Monitoring the health of an emblematic monument from terrestrial laser scanner

Abstract

This paper deals with the application of terrestrial laser scanner technology to the health monitoring of a monument in the World Heritage List. Specifically, this monument is a mediaeval wall located in Avila, Spain. The main aim of the paper is to show the relevance and novelty offered by the laser scanning methodology developed, which incorporates different statistical and modelling approaches not considered until now. In addition, the methods proposed in this paper together with the obtained results allow the measurement of entire structures or deformed shapes in buildings. The accuracy of our methodology compared to surveying methods proved satisfactory. Thus, they have been useful not only to show its viability but also to secure and maintain the safety and serviceability of this emblematic monument.

Terrestrial laser scanning intensity data applied to damage detection for historical buildings

“…The geometrical information provided by the coordinates of these points has been successfully applied in a number of diverse fields such as archaeology (Lamberts et al, 2007), civil engineering (González-Aguilera et al, 2008b), geology (Buckley et al, 2008) and geomorphological analysis (Armesto et al, 2009). One of the most widespread applications is the documentation of heritage sites (González-Aguilera et al, 2008a;Guidi et al, 2004;Sharaf et al, 2009). Radiometric information provided by the intensity measurement is used less frequently, although the use of the intensity data is increasing.…”

Recognition of materials and damage on historical buildings using digital image classification

“…[17][18][19][20][21] One of the most important applications is the preservation and restoration of historical buildings. [22][23][24][25] Our case study applies to the Santa Marina de Aguas Santas Church in Córdoba (Spain). This church is a historical building dating back to the 13th century and is of great cultural heritage value.…”

Photogrammetric 3D modelling and mechanical analysis of masonry arches: An approach based on a discontinuous model of voussoirs

“…Virtual reconstruction of real world objects and scenes for further analysis is getting increasing interest in several fields as heritage [7], construction technology [8], medicine [9], and computer vision [10].To obtain the geometry used for computations, photogrammetry and laser scanning techniques are of interest to several researchers in the fields of structure inspection and computation [11,12], especially photogrammetric techniques because they are more balanced in terms of cost and accuracy.…”
