Geociências virtuais parâmetros de calibração dos equipamentos para a captação de imagens e construção de modelos 3D

Abstract

The Virtual Geosciences Revolution is the process of digital transformation that has been underway in recent years in the analysis of data from rock outcrops in the area that covers scientific disciplines on the study of the Earth. In an older form, geological information has always been acquired in person, as is the case with the first geological maps and outcrops described. Technological development and the intensive use of computational tools allow new techniques to be employed in the acquisition of geological data currently performed remotely. The integration of geological data throughout history has traditionally been done in 2D (columnar profile, maps, Cartesian graphs, geological sections), currently due to the advancement of technology there are techniques accessible to the entire community, which have become important tools for a constant revolution in the geosciences. The use of virtual tools has grown progressively in recent decades, which makes it possible to apply them in the most diverse human activities. In the geosciences, virtual tools have revolutionized the way geological information is acquired on the Earth's surface, allowing the extraction and integration of large volumes of 1D, 2D and 3D data. Virtual outcrop models (MVA) are photorealistic 3D projections of the surface of rock outcrops with millimeter to centimeter resolution and that allow the extraction of a series of geological information that can be structural, stratigraphic and textural, among others. This work aims to demonstrate techniques and applications in the acquisition of images for the creation of 3D models remotely in virtual geosciences, demonstrating equipment calibration techniques for high-quality capture in the generation of 3D models, in addition to the use of the best results in acquisitions and applications aimed at teaching, research, outreach, and use in the geological heritage of the UNESCO World Geopark Caçapava, using materials and methods that can be accessible.
