Geometric modelling of a large dam by terrestrial laser scanning
Alba, Mario ... [et al.]
This paper presents an experience of terrestrial laser scanning surveying of a large dam located in Alta Valtellina (Italy) at the Cancano Lake. The handler of this plant (AEM S.p.A., Milan) has requested this activity to produce some drawings of it which was built up during 50 and to construct a 3D model to be used as geometric basis for the finite-element modelling of static and dinamic structural behaviour. In the paper all stages of the process for data acquisition are described; in particular, large enphasis is given to the information extraction stage needed for the setup of final documents. Moreover, some notes about a method to compute the accuracy of surface points which have been measured by terrestrial laser scanning are reported.
