Abstract

Digitalization of historical objects constitutes an important element in the preservation of cultural heritage. Laser scanning technology enables rapid and detailed acquisition of information about the shape of measured objects. The resulting point clouds are widely used for inventory and numerical modeling of historical structures. After processing, these data become part of Historical Building Information Modeling (HBIM) models. The scope of attributes and features contained in these databases is diverse, as this technology has not yet been standardized in a manner analogous to BIM models. The present study describes the current state of knowledge about the Point Cloud Spatial Expansion (PCSE) method, which enables the determination of symmetry and deformation parameters of historical structures that are significant from the HBIM perspective. Furthermore, the study presents current directions of development of the PCSE method as well as potential areas for its further application.
