Scan to HBIM Technology Problems: A Case Study of Holy Cross Exaltation Cathedral in Solikamsk, Russia

Abstract

AbstractBuilding Information Modeling is gradually becoming the standard in architectural heritage. The article discusses a method for converting point clouds into a three-dimensional information model. The point clouds for the cathedral were obtained by photogrammetry and terrestrial laser scanning methods. The current trend is a combination of Digital Photogrammetry with Laser Scanning. The combination of ground and aerial photogrammetry allowed the building to be digitally displayed in the best possible way. The model of the Cathedral of the Holy Cross Exaltation is the case study described in this paper. Modeling was carried out on the basis of such a combined point cloud. The modeling took into account the real state of both the building as a whole and its individual elements. Problems with the use of BIM modeling for historical objects can be considered difficulties with including all the inaccuracies of the real object. On the basis of historical photos, the historical view of the architectural monument has been recreated. BIM models play an important role in the documentation process. All information collected about the building becomes a single database, collected in one file. This is important for the subsequent work. Such knowledge bases about architectural monuments are aimed both at solving applied problems in the field of reconstruction and construction, and at spreading knowledge about architectural heritage.KeywordsArchitectural surveyBIM modelInformation modelHistoric appearanceArchitecture heritagePhotogrammetry
