Andreas,
we made such a project with tiles (you see what I mean, roofing tiles).
We defined a generic feature-based parametric model on Pro-eng, and it was
possible to create the geometry of a new tile, only with the description
of different functional elements. Some of these elements were some curves,
on which some basic surfaces were built. So, we introduced the capability
to scan these curves on a model and introduce them via santools module to
the parametric model.
Of course it was also possible to scan all the details of a tile, or of die
used for tile forming, and model the shapes using scantools.
We have published different results during SPIE conference in Boston, two
years ago. This project has been achieved three years ago.
We also made an industrial project for the modeling of the blade used in
the painting systems of car repare. These people need to have always the
same colors, and to keep the paintings in good conditions, before spray
painting of the cars. So they use mechanical motorised systems to mix the
paintings.
We continue working on 3D scanning and reverse engineering in my research
team. We use a Kréon line laser sensor, and different softwares for part
modelling from the scanned point clouds.
We are working on automatic generation of scanning strategy, simulation and
validation of the different related positions between the part and the sensor.
I do not know exactly what information you need.
Please let me know.
Best Regards,
Prof. A. BERNARD
