摘要：In this paper the comparative application of two terrestrial 3D laser scanning systems for recording and modelling of two historical halls in the City Hall Hamburg is presented. The two halls (Kaisersaal and Gro.er Festsaal) were scanned in approximately three hours with the Mensi GS100 from Trimble and with the IMAGER 5003 of Zoller & Fr.hlich from five (GS100) and 22 stations (IMAGER 5003), in order to generate different cuttings, 2D plans and 3D models from each entire point cloud. For the geo- referencing of the point clouds into a local coordinate system a precision of approx. 5 mm (GS100) and 8 mm (IMAGER) was achieved using specific targets. The quality of the digital CAD data modelled from the laser scanner data is controlled by reference distances, while the efficiency of the recording and data processing was compared to each other and finally evaluated
