Geometric Calibration of a Hyperspectral Frame Camera
(2016-09-01)
Recently, miniaturised hyperspectral sensors operable from small unmanned airborne vehicle platforms have entered the market. The emerging hyperspectral imaging technologies, based on frame cameras and tuneable filters, ...
A influência das injunções de orientação relativa na calibração de um sistema dual de câmaras digitais
(2009-10-21)
Image acquisition systems based on multi-head arrangement of digital frame cameras, such as the commercial systems DMC, UltraCam, besides others, are attractive alternatives enabling larger imaging area when compared to a ...
Line based camera calibration in machine vision dynamic applications
(1999-12-01)
The problem of dynamic camera calibration considering moving objects in close range environments using straight lines as references is addressed. A mathematical model for the correspondence of a straight line in the object ...
The influence of subpixel measurement on digital camera calibration
(2012-09-10)
The aim of this work is to evaluate the influence of point measurements in images, with subpixel accuracy, and its contribution in the calibration of digital cameras. Also, the effect of subpixel measurements in 3D coordinates ...
Generating virtual images from oblique frames
(2013-04-01)
Image acquisition systems based on multi-head arrangement of digital camerasare attractive alternatives enabling a larger imaging area when compared to a single framecamera. The calibration of this kind of system can be ...

Image acquisition systems based on multi-head arrangement of digital frame cameras, such as the commercial systems DMC, UltraCam, besides others, are attractive alternatives enabling larger imaging area when compared to a ...
Calibration of a catadioptric omnidirectional vision system with conic mirror
(2016-03-01)
Omnidirectional vision systems that enable 360° imaging have been widely used in several research areas, including close-range photogrammetry, which allows the accurate 3D measurement of objects. To achieve accurate results ...
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 ...
