ABSTRACT 
Examples of photogrammetric digital image processing for architecture and historical building preservation and their presentation are 
discussed in the paper. At the Czech Technical University in Prague, the photogrammetric and physical measurement is performed in 
the framework of the co-operation between the Laboratory of Photogrammetry (Faculty of Civil Engineering) and the Laboratory of 
Quantitative Methods of Monuments Research (Faculty of Nuclear Physics and Physical Engineering). Based on a grant of the 
Czech Grant Agency, a large project on historical monument documentation by using a new digital technology has been started 
started. The project is defined as a complex research for historical monument documentation using digital photogrammetry, physical 
methods and GIS. The measured data set processed into a digital model serves as a basis for architectural and historical analysis 
(Faculty of Architecture). For testing of a new technology, the historical centre of the town Tele, (which is included into the list of 
the world monuments of UNESCO) is selected. The measurement of historical part of the town Tele represents the spatial (3D and 
2.5D) analysis of about 50 objects (facades) and several interiors of historical buildings. The photogrammetric measurement involves 
the use of various methods (geodetic micro-network, analytical aerotriangulation, UMK cameras, réseau camera, non-metric digital 
cameras and video sequences). The development of classified knowledge about Tele gained through historical and architectural 
analysis in the form of an information system will be connected to the state coordinate system. The results will be transferred also 
into the recently established database of the Czech historical monuments. For description of compiled data, we are going to use 
Extended Mark-up Language (XML) which we suppose to be the best tool available for description of structured data independently 
on the software being currently used. Web presentation and searchable database of the project data will be derived from the XML 
documents. 
1. PHOTOGRAMMETRY 
Terrestrial photogrammetry is often used in a wide variety of fields - one of them is preservation and reconstruction of historic 
buildings. It is necessary to measure the status quo for documentation, for architectural analysis and any proposed reconstruction in 
these fields. Last 15 years, the digital technology has made a great step in the photogrammetry. 
The Laboratory of Photogrammetry at the Czech Technical University in Prague is the largest university photogrammetric centre in 
the Czech Republic. It is placed at the Faculty of Civil Engineering and it works in co-operation with the Laboratory of Quantitative 
Methods of Monuments Research. The Laboratory of Photogrammetry is traditionally joined to the Department of Mapping and 
Cartography the same as the Laboratory of Remote Sensing. A set of photogrammetric equipment is located for about 80 students 
and 5 Ph.D. students on the area of 200 m 2 . The equipment of the Laboratory of Photogrammetry involves photogrammetric cameras 
UMK 6.5,10,20,30, SMK 5,5 for terrestrial photogrammetry and digital cameras Olympus 2000C and Olympus 2500. The CCD 
Video Camera Sony is used for digital image sequence. The laboratory is equipped for digital stereo photogrammetry (small digital 
stations with stereoscope equipment - DVP Leica and VSD Krakow, professional stations with Crystal Eyes hardware stereo 
equipment Intergraph ImageStation - Unix and ImageStation SSK and the Czech-made photogrammetric workstation PhoTopol). For 
some projects, precise PC-connected stereocomparators and a number of PC-connected analogue plotters are still used. 
The Laboratory of Quantitative Methods in Monuments Research of the Faculty of Nuclear Physics and Physical Engineering was 
established in the year 1996 based on a grant by the Czech Ministry of education (MSMT). The Laboratory is active in physical 
methods and a photogrammetric part for documentation and analysis. It was decided at its foundation that both the operating budget 
and the financing of research projects would be applied for through grant agencies and from research program of TU. The laboratory 
is equipped for physical methods - namely thermoluminescence dating, X-ray fluorescence analysis and photogrammetry 
(RolleiMetric 6006, 40 and 80mm, CDW and MSR software for digital single and multiphoto processing). The work of the 
Photogrammetric laboratory is mainly oriented to the 3D measurement and documentation of historic buildings and monuments by 
terrestrial photogrammetry. This work is very interesting for architectural historians and experts from the State Institute of Care of 
Historic Monuments.
