Creating an Interior 3D Model of a Church

The paper deals with the 3D modelling based on photos. The target object is an interior space of a church. The photos were taken with a DJI Phantom Advanced UAV. Since the GPS receiver is not available inside buildings, the photos were taken in manual mode. In order to organize the shooting positons into vertical strips, the photos were taken from three different stations from different vertical positions. The 3D model was built with AgiSoft PhotoScan software. The camera calibration was carried out prior the processing to ensure a higher accuracy. The scale of the model was setup by reference distances and points. The experiments showed us, that the created model is suitable not only for demonstration and artistic purposes, but for engineering measurements as well.
