NAQ1 virtual tour door

October 9, 2020: on the occasion of the European Day of Rock Art it is a real pleasure to invite enthusiasts and scholars to visit the Great Rock of Naquane in Valcamonica and to surf over it. Just find the door, open it with a click, and enter the virtual tour. The Great Rock is the most richly engraved of the Park. You can move along the wooden walkways just as if you were doing a real visit: you can closely observe the surface, discover every detail, navigate by moving like a bird’s eye, approaching and moving away at will. So, feel comfortable in your home, and start your virtual journey inside Naquane and Valcamonica rock art (PDF available).

NAQ1, la porta del tour virtuale

In occasione del 9 ottobre, Giornata Europea dell’Arte Rupestre, è un vero piacere invitare gli appassionati e gli studiosi di arte rupestre a visitare la Grande Roccia di Naquane e a navigare lungo la sua superficie incisa. Basta trovare la porticina, aprirla con un click ed immergersi nel tour virtuale. La Grande Roccia è la più riccamente istoriata di tutto il Parco di Naquane. Puoi muoverti lungo le passerelle di legno come se tu la stessi visitando dal vivo, osservare da vicino le scene e le figure preistoriche, scoprire ogni dettaglio, navigare tra i settori incisi muovendoti a volo d’uccello, avvicinandoti e allontanandoti a volontà. E dunque, stai comodo a casa tua e inizia il tuo viaggio a Naquane, immergendoti nell’arte rupestre della Valcamonica (PDF disponibile).

Enfrentando los dibujos… ¡otra vez! (Perú)

August 24, 2020 Academics, Featured, Imaging, South America, TRACCE Onl. RA Bull.46 No comments

With great interest I have watched the YouTube Video called: Charla Rupestre: Los Petroglifos de Chillihuay. Arequipa, Perú by Maritza Rodríguez Cerrón and Daniel Chumpitaz Llerena (21 August 2020), two leading Peruvian archaeologists who have intensively surveyed the important rock art site of Chillihuay in southern Peru. However, a couple of those drawings in their 2014-paper drew my attention, as they proved to be incorrect (PDF available).

AsTrend, ancient carvings enhanced

October 15, 2015 3D, Abstracts, Computerware, Imaging, TRACCE Onl. RA Bull.37 2 comments

AsTrend

A short outline of a new low cost methodology: we present the AsTrend, a new methodology for enhance and depict details of the 3D models. This technique is being revealed as an accurate method to study rock art carvings and inscriptions. We think that this method could be used by everyone as the main study objects are based in low cost photogrammetry on the acquisition of 3D models.

Tracing

[CAA 2015 – session 3C abstract]

The digital recording of rock art has benefited of an increasing number of software solutions, mostly photogrammetry and the enhancement of pigments from photographs. During the last years we have utilized open source scientific libraries for enhance pigments in a currently under development software code named PyDRA…

Polesini cave

[CAA 2015 – session 3C abstract]

Traditional 3D recording requires expensive equipment as the laser scanning systems, with complex and highly specialised software. These problems may be partly overcome by applying a consolidate technique generally used in quality controls within manufacturing industrial environments: the photometric stereo…

Campo Lameiro

[CAA 2015 – session 3C abstract]

We propose photogrammetry as a technique that allow us to create a 3D model, oriented to reduce the different problems of subjectivity that are present in the old systems of registry, and furthermore to study the rock surface without touching it…
