but one that can be used to indicate that developments in
close-range photogrammetry and machine vision will con-
tinue to be both profound and rapid. In spite of the impact
of new technologies, there are many research goals related
to existing theories and technologies that need to be
realised and work on these areas can be expected to con-
tinue. Such current topics include real-time image
sequence analysis, automated sensor orientation and cali-
bration, feature extraction and image matching.
In recognition of the emerging new technologies in inter-
disciplinary areas associated with close-range imaging,
along with an understanding of current research topics
and the prevailing state-of-the-art in digital photogramme-
try, Commission V has proposed the following resolutions:
- Resolution V.1 Automation for Vision Metrology, recom-
mends that stand-alone measurement systems inte-
grating one or more imaging sensors and CAD/CAM,
along with innovations in projected light systems for
off-line and on-line vision metrology, should be further
studied; and that target and feature extraction with
associated solutions to the multi-image correspon-
dence problem should be developed.
- Resolution V.2 Scene Modelling for Visualisation and
Virtual Reality, recommends that automatic image
analysis techniques to extract models of objects and
scenes for applications in visualisation and virtual real-
ity should be further developed; and that mechanisms
be implemented for co-operation between Commission
V and computer graphics and computer vision groups.
- Resolution V.3 Human Motion and Medical Image
Analysis, recommends that research and development
in techniques and systems for medical imaging, human
motion studies, expression analysis and sports formu-
lation analysis should be continued; and that Commis-
sion V should intensify co-operation and collaboration
with the communities of medical/biomedical engineer-
ing, sports science and human/apparel engineering.
- Resolution V.4 Application of Close-range Vision Tech-
niques and Spatial Information System to World Cul-
tural Heritage, recommends the further development of
integration of close-range vision techniques and spa-
tial information systems for 3D reconstruction and doc-
umentation of monuments and buildings for world cul-
tural heritage; and proposes further adoption of
advanced techniques for the mapping, documentation
and recording of the World's cultural heritage.
- Resolution V.5 Image Sequence Analysis, recommends
investigations of core research topics be promoted, in
close co-operation with researchers in, for example,
engineering and computer vision; and proposes con-
tinued investigations of algorithmic aspects and devel-
opments in computational systems for applications
with special emphasis on time-constrained solutions.
- Resolution V.6 Vision and Animation, recommends the
development of image-based techniques for use in
character and environment generation tasks; and the
study of methods and technologies to support the
interaction of real and virtual objects; and that collabo-
ration with the computer vision and animation commu-
nities be intensified.
- Resolution V.7 Integration of Ground-based Vision
Techniques with Aerial/Space Images, recommends
190
that new models and techniques for close-range and
aerial/space image integration should be developed,
with a focus on aspects such as the combination of
data from various sources, object extraction tech-
niques, 3D modelling and texture mapping.
WG V/1 ‘Close-range Imaging and Metrology'
by Chairperson: Clive Fraser, University of

and Co-Chair:
State of the Science and Technology
Development themes in close-range imaging and vision
metrology over the past four years have focused to a large
degree upon automation in all phases of the photogram-
metric process. Specific examples have included further
development of "intelligent" cameras, stand-alone meas-
urement probes integrating one or more imaging sensors,
and projected light systems for off-line and on-line vision
metrology. There have also been further advances in target
and feature recognition, with associated fast and robust
solutions to the multi-image correspondence problem and
new developments in models and procedures for auto-
mated sensor orientation and calibration. A resurgence has
also been witnessed in the development of integrated sys-
tems, where the vision metrology component is used as a
real-time dimensional control mechanism for machining,
milling or cutting control, for example. Progress in this area
has given rise to further work on the integration of vision
metrology and CAD, and on model-driven object recon-
struction. Generally, the state of the science and technol-
ogy of vision metrology could be characterised as reason-
ably mature in terms of fundamentals, with considerable
development attention being given to advances in system
automation, performance, reliability and productivity.
Main Accomplishments for the Period 1996-2000
Participation in the Optical 3-D Measurement Techniques
IV conference in Zurich, Switzerland from September 29th
to October 2nd, 1997. The WG organised Technical Ses-
sion 5.
Two newsletters were distributed and an informal WG
business meeting was held in Zurich in October, 1997. A
web-site was developed to aid in dissemination of relevant
information regarding WG activities and society events
(http://www.geom.unimelb. edu. au/isprswgv1/).
The focus of working group activity in 1998 concerned
participation in the very successful ‘International Sympo-
sium on Real-Time Imaging and Dynamic Analysis’ which
was held in Hakodate, Japan from June 2nd-5th. Of all the
working groups in Commission V, WG V/1 drew up the
most papers, namely 37. A second activity of note in 1998
was the Coordinate Measurement Systems Committee
(CMSC) conference held in St Louis in early July. Of the
papers presented at the CMSC, eight dealt with vision
metrology systems and were thus very relevant to WG V/1.
Further information on the CMSC is available at the fol-
lowing web-site: www.cmsc.org.
The principal activity for WG V/1 in 1999 was the Interna-
tional Workshop on Mobile Mapping Technology held in
Bangkok from 21-23 April. The WG was a co-organiser of
this successful conference, which had close to 200 partic-
ipants from 17 countries. Of the 42 oral presentations, a
