AsTrend, ancient carvings enhanced

AsTrend

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…
