We are all aware that in some respect it’s undoubted that cultured heritage must be conserved. As an example, downtown Vienna is one of the most famous cultural sites in central Europe and most complex structures which are not easily captured with 3D mapping. One possibility to survey such an environment is new sensor equipment as a 3D laser scanner from tripod which is available and capable doing this with tremendous speed.
So we performed a test with the new RIEGL VZ-400i terrestrial laser scanner. In the night from 2nd to 3rd of June 2016 for eight working hours, one single operator has used the scanner through the city centre of Vienna. He managed to take 514 high resolution laser scans approximately every 10 meters covering various historical monuments along this path like “Stephansdom”, ”Peterskirche” and the “Hofburg” to name a few. Using the data acquired in the course of this project the authors want to show the potential of state-of-the-art terrestrial scanning to preserve very detailed 3D-information of various sites within very limited amounts of time. This paper describes the complete workflow from the one touch operation in the field up to the automatic registration process of the laser scans which were collected within this urban area.

Relevance conference | Relevance session:
This case study should show the auditorium how to select a terrestrial laser scanner in order to scan and register scan data of large historic urban sites as efficient and well-proven as possible.

The shown „high speed collection and automatic registration workflow“ for static terrestrial outdoor scans of urban areas will be published for the first time.
