Levantamiento topográfico con escáner láser terrestre del arte rupestre en el parque arqueológico las piedras del Tunjo-Facatativá

Abstract

The objective of this project is to generate three-dimensional models through a cloud of points, of the rockies and more representative cave painting of the archaeological park las piedras del Tunjo, in Facatativá Cundinamarca; with these 3D models it is possible to preserve the information contained in the pictographies that each one of the stones contain and facilitate the investigations that require to realize these archaeological vestiges. To carry out this project, a survey with laser scanner was carried out, of six (6) park`s rocks, which have the largest amount of pictographic information. To geo-reference them, was needed to realize a polygonal and measure as details the points where the spheres were placed. The methodology in the office consisted mainly of the cleaning and georeferencing of the scenes taken by the laser scanner, with the specialized Scene software, and finally, a detailed archaeometric analysis was performed with the Autodesck Recap software on the orthophotos generated in Scene. The students of the technology in surveying program realize this project to support the research of the investigation group in archaeoastronomy.
