Spanish researchers use UAV data in 3D modelling

Granada, Spain: Researchers at the University of Granada, Spain, developed a 3D imaging system that scans 3D models of historical buildings using data obtained from an unmanned aerial vehicle (UAV). This is the first 3D imaging system to combine the use of UAVs, image-based 3D modelling technologies, and virtual representation of models to produce a realistic modeling of 3D objects from images.

To date, UAVs have been used in many research fields, as they are fast and they can overfly abrupt areas, avoid large obstacles and provide information from multiple sensors. Now, UAVs can provide a realistic modelling of 3D objects from images obtained from sensors, stereoscopic cameras and multiple geolocated images obtained from different angles.

Different University of Granada research groups participated in this project: the Grupo de Modelos de Decision y Optimizacion (MODO), the Grupo de investigacion en Informatica Grafica (GIIG); the University of Granada Virtual Reality Laboratory and the companies Intelligenia Dynamics and Virtum Graphics, which are University of Granada spin-offs and are aggregated to the Biotic Campus of International Excellence (CE). In addition, the CIE will support this research project.

The project is also supported by the Patronato de la Alhambra y el Generalife an CETURSA Sierra Nevada S. A, which belongs to the Junta de Andalucia.
