Abstract

Computational extraction and analysis of information contained in digital photo sequences now allow non - computer specialists to build information rich, scientifically reliable, digital representations of rock art. These representations enable 3D measurement, interactive relighting, and viewing from any angle, and the mathematical enhancement of rock art surface features on outdoor surfaces, in caves, and in the laboratory. Data acquisition is easy to learn, compatible with existing working cultures, and requires only affordable digital camera equipment. Provenance metadata are saved and organized. The same photos permit the automatic rendering of technical drawings from a selection of user configurable, algorithmic, 3D filters.
