ADAPTIVE WEIGHTING of IMAGE OBSERVATIONS for SELF-CALIBRATION with FISHEYE IMAGES
(2021-06-17)
Fisheye cameras have been widely used in photogrammetric applications, but conventional techniques must be adapted to consider specific features of fisheye images, such as nonuniform resolution in the images. This work ...
Geometric model of a dual-fisheye system composed of hyper-hemispherical lenses
(Universidade Estadual Paulista (Unesp), 2020-03-03)
A combinação de duas lentes com FOV hiper-hemisférico em posição opostas pode gerar um sistema omnidirecional (FOV 360°) leve, compacto e de baixo custo, como Ricoh Theta S e GoPro Fusion. Entretanto, apenas algumas técnicas ...
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 ...
