Modelling building costs from 3D building models - estimating the construction effort from image-based surface models of dry-stone sheperd shelters (Kras, Slovenia)

In the second half of the 19th and early 20th century, sheep shepherds have built dry-stone shelters all over the Slovene Kras (or Karst) region. Despite being made out of stones that are interlocked without the use of any binding material, many of …

Taking vegetation marks into the next dimension: Mapping the hilltop settlement of Montarice (central Adriatic Italy) by a multi-dimensional analysis of aerial imagery

The processing of aerial imagery acquired over Montarice hill (central Adriatic Italy) during the Potenza Valley Survey will form the key focus of this paper. Since this site has repeatedly revealed itself in terms of interesting vegetation and soil …

Computer graphics meets image fusion: The power of texture baking to simultaneously visualise 3d surface features and colour

Since a few years, structure-from-motion and multi-view stereo pipelines have become omnipresent in the cultural heritage domain. The fact that such Image-Based Modelling (IBM) approaches are capable of providing a photo-realistic texture along the …

Documenting Bronze age Akrotiri on Thera using laser scanning, image-based modelling and geophysical prospection

The excavated architecture of the exceptional prehistoric site of Akrotiri on the Greek island of Thera/Santorini is endangered by gradual decay, damage due to accidents, and seismic shocks, being located on an active volcano in an earthquake-prone …

Unfolding Leonardo da Vinci's globe (ad 1504) to reveal its historical world map

This paper reports in detail on the image-based modelling and unwrapping approach used to create a two-dimensional projected map of an astonishing ostrich egg globe from AD 1504. This miniature egg globe is not only the oldest extant engraved globe, …

Mind your grey tones -- examining the influence of decolourization methods on interest point extraction and matching for architectural image-based modelling

This paper investigates the use of different greyscale conversion algorithms to decolourize colour images as input for two Structure-from-Motion (SfM) software packages. Although SfM software commonly works with a wide variety of frame imagery (old …
