The minaret of Rotunda, built in the end of the 16th century, when the Ottoman Sinan Paşa and the sheikh of the nearby dervish community, Hortaci Süleyman Efendi, converted the building into a mosque named after the latter. It is the only remaining minaret from the ottoman mosques in the city and it is located in the southwest corner of the building. It 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. The terrestrial photoshooting session 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.
