NON-TOPOGRAPHIC PHOTOGRAMMETRY, 1972-1976
growth and progress during the past four
years.
The use of photogrammetry in measuring
pertinent dimensions of car body models in
order to obtain production data was reported
in the Italian and East German (GDR) litera-
ture. Machine construction, metal working,
and quality control are areas in which photo-
grammetry has been used in GDR, the USA,
and USSR.
Austria, Canada, Czechoslovakia, Finland,
France, Hungary, Poland, Romania, South
Africa, Sweden, the UK, USA, and USSR re-
ported using photogrammetry in one facet or
another of mining engineering, e.g., in proc-
ess measurement in open pit mining, tunnel
cross-sectioning and profiling, geological
measurements, rock deformations, rock
mechanics investigations, monitoring of
products in mines, etc.
In Austria, Canada, Poland, Romania,
South Africa, Sweden, the USA, and USSR,
photogrammetric studies of objects in motion
for a wide variety of purposes were reported.
This category includes tracking hand motions
in industrial operations, studying glacier
movements, assessing deformations of
aerodynamic models in wind tunnels, track-
ing of particle flow in bubble chambers, and
evaluation of displacements caused by ex-
plosions, etc.
In Belgium, Canada, Norway, South Africa,
Sweden, the UK, USA, and the USSR, photo-
grammetry is used in the shipbuilding indus-
try, including some or all of the following
aspects: measurement of ship sections, mea-
surement of ship propellers in various stages
of fabrication, wave measurements, and posi-
tion determination in model experiments,
etc.
The use of photogrammetry in connection
with structures and buildings, e.g., to check
on the construction and/or to measure defor-
mations of chimneys, buildings, experi-
mental structural models, and/or large struc-
tures such as antenna reflectors and power
dams, were reported from Austria, Belgium,
Canada, Czechoslovakia, Finland, France,
Hungary, Norway, Poland, Romania, South
Africa, Sweden, the UK, USA, and USSR.
Austria, Canada, Romania, Sweden, UK,
the USA, and USSR reported using photo-
grammetry in one aspect or another of traffic
engineering, e.g., in traffic accident investi-
gations, profiling and cross-sectioning of
roads and traffic tunnels, road surface rough-
ness studies, ship path determination, etc.
Other miscellaneous industrial applica-
45
tions reported include studies of stability of
dump sites (Belgium, Poland, South Africa,
USSR), soil erosion studies (Poland, South
Africa, the UK, USA, USSR), underwater
mapping (Poland, South Africa, Sweden,
USA, USSR), forest economic studies includ-
ing the classification of growing trees (Au-
stria, Sweden), the determination of sagging
of powerlines under weight of freezing rain
(Canada), evaluation of fishing equipment
(USSR), and estimation of food-fish resources
(USSR).
CoNcLuDING REMARKS
During the period 1972-1976, significant
progress was made in various aspects of non-
topographic photogrammetry including:
€ substantial increase in new fields of applica-
tions, particularly in biomedical and industrial
photogrammetry, and a significant increase in
the volume of activities in architectural photo-
grammetry;
e development of new data reduction tech-
niques (mainly analytical) and the refinement
of established approaches;
€ significant increase in the flexibility and versa-
tility of close-range and terrestrial metric cam-
eras; and
€ opening the door for the use of small-format
non-metric cameras in non-topographic
photogrammetry by the development of data
reduction techniques particularly suitable for
non-metric photography; and the gradual ac-
ceptance of such cameras as data acquisition
tools, along with metric cameras, thus
broadening the range of cameras available for
non-topographic applications.
All indications are that the progress ac-
hived during the past four years will continue
at an even faster rate, and that great strides
will be made in all facets of non-topographic
photogrammetry in the immediate and near
future.
