Extended digital models for planning and managing interventions concerning complex buildings and urban environments

Abstract

The recent advances in the capture and processing of 3d information allow for the elaboration and management of documentation at different levels of resolution to be undertaken, enabling the application in documentation and viewing tasks. The system developed by the DAVAP group of the University of Valladolid, combines methodologies based upon terrestrial photogrammetry, Computer Vision and 3D Laser. The combination of all these provides support for the elaboration of Virtual and Augmented Reality models, concerning environments generated according to the preceding methodologies. This paper sets out the virtual models are exposed developed for the interior of buildings (Teatro Zorrilla de Valladolid), augmented archaeological environments (Teatro Romano de Clunia) and complex urban settings (Muralla de León and the Área de Rehabilitación Integral -ARI- Tierras del renacimiento).

The volumetric reference of the models generated proceeds from the register of dense 3D cloud points captured by the Optech 3D laser device Ilris 3d. The dense cloud obtained after the hit of different takes and optimized provides a precise global environment as a reference model for the incorporation of information proceeding from views and evaluation of metric properties. The digital support obtained permits the generation and viewing of the basic geometrical components exportable to CAD.
