Description

Technical innovations in the field of engineering measurement techniques are the main focus of the Laboratory for Engineer Measuring Techniques:

  • LIDAR technology: terrestrial, airborn and mobile laserscanning
  • Digital 3D TOF technology: 3D scanner-cameras for capturing objects in real-time
  • Inertial-measuring techniques: GPS/INS sensors for positioning and orientation of plattforms
  • Calibration of laserscanners, 3D camera systems and inertial systems
  • Methods and processing techniques for positioning, orientation, filtering, localising, scanning, fusion, analysis, modelling and object reconstruction

The Laboratory supports lectures in the Bachelor study programmes "Vermessung und Geoinformatik" (Surveying and Geoinformatics), "Informationslogistik" (Informationlogistics) and in the Master programmes "Vermessung" (Geodesy) and "Photogrammetry and Geoinformatics". Therefore there are some installations for sensor calibration and laserscanning which are used within projects and Bachelor- or Master theses.

Another focus is on teaching strategic decision-making in the field of engineer measuring techniques. For that are mostly differnet sensors integrated. Planning and execution of such projects requires system analysis, process competence, method and solution competence and assists teamwork and social competence.

Furthermore the Laboratory supports research projects.

Laserscanning

Since 2000 the University of Applied Sciences Stuttgart / HFT Stuttgart uses successful laserscanning techniques, since 2003 with an own laserscanner (Leica). At this time five laserscanners are available (Leica ScanStation 2, Leica HDS7000, Leica ScanStation P20, Faro Focus3D, Faro Focus 3D X330), but for some projects scanners from companies like iQvolution, Trimble and Zoller&Fröhlich are used as well. Additionaly two Mobile Mapping Hand-held Scanner (GeoSLAM ZEB1, Faro Focus Freestyle) expands our equipment with their special characteristics.
12 licenses of Cyclone and numerous licenses of AutoCAD and CloudWorx are available to process the laserscanner data. Additional an external digital DSLR Camera with panoramic head can be used to create high quality panoramic images for mapping into a point coud.

The whole equipment is used very intensively for education in this laserscanning techniques. For research and Bachelor- or Master-theses it is used intensively as well.

3D TOF technology (scanner-cameras)

In the Laboratory four scanner-cameras SR4000 from the company Mesa Imaging are available. This new 3D TOF-technology is used for experiments of capturing objects in real-time. The camera-systems are calibrated in the Laboratory as well.

Inertial-measuring techniques

In the Laboratory there are some experiments to combine inertial-sensors for example with GNSS-sensors, Laserscanner, Hyperspectral- and Thermal-Cameras for different applications. In one research project a GNSS/INS combination is used for steering and flight-path processing of a gyrocopter which captures infrared images.
Sensors like APPLANIX, OXTS and XSENS are available for that

Laserinterferometry

With the available Laserinterferometer of the company Hewlett Packard (HP5528A) distance measurements with highest accuracy (<0,001mm) and angle measurements with highest accuracy (ca. 0,03mgon) are possible. This is used for checking surveying instruments and for measurements in industry.

Although this interferometer is designed for indoor laboratory usage, the equipment is successfully used as a mobile measuring method, e. g. for monitoring measurements in a nuclear power plant.

Frequency measuring unit

In the Laboratory there is a frequency measuring unit installed which can verify the measuring frequency of distance measuring instruments (phase measuring principle). The actual measuring frequency is compared to the reference frequency and a scale factor of the instrument can be processed.
