Description

The Virtual Reality Lab – the so called CAVE – is an immersive, interactive 3D test environment.
The projection consists of seven elements. Each element has a width of 1.52 m and a height of 2.03 m. In addition, a 40 cm base. The overall projection is thus an area of ​​21.6 square meters.
To give an spatially impression the projection is stereoscopic. Each of the five elements is illuminated by two projectors. A projector generates the image for the right and the other the image for the left eye. For the separation of the images linear polarization filters are used, mounted on the projectors. The viewer gets a pair of glasses with two different polarized glasses, so that he sees a 3D image with depth information.

The Vritual Reality Lab was originally constructed within the project Virtual Crater. The goal of this project between the 1st of Mai 2009 and the 31st of August 2012 was to develop a virtual test environment (virtual testbed) where it is possible to program, test, and optimize robot systems in a realistically simulated lunar crater in a cost-effective way.
The Virtual Crater is a comprehensive simulation environment that makes it possible to program and test missions of lunar surface exploration and to demonstrate new concepts.
