Quantifying hail size distributions from the sky - Application of drone aerial photogrammetry
(Copernicus Publications, 2020-02)
A new technique, named "HailPixel", is introduced for measuring the maximum dimension and intermediate dimension of hailstones from aerial imagery. The photogrammetry procedure applies a convolutional neural network for ...
Comparação de métodos de levantamento topográfico, utilizando escâner a laser, estação total e fotogrametria terrestre
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Construção Civil, 2015)
The study compares three methods of surveying used to collect data from a public road trench.The first method used was total station, which collects the data with the aid of a prism. The Prism was placed in 8 points ...

(Lexis, 2018-02)
3D images are increasingly used in the documentation of Cultural Heritage. The Laboratory of Laser Ablation of the Centro de Investigaciones Ópticas, Argentina, is carrying out a 3D digitization project of the collections ...
Photonic Methods Applied to Heritage Conservation in Argentina
(University of Iasi Publishing House, 2017-12)
As part of an ongoing program performed in collaboration with museums and institutions of Argentina, we present results on the application of laser based techniques and 3D imaging methods for material characterization, ...
Aerotriangulação por faixa e em bloco, por aplicação de software especialista, com medições de coordenadas fotográficas em mesa digitalizadora
(Universidade Federal de Santa MariaBRGeociênciasUFSMPrograma de Pós-Graduação em Geomática, 2007-05-11)
In the elaboration of maps, one of the processes broadly employed is the photogrametric restitution. But for accomplishment of this process it becomes necessary to have, on each stereoscopic pair, terrestrial coordinates ...
Applications of low-cost 3D imaging techniques for the documentation of heritage objects
(Sociedad Española de Óptica, 2018-05)
3D image recording has reached an increasing impact on the field of cultural heritage. Applications include documentation of the state of conservation and dimensions of an object, the archaeological survey of artefacts, ...
Avaliação experimental de técnicas de calibração de câmaras com objetiva olho de peixe
(2015-01-01)
Fisheye lens cameras enable to increase the Field of View (FOV), and consequently they have been largely used in several applications like robotics. The use of this type of cameras in close-range Photogrammetry for high ...
