3d Survey of Pre-Hispanic Wall Painting With High Resolution Photogrammetry

Abstract

ABSTRACT:The survey and representation of pre-hispanic wall painting use to be done with traditional photography, we describe the difficulties and limitations found in this approach and we show another solution to improve the quality of this documentation. It relies on the use of photogrammetry and MicMac program. The calculated orthophotos have an accurate geometry, they are high resolution and the three-dimensional models present a high level of detail. We obtain a complete representation which satisfy the requirements of art historians and conservators to study the meanings of the paintings and their conservation state. Furthermore, as this improvement is achieved by following a particular strategy for the photo sessions and the mathematical processing on the images, it doesn't need the acquisition of additional equipment. We explain how we applied the method in the registration of a structure covered with pictorial representations that was discovered in the archaeological site of Las Higueras, México.

Maximizing the Value of Photogrammetric Surveys in the Conservation of Wall Paintings

“…However, both a wall painting's size (necessitating a large number of images) and irregular surfaces make it difficult to ensure that each image is in focus and within the depth of field. Zhang et al 2011, Lucet 2013, and Vidman et al 2011 were challenged by the topography of wall paintings, noting that areas of the paintings fell beyond their depth of field.…”

3D Scanning: A Comprehensive Survey

“…1) Pre-Hispanic Wall Painting: In [70], the use of photogrammetry for creating a 3D reconstruction of the Las Higueras architectural structure has been described. The photographic survey was made with a Canon EOS 5D Mark II camera with a resolution of 21.1 Mega-pixels.…”
