Photogrammetry software for hobbyists produced high inaccuracy when merging interior and exterior - They didn’t fulfill requirements for geodetic documentation.

With other professional photogrammetry software packages the manual labor was required.

However, for capturing the inaccessible parts of the roof this data source was sufficient.įrom each tested photogrammetry software, the RC was the only software that produced detailed and accurate model fully automatically. It was chosen for two reasons: the size of the drone and the speed of data capturing. Note: When it come to quality of the resulting data, the use of video from the drone is not an ideal solution. 3 control points were used to check the quality of merging interior and exterior, measured with total station, polar methodĪ/ 160 images of the exterior ( Canond EOS 5D Mark IV) The images were taken in raw format with 24mm lens.ī/ 102 images of the interior of the church ( Canond EOS 5D Mark IV) The images were taken in raw format with – 31 images with 11 mm lens and 71 images with 24 mm lens.Ĭ/ 2 short video sequences from drone for capturing parts inaccessible from the groundĤK video shot at 30 fps – Realit圜apture then created 523 images for processing.4 ground control points were used in exterior for scaling and georeferencing.Robust software for processing – during this project 4 different photogrammetry software have been compared and only Realit圜apture enabled fully automatic calculation producing detailed and accurate result.

The high efficiency of this method is due to the low cost of technology and in the speed of gathering the data and creating the digital copy of the object of interest. The exterior and interior of the building can be scanned very well and above all, very quickly. In fact, it has been proven that by using appropriate methods of the image capturing and by using robust software (RC), laser scanning can be completely replaced. In both cases, only photogrammetry (terrestrial + video from the drone) was used for 3D documentation. Given the Christian roots of the Czech Republic and the fact that Armenia is the oldest country to embrace Christianity as its state religion (301 AD), the attention is focused on the amazingly preserved Christian architecture.īoth churches (smaller ones dedicated to Virgin Mary and Great Cathedral) are located near the city of Talin, in the province of Aragatsotn. Parties involved in this project are experts from organization Our History (Nase Historie) Academy of Sciences of the Czech Republic in Prague and Academy of Sciences of Armenia in Yerevan. Project „Hayastan“ is a Czech - Armenian archaeological expedition focused on preserving Armenian cultural heritage by using non-destructive methods of archaeological research (geophysical measurements, topographic - geodetic survey, aerial archaeology, etc) and modern methods of 3D documentation of important historical monuments. An example shown on a 7th century church located in Talin, Armenia.
