摘要

This paper presents a virtual methodology based on the generation of virtual models of stones in the context of the virtual laboratories for the acquisition and evaluation of competences in stones identification. The generation of the models is carried out using a procedure based on close-range photogrammetry that allows to obtain a scaled mesh models with radiometric information and low file weight. The proposed methodology has been designed ad-hoc following the economy, quality and reality criteria to ensure a good adequacy, guaranteeing an adequate adaptation to the teaching-learning process and the integration of the models into working packages, which can be easily integrated in earning management system (LMS) platforms. The generated 3D models have a high level of detail and enable the interaction to take measurements, make cross sections and use specific tools that allow the student to perform a thorough analysis and identification of the stone using free/open source software.
