PHOTOGRAMMETRY, LASER SCANNING AND HBIM FOR CONSTRUCTION DIAGNOSTIC

Abstract. The aim of this article is to show today's possibilities of the documentation of damaged monuments by various technologies on a case study. Laser scanning, mobile laser scanning, terrestrial photogrammetry using hand-held camera, and drone aerial photogrammetry were used. The outputs were textured and non-textured point clouds and an aerial orthophoto of the object. The clouds were compared in terms of possible deformations, the issues of overall accuracy and time required to focus the object were also discussed. The outputs were used for the basic plans of the building, intended for the planned reconstruction and also for the creation of a model for HBIM.
