Digital Models of Stone Samples for Didactical Purposes

Abstract

<p><strong>Abstract.</strong> 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.</p>

Suitability of Automatic Photogrammetric Reconstruction Configurations for Small Archaeological Remains

“…Both were chosen for their intuitive software interfaces and available documentation about use. The present approach is significant for three main reasons: aids in the reconstruction of small archaeological parts for documentation purposes [52]; helps assemble dismantled heritage elements and/or missing parts [29]; and generates didactical models for the acquisition of competences in an e-learning context [53] and can be included in products like augmented or virtual reality (AR/VR) applications for awareness-raising [6].…”

Buildings 360º: un nuevo enfoque para la enseñanza en construcción

“…Conjunto de enfoques que pivotan fundamentalmente en el uso de modelos 3D, con mayor o menor grado de detalle, del objeto de interés. Ejemplos de estas aplicaciones pueden verse en multitud de estudios, efectuados a diferentes escalas e incluso en diferentes titulaciones Rodríguez- Gonzálvez et al (2019). incorpora las mallas 3D de materiales pétreos como parte de la evaluación de conceptos en asignaturas donde el reconocimiento de las mismas es parte fundamental del aprendizaje Rodríguez-Martín et al (2019).…”
