As a result, the coloured point cloud of the
IMAGER is shown in Figure 10. The raw data
sets measured by the IMAGER and the DLR
camera are the data sets shown in Figure 3-5.
The results achieved above open a new dimen
sion with laser scanning in the cultural heritage
area.

4. CONCLUSIONS
With the developed visual laser scanner, the
control software and the software for model ge
neration, very powerful tools are available that
are suitable for most cultural heritage surveying
tasks. The developed laser scanner offers high
accuracy measurements in conjunction with a
high sampling rate and large dynamic range in
reflective properties of object surfaces (highly
reflective to absorbing). In combination with
the DLR Panoramic Colour Camera a precise
and accurate monitoring of the actual environ
ment by means of colour point clouds is
achieved. This is unique due to its high pre
cision and quality. Together with the meshing
tools implemented in LF Architect a broad
variety of cultural heritage can be semi-auto-
matically modelled.
In a next step further improvements on mapping
colour and geometry by means of raw data will
be researched with several international partners
in research projects.
ACKNOWLEDGEMENTS
Thanks to all involved institutes and companies,
and especially to the support of the "Lehrstuhl
für Steuerungs- und Regelungstechnik der TU
München” Prof. Dr.-Ing. Dr.-Ing. E.h. G.
Schmidt for the basic research years ago, an in
ternational cooperation evolved which enabled
a general application in the area of "virtual
engineering - from survey to simulation".
The authors would also like to thank Prof. Dr.-
Ing. G. Hirzinger from the DLR in Oberpfaffen
hofen for the support on this topic and the
possibility to have access to the DLR camera
for this project.
