Subject: kbvision + nexpert-object
hi,
we are about to spend some money....
... for a system that enables knowledge processing
for vision purposes.
i wonder, if someone has experience in the following
two programs:
o nexpert object: an general purpose expert system
o kbvision : a computer vision tool, with a
special 'knowledge modul'.
i'd be interested in the experience of people using
these programs; especially how easy/hard it is
to formulate the knowledge, and how it is integrated
into the evaluation process.
hoping for answers

Organization: Universita' di Padova, Italia
Subject: Hardware for early vision
We are doing a research about a passive dynamic vision guided vehicle.
Completed the first theoric part, we have to make the effective
realization of this vehicle.
We need the necessary hardware for image acquisition from a videocamera
and for their subsequent elaboration (tipically: edge detection).
We ask for informations about available products in the market for
this purpose (in real time, 20-25 frames/second).
Hence we need frame-grabber cards and/or DSP cards for SUN or PC platform.
We are also very interested in receiving comments and suggestions from users
of these cards, especially about programming tools.
Furthermore we are looking for the same kind of informations about
digital controlled Pan&Tilt devices.
Thanks in advance
Best regards
Enrico Fedrigo

From: wong@inf.ethz.ch
Ph.D. STUDENT IN MAP RECOGNITION
(Zurich, Switzerland)
We have a position to be filled immediately for a student who is
interested in doing a Ph.D. in Computer Vision. (We would call here a
Ph.D. student an "assistant", meaning a research and teaching assistant.)
Our project is the recognition/interpretation of land registry maps/plans.
We are a technical university and in this project we are cooperating
with industry (i.e. we have a "real life" problem to solve but we also
want to do scientific research).
The position is a full-time paid position and the duties are roughly
40% Teaching and supervision of undergraduates/marking of assignments, ...
50% Research: working in the map recognition project
10% Education: this amounts to attending about one course per semester
Applicants for this positions must have a Master's degree (or a Diploma
if coming from a European country) in Computer Science or Electrical
Engineering. Applicants should also have a high grade point average.
It is highly desirable to have experience/knowledge in the areas

