The author discusses the modeling of a 3-D indoor scene from a single view using a generic object model. It is assumed that an image is made by a well-calibrated camera, and that the camera height above the floor is known. The image is assumed to be a projection of a natural corridor scene from which a generic model is known, but the specific model is unknown. This system can model any corridor that satisfies the following conditions: (1) the corridor is a rectangular parallelepiped, (2) there are several lines along each axis of the rectangle parallelepiped, (3) there are not many parallel lines in directions other than along the principal axes, and (4) corridor height is within a known range. The system for 3-D modeling from a single view of such a corridor consists of a robust bottom-up image processing part and a top-down, model-based interpretation part. Experimental results show that specific corridor models can be recovered from a single view with an approximately 1% estimation error
