From Reality to Point Clouds. Survey and Analysis of Sant Miquel Church of Batea (Spain)

Abstract

. Current massive data capture techniques (MDCT), such as terrestrial laser scanning and digital photogrammetry, have become widespread during the last decade, and raises the possibility of developing new assessment methodologies based on the 3D documentation. The paper exposes de results of using simple, non-invasive procedures for the assessment of the shape of a masonry building from a point clouds registered with a terrestrial laser scanner. The case study selected is the church of Sant Miquel of Batea (eighteenth century), located in the province of Tarragona (Spain). The methodology used combines 2D and 3D processes for assessment of the geometry. The results of the investigation have confirmed the good condition of the building. It presents dimensional variations, most of which can be related to the construction process, while some displacements identified provide information about the accommodation process of the masonry structure.
