摘要：In early 2007 the special research program HiMAT – History of Mining Activities in Tyrol – was established at the University of Innsbruck. It is an interdisciplinary research project dedicated to the history of mining in Tyrol and adjacent areas, sponsored by the Austrian Science Fund (FWF). At present, the Surveying and Geoinformation Unit of University of Innsbruck is completing the modelling from a three-dimensional close-range laser scan of spectacular wooden artefacts from a Late Bronze Age ore dressing installation. In this way, the fragile objects can be saved in digital form and interpreted before undergoing the lengthy preservation process. 3D-lasercanning is a non-contact and non-destructive way of acquiring geometric data of sensitive and complex objects. The high resolution of modern equipment allows an exact spatial documentation with a high resolution texture. Compared to conventional methods the speed and the reachable degree of detail is marked higher. A known problem arising during the handling and evaluation is caused by the gigantic data volume. This needs – besides a powerful hardware and a skilful software and operator – preliminary considerations concerning the proper raster-width.The spatial models resulting from the measurement- and evaluation process can be used in different – and meanwhile often described – ways. An additional aspect arose during our pursuits with the wooden artefacts mentioned above. The findings had to be inserted into a special fluid for conservation purpose within 4 days. During the needed time span –more than a year – the findings cannot be investigated further by the archaeologists. So the virtual model can replace the fragile original which does not need to be touched further more. This method could also help to solve problems of archaeological scientists working in countries which forbid the export of archaeological artefacts. Having scanned the finds the further analysis could be done at home under more even circumstances. Finally, by an additional scanning after the conservation procedure the changes in geometry caused by the fluid can be pointed out
