Abstract

A method for quantitative high resolution 3D documentation and investigation of surface structures is presented for which two closely related techniques have been combined: photogrammetry and optical profilometry (fringe projection technique). While the latter is particularly suitable for achieving large quantities of 3D data from limited areas photogrammetry allows a very precise measurement of single points in a wide field. By integrating these methods large surfaces decorated with rock art can be acquired with high resolution. For further evaluation range images are computed which render 3D data as a virtual image where each pixel represents a height value. The example of the gallery-grave at Züschen/Lohne in Hesse, Germany, demonstrates the capabilities of the method.
