3.2 Education
3.2.1 Photogrammetry and remote sensing courses
In the photogrammetry and remote sensing discipline following
undergraduate courses are currently given and similar courses
have been given during the period 2000-2004:
3.2.2 Photogrammetry and image processing, levelA-basic.
(in Swedish)
The course is an introduction to photogrammetry whit focus on
photogrammetric mapping from aerial images. Throughout the
course a project work is realised, including orientation of a
stereo pair and stereo plotting in both an analytical instrument
and a digital photogrammetric workstation. Basics in image
processing processes, related to digital photogrammetry, are
also covered.
3.2.3 Photogrammetry analytical/digital, levelB-
intermediate. (in English if requested)
The course includes analytical fundamentals in photogrammetry
and standard processes in modern digital photogrammetry; c.g.
aerial triangulation, generation of elevation models and
production of ortho photos.
3.2.4 Remote sensing level C-advance. (in English, if
requested)
Different types of satellites, sensors, etc., are treated. However,
the main emphasis is put on image interpretation and analysis.
The course also consists of a project work where a satellite
image is classified with respect to land use.
3.2.5 Industrial and special measurements level C (advance).
(in English, if requested)
Terrestrial photogrammetry is treated in the course with the
purpose of detecting e.g. displacements caused by, for instance,
stress. Also detection of 3D medium- to high-speed movements
by photogrammetric methods are treated.
3.2.6 Thesis work
Throughout the period both Swedish and international exchange
students have been using the terrestrial laser scanning
equipment in their thesis work. Laser scanning for elevation
modelling have been compared with traditional surveying
techniques, measurement and modelling of different types of
environments have been tested, including image based texture
mapping, and accuracy performance tests have been
accomplished. Besides thesis work using terrestrial laser
scanning, other students finalised their thesis work at the
National Land Survey of Sweden comparing data acquisition
from film based digital imagery with data acquisition from
digital imagery directly captured with a Leica ADS40 camera.
3.2.7 Photogrammetry and remote sensing facilities
In 2001 investments were made in four digital photogrammetric
Delta DPS system from GeoSystem in Ukraine. Later 2001 the
university invested in the latest technology in terrestrial laser
scanning, a Cyrax 2500 system from Leica Geosystems. The
university also holds an analytical Zeiss P33 sterco-instrument,
still in use, and for the remote sensing course the University
uses the Erdas Imagine software from Leica Geosystems. For
image interpretation ten mirror stereoscopes are available as
well as a wide range of aerial photographs for different types of
analysis. In 2002 the analogue Wild A7 stereo-instrument was
263
dismantled and 2003 our Balplex equipment and our Wild A8
instrument was taken apart. The Wild A8, equipped with
encoders for digital read-out, was in use until 2001, the Wild
A7 and the Balplex, on the other hand, had not been in use for
many years.
The Centre for Built Environment at the university possess one
FLIR THV 1000 longvawe infrared camera (8-14um) to be
mounted on a cart, a mast on a car, helicopter or fixed-winged
aircraft. The centre also has one FLIR THV 570 (8-12um)
infrared camera which could be used as stationary unit,
handhold or car mounted. The infrared systems described are
mainly used within different R&D projects for building,
technical infrastructure and environmental applications.
3.3 Research
Research and development has lately focused on the newly
invested terrestrial laser scanning equipment. Staff from the
university have attended international events like; the 5th
International Conference on Optical 3-D Measurement
Techniques in Vienna, Austria 2001, the CIPA International
Workshop on Scanning for Cultural Heritage Recording and the
ISPRS Symposium Close-Range Imaging, Long-Range Vision
both in Corfu, Greece 2002, and the 4th International
Conference on 3-D Digital Imaging and Modeling in Banff,
Canada 2003. At the CIPA Workshop in Corfu, the PhD student
from the university, Mikael Johansson, presented his paper —
"Exploration into the Behaviour of Three Different High-
Resolution Ground-Based Laser Scanners in the Built
Environment".
During the period 2000 — 2004 the main R&D activities at
Centre for Built Environment have been devoted to
development of passive gas imaging methods for methane, LPG
and biogas detection, which represent the Swedish part of an
EU-project named "Visualisation of Gas for Utilities and the
Environment" (VOUGE ENK6-CT2000-00054). The Swedish
budget runs to a total about 6 milj SEK, and is financed EC and
by the Swedish Government through the research council
STEM. Swedish partners in the VOGUE-project are University
of Gävle, Swedish Gas Centre (SGC), Southgas (Sydgas AB)
Malmô Firebrigade, and The Solid Waste Company of
Southwest Scania (SYSAV). Other EU-project partners are
ADVANTICA (former British Gas), Italgas, Glasgow
University, Siemens AG Germany, AOS Technology Ltd
(AOS) UK, Electrabel Ebel) Belgium.
In another ongoing project infrared technology has been used to
detect temperature anomalies in a greenhouse heated by gas
driven IR-radiators. The title of the main project is "Gas based
infrared radiant heating in greenhouses. Aspects of energy use
and plant development". Project partners are the Energy
Institute LTH Lund, Swedish Agriculture University Alnarp,
University of Gävle, Swedish Gas Centre (SGC), Kjell Ingvars
Greenhouse Company AB, Sotuthgas Malmoe, etc. The project
is financed by among others the Swedish Government through
the research council STEM.
3.4 Events
In October 2002, a two-day seminar about terrestrial laser
scanning was realised at the university, with more than 100
attendees and all major developers of terrestrial laser scanning
present as exhibitors.
