AbstractThe purpose of this work was to develop data from photogrammetric flight using an UAV with a non-metric camera. Due to the specific subject of the present study, it was necessary to review the software available on the market, one that would provide the opportunity to model specific objects such as architectural structures, with satisfactory results. As a result, a 3D model of the eastern façade of the church of Saint Charles Borromeo in Wrocław was obtained. The use of UAVs for this type of measurement is an innovative method that allows quick, secure and relatively cheap data acquisition. The article presents subsequent steps in the development of non-metric photogrammetric data. The model obtained from photographs taken by the UAV was subjected to accuracy analysis using a tachymetric measurement fitted into this model. Equipping the model with georeferencing consisted in determining coordinates of characteristic points, thanks to which it was placed in the local coordinate system.
