In the analysis for camera 6 hours of working time per da:/ and
15 hours /two-shift system/ for another instruments was assumed*
Executing different kinds of work in the scope of architectural
inventory one camera can supply data for: one rectifier /not
fully exploited/, one orthophot, one or two plotters* However
one camera can supply data for the above mentioned equipment
in office work, but technical aspects of complicated objects
measurements /very short and very long distances of taking
photographs 1*0 - 100 meters/ requires the application even on
the some objects, several cameras with different principal
distances, or one camera with different lens cones* It is
necessary to understand, that in this case the above mentioned
cameras will not be fully exploited*
Taking into account very strong object differentiation and width
range of variability of the coefficients describing producti
vity of individual methods /o.4 -v6*0/ we can see from econo
mic analysis, that individual characters of the monuments or
architectural object, determines time and cost of preparation
of architectural documentation*
5. CONCLUSIONS ,
i- Comparing the requirements which instruments used for
architectural photogrammetry should fulfil, with technical
parameters of widely available instruments one can state
that terrestrial cameras, stereometric cameras and plotters
makes possible to plot almost all cases which occur in
architectural photogrammetry*
ii- Some difficulties arise when the equipment from different
producers is used* Such set of instruments are very often
not compatible.
iii- Instrumentation for preparing of the documentation in pho
tographic mode are not adequate for all cases which can
be met in practice. Conventional rectifiers and ortoph^to-
scopes were designed for topographical purpose and don t
allow to rectified considerably tilted photographs / 30°,
45°, 60°/ and to develop the surface / such form of docu
mentation is sometimes very convinient /•
iv- Comparing three basic methods used in architectural docu
mentation we found that the stereoscopic method is 2.5
time's more expensive then the rectifieying method, and
1.4 times more expensive then the ortophoto method*
v- It is not possible to give objective comparison of these
three methods because they produce different result and
are usufull for a different type of object.
vi- The cost and time required for execution of the architec
tural documentation more strongly depend on object diffe
rentiation then on applyed method.
