Virtual Reality Labor (VR-Lab)

In the Virtual Reality Laboratory (VR-Lab), methods and concepts for a digital inspection of buildings and planning-oriented tools are created, supported by Virtual Reality (VR) and Augmented Reality (AR) technologies. The core equipment of the VR Lab includes VR and AR glasses, gesture-controlled touch tables and a VR wall. In addition, the laboratory is equipped with a VR treadmill, through which innovative possibilities for movement in VR can be examined. With the help of newly emerging VR technologies, such as the HTC-VIVE or the Hololens, BIM-based approaches are processed immersively and interactively and integrated into research projects. The technological progress of recent memory makes it possible to develop completely new ways of working for a BIM-based way of working in construction. For example, topics such as the virtual planning of barriers for occupational safety, virtual inspection of a tunnel boring machine (TBM) or collaborative and interactive modeling of lines in tunnel construction have already been developed in the context of projects in the VR laboratory. The general activities in the VR-Lab therefore include the preparation of model-based content and the development of interaction methods.

EQUIPMENT

In the virtual reality laboratory of the Chair of Computer Science in Civil Engineering, a so-called VR wall is available for stereoscopic display. 3D models and images with depth information can be viewed in a resolution of 2560x1600 pixels on a screen of 3.5 x 2.2 meters. Four projectors are used, which project four overlapping image areas onto a special screen. The stereoscopic display is based on active shutter glasses, in which an image is displayed alternately for each eye of the viewer at a refresh rate of 60 Hz. For interaction with the virtual world, a flystick is used in combination with an optical tracking system, in which infrared cameras permanently monitor the position of the flystick by means of markings on the flystick, allowing the user to move freely in space. Optical tracking systems can also be used to capture tools and entire human models to manipulate them in real time.

Spot von Boston Dynamics

Unser Spot heißt RUBy. Aktuell wird sie trainiert eine exakte Indoor-Lokalisierung durchzuführen und darauf aufbauend sich in den "eigenen vier Wänden" autonom zu bewegen.

Weitere technische Informationen: L/B/H(walk): 110/50/61 cm; Gewicht mit Batterie: 31,7 kg; Geschwindigkeit: 1,6 m/s; Einsatzdauer pro Batterieladung: etwa 90 min; 5 Kameras; FOV (overall field of view): 360°;

BLK2Go von Leica

Mit dem mobilen Lasercanner BLK2Go von Leica lassen sich schnell, einfach und unkompliziert Punktwolken aufnehmen. Mit seinen 775 Gramm und den 50 Minuten Akkulaufzeit lässt sich eine Vielzahl an Aufnhamen vornehmen.

Weitere technische Informationen: LiDAR Reichwete von 25 m, vollständig colorierte 3D Punktwolken, Grandslam, Wireless und USB 3.0, 360° Aufnahmen, 12 Mpixel

RTC360 von Leica

Der mobile Laserscanner RTC360 braucht nur <2 Minutem um einen Fulldome-Scan aufzunehmen. Bei der Aufnahme von Punktwoken erfolgt das automatische Entfernen von sich bewegenden Objekten - so wird nur das gescannt was gescannt werden soll.

Weitere technische Daten: 360° effektiver Messbereich, Messreichweite von 05, - 130 m, integriertes WLAN, App-Steuerung, 5,35 kg, 4 Stunden Akkulaufzeit, 3-Kamerasystem mit 36 mpixel
