The needs of today's society for urban planning require realistic 3D representations of objects or cities for various purposes. The topicality of the study is given by the fact that digital recording of cultural heritage objects represents one of today’s society preoccupation for purposes such as maintenance, reproduction multimedia tools for education and dissemination, to artefact condition monitoring. Analysis in a virtual world, using 3D models, for historic buildings or ancient fortresses is much more efficient than a classical 2D analysis. Thus, the aim of this study was to make a comparison between processing digital images to obtain a 3D model of an object using, in the first case, a specialized, widely used software, and, in the other cases, different open-source specialized software. The object studied was the statue of General Ion Dragalina located in Dragalina Park in Caransebeș municipality, western Romania. To process the digital images, four specialized programs were used: Agisoft Metashape, 3DF Zephyr Free, Regard 3D and Meshroom together with Meshlab. Finally, the advantages and disadvantages of each of the programs studied are highlighted by comparison.
