DRONI PER LA MODELLAZIONE 3D E PER L’INDIVIDUAZIONE DEGLI AMMALORAMENTI NELLE PAVIMENTAZIONI STRADALI

Abstract

The deteriorations of road infrastructure, that is, the loss of initial performance in the aftermath of vehicular traffic, both in the assessment of functional status and in natural agents (frost-thaw, earthquake, salty, etc.) has led to the need for development of non-destructive tests designed to provide useful elements without damaging the work. Pavement damages are one of the major causes of road accidents. In view of this criticality, it is necessary to devise an effective pavement maintenance management system with respect to economic constraints with the aim of ensuring adequate standards. Certainly an careful visual analysis is the basis for a correct evaluation of the conditions of the work being observed. In this respect, this note deals with a system for the production of 3D models based on the acquisition of digital images, by means of an automatic flight drone, applied to the analysis of a road infrastructure located in the territory of the Province of Reggio Calabria. Later processing of images was carried out via commercial software, based on special Structure from Motion (SfM) techniques. The SfM is a significant advance in the field of both aerospace and terrain, with results, timing and quality, comparable to those obtainable through more traditional data acquisition methods.
