Resumo: | |||||||||||||||||||||||||||||||||||||||||
The calibration of multiple cameras is an important step in the installation
of optical tracking systems. The accuracy of a tracking system is directly related
to the quality of the calibration process. Several calibration methods have been
proposed in the literature in conjunction with the use of artifacts, called
calibration patterns. These patterns, with shape and size known, allow the
capture of reference points to compute camera parameters. To yield good results
these points must be uniformly distributed over the tracking area. The
determination of the reference points in the image is an expensive process prone
to errors. The use of a good calibration pattern can reduce these problems. This
thesis proposes a new multiple camera calibration method that is efficient and
yields better results than previously proposed methods available in the
literature. Our method also proposes the use of a new simple calibration pattern
based on perspective invariant properties and useful geometric properties. This
pattern yields robust reference point identification and more precise tracking.
This thesis also revisits the multiple calibration process and suggests a
framework to compare the existing methods including the one proposed here.
This framework is used to produce a flexible implementation that allows a
numerical evaluation that demonstrates the benefits of the proposed method.
Finally the thesis presents some conclusions and suggestions for further work.
