  annote = { We investigate a strategy for reconstructing of buildings
    from multiple (uncalibrated) images. In a similar manner to the
    Facade approach we first generate a coarse piecewise planar model
    of the principal scene planes and their delineations, and then use
    these facets to guide the search for indentations and protrusions
    such as windows and doors. However, unlike the Facade approach
    which involves manual selection and alignment of the geometric
    primitives, the strategy here is fully automatic.

    There are several points of novelty: first we demonstrate that the
    use of quite generic models together with particular scene
    constraints (the availability of several principal directions) is
    sufficiently powerful to enable successful reconstruction of the
    targeted scenes. Second, we develop and refine a technique for
    piecewise planar model fitting involving sweeping polygonal
    primitives, and assess the performance of this technique. Third,
    lines at infinity are constructed from image correspondences and
    used to sweep planes in the principal directions.

    The strategy is illustrated on several image triplets of College
    buildings. It is demonstrated that convincing texture mapped
    models are generated which include the main walls and roofs,
    together with inset windows and also protruding (dormer) roof
    windows.  },