''' Circular Letter # 1 ''''
'' April 1993 ''
Invitation
With this first circular letter we intend to characterize the new WG II/1
of the ISPRS. You are kindly invited to participate in the activities of this
Working Group.
The work of Commission II for 1992-1996 will focus on ''Systems for Data
Processing, Analysis and Representation''. The President of this Commission is
Dr. Mosaad Allam, Canada, who invited us to chair the WG II/1 ''Real Time
Mapping Technologies''.
The first WG-meeting probably together with other WGs is planned during
the Photogrammetric Week (20.-25.9.93) in Stuttgart. The topics concerning the
terms of reference, the WG-objectives, and more are listet below and can be
discussed and supplemented at that meeting. We look forward to seeing you in
Stuttgart.
Yours sincerely,
Kurt Novak & Michael Hahn
TERMS OF REFERENCE
The Working Group will deal with the following topics:
* Design and development of real-time mapping systems.
* Survey recent and future developmens in real-time mapping systems.
* Design of integrated digital systems for real-time utility mapping
and GPS-Van technologies.
* Investigate sensor information processing and analysis issues in
autonomous vehicle navigation systems.
* Assess the role of stereo-vision and kinematic GPS technologies in
integrated real-time mapping systems.
* Establishment of contacts with Working Groups of Commission I, II, III, V
interested in integrated sensor orientation, GPS-INS integration, object
recognition or other relevant issues.
OBJECTIVE OF THIS WORKING GROUP
WG II/1 will focus on the development and design of real-time mapping
systems. A first goal is the identification of researchers at universities,
government agencies, and private companies that are interested in the
development and application of this technology. As this topic is very
interdisciplinary, we will promote intensive cooperation between different
working groups and commissions of ISPRS, as well as other societies interested
in digital mapping, integrated sensor systems, facility management, computer
vision, and GIS. As a result of our efforts, the integration of sensors for
accurate and fast digital mapping shall become an accepted and superior
technique for digital data collection.
DEFINITION OF REAL-TIME MAPPING
Mapping is the process of recovering geometric and physical properties
of the world from images or similar information sources. The primary data are
mainly intensity images, distances, colour and other spectral information, but
can be also other types like thermal scannings for example. Mapping then is
the procedure of extracting a suitable representation from the primary data
and transforming this representation to the desired output, like location,
structure or shape of visible surfaces or objects. A goal of mapping is to
combine multiple observations into a consistent map of the environment. To
reduce complexity and gain applicability other sensors (GPS, INS) for
positioning and orientation of platforms should be integrated in a mapping
equipment.
Real-Time Mapping is concerned with the combination of positioning,
imaging, and other data collection sensors for digital mapping and their
integration in a database. The combination of absolute and relative
positioning devices enables the user to locate features in a global reference
frame without object space control. Real-time mapping systems can be used on
mobile platforms both for topographic mapping and facility management, as well
as vehicle navigation.
REAL-TIME MAPPING RESEARCH ACTIVITIES AT OHIO STATE UNIV. AND STUTTGART UNIV.
The list of research activities compiled below concentrates on efforts
at Ohio State University and Stuttgart University. With this listing we want to
point out our interest in possible cooperations with other Working Groups.
** Integration of GPS and Ditital Cameras for Platform Orientation:
GPS and digital images are used for automatic positioning and orientation of
the sensor platform. Sequences of digital or video images are collected and
stored in a GIS. ## Keywords: sensor integration, platform orientation.
** Aerial Laser-Scanning:
GPS, INS, digital images, and laser distance data are combined for the
reconstruction of surfaces (mostly DEMs in forest areas and costal areas).
## Keywords: data fusion, polar photogrammetry, surface reconstruction.
** Autonomous Vehicle Navigation:
Image sequences are analyzed by tracking points and linear features to
estimate the vehicle's trajectory and motion, and to reconstruct objects in
mono- or stereo sequences. On-line triangulation techniques, such as Givens
transformations, and 3D Kalman filters are applied.
## Keywords: correspondence/optical flow, structure from motion, on-line
triangulation.
** Integration of GIS and Image Analysis:
A priori knowledge of spatial data-bases is used to aid automatic image
analysis. Information extracted from images is immediately available to
update GIS. ## Keywords: GIS aided orientation, object reconstruction,
map revision.
** GPS-Van Technology:
A digital stereo-vision system is integrated with GPS and INS in a vehicle for
the automatic generation of highway inventories. Collected data are
immediately interfaced to a GIS and can be combined with digital aerial
imagery for mapping. ## Keywords: sensor integration, stereo-vision,
transportation planning.
** Real-Time Mapping Satellite:
The design of a mapping satellite is studied; it will allow for real-time data
collection from space using stereo-imagery and GPS.
## Keywords: map revision, satellite mapping.
** Utility Mapping System:
Cameras are installed at the wing-tips of an airplane to take stereo-image
pairs of powerlines. The position and orientation of the airplane is
determined by 3 GPS antennas. ## Keywords: stereo-vision, platform orientation,
GPS direction finding.
** Surface Reconstruction for Earth Moving Equipment:
A digital stereo-vision system automatically reconstructs the terrain in front
of a working bulldozer. A DEM is computed and compared to an artificially
designed surface in a CAD system. The bulldozer's blade is positioned by
kinematic GPS to accurately move earthwork according to the specifications.
## Keywords: stereo-vision, kinematic GPS, structured light.
PLANNED ACTIVITIES OF WG II/1
At this stage it not possible to precisely outline the activities for the next
years. However a rough plan is:
Organization of workshops, sessions and presentations
* Conduct a survey on the state-of-the-art in real-time mapping and the
activities of different institutions.
* Sessions at the ISPRS Commission II Symposium in Ottawa, Canada (June 1994).
* Tutorials on ``Sensor Integration'', ``GPS-Photogrammetry'',
``Real-Time Mapping'' at the ISPRS Commission II Symposium in Ottawa, Canada
* Session at the Workshop on High Precision Navigation (Germany 1994/5)
* Actively participate at the following conferences:
Photogrammetric Week, Stuttgart (September 1993),
Commission V Symposium, Australia (April 1994),
Commission III Symposium, Germany (September 1994).
* Joint Workshop on `Computer Vision in Photogrammetry'
in Stuttgart, Germany (8-10 November 1995);
organized together with WGs I/5 and III/2+3
* Joint Workshop with Intercommission WG II/III in USA (1995)
with Intercommission WG III/1 in Barcelona (1995)
