Integrated Survey for Tensional Analysis of the Vault of the Church of San Nicola in Montedoro

Abstract

<p><strong>Abstract.</strong> This paper presents some of the results obtained from the integrated use of 3D surveying techniques and illustrates some types of analysis and graphic representations that can be conducted and reproduced. The case study concerns the church of San Nicola in Montedoro that is one of the oldest in the city of Martina Franca in the province of Taranto (Italy) and presumably dates back to the fourteenth century. The work consists of a survey with different integrated methodologies, the creation of thematic tables all in order to allow a structural analysis.</p><p>The contribution shows how this approach is not intended for a single case study, but starting from it can be extended to other contexts that present similar criticality and potential, often recurrent in the field of the survey and representation of cultural heritage.</p>

An Efficient Pipeline to Obtain 3D Model for HBIM and Structural Analysis Purposes from 3D Point Clouds

“…The creation of surfaces suitable for the modelling of objects or structures starting from a 3D "dense point cloud" model (obtained through geomatics surveys) can take place in different ways. Several pipelines have been examined [1,19]: the most efficient of these (in terms of linearity of the method, accuracy, processing times) can thus be schematized ( Figure 1). In fact, should the model generation take place in Revit, it would require the generation of families responding to the geometric characteristics of the object.…”

“…The interior consists of a single room and has two baroque altars in stone. On the walls, frescoes are visible, painted on two layers ( Figure 2d) [1].…”

“…Modern surveying technologies in cultural heritage (CH) offer new perspectives of application both as regards the acquisition of metric data and the representation or analysis of objects of historical and artistic interest [1]. In this way, it is possible to obtain a digital representation of objects or structures belonging to the CH environment in terms of position, shape, geometry and description of each element.…”

Multi-Sensor Image and Range-Based Techniques for the Geometric Documentation and the Photorealistic 3D Modeling of Complex Architectural Monuments

“…Another disadvantage that most of the active sensors present is the lack or the low quality of texture information, which is usually acquired with a separate digital camera and registered afterward onto the laser scanning data for a complete texture mapping [13] (p. 199). The integration of the two datasets is usually an approach that can lead to optimal results in complex structures or sites [14] (p. 455).…”
