velopments in, and applications of,
close-range photogrammetry. It also gives an
outline of possible and desirable de-
velopments in the future. The author is aware

report attain such a goal.

ABSTRACT: The activities of ISP Commission V include all phases of
non-topographical photogrammetry: cameras, photography, graph-
ical and numerical mensuration, data reduction, and presentation of
results. Single metric cameras, stereometric cameras, and measuring
equipment with a series of accessories constitute instrument systems
which are very convenient for certain applications, e.g., architectural
photogrammetry. The analytical approach for data reduction opens
the doors for multicamera photography, rigorous least-squares ad-
justment, different models for the calibrations of interior orientation
parameters, use of non-metric cameras, etc. Integration of measure-
ment with succeeding data handling also is accomplished by digital
analysis of data. Close-range photogrammetry is widely used in ar-
chitecture and biomedical applications. A further increase in the use
of photogrammeiry as a measuring tool in production processes in
industry and civil engineering is to be expected.
The content is partly based on replies to an
enquiry sent to the invited authors, and the
panel members for the Commission V ses-
sions of the ISP Congress in Helsinki 1976,
and partly on the personal opinions of the
author. It is perhaps unfortunate that all who
have very kindly contributed have never had
have them discussed by their world col-
leagues. If this report is not an exhaustive
survey of today's (July 1975) close-range
photogrammetry, at least it will serve as a
basis for discussion on the state-of-the-art and
its future development.
