Methods of short-range digital photogrammetry and unmanned aerial vehicle imagining increasingly find more extensive usage in various types of measurements. In recent years, modern photogrammetric technologies have found wide application in recreating 3D models of any objects. The resulting 3D models can be a source of information that may be used for measurement, inventorying and cataloguing, as well as for visualisation purposes. New methods of acquiring spatial data have been developed, such as laser scanning, imaging using unmanned aerial vehicles or digital non-metric cameras. Synergy and the confluence of these data have expanded the existing measurement possibilities, finding application in 3D modelling, inventorying of monuments, or monument conservation. Photogrammetric methods are comparable to direct measurement methods in terms of their accuracy, as well as speed and cost. They have a number of advantages, including a shortened time required for taking a photo, which is greatly convenient when measuring moving objects. Other advantages of photogrammetric methods include the possibility of development and performing measurements in chamber conditions and the lack of restrictions pertaining to repeating the measurement when errors are found or a need arises to supplement them [Kurczyński and Preuss 2000]. One of the possibilities offered by photogrammetry is the ability to create 3D visualizations. The creation of a three-dimensional model facilitates presenting the inventoried object in a realistic, complete, and up-to-date manner. This paper presents an attempt to synergise data for modelling a three-dimensional architectural object based on photos obtained with the Nikon D7500 non-metric camera and with the DJI Mavic Air unmanned aerial vehicle.
