This paper describes a system which automatically derives 3D models of architectural scenes from multiple images. This system differs from previous structure from motion algorithms in that it explicitly makes use of strong geometric constraints such as perpendicularity and verticality which are likely to be found in architecture. Structure is compactly represented as a piecewise planar model which is initialised automatically by segmenting a feature-based reconstruction. An efficient technique for evaluation of model likelihood is also presented, which allows a rapid search through a large number of 3D models.

If you have difficulty viewing files that end '.gz', which are gzip compressed, then you may be able to find tools to uncompress them at the gzip web site.

If you have difficulty viewing files that are in PostScript, (ending '.ps' or '.ps.gz'), then you may be able to find tools to view them at the gsview web site.

We have attempted to provide automatically generated PDF copies of documents for which only PostScript versions have previously been available. These are clearly marked in the database - due to the nature of the automatic conversion process, they are likely to be badly aliased when viewed at default resolution on screen by acroread.
