摘要：In recent years new survey technologies have been implemented in order to execute more accurate and effective measurements. In particular, the investigation of architectural goods have imposed to take into account the reconstruction of 3D models for more effective fa . ade analysis and 3D navigation. For this purpose it is necessary to derive an object digital elevation model (DEM) useful both for volume assembly and for digital orthoprojection methods. Traditionally, a DEM surveying is performed by means of profiling topographic total stations, or derived by photogrammetric stereoplotting. The aim of this paper is the first analysis of an automatic DEM surveying device capable to acquire thousands of points in few seconds with high precision and accuracy. Following the CIPA test conducted on Vienna Karlsplatz underground station designed by an art noveau master, Otto Wagner, a complete test field has been conducted. This paper presents the first result of the above mentioned device, an optical-electronic laser scanner
