Aerofotogrametria como auxiliar na inspeção e identificação de danos em edifícios históricos

Abstract

This paper discusses using of Remotely Piloted Aircraft (RPA) as an aid for inspection and damage identification in historic buildings, through aerial photogrammetry and digital modeling techniques. The case study is the inspection of the roofs of the chapels of the Sanctuary of Bom Jesus de Matosinhos, in Congonhas/MG. Flight planning is presented, considering issues such as stability and operational safety. The method involved image processing in a specific aerophotogrammetry software and the presented results deal with damage identification of to the roofs and three-dimensional digital modeling of the Sanctuary. The article concludes that the use of RPAs enables inspections in places of difficult access, and that aerial photogrammetry associated with other methods, such as the use of laser scanners, can enable surveys of buildings of cultural interest in a precise, low-cost , efficient and faster way.
