O Processamento de imagens em 3D, da arte rupestre, do Sítio Templo dos Pilares, Alcinópolis - Mato Grosso do Sul

Abstract

The Rock Art is in constant danger against its own "disappearance", caused by situations of impact to the environment in which it is inserted and by actions of vandalism in its structures. Due to these constant aggressions, to obtain information about the resulting human activities that resulted in paintings and engravings on the rocks, and to transport them from the field to the laboratory so that they can be analyzed in the perspective of understanding the intentionalities of the different human groups that produced them , it is necessary to improve the techniques used by archaeologists and archaeologists to obtain and analyze them. The present research aimed to investigate new techniques of digital recording from the combination of the use of 3D image processing performed in Agisoft Photoscan as a tool in the processing of the data obtained still in the field of rock art images existing in the municipality of Alcinópolis in the state of Mato Grosso do Sul. Therefore, more than collaborating for the technological advance in the production of data on rock art, it is an important tool that allows the combination of several digital techniques like Photoshop, Lightroom and Photoscan, more accurate metric reproductions (depth, color, size) are from shelters, panels, caves, or other rocky supports that broaden interpretations of human presence in the state. This perspective becomes relevant insofar as this set of software becomes a subsidy to achieve a high quality of images, and contributes in the production of more accurate data on rock engravings, in comparison to the old techniques. These software are being used in the archaeological site of the Temple of the Pillars, located in the municipality of Alcinópolis-MS, where, through terrain topographies, digital photos, laser measurements and geographic coordinates, it was possible to draw a rough outline of the two shelters on rock and rock panel In addition to this factor, it is possible to recognize other possibilities of studying the archaeological data, mainly art and rock drawings obtained in the field from three-dimensional images generated in the Agisoft Photoscan software contributing to the study of archaeological cultural heritage. The three-dimensional images are a new way of conserving, preserving and valuing the archaeological heritage, without invasive actions to the environment in which it is inserted, and at the same time offers tourist potential for the region, as it helps to value cultural assets and allows to represent a contemporary historical moment. The images will serve as a basis for the development of actions aimed at Education at all levels, Patrimonial Education, and promotion of tourism, in addition to sensitizing the population to the cultural assets present in Alcinópolis / MS.
