Another major event related to Resolutions
1.1 and 1.2 is the ASP Symposium on Close-
Range Photogrammetric Systems which was
held on the Urbana-Champaign Campus of
the University of Illinois in July 1975. This
meeting was sponsored by the American So-
ciety of Photogrammetry in cooperation with
ISP Commission V and the University of Il-
linois. Pertinent information about this sym-
posium is given later in this report.
Analytical methods are now used exten-
sively in non-topographic photogrammetry.
Substantial progress in this area has taken
place during the past four years and great
strides are expected in the immediate and
near future.
ACTIVITIES IN RESPONSE TO RESOLUTION 1.3
Working Group V/3 was established in
November 1972 to study the theme “Metrical
Aspects of Non-Conventional Imageries, with
Emphasis on Holography and Thermal Im-
ageries.” This Working Group was headed by
Professor Dr. E.M. Mikhail, Purdue Universi-
ty, until September 11, 1974; thereafter, Dr.
MK. Kurtz, Jr., U.S. Army Engineer Topog-
raphic Laboratories, Fort Belvoir, Virginia,
headed the group.
In Helsinki, Working Group V/3 will be in
charge of one session (Holographic and Moiré
Systems and Applications in Close-Range
Photogrammetry). The following invited
papers are planned for this session: “Three-
Dimensional Location and Measurement by
Coherent Optical Methods,” J.W.C. Gates
(UK); “Simultaneous All-Around Measure-
ment of a Living Body by Moiré Topog-
raphy,” H. Takasaki (Japan); “Comparison of
Optical Contouring Methods,” N. Balasub-
ramanian (USA); and “Canadian Contribu-
tion to Hologrammetry,” J.P. Agnard
(Canada).
Members of this energetic working group
actively participated in the Symposium on
Coherent Optics in Mapping organized by the
Society of Photo-Optical Instrumentation
Engineers (SPIE) in March 1974, the March
1975 Convention of the American Society of
Photogrammetry, and the July 1975 ASP
Symposium on Close-Range Photogrammet-
ric Systems. Dr. Kurtz compiled an extensive
bibliography on “Potential Application of
Holography in Photogrammetry and Map-
ping.” While no direct application of the
hologrammetric measurement techniques
PHOTOGRAMMETRIC ENGINEERING & REMOTE SENSING, 1976
has been reported in the open literature so far,
it is universally believed that coherent optics
have the potential to play a number of key
roles in a wide variety of non-topographic
photogrammetric systems of the future.
ACTIVITIES RELATED TO RESOLUTION 2.1
Working Group V/2, chaired by Professor
Dr. W. Faig, University of New Brunswick,
was formed in November 1972 to study the
“Photogrammetric Potentials of Non-Metric
Cameras.” The following major points of in-
terest were identified within the overall
theme of this Working Group:
e Definition and classification of non-metric
cameras.
e Calibration of non-metric cameras:
Methods and parameters; comparison of ap-
proaches,
Accuracy and tolerances,
Repeatability and recalibration,
e Ojbect-space control requirements and actual
determination of control,
* Comparison of metric and non-metric photo-
grammetry interms offeasibility, economy, and
simplicity,
* Evaluation of non-metric photography and in-
strumentation used,
€ Practical and experimental experiences, espe-
cially in the area of quality control in industry.
Atthe Helsinki Congress, two sessions will
be devoted to the activities of this most active
Working Group. Inthe session entitled ^Prob-
lems Associated with the Use of Non-Metric
Cameras in Photogrammetry,” Dr. Faig plans
to reporton an extensive survey he conducted
on the use of non-metric cameras throughout
the world. This session will also feature the
invited paper “Accuracy Aspects Concerning
the Interior Orientation of Non-Metric Cam-
eras,” O. Kolbl (Switzerland).
In the session devoted to “Practical Experi-
ence with Non-Metric Photography”, one in-
vited paper is planned: “The Use of Non-
Metric Cameras in Monitoring High-Speed
Processes, M.C. van Wijk and H. Ziemann
(Canada).
This session also will feature a panel discus-
sion on “The Actual Use of Non-Metric Cam-
eras in Photogrammetric Practice.” Invited
panelists will include the following col-
leagues: J. Badekas (Greece), I.A. Harley (Au-
stralia), J. Hohle (USA), O. Jacobi (Denmark),
G. Ladouceur (Canada), H. Schéler (GDR), Z.
Sitek (Poland); W. Faig (Canada), moderator.
The photogrammetric potential of non-
metric cameras was one of the main topics of
discussion at the July 1975 ASP Symposium
on Close-Range Photogrammetric Systems.
From all indications, it seems that non-metric
cameras are starting to gain general accept-
