Abstract for malis_eccv00

European Conference on Computer Vision, 2000.

In this paper we describe an efficient method to impose the constraints existing between the collineations which can be computed from a sequence of views of a planar structure. These constraints are usually not taken into account by multi-view techniques in order not to increase the computational complexity of the algorithms. However, imposing the constraints is very useful since it allows a reduction in the geometric errors in the reprojected features and provides a consistent set of collineations which can be used for several applications such as mosaicing, reconstruction and self-calibration. In order to show the validity of our approach, this paper focus on self-calibration from unknown planar structures proposing a new method exploiting the consistent set of collineations. Our method can deal with an arbitrary number of views and an arbitrary number of planes and varying camera internal parameters. However, for simplicity this paper will only discuss the case with constant camera internal parameters. The results obtained with synthetic and real data are very accurate and stable even when using only a few images.

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.
