Abstract
ABSTRACT Palaeolithic graphic activity documentation is essential not only for its preservation and dissemination but also for its scientific analysis. Nowadays, researchers can use advanced techniques such as photogrammetry, lidar, or structured light scanning to record this heritage. However, there is a lack of studies comparing these three technologies. Therefore, this article presents a comparison of these techniques based on three variables: namely, time employed, geometric reconstruction, and resolution. The study examines how these factors affect the final result of the digital recording of rock art. A mold of Rock 11 from Domingo García (Segovia, Spain) and the archaeological panel S.4 from La Salud (Salamanca, Spain) have been used as test control examples. The results indicate that photogrammetry using a DSLR camera is the most efficient technique, providing the necessary reconstruction to obtain scientific data.
