ABSTRACT
The graphic representation of historical monuments is traditionally performed with the assistance of tape measure. Whit
this purpose, all the necessary elements for its representation are measured, "in loco". This traditional technique, used in
most of the works carried out in Brazil, is based on direct measurements on the monument. This measurements are time
consuming dependent on the conservation state of the monument. They can even damage the monument. After the
Second World War, the conservation of monuments was motivated, leading, in 1964, to elaboration of the International
Charter about conservation and restoration of monuments, known as Charter of Venice. Since then, several countries,
including Brazil, began to establish programs for maintenance of their historical monuments. The International Council
of Monuments and Sites - ICOMOS recommended that each country should constitute a photogrammetric record of its
monuments and sites, since photogrammetry is considered the main and more advanced method for surveying. This
paper shows the photogrammetric survey made in the “Solar of Rosário", a monument placed in the historical center of
Curitiba — Paraná — Brazil. The survey was done with a Rolleiflex 6006 camera and the recording was performed by the
method of mono-differential restitution, which presupposes the solution of the problem (representation of an object)
with observations in a single frame photography. The work was divided in three stages: First, the recognition of the
monument and photogrammetric survey; second, the topographic survey of the control points; and third, the mono-
differential restitution. The mono-differential restitution was made through the *Monorestituidor Digital" program, that
is associated with a PC based CAD-MicroStation system and its module for image processing IRAS-C. The mono-
differential restitution was performed according to the following steps: a) interior orientation; b) approximate space
orientation: c) external orientation; d) vectorial digitising of the elements of interest and, finally, e) the transformation
between the referential of the image space and referential object space and the adopted projection system.
1 INTRODUCTION
The majority of Countries have shown its preoccupation
respect to the its culture preservation, what presupposes,
among other factors, the conservation, restoration. and
consequent heritage classification of the architectural
monuments and archaeological sites. The conciliation
between the preservation of the historical heritage with the
regional development has continually been, object of study,
redirecting and revitalizing the activities of use of the
constructions that represent historical monuments of the city
or of the culture immigration.
Several works related to the monuments conservation and
restoration, be them architectural, archaeological or
historical character, have shown the importance and the
applicable of the photogrammetry for this aim.
Programs of maintenance of historical monuments were
developed over all the world. In Brazil the subject began to
be discussed in 1920, nevertheless there are few works that
used the photogrammetry for data acquisition. With the
