During archeological discoveries one often encounters unfavorable terrain conditions, in those cases digital photogrammetry seems to be the most suitable method for object documentation. This thesis specifically describes a method of image scanning in which the software product, based on the taken digital images, in an automated way orientates those images in the respective area, resulting in generation of a 3D spatial data. Accuaracy of generated 3D models depends on appropriate selection of snaphosting standpoint configuration and also from quality of taken images. Part of the thesis is a comparisson of generated 3D spatial datasets in dependency from used snapshot configurations and from various settings in the software product PhotoScan developped by Agisoft LLC.
