Scientists of South Ural State University have engineered a unique photogrammetric system for high-precision, noncontact measurements of 3-D coordinates, which can create 3-D models of ancient cultural monuments. The researchers plan to use this system in archaeological studies of Ignatievka Cave, located in the southern Ural Mountains, where cave drawings were found in 1980.
