Problems of acquisition and postprocessing of 3D scans of large architectural objects

Abstract

The article presents the 3D scanning methodology for large architectural objects, using stationary laser scanners in case of objects of cultural heritage. The developed methodology was tested in the field during 3D scanning of architectural monuments of the city of Samarkand in Uzbekistan. Particular attention is paid to technical and organisational problems of the 3D scanning process of architectural objects which appeared during the Second Scientific Expedition of the Lublin University of Technology to Central Asia. Next, methods for obtaining digital models adequate to the assumed archiving goals and dissemination of cultural heritage of Central Asia are presented. The described case study is, according to the authors, representative for 3D scanning of much-frequented architectural objects being monuments of great importance for cultural heritage.
