Architectural heritage research and preservation requires development of diverse tools and a system organizing in a structured way the creation, storage and distribution of comprehensive information about historical buildings. Development of digital technologies and 3D scanning of buildings of cultural heritage combined with 3D virtual reconstruction allows creation of important tool for understanding and reconstructing the past. Photogrammetric methods for creating and processing of spatial (3D) images of historical and architectural monuments are finding a growing application. Such approach is becoming a cheaper alternative of expensive laser scanning. The article analyses the opportunities for the use of different ICT tools including inexpensive digital imaging options for preservation and exhibiting of large and diverse Bulgarian cultural heritage.
