Laboratory description
The Photogrammetry, Imaging & eXperience Lab (PIXEL) comprises two laboratory rooms and is equipped for automated interpretation and measurement in aerial photographs, satellite and close-range images. This equipment is one of the leaders in the field of digital photogrammetry in the German university landscape. The laboratory provides services for 4 courses of study of Faculty C, for research projects and external events of the university.
Hardware
Hardware
In terms of computer equipment, a total of 22 stereo-capable PCs are available, all of which are equipped for photogrammetry and remote sensing tasks.
All workstations are equipped with active LCD stereo viewing and each with an additional at least 19" TFT screen. Each of these stations is equipped with Matlab, AutoCAD and MS Office packages.
For visualisation purposes, a stereo beamer CUBE 3D from Digital Image with a fixed screen (room 2/222) and a portable screen is available. It is used for lectures and exercises as well as for 3D visualisations and animations of various kinds. The observation is done passively with polarization glasses.
In addition, a large number of external USB drives with up to 1TByte storage capacity each are available in the laboratory. A Tablet PC is available for the instructor to supervise exercises. The laboratory has a whiteboard for exercises, meetings and lectures in combination with practical exercises.

Other equipment
Other equipment
A digital reflex camera (Canon), two panorama heads, a UAV PAMS from Germatics GmbH for aerial photography and a Tritop HD industrial measuring system are available for photogrammetric recordings.
2 Festo Robotino Premium research robots were procured in the HFT strategy project "Indoor Navigation and Mapping" and have already been used in teaching. The robots are equipped with 2 Bumblebee stereo cameras, 2 Xsens IMUs, 2Kincect 2.0 and can be controlled via WLAN, or can communicate internally via WLAN. One robot also has a Prime Sense Carmine depth imaging camera available.
As further hardware 2 Google Project Tango Development Kits are available since September 2015 for the 3D acquisition of rooms.
