Abstract
The purpose of this work is to create a three-dimensional model of the terrain on the territory of the Hasti-Imam ensemble of the city of Tashkent (Uzbekistan), using a Geoscan 401 multi-rotor unmanned aerial vehicle and a modern photogrammetric product Agisoft Metashape. Four flights were performed at this facility using a Geoscan 401 quadcopter. Aerial photography was carried out at different heights (from 40 m to 100 m) and with different inclinations of the aerial camera (45°, 60°, 90°) in order to display all elements of the ensemble in more detail. Aerial photography was carried out at a scale of 1:500 using a SonyDSC-RX1 digital aerial camera with a focal length of 50 mm. The longitudinal overlap of aerial photographs was from 70% to 80% and, accordingly, the transverse overlap was also from 70% to 80%. The number of aerial photographs at the site was 936 pieces. The length of all air routes was 65.9 km. The area of the filmed object was 14 hectares.The processing of unmanned aerial photography and the construction of a three-dimensional model of the terrain on the territory of the Hasti-Imam ensemble in Tashkent, Uzbekistan was carried out in the modern photogrammetric complex Agisoft Metashape.
