Abstract

Digital photogrammetry, especially through the use of drones, has proven to be an efficient, accurate, and low-cost alternative for mapping damage on the facades of historical buildings. This paper presents a case study applied to the Solar do Barão de Itapura, in Campinas, São Paulo, aiming at the creation of a detailed orthophoto with the identification and classification of pathological manifestations. The methodology includes visual inspection, flight planning, image capture, point cloud processing using Agisoft Metashape Pro software, and analysis of the generated products such as 3D meshes and orthophotos. The results demonstrate the applicability of the technique as an auxiliary tool for identifying and diagnosing pathological conditions in heritage building facades, enabling more well-founded restoration interventions.
