results in a general cone.
data acquisition. Therefore the model of the statue
has holes, which cannot be closed without any further
measurements. These holes and additionally random and
gross errors in the laser scanner data generate problems
during the automatic modelling process (cf. Sec. 4).
Nevertheless we were able to determine a smooth surface
model of the statue. Improvements of this model would
be possible with the help of additional image information.
With the help of this additional data further geometric
details of the sensed object can be modelled. The goal for
further research work in the area of 3D-modelling will be
the development of adequate methods for the combined
surface determination of laserscanner data and image
data.
