Non-invasive three-dimensional recording of aboriginal rock art using cost-effective digital photogrammetry

Inexpensive digital cameras combined with appropriate and accessible photogrammetric software are now capable of generating accurate and dense three-dimensional records of rock art using automated methods. This paper describes the development of a system of recording rock art that is portable, inexpensive, non-invasive and does not require extensive photogrammetric expertise. The effectiveness of the approach is demonstrated for two petroglyphs in New South Wales, Australia; results are presented and accuracies assessed.
