In the future, a virtual twin of the Chemnitz Opera House will allow avatars access, who will enjoy the right perspective and spatial sound from every seat.
An evening at the opera promises more than musical enjoyment and stage design, it is also a social event. The social presence of other people is an essential part of this. A team under the project coordination of Frank Dittrich, Professor of Ergonomics and Innovation Management at Chemnitz University of Technology, has now created a virtual twin of the Chemnitz Opera House and in particular the hall.
The researchers used various techniques, such as photogrammetry. A semi-automated 3D model is created from numerous photos, some of which were also taken by drones. At the same time, 360-degree recordings were used, as well as stationary laser scanning and mobile LiDAR sensors, each of which scanned the surroundings with distance measurements.

Cooperation of several research institutes
In further steps of the SocialSTAGE-VR project, the partners involved want to expand the most realistic possible 3D model of the event space into an immersive event environment for online visitors with VR glasses and headphones. For example, technicians from the project partner, Die Etage GmbH from Osnabrück, recorded concerts with stereoscopic camera systems. This enables the virtual visitor to see the artists on stage from the right perspective from their seat.

The Fraunhofer Institute for Integrated Circuits in Erlangen contributes sound libraries for the sound. The aim is for the opera-goer’s listening experience to ring out from the expected direction. In addition, other partners are working on the integration of individualized avatars, which can even exchange information with each other. Studies with subjects at Chemnitz University of Technology will soon show how immersive the participants perceive their virtual opera visit.
