Floor-plan reconstruction from panoramic images

The capturing of panoramic 360° images has become a popular photographic technique. While a panoramic image gives an impressive view of the environment, many people have difficulties to understand the spatial scene arrangement from this flat image. In this paper, we present a new visualization technique for panoramic images based on a coarse reconstruction of the indoor environment, in which the panorama was captured. Applications of this are, for example, real-estate or hotel advertising, featuring virtual tours through the apartment. We use a semi-automatic reconstruction process, in which the user marks the room corners in the panoramic images. These can be translated into viewing-angle measurements, from which our algorithms can compute the exact sizes of the walls, based on a pre-defined geometric model.
