Papers were read by Y.P. Kienko and M. Kirschstein on analytical methods of determination of co-ordinates
in terrestrial photogrammetry.
The Chairman, K. Linkwitz, reviewed the Invited Papers by W.V. Bóttinger and H.D. Preuss on the use of
photogrammetry in the design and construction of the Olympic Stadium in Munich. (included in the Report
of W.G.V/3)
There followed a report by J. Hóhle on the use of photogrammetry in underwater surveys. In this report, cases
in which the camera was used above as well as under the surface of the water were described.
During the discussion, various methods of improving the accuracy of analytical photogrammetry in
close-range applications were underlined, such as:
(1) use of self-calibrating photogrammetric systems;
(2) intersection of more than 2 corresponding light rays:
(3) increase base-distance ratio.
In his closing remarks the Commission President expressed special appreciation to K. Linkwitz for his work
in the application of photogrammetry during the construction of the Munich Olympic Stadium.

This session. under the Chairmanship of T. Oshima, was devoted to the measurement of holograms and moire
patterns. An introductory paper was presented by U.V. Helava (on metric use of holograms). A. Brandenberger
reported briefly on the work in this field carried out at Laval University (presented paper by J.P. Agnard). and
E. Keune discussed the paper by P. van Berchefeldt on the research carried out at the University of
Hannover.
During the discussion O. Jacobi indicated the use of a simple mirror for measurements of small objects. without
the need for the holographic method.
G.L. Gifford pointed out some definite advantages of the holographic technique. such as the large depth of field
and the possibility of deriving geometrical information on complex surfaces from one single hologram. where
in photogrammetric application several stereomodels would be required.
T. Oshima gave a short review of the paper bv H. Takazaki on the use of moiré technique for deriving precise
geometrical information.
The Commission President closed the meeting with the remark that work on hologrammetry will once more
have special interest in the activities of Commission V during the next four years.

This session started with a presentation by V. Dmitrotzenkov on work carried out in the USSR in the field of
lunar mapping. Methods were discussed as to control extension into the part of the moon which is invisible
from the earth, and mapping of lunar features from photographs taken from the Lunakhod I.
The second part of the session consisted of the continuation of the panel discussion on calibration of
short-range photogrammetric systems. The Chairman was H.M. Karara.
Short presentations were made by J. Ducloux, W. Faig, O. Kólbl and O. Jacobi on calibration of stable cameras
and **on the job" calibration methods of non-metric cameras. Methods for improving the photogrammetric
accuracy, such as use of convergent camera area and larger format cameras, were indicated.
In discussion, two opposite opinions were expressed by those in favour of the exclusive use of precise metric
cameras. Some claimed that saving in the cost involved in the use of cheaper cameras is usually minimal, in
comparison with the cost of measurement, computation and frequent calibration (Jacobi, Tienstra). Others
favoured cheap cameras because they are often better adapted to taking successive photographs at shorter
intervals. or for remote control (Karara, McNair). It was concluded that improvement in versatility of metric
cameras is desirable. Present cameras are designed for certain applications such as architecture, accident
surveys and terrestrial topographical photogrammetry.
