Three-Dimensional Geometric Model for Rock Masses from Photographs and the Octave Program: Cantera Santa Rita, Medellín, Colombia

The present article exposes the procedure to achieve the three-dimensional geometric model of a rock mass from a pair of photographic shots made with a current camera, use of free/open software such as Octave and other free libraries, construction of equipment and simple tools and the appropriation...

Se describe tomando como ejemplo el modelo tridimensional de un corte de voladura del macizo rocoso de la Cantera Santa Rita, localizada al sudoeste de la ciudad de Medellín (Colombia). Finalmente, se muestra mediante una validación, a partir de medidas de campo in situ, que el procedimiento descrito aquí es promisorio para que pueda instaurarse como una herramienta para la caracterización geométrica de discontinuidades de los macizos rocosos.application/pdfspaUniversidad EAFIThttps://publicaciones.eafit.edu.co/index.php/ingciencia/article/view/5223https://publicaciones.eafit.edu.co/index.php/ingciencia/article/view/5223Copyright © 2019 Ludger O.
