Abstract

Laser scanner methodology is evaluated as one of the most efficiency survey tecnique for the production of tridimensional digital models: it allows to obtain high precision and high volume data with low costs and short time. This methodology was adopted for the tridimensional survey of Santo Sepolcro Church, belonging to the whole monumental of Santo Stefano Church in Bologna. This object has been chosen for the great historical architectural interest of the sanctuary, which needs of metric information and morphologis. 17 terrestrial laser scans have been acquired into the Santo Sepolcro Church with the goal to reconstruct the 3D model of the main central structure. The Cyrax 2500 laser scanner for the acquisition of points clouds and the Cyclone software for the alignment of the scanning have been used for the morphometric survey. The co-registration of the scanning has been performed using high reflectivity artificial targets: the coordinates of the targets have been acquired by the total station TC 2003 in order to register the points clouds in the same local reference system.
