ABSTRACT 
The normal case of close-range photograph is realized by using WILD P32 terrestrial 
camera in which the base is changeable and known. With a system that has been 
developed for this purpose, photographs have been obtained by using a single metric 
camera which is capable of sliding on two steel bars ranging from 1 mm to 400 mm. 
While the base can vary from 1 mm to 400 mm if the photographs are taken 12 cm base, 
it will provide technical characteristics of WILD C12 and C120, and it allows user 
to obtain drawing outputs of 1/50, 1/100 and smaller scales by using WILD A40 
Autograph. Also if photographs are to be taken at 400 mm base, larger-scale drawing 
outputs can be achieved. This system has been successfuly in use in the close-range 
photogrammetric applications, such as archaelogical and architectural projects.

l. INTRODUCTION 
Many methods of close-range photogrammetry 
require special equipment, both for taking 
of the photographs and their subsequent 
measurement, and the availability of these 
Special cameras and plotting instruments 
has allowed the full potential of close- 
range photogrammetry to be realised in 
many branches of science and engineering. 
Non-topographic applications of photog- 
rammetry are made in the areas of medicine. 
dentistry, architecture, human locomotion, 
archaelogy, experimental analysis of 
structures, hydraulics, ship building, 
animal husbandry, deformations of dams, 
glacier and earth slide movements, vehicle 
motion, missile tracking, accident recon- 
Struction, and underwater events, to name 
but a few. In most of the applications 
listed above, a ground-based camera is 
used. Close range metric cameras include 
single cameras and stereometric cameras. 
There are three main problems to be resolved 
in ground-based cameras. These are 
respectively camera position, camera- 
object distance, and the orientation of 
the camera image plane. Single cameras, 
in original using, mounts directly on the 
telescope of a theodolite to overcome these 
problems. On the other hand, because the 
camera position can be determined precisely 
and the orientation of the axis of the 
camera set to any desired direction, much 
more can be known of the relative and 
absolute orientation of a pair of photograrhs 
in close-range photogrammetry than in 
aerial work, and this offers advantages. 
Some situations call for stereometric 
cameras, where the axes of the two cameras 
are parallel, and a special instrument has 
been developed and designed to exploit 
fully this known geometry by using one 
single metric camera.
