Comparison between two radiometric calibration methods applied to UAV multispectral images
(2020-01-01)
There are many advantages of using unmanned aerial vehicles (UAVs) in remote sensing but when using radiometrically corrected multispectral images. This study focuses on two techniques of obtain a multispectral orthomosaic ...
Exterior orientation of hyperspectral frame images collected with UAV for forest applications
(2016-03-17)
This paper describes a preliminary study on the image orientation acquired by a hyperspectral frame camera for applications in small tropical forest areas with dense vegetation. Since access to the interior of forests is ...
Shadow detection in hyperspectral images acquired by uav
(2019-06-04)
Shadows are common in any kind of remote sensing images. Unmanned Aerial Vehicle – UAV with a light camera attached can acquire images illuminated either by direct sunlight or by diffuse light under clouds. Indeed, ...
Performance evaluation of sequential band orientation by polynomial models in hyperspectral cubes collected with uav
(2019-06-04)
A study on orientation of hyperspectral band cubes acquired with frame camera is presented in this paper. The camera technology is based on a tuneable Fabry-Perot Interferometer (FPI) and captures cubes of images sequentially ...
Mapeamento de falhas em cana-de-açúcar por imagens de veículo aéreo não tripulado
(Universidade Estadual Paulista (Unesp), 2021-02-22)
Mapear falhas em canaviais de forma precisa por imagens UAV é um desafio, ainda mais quando não há informações sobre a qualidade das imagens e o momento ideal para capturar as imagens. Neste estudo, nós avaliamos os impactos ...
