An HBIM Methodology for the Accurate and Georeferenced Reconstruction of Urban Contexts Surveyed by UAV: The Case of the Castle of Charles V

The potentialities of the use UAV survey as a base for generation context mesh are illustrated through experiments on case study, Crotone Fortress, proposing systematic general methodology and two procedural workflows importation triangulated model, maintaining its real geographical coordinates, in Autodesk Revit environment Dynamo Visual Programming script [VPL]. First, texturisation urban was experimented with, using real-sized photogrammetric orthoimage material; therefore, reproduction discretised detailed areas tested. They were imported via by reading coordinates vertices every single face that constitutes model associating to each them corresponding colorimetric data. Starting from georeferenced mesh, nine federated BIM models produced: models, architectural fortress.
