Quantitative comparison between visual and UAV-based inspections for the assessment of the technical condition of building facades

In this chapter authors conduct a case study analysis in order to evaluate the potential benefits of using Unmanned Aerial Vehicles (UVAs) for the data collection involved in the failures diagnosis of facades. A quantitative approach is performed by testing for statistically significative differences between the proposed methodology and traditional visual inspections. Results allow to state that a highly significative global improvement for the data collection exists.
