Funeral enclosure - Rotunda Date - Timespan: 16th century
Funeral enclosure within the Rotunda precinct, which contains the tombs of two people, Hortaci Süleyman Efendi and a certain Yusuf Bey. The sheikh of the nearby dervish community, Hortaci Süleyman Efendi, and the Ottoman Sinan Paşa converted in 1590-1 the building into a mosque named after the first. The enclosure is one of the additions made in the monument, when it was converted into a mosque that are still visible today.
The monument was selected to be 3D digitised within the framework of the European Commission funded 3D-ICONS project by the Athena RC Xanthi's Division. It's exterior was captured in 3D using the Structure-From-Motion (SFM)
and Dense Multi-View 3D Reconstruction (DMVR) methods. Aerial and terrestrial photoshooting sessions were performed during the winter of 2014 always during cloudy days. A total of four digitisation
sessions were performed where each resulted a number of image sequences presenting the monument from different points of views. The terrestrial photoshooting sessions were implemented using camera tripods
and custom monopods (3m-9m adaptive). All aerial photoshooting was performed using a custom hexacopter equipped with gimbal remote controlled two axis tilt-roll camera base, first-person view (FPV) and GPS.
A pair of Samsung NX1000 20MP compact DSLR cameras with fixed 16mm and 20-50mm lenses were used. Agisoft PhotoScan (ver. 1.1) has been used for the production of monument's 3D digital replica. Although, flight paths were designed they
have been performed manually due to bad GPS reception (high buildings around the monument). Furthermore, the calibration of the cameras was performed by the software itself. The processing of the image sequences was performed on two computer systems (CPU IntelCoreI74820K 3.7Ghz, 64GB RAM, Radeon R9 290X,
Microsoft Windows 7 64-bit).
Additionally, empirical measurements between strong (in terms of visibility) feature points on the surface of the monument were performed and used to scale the 3D model.
Low Resolution Model: 75K Facets - Image Texture Size:1024^2 Medium Resolution Model: 250K Facets - Image Texture Size:4096^2 High Resolution Model: 1M Facets - Image Texture Size:8192^2 Resolution: ~3cm (between consecutive points distance in raw data model)
