Abstract
Embodiments relate to modeling three-dimensional interiors from photographic images. In a first embodiment, a computer-implemented method creates a three-dimensional model of an interior of a building from a photographic image. Input data is received from a user specifying a floor plan of the interior of the building. A first constraint input by a user indicating that a position on the floor plan corresponds to a position on the three-dimensional model is received. A second constraint input by a user indicating that a position on a photographic image of the interior corresponds to a position on the three-dimensional model is received. Finally, the three-dimensional model and camera parameters representing a camera that took the photographic image of the interior are altered based on the first and second constraints.
