Protocolo metodológico para levantamento de dados matriciais (imagens) com veículos aéreos não tripuláveis (VANT).

Abstract

Currently, the use of low-cost Remotely Piloted Aircrafts (RPAs), popularly known as drones, in monitoring and supporting decision-making within space management becomes a promising tool, the recent advances in legislation for its use in aerial photogrammetric surveys. However, the methodologies for applying this new technology need to be both systematized and democratized, requiring pre and post-flight procedures that minimize experimental errors and validate methodological procedures that ensure application safety and control imperfections of final products, thus increasing its quality. Therefore, the objective of this work was to construct a methodological "protocol" for the collection of low-cost UAVs (images) with local space clippings. When working with a VANT that, in essence, was not designed for aerial photogrammetry, such as DJI Phantom 3 - Professional, used in this research, to verify if these devices, although with some limitations, could generate great precision , as well as high accuracy for the 1: 1000 PEC-PCD Class B and PEC-PCD Class A 1: 5000 scales, always paying attention to the use of these products. In addition, the construction of the methodological protocol contributes to the systematization and democratization of geoprocessing as a research tool for any and all areas that require spatial data.
