UTILISATION OF LASER SCANNING FOR INVENTORY OF AN ARCHITECTURAL OBJECT USING THE EXAMPLE OF RUINS OF THE KRAKOW BISHOPS' CASTLE IN IŁŻA, POLAND.

The terrestrial laser scanning with the close-range photogrammetry is now one of the most effective and most accurate, non-invasive methods of historic monuments inventory, especially during in-field archaeological and architectural works. In addition to the possibility of object's geometry registration, together with imaging documentation, the laser beam intensity of reflectance has recently become more important. It has been widely applied (as a complementary parameter) directly in the analytical works and monumental objects' surface detection, as well as, indirectly, during the diagnosis of the historical substance. The objective of this paper is to discuss selected issues related to performed field works concerning the ruins of the castle in Iłża, in Poland, which include acquisition and integration of data, as well as analysis and interpretation of the mentioned intensity of the reflectance parameter. The final result is the practical utilization of data for evaluation of behaviour of selected parts of a described object. Works are performed with the use of non-destructive methods of documenting and recognition of cultural resources, developed by the Stefan Wyszynski University in Warsaw within the research project "Utilisation of laser scanning and remote sensing for protection, investigations and inventory of the cultural heritage. Development of non-destructive, digital methods of documenting and recognition of resources of the architectural and archaeological heritage", within the programme of the Minister for Science and Higher Education, called "The National Programme for Development of Humanities".
