Restitución de datos láser escáner para el análisis del deterioro de bóvedas de ladrillo

The research, based on a real case, analyses the subsidence of the brick vaults. The goal is to identify a method of plotting data capable of detecting the critical zones of the vault, subject to further and detailed investigation. In order to avoid a preliminary investigation of the vault with moderate vibration, it will be illustrated the possibility to implement a laser-scanner to code a procedure capable of detecting areas potentially damaged. Through the transformation of point clouds in CAD data, it has been possible a further analysis of critical areas of the vault soffit down to the last centimetre. Drawing the deformations with different colours, based on the intensity of the subsidence, it has been possible to obtain a new representation, which clearly displays the critical areas. The results will be compared through the use, for example, of endoscope, to validate the method, and the representation and the use of the laser-scanner in the analysis of sagging of the brick vaults. In conclusion, it will be illustrated the use of Rhinoceros for future applications: the 3D modelling will be used for a more specific analysis of the curvature of the vault
