective mobile device. We compare different methods to select photos registered to a physical model in hand-held AR.
